本文采用原始的rpm安装方式

基础环境：CentOS 7.5

Mysql：5.6

Percona-XtraBackup版本：2.4.11

下载的是Percona-XtraBackup-2.4.11-rb4e0db5-el7-x86\_64-bundle.tar安装包。在安装之前最好安装一些其他额外组件，例如perl-DBD-MySQL等。否则你会遇到很多缺少安包问题。例如如下：

libev.so.4()(64bit) is needed by percona-xtrabackup-24-2.4.11-1.el7.x86\_64  
    perl(DBD::mysql) is needed by percona-xtrabackup-24-2.4.11-1.el7.x86\_64  
    perl(Digest::MD5) is needed by percona-xtrabackup-24-2.4.11-1.el7.x86\_64  
    rsync is needed by percona-xtrabackup-24-2.4.11-1.el7.x86\_64

1、下载XtraBackup工具包并上传到服务器中解压安装文件

\[root@tslave tools\]\# tar -xvf Percona-XtraBackup-2.4.11-rb4e0db5-el7-x86\_64-bundle.tar  
percona-xtrabackup-24-2.4.11-1.el7.x86\_64.rpm  **--主程序安装包**

2、安装XtraBackup程序包，提示缺少各种依赖包  
\[root@tslave tools\]\# rpm -ivh percona-xtrabackup-24-2.4.11-1.el7.x86\_64.rpm              
warning: percona-xtrabackup-24-2.4.11-1.el7.x86\_64.rpm: Header V4 DSA/SHA1 Signature, key ID cd2efd2a: NOKEY  
error: Failed dependencies:  
    libev.so.4()(64bit) is needed by percona-xtrabackup-24-2.4.11-1.el7.x86\_64  
    perl(DBD::mysql) is needed by percona-xtrabackup-24-2.4.11-1.el7.x86\_64  
    perl(Digest::MD5) is needed by percona-xtrabackup-24-2.4.11-1.el7.x86\_64  
    rsync is needed by percona-xtrabackup-24-2.4.11-1.el7.x86\_64

3、安装缺少的依赖包

\[root@tslave tools\]\# yum install cmake gcc gcc-c++ libaio libaio-devel automake autoconf bzr

\[root@tslave tools\]\# yum -y install perl perl-devel libaio libaio-devel perl-Time-HiRes perl-DBD-MySQL  perl-Digest-MD5

4、再次安装XtraBackup时还提示缺少**libev.so.4()**依赖包，此包需要单独安装即可

\[root@tslave tools\]\# rpm -ivh percona-xtrabackup-24-2.4.11-1.el7.x86\_64.rpm  
warning: percona-xtrabackup-24-2.4.11-1.el7.x86\_64.rpm: Header V4 DSA/SHA1 Signature, key ID cd2efd2a: NOKEY  
error: Failed dependencies:  
   XtraBackup(64bit) is needed by percona-xtrabackup-24-2.4.11-1.el7.x86\_64

报** libev.so.4()**错误的话，需要从网上单独下载安装包安装，本环境安装版本： libev-4.15-7.el7.x86\_64.rpm

5、安装 libev-4.15-7.el7.x86\_64.rpm

\[root@tslave tools\]\# rpm -ivh libev-4.15-7.el7.x86\_64.rpm  
Preparing...                          \#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\# \[100%\]  
Updating / installing...  
   1:libev-4.15-7.el7                 \#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\# \[100%\]

6、安装xtrabackup工具，提示可以安装正常成功  
\[root@tslave tools\]\# rpm -ivh percona-xtrabackup-24-2.4.11-1.el7.x86\_64.rpm  
warning: percona-xtrabackup-24-2.4.11-1.el7.x86\_64.rpm: Header V4 DSA/SHA1 Signature, key ID cd2efd2a: NOKEY  
Preparing...                          \#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\# \[100%\]  
Updating / installing...  
   1:percona-xtrabackup-24-2.4.11-1.el\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\# \[100%\]

7、验证xtrabackup安装是否成功，输入xtrabackup命令后，会正常返回各种参数说明，则说明安装已成功

\[root@tslave tools\]\#  xtrabackup    **--输入xtrabackup可以正常有结果输出，则说明安装成功了**

                      --tables.  
  --databases-exclude=name  
                      Excluding databases based on name, Operates the same way  
                      as --databases, but matched names are excluded from

  --stream=name       Stream all backup files to the standard output in the  
                      specified format. Currently the only supported format is  
                      'tar'.  
  --compress\[=name\]   Compress individual backup files using the specified  
                      compression algorithm. Currently the only supported  
                      algorithm is 'quicklz'. It is also the default algorithm,  
                      i.e. the one used when --compress is used without an  
                      argument.  
  --compress-threads=\#  
                      Number of threads for parallel data compression. The  
                      default value is 1.

  --encrypt-key=name  Encryption key to use.  
  --encrypt-key-file=name  
                      File which contains encryption key to use.  
  --encrypt-threads=\# Number of threads for parallel data encryption. The  
                      default value is 1.  
  --encrypt-chunk-size=\#  
                      Size of working buffer(S) for encryption threads in  
                      bytes. The default value is 64K.  
  --compact           Create a compact backup by skipping secondary index  
                      pages.  
  --rebuild-indexes   Rebuild secondary indexes in InnoDB tables after applying  
                      the log. Only has effect with --prepare.  
  --rebuild-threads=\# Use this number of threads to rebuild indexes in a  
                      compact backup. Only has effect with --prepare and  
                      --rebuild-indexes.  
  --incremental-force-scan  
                      Perform a full-scan incremental backup even in the  
                      presence of changed page bitmap data  
  --close-files       do not keep files opened. Use at your own risk.  
  --core-file         Write core on fatal signals  
  --copy-back         Copy all the files in a previously made backup from the  
                      backup directory to their original locations.  
  --move-back         Move all the files in a previously made backup from the  
                      backup directory to the actual datadir location. Use with  
                      caution, as it removes backup files.  
  --galera-info       This options creates the xtrabackup\_galera\_info file  
                      which contains the local node state at the time of the  
                      backup. Option should be used when performing the backup  
                      of Percona-XtraDB-Cluster. Has no effect when backup  
                      locks are used to create the backup.  
  --slave-info        This option is useful when backing up a replication slave  
                      server. It prints the binary log position and name of the  
                      master server. It also writes this information to the  
                      "xtrabackup\_slave\_info" file as a "CHANGE MASTER"  
                      command. A new slave for this master can be set up by  
                      starting a slave server on this backup and issuing a  
                      "CHANGE MASTER" command with the binary log position  
                      saved in the "xtrabackup\_slave\_info" file.  
  --no-lock           Use this option to disable table lock with "FLUSH TABLES  
                      WITH READ LOCK". Use it only if ALL your tables are  
                      InnoDB and you DO NOT CARE about the binary log position  
                      of the backup. This option shouldn't be used if there are  
                      any DDL statements being executed or if any updates are  
                      happening on non-InnoDB tables (this includes the system  
                      MyISAM tables in the mysql database), otherwise it could  
                      lead to an inconsistent backup. If you are considering to  
                      use --no-lock because your backups are failing to acquire  
                      the lock, this could be because of incoming replication  
                      events preventing the lock from succeeding. Please try  
                      using --safe-slave-backup to momentarily stop the  
                      replication slave thread, this may help the backup to  
                      succeed and you then don't need to resort to using this  
                      option.  
  --lock-ddl          Issue LOCK TABLES FOR BACKUP if it is supported by server  
                      at the beginning of the backup to block all DDL  
                      operations.  
  --lock-ddl-timeout=\#  
                      If LOCK TABLES FOR BACKUP does not return within given  
                      timeout, abort the backup.  
  --lock-ddl-per-table  
                      Lock DDL for each table before xtrabackup starts to copy  
                      it and until the backup is completed.  
  --safe-slave-backup Stop slave SQL thread and wait to start backup until  
                      Slave\_open\_temp\_tables in "SHOW STATUS" is zero. If there  
                      are no open temporary tables, the backup will take place,  
                      otherwise the SQL thread will be started and stopped  
                      until there are no open temporary tables. The backup will  
                      fail if Slave\_open\_temp\_tables does not become zero after  
                      --safe-slave-backup-timeout seconds. The slave SQL thread  
                      will be restarted when the backup finishes.  
  --rsync             Uses the rsync utility to optimize local file transfers.  
                      When this option is specified, innobackupex uses rsync to  
                      copy all non-InnoDB files instead of spawning a separate  
                      cp for each file, which can be much faster for servers  
                      with a large number of databases or tables.  This option  
                      cannot be used together with --stream.  
  --force-non-empty-directories  
                      This option, when specified, makes --copy-back or  
                      --move-back transfer files to non-empty directories. Note  
                      that no existing files will be overwritten. If  
                      --copy-back or --nove-back has to copy a file from the  
                      backup directory which already exists in the destination  
                      directory, it will still fail with an error.  
  --no-version-check  This option disables the version check which is enabled  
                      by the --version-check option.  
  --tables-compatibility-check  
                      This option enables engine compatibility warning.  
                      (Defaults to on; use --skip-tables-compatibility-check to disable.)  
  --no-backup-locks   This option controls if backup locks should be used  
                      instead of FLUSH TABLES WITH READ LOCK on the backup  
                      stage. The option has no effect when backup locks are not  
                      supported by the server. This option is enabled by  
                      default, disable with --no-backup-locks.  
  --decompress        Decompresses all files with the .qp extension in a backup  
                      previously made with the --compress option.  
  -u, --user=name     This option specifies the MySQL username used when  
                      connecting to the server, if that's not the current user.  
                      The option accepts a string argument. See mysql --help  
                      for details.  
  -H, --host=name     This option specifies the host to use when connecting to  
                      the database server with TCP/IP.  The option accepts a  
                      string argument. See mysql --help for details.  
  -P, --port=\#        This option specifies the port to use when connecting to  
                      the database server with TCP/IP.  The option accepts a  
                      string argument. See mysql --help for details.  
  -p, --password\[=name\]  
                      This option specifies the password to use when connecting  
                      to the database. It accepts a string argument.  See mysql  
                      --help for details.  
  -S, --socket=name   This option specifies the socket to use when connecting  
                      to the local database server with a UNIX domain socket.  
                      The option accepts a string argument. See mysql --help  
                      for details.  
  --incremental-history-name=name  
                      This option specifies the name of the backup series  
                      stored in the PERCONA\_SCHEMA.xtrabackup\_history history  
                      record to base an incremental backup on. Xtrabackup will  
                      search the history table looking for the most recent  
                      (highest innodb\_to\_lsn), successful backup in the series  
                      and take the to\_lsn value to use as the starting lsn for  
                      the incremental backup. This will be mutually exclusive  
                      with --incremental-history-uuid, --incremental-basedir  
                      and --incremental-lsn. If no valid lsn can be found (no  
                      series by that name, no successful backups by that name)  
                      xtrabackup will return with an error. It is used with the  
                      --incremental option.  
  --incremental-history-uuid=name  
                      This option specifies the UUID of the specific history  
                      record stored in the PERCONA\_SCHEMA.xtrabackup\_history to  
                      base an incremental backup on.  
                      --incremental-history-name, --incremental-basedir and  
                      --incremental-lsn. If no valid lsn can be found (no  
                      success record with that uuid) xtrabackup will return  
                      with an error. It is used with the --incremental option.  
  --decrypt=name      Decrypts all files with the .xbcrypt extension in a  
                      backup previously made with --encrypt option.  
  --remove-original   Remove .qp and .xbcrypt files after decryption and  
                      decompression.  
  --ftwrl-wait-query-type=name  
                      This option specifies which types of queries are allowed  
                      to complete before innobackupex will issue the global  
                      lock. Default is all.  
  --kill-long-query-type=name  
                      This option specifies which types of queries should be  
                      killed to unblock the global lock. Default is "all".  
  --history\[=name\]    This option enables the tracking of backup history in the  
                      PERCONA\_SCHEMA.xtrabackup\_history table. An optional  
                      history series name may be specified that will be placed  
                      with the history record for the current backup being  
                      taken.  
  --kill-long-queries-timeout=\#  
                      This option specifies the number of seconds innobackupex  
                      waits between starting FLUSH TABLES WITH READ LOCK and  
                      killing those queries that block it. Default is 0  
                      seconds, which means innobackupex will not attempt to  
                      kill any queries.  
  --ftwrl-wait-timeout=\#  
                      This option specifies time in seconds that innobackupex  
                      should wait for queries that would block FTWRL before  
                      running it. If there are still such queries when the  
                      timeout expires, innobackupex terminates with an error.  
                      Default is 0, in which case innobackupex does not wait  
                      for queries to complete and starts FTWRL immediately.  
  --ftwrl-wait-threshold=\#  
                      This option specifies the query run time threshold which  
                      is used by innobackupex to detect long-running queries  
                      with a non-zero value of --ftwrl-wait-timeout. FTWRL is  
                      not started until such long-running queries exist. This  
                      option has no effect if --ftwrl-wait-timeout is 0.  
                      Default value is 60 seconds.  
  --debug-sleep-before-unlock=\#  
                      This is a debug-only option used by the XtraBackup test  
                      suite.  
  --safe-slave-backup-timeout=\#  
                      How many seconds --safe-slave-backup should wait for  
                      Slave\_open\_temp\_tables to become zero. (default 300)  
  --binlog-info\[=name\]  
                      This option controls how XtraBackup should retrieve  
                      server's binary log coordinates corresponding to the  
                      backup. Possible values are OFF, ON, LOCKLESS and AUTO.  
                      See the XtraBackup manual for more information  
  --reencrypt-for-server-id=\#  
                      Re-encrypt tablespace keys for given server-id.  
  --check-privileges  Check database user privileges before performing any  
                      query.  
  --read-buffer-size\[=\#\]  
                      Set datafile read buffer size, given value is scaled up  
                      to page size. Default is 10Mb.  
  --ssl-mode=name     SSL connection mode.  
  --ssl               Deprecated. Use --ssl-mode instead.  
                      (Defaults to on; use --skip-ssl to disable.)  
  --ssl-verify-server-cert  
                      Deprecated. Use --ssl-mode=VERIFY\_IDENTITY instead.  
  --ssl-ca=name       CA file in PEM format.

                      File path to the server public RSA key in PEM format.  
  -h, --datadir=name  Path to the database root.  
  -t, --tmpdir=name   Path for temporary files. Several paths may be specified,
