生产环境安装5.7.23全过程

先执行initialization.sh优化脚本 详情见 [Linux][]

在安装mysql前，需要先查看一下是否清空了系统自带了mysql  
我们这里需要删除系统自带了mysql lib

我们先把mysql放置在/opt下  
先上传与线上版本一致的

[root@prd3-mysql01-180 opt]# cat /etc/redhat-release 
    CentOS release 6.5 (Final)

[root@prd3-mysql-0-36 opt]# ll
    total 629320
    -rw-r--r--  1 root root      7214 Mar 27 17:37 initialization.sh
    -rw-r--r--  1 root root 644399365 Oct 13  2018 mysql-5.7.23-linux-glibc2.12-x86_64.tar.gz
    drwxr-xr-x. 2 root root      4096 Nov 22  2013 rh
    drwxr-xr-x  2 root root      4096 Apr 23 16:34 scripts

第一步：删除过期系统自带的lib

[root@prd3-mysql-0-36 opt]# rpm -qa|grep mysql
    mysql-libs-5.1.71-1.el6.x86_64
    [root@prd3-mysql-0-36 opt]# find / -name "mysql"
    /usr/share/mysql
    /usr/lib64/mysql
    [root@prd3-mysql-0-36 opt]# rpm -e --nodeps mysql-libs-5.1.71-1.el6.x86_64
    [root@prd3-mysql-0-36 opt]# rpm -qa|grep mysql                            
    [root@prd3-mysql-0-36 opt]# find / -name "mysql"

补充安装相关的依赖  //要做，防止后面出错
    [root@ct6 ~]# yum -y install perl-Module-Install.noarch
    [root@ct6 ~]# rpm -qa|grep 'perl-Module-Install'       
    perl-Module-Install-0.91-4.el6.noarch

第二步创建mysql的用户

[root@prd3-mysql-0-36 opt]# groupadd mysql
    [root@prd3-mysql-0-36 opt]# useradd -r -g mysql -s /bin/false mysql

第三步创建mysql的数据目录  
`[root@prd3-mysql-0-36 opt]# mkdir -p /ivargo/data/mysql`

第三步：解压 mysql安装包到/usr/local 下

[root@prd3-mysql-0-36 opt]# tar -zxvf mysql-5.7.23-linux-glibc2.12-x86_64.tar.gz -C /usr/local/
    ...
    ...
    ...
    
    [root@prd3-mysql-0-36 opt]# cd /usr/local/
    [root@prd3-mysql-0-36 local]# ll
    total 44
    drwxr-xr-x. 2 root root 4096 Sep 23  2011 bin
    drwxr-xr-x. 2 root root 4096 Sep 23  2011 etc
    drwxr-xr-x. 2 root root 4096 Sep 23  2011 games
    drwxr-xr-x. 2 root root 4096 Sep 23  2011 include
    drwxr-xr-x. 2 root root 4096 Sep 23  2011 lib
    drwxr-xr-x. 2 root root 4096 Sep 23  2011 lib64
    drwxr-xr-x. 2 root root 4096 Sep 23  2011 libexec
    drwxr-xr-x  9 root root 4096 Apr 23 17:12 mysql-5.7.23-linux-glibc2.12-x86_64
    drwxr-xr-x. 2 root root 4096 Sep 23  2011 sbin
    drwxr-xr-x. 5 root root 4096 Apr 16  2018 share
    drwxr-xr-x. 2 root root 4096 Sep 23  2011 src
    到这来有2个方式，方式是  //一个是直接mv 一个是用ln -s 软连接
    
    在这里我们实现和生产上一样的，用mv

第四步：创建/usr/local/mysql
    [root@prd3-mysql-0-36 local]# mkdir mysql
    [root@prd3-mysql-0-36 local]# ll
    total 48
    drwxr-xr-x. 2 root root 4096 Sep 23  2011 bin
    drwxr-xr-x. 2 root root 4096 Sep 23  2011 etc
    drwxr-xr-x. 2 root root 4096 Sep 23  2011 games
    drwxr-xr-x. 2 root root 4096 Sep 23  2011 include
    drwxr-xr-x. 2 root root 4096 Sep 23  2011 lib
    drwxr-xr-x. 2 root root 4096 Sep 23  2011 lib64
    drwxr-xr-x. 2 root root 4096 Sep 23  2011 libexec
    drwxr-xr-x  2 root root 4096 Apr 23 17:20 mysql
    drwxr-xr-x  9 root root 4096 Apr 23 17:12 mysql-5.7.23-linux-glibc2.12-x86_64
    drwxr-xr-x. 2 root root 4096 Sep 23  2011 sbin
    drwxr-xr-x. 5 root root 4096 Apr 16  2018 share
    drwxr-xr-x. 2 root root 4096 Sep 23  2011 src
    [root@prd3-mysql-0-36 local]# mv /usr/local/mysql-5.7.23-linux-glibc2.12-x86_64/* /usr/local/mysql
    [root@prd3-mysql-0-36 local]# rm -rf mysql-5.7.23-linux-glibc2.12-x86_64/
    [root@prd3-mysql-0-36 local]# ll
    total 44
    drwxr-xr-x. 2 root root 4096 Sep 23  2011 bin
    drwxr-xr-x. 2 root root 4096 Sep 23  2011 etc
    drwxr-xr-x. 2 root root 4096 Sep 23  2011 games
    drwxr-xr-x. 2 root root 4096 Sep 23  2011 include
    drwxr-xr-x. 2 root root 4096 Sep 23  2011 lib
    drwxr-xr-x. 2 root root 4096 Sep 23  2011 lib64
    drwxr-xr-x. 2 root root 4096 Sep 23  2011 libexec
    drwxr-xr-x  9 root root 4096 Apr 23 17:21 mysql
    drwxr-xr-x. 2 root root 4096 Sep 23  2011 sbin
    drwxr-xr-x. 5 root root 4096 Apr 16  2018 share
    drwxr-xr-x. 2 root root 4096 Sep 23  2011 src

第五步：设置/usr/local/mysql 的权限
    [root@prd3-mysql-0-36 local]# pwd
    /usr/local
    [root@prd3-mysql-0-36 local]# chown -R mysql:mysql mysql

第六步：修改mysql 配置文件
    [root@prd3-mysql-0-36 local]# pwd
    /usr/local
    [root@prd3-mysql-0-36 local]# ll
    total 44
    drwxr-xr-x. 2 root  root  4096 Sep 23  2011 bin
    drwxr-xr-x. 2 root  root  4096 Sep 23  2011 etc
    drwxr-xr-x. 2 root  root  4096 Sep 23  2011 games
    drwxr-xr-x. 2 root  root  4096 Sep 23  2011 include
    drwxr-xr-x. 2 root  root  4096 Sep 23  2011 lib
    drwxr-xr-x. 2 root  root  4096 Sep 23  2011 lib64
    drwxr-xr-x. 2 root  root  4096 Sep 23  2011 libexec
    drwxr-xr-x  9 mysql mysql 4096 Apr 23 17:21 mysql
    drwxr-xr-x. 2 root  root  4096 Sep 23  2011 sbin
    drwxr-xr-x. 5 root  root  4096 Apr 16  2018 share
    drwxr-xr-x. 2 root  root  4096 Sep 23  2011 src
    [root@prd3-mysql-0-36 local]# cd mysql/
    [root@prd3-mysql-0-36 mysql]# ll
    total 52
    drwxr-xr-x  2 mysql mysql  4096 Apr 23 17:12 bin
    -rw-r--r--  1 mysql mysql 17987 Jun  8  2018 COPYING
    drwxr-xr-x  2 mysql mysql  4096 Apr 23 17:13 docs
    drwxr-xr-x  3 mysql mysql  4096 Apr 23 17:11 include
    drwxr-xr-x  5 mysql mysql  4096 Apr 23 17:12 lib
    drwxr-xr-x  4 mysql mysql  4096 Apr 23 17:12 man
    -rw-r--r--  1 mysql mysql  2478 Jun  8  2018 README
    drwxr-xr-x 28 mysql mysql  4096 Apr 23 17:12 share
    drwxr-xr-x  2 mysql mysql  4096 Apr 23 17:12 support-files
    [root@prd3-mysql-0-36 mysql]# cd support-files/
    [root@prd3-mysql-0-36 support-files]# ll
    total 24
    -rw-r--r-- 1 mysql mysql   773 Jun  8  2018 magic
    -rwxr-xr-x 1 mysql mysql  1061 Jun  8  2018 mysqld_multi.server
    -rwxr-xr-x 1 mysql mysql   894 Jun  8  2018 mysql-log-rotate
    -rwxr-xr-x 1 mysql mysql 10576 Jun  8  2018 mysql.server
    [root@prd3-mysql-0-36 support-files]# cp mysql.server /etc/init.d/mysql
    然后修改/etc/init.d/mysql的参数，
    vim /etc/init.d/mysql
    修改
    basedir=/usr/local/mysql
    datadir=/ivargo/data/mysql
    
    设置mysql启动的配置文件my.cnf  设置配置文件/etc/my.cnf
    [root@prd3-mysql-0-36 support-files]# find / -name "my.cnf"
    [root@prd3-mysql-0-36 opt]# mv my.cnf /etc/
    [root@prd3-mysql-0-36 opt]# ls -l /etc/my.cnf 
    -rw-r--r-- 1 root root 1649 Oct 11  2018 /etc/my.cnf

第七步：初始化mysql
    [root@prd3-mysql-0-36 bin]# pwd
    /usr/local/mysql/bin
    初始化命令
    ./mysqld --defaults-file=/etc/my.cnf --initialize --user=mysql --basedir=/usr/local/mysql --datadir=/ivargo/data/mysql
    [root@prd3-mysql-0-36 bin]# ./mysqld --defaults-file=/etc/my.cnf --initialize --user=mysql --basedir=/usr/local/mysql --datadir=/ivargo/data/mysql
    ...
    ...
    ...

第八步 ：启动mysql 并设置 开机自启动 chkconfig mysql on
    [root@prd3-mysql-0-36 bin]# service mysql start
    Starting MySQL.. SUCCESS! 
    [root@prd3-mysql-0-36 bin]# netstat -lntup
    Active Internet connections (only servers)
    Proto Recv-Q Send-Q Local Address               Foreign Address             State       PID/Program name   
    tcp        0      0 0.0.0.0:22                  0.0.0.0:*                   LISTEN      1531/sshd           
    tcp        0      0 127.0.0.1:25                0.0.0.0:*                   LISTEN      1607/master         
    tcp        0      0 :::22                       :::*                        LISTEN      1531/sshd           
    tcp        0      0 ::1:25                      :::*                        LISTEN      1607/master         
    tcp        0      0 :::3306                     :::*                        LISTEN      4567/mysqld

第九步 ：重新设置mysql密码

[root@prd3-mysql-0-36 bin]# ./mysql -uroot -p
    Enter password: 
    Welcome to the MySQL monitor.  Commands end with ; or \g.
    Your MySQL connection id is 2
    Server version: 5.7.23-log

    Oracle is a registered trademark of Oracle Corporation and/or its

    owners.
    
    Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.
    
    @(none)> SET PASSWORD FOR 'root'@'localhost'=PASSWORD('xxx');
    Query OK, 0 rows affected, 1 warning (0.01 sec)
    @(none)> flush privileges;
    Query OK, 0 rows affected (0.00 sec)

第十步：设置mysql的环境变量  
我这里用的 自己的方法

echo 'export PATH=/usr/local/mysql/bin:$PATH' >> /etc/profile
    tail -1 /etc/profile
    source /etc/profile
    [root@prd3-mysql-0-36 opt]# which mysql
    /usr/local/mysql/bin/mysql

第十一步：优化mysql

需要给生产上root % 权限

GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY 'XXX' WITH GRANT OPTION; 
    @(none)> GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY 'XXX' WITH GRANT OPTION; 
    Query OK, 0 rows affected, 1 warning (0.01 sec)
    
    @(none)> flush privileges;
    Query OK, 0 rows affected (0.00 sec)
    
    @(none)> select user,host from mysql.user;
    +---------------+-----------+
    | user          | host      |
    +---------------+-----------+
    | root          | %         |
    | mysql.session | localhost |
    | mysql.sys     | localhost |
    | root          | localhost |
    +---------------+-----------+
    4 rows in set (0.00 sec)
