mysql源码安装
检查是否安装了MySQL
root@bd-qa-mongodb-85:~#rpm -qa | grep -i mysql
mysql-libs-5.1.73-5.el6_6.x86_64
使用yum来删除MySQL
root@bd-qa-mongodb-85:~#yum -y remove mysql-libs
安装依赖包
root@bd-qa-mongodb-85:~#yum -y install gcc gcc-c++ ncurses ncurses-devel cmake
下载相应源码包
wget http://downloads.sourceforge.net/project/boost/boost/1.59.0/boost\_1\_59\_0.tar.gz
wget http://dev.mysql.com/get/Downloads/MySQL-5.7/mysql-5.7.9.tar.gz
添加mysql用户
useradd -M -s /sbin/nologin mysql
解压
tar xzf boost_1_59_0.tar.gz
tar xzf mysql-5.7.9.tar.gz
创建文件夹
mkdir -p /data/mysql
cd mysql-5.7.9
预编译
首先cmake参数的一些解释
-DCMAKE_INSTALL_PREFIX= 安装根目录
-DSYSCONFDIR=配置文件(my.cnf)目录
-DCMAKE_INSTALL_PREFIX= unix套接字目录
-DDEFAULT_CHARSET= 默认字符集
-DDEFAULT_COLLATION=默认编码
-DWITH_EXTRA_CHARSETS= 额外的编码，请使用ALL来编译。
-DWITH_MYISAM_STORAGE_ENGINE=1 编译myisam存储引擎，默认的存储引擎，不加也可以
-DWITH_INNOBASE_STORAGE_ENGINE=1 支持InnoDB存储引擎，这个也是默认安装的
-DWITH_READLINE=1 使用readline功能
-DENABLED_LOCAL_INFILE=1 可以使用load data infile命令从本地导入文件
-DMYSQL_DATADIR=数据库 数据目录
cmake . -DCMAKE_INSTALL_PREFIX=/usr/local/mysql -DMYSQL_DATADIR=/data/mysql -DDOWNLOAD_BOOST=1 -DWITH_BOOST=../boost_1_59_0 -DSYSCONFDIR=/etc -DWITH_INNOBASE_STORAGE_ENGINE=1 -DWITH_PARTITION_STORAGE_ENGINE=1 -DWITH_FEDERATED_STORAGE_ENGINE=1 -DWITH_BLACKHOLE_STORAGE_ENGINE=1 -DWITH_MYISAM_STORAGE_ENGINE=1 -DENABLED_LOCAL_INFILE=1 -DENABLE_DTRACE=0 -DDEFAULT_CHARSET=utf8mb4 -DDEFAULT_COLLATION=utf8mb4_general_ci -DWITH_EMBEDDED_SERVER=1
注意：#从MySQL 5.7.5开始Boost库是必需的
编译安装
root@bd-qa-mongodb-85:/opt/app/mysql/mysql-5.7.9# make -j `grep processor /proc/cpuinfo | wc -l` #编译很消耗系统资源，小内存可能编译通不过
root@bd-qa-mongodb-85:/opt/app/mysql/mysql-5.7.9# make install
三个节点均执行上述操作
启动脚本，设置开机自启动
cp /usr/local/mysql/support-files/mysql.server /etc/init.d/mysqld
chmod +x /etc/init.d/mysqld
chkconfig —add mysqld
chkconfig mysqld on

初始化数据库
/usr/local/mysql/bin/mysqld —initialize-insecure —user=mysql —basedir=/usr/local/mysql —datadir=/data/mysql
注：
之前版本mysql_install_db是在mysql_basedir/script下，5.7放在了mysql_install_db/bin目录下,且已被废弃
“–initialize”会生成一个随机密码(~/.mysql_secret)，而”–initialize-insecure”不会生成密码
–datadir目标目录下不能有数据文件
启动数据库
root@bd-qa-mongodb-85:~#service mysqld start
Starting MySQL. SUCCESS!
//添加path路径： vim /etc/profile 添加下面2行 在文件的结尾
[root@oracle mysql-5.7.9]# export MYSQL_HOME=/usr/local/mysql
[root@oracle mysql-5.7.9]# export PATH=$PATH:$MYSQL_HOME/bin
//修改root密码，和授权新用户：
mysql> set password=password(‘fafa123’);
Query OK, 0 rows affected, 1 warning (0.00 sec)
mysql> grant all on *.* to dba_user@’%’ identified by ‘fafa123’;
Query OK, 0 rows affected, 1 warning (0.00 sec)
mysql> flush privileges;

卸载数据库，注意删除的时候，直接删除目录就行
