创建mysql 用户和用户组
groupadd -g 701 mysql
useradd -g mysql -m mysql -d /home/mysql
mysql目录划分：
mysql软件目录: /mysql/installdir
mysql数据目录：/mysql/datadir/3306/data
mysql日志目录：/mysql/logdir/3306/{bin_log,general_log,error_log,query_log}
mkdir -p /mysql/installdir
mkdir -p /mysql/datadir/3306/data
mkdir -p /mysql/logdir/3306/bin_log
mkdir -p /mysql/logdir/3306/general_log
mkdir -p /mysql/logdir/3306/error_log
mkdir -p /mysql/logdir/3306/query_log
mkdir -p /mysql/installdir
mkdir -p /mysql/datadir/3307/data
mkdir -p /mysql/logdir/3307/bin_log
mkdir -p /mysql/logdir/3307/general_log
mkdir -p /mysql/logdir/3307/error_log
mkdir -p /mysql/logdir/3307/query_log
安装所需要的包：
yum install -y cmake gcc gcc-c++ ncurses-devel bison zlib libxml openssl
编译
cmake \
-DCMAKE_INSTALL_PREFIX=/mysql/installdir \
-DINSTALL_DATADIR=/mysql/datadir/3306/data \
-DDEFAULT_CHARSET=utf8 \
-DDEFAULT_COLLATION=utf8_general_ci \
-DEXTRA_CHARSETS=all \
-DWITH_SSL=yes \
-DWITH_EMBEDDED_SERVER=1 \
-DENABLED_LOCAL_INFILE=1 \
-DWITH_MYISAM_STORAGE_ENGINE=1 \
-DWITH_INNOBASE_STORAGE_ENGINE=1 \
-DWITH_ARCHIVE_STORAGE_ENGINE=1 \
-DWITH_BLACKHOLE_STORAGE_ENGINE=1 \
-DWITH_FEDERATED_STORAGE_ENGINE=1 \
-DWITH_PARTITION_STORAGE_ENGINE=1 \
-DMYSQL_UNIX_ADDR=/mysql/datadir/3306/data/mysql.sock \
-DMYSQL_TCP_PORT=3306 \
-DENABLED_LOCAL_INFILE=1 \
-DSYSCONFDIR=/etc \
-DWITH_READLINE=on
安装：
make && make install
实例初始化：
/mysql/installdir/scripts/mysql_install_db --basedir=/mysql/installdir/ --datadir=/mysql/datadir/3306/data --defaults-file=/mysql/datadir/3306/my.cnf
/mysql/installdir/scripts/mysql_install_db --basedir=/mysql/installdir/ --datadir=/mysql/datadir/3307/data --defaults-file=/mysql/datadir/3307/my.cnf
启用mysql实例
./mysqld_safe --defaults-file=/mysql/datadir/3306/my.cnf &
./mysqld_safe --defaults-file=/mysql/datadir/3307/my.cnf &
查看是否启动
ps -ef | grep mysql
修改密码：
use mysql;
UPDATE user SET Password = PASSWORD('admin123') WHERE user = 'root';
flush privileges;
多实例登录：
mysql -uroot -padmin123 -S /mysql/datadir/3306/data/mysql.sock
mysql -uroot -padmin123 -S /mysql/datadir/3307/data/mysql.sock
查看实例端口号：
mysql> show variables like 'port'
-> ;
+---------------+-------+
| Variable_name | Value |
+---------------+-------+
| port | 3307 |
+---------------+-------+
