一.安装mysql
略
二.配置my.cnf
[mysqld3306] port=3306 datadir=/var/lib/mysql socket=/var/lib/mysql/mysql3306.sock pid-file=/var/run/mysqld/mysqld3306.pid log-error = /var/lib/mysql/error.log # Disabling symbolic-links is recommended to prevent assorted security risks symbolic-links=0 # Recommended in standard MySQL setup sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES [mysqld3307] port=3307 datadir=/var/lib/mysql3307 socket=/var/lib/mysql3307/mysql3307.sock pid-file=/var/run/mysqld/mysqld3307.pid log-error = /var/lib/mysql3307/error.log # Disabling symbolic-links is recommended to prevent assorted security risks symbolic-links=0 # Recommended in standard MySQL setup sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES [mysqld3308] port=3308 datadir=/var/lib/mysql3308 socket=/var/lib/mysql3308/mysql3308.sock pid-file=/var/run/mysqld/mysqld3308.pid log-error = /var/lib/mysql3308/error.log # Disabling symbolic-links is recommended to prevent assorted security risks symbolic-links=0 # Recommended in standard MySQL setup sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES [mysqld_multi] mysqld = /usr/bin/mysqld_safe mysqladmin = /usr/bin/mysqladmin [mysqld_safe] log-error=/var/log/mysqld.log pid-file=/var/run/mysqld/mysqld.pid
三.创建和初始化数据目录
1.在/var/lib下创建mysql3307和mysql3308
2.赋予权限
chown mysql:mysql /var/lib/mysql3307 .....
3.初始化:
... mysql_install_db --basedir=/usr/local/mysql/ --datadir=/var/lib/mysql3307 --defaults-file=/etc/my.cnf ...
四.多实例管理
启动全部实例：/usr/local/mysql/bin/mysqld_multi start
查看全部实例状态：/usr/local/mysql/bin/mysqld_multi report
启动单个实例：/usr/local/mysql/bin/mysqld_multi start 3306
停止单个实例：/usr/local/mysql/bin/mysqld_multi stop 3306
查看单个实例状态：/usr/local/mysql/bin/mysqld_multi report 3306
