MySQL 多实例配置管理

配置多实例my.cnf：

[root@open_source 3309]# cat /mysql/3307/my.cnf [mysqld]user=mysqlbasedir=/usr/local/mysqldatadir=/mysql/3307/datasocket=/tmp/mysql3307.sockport=3307server_id=7[root@open_source 3309]# cat /mysql/3308/my.cnf [mysqld]user=mysqlbasedir=/usr/local/mysqldatadir=/mysql/3308/datasocket=/tmp/mysql3308.sockport=3308server_id=8[root@open_source 3309]# cat /mysql/3309/my.cnf [mysqld]user=mysqlbasedir=/usr/local/mysqldatadir=/mysql/3309/datasocket=/tmp/mysql3309.sockport=3309server_id=9

初始化多实例

mysqld --initialize-insecure --user=mysql --basedir=/usr/local/mysql --datadir=/mysql/3307/data/mysqld --initialize-insecure --user=mysql --basedir=/usr/local/mysql --datadir=/mysql/3308/data/mysqld --initialize-insecure --user=mysql --basedir=/usr/local/mysql --datadir=/mysql/3309/data/

启动多实例：

[root@open_source 3309]# mysqld_safe  --defaults-file=/mysql/3307/my.cnf &[root@open_source 3309]# mysqld_safe  --defaults-file=/mysql/3308/my.cnf &[root@open_source 3309]# mysqld_safe  --defaults-file=/mysql/3309/my.cnf &[root@open_source 3309]# ps -ef|grep mysql |grep -v greproot      10251   7511  0 18:57 pts/1    00:00:00 /bin/sh /usr/local/mysql/bin/mysqld_safe --defaults-file=/mysql/3307/my.cnfmysql     10428  10251  0 18:57 pts/1    00:00:00 /usr/local/mysql/bin/mysqld --defaults-file=/mysql/3307/my.cnf --basedir=/usr/local/mysql --datadir=/mysql/3307/data --plugin-dir=/usr/local/mysql/lib/plugin --user=mysql --log-error=open_source.err --pid-file=open_source.pid --socket=/tmp/mysql3307.sock --port=3307root      10464   7511  0 18:59 pts/1    00:00:00 /bin/sh /usr/local/mysql/bin/mysqld_safe --defaults-file=/mysql/3308/my.cnfmysql     10641  10464  0 18:59 pts/1    00:00:01 /usr/local/mysql/bin/mysqld --defaults-file=/mysql/3308/my.cnf --basedir=/usr/local/mysql --datadir=/mysql/3308/data --plugin-dir=/usr/local/mysql/lib/plugin --user=mysql --log-error=open_source.err --pid-file=open_source.pid --socket=/tmp/mysql3308.sock --port=3308root      10672   7511  0 19:00 pts/1    00:00:00 /bin/sh /usr/local/mysql/bin/mysqld_safe --defaults-file=/mysql/3309/my.cnfmysql     10849  10672  0 19:00 pts/1    00:00:01 /usr/local/mysql/bin/mysqld --defaults-file=/mysql/3309/my.cnf --basedir=/usr/local/mysql --datadir=/mysql/3309/data --plugin-dir=/usr/local/mysql/lib/plugin --user=mysql --log-error=open_source.err --pid-file=open_source.pid --socket=/tmp/mysql3309.sock --port=3309[root@open_source 3309]# netstat -anlt |grep 33tcp6       0      0 :::3307                 :::*                    LISTEN     tcp6       0      0 :::3308                 :::*                    LISTEN     tcp6       0      0 :::3309                 :::*                    LISTEN

登录多实例server_id：

[root@open_source 3309]# mysql -S /tmp/mysql3307.sock -e "select @@server_id"+-------------+| @@server_id |+-------------+|           7 |+-------------+[root@open_source 3309]# mysql -S /tmp/mysql3308.sock -e "select @@server_id"+-------------+| @@server_id |+-------------+|           8 |+-------------+[root@open_source 3309]# mysql -S /tmp/mysql3309.sock -e "select @@server_id"+-------------+| @@server_id |+-------------+|           9 |+-------------+

停止多实例:

[root@open_source ~]# mysqladmin -S /tmp/mysql3307.sock shutdown2020-03-10T00:04:36.491980Z mysqld_safe mysqld from pid file /mysql/3307/data/open_source.pid ended[1]   Done                    mysqld_safe --defaults-file=/mysql/3307/my.cnf  (wd: /mysql/3309)(wd now: ~)[root@open_source ~]# mysqladmin -S /tmp/mysql3308.sock shutdown2020-03-10T00:04:45.304744Z mysqld_safe mysqld from pid file /mysql/3308/data/open_source.pid ended[2]-  Done                    mysqld_safe --defaults-file=/mysql/3308/my.cnf  (wd: /mysql/3309)(wd now: ~)[root@open_source ~]# mysqladmin -S /tmp/mysql3309.sock shutdown2020-03-10T00:04:54.383289Z mysqld_safe mysqld from pid file /mysql/3309/data/open_source.pid ended[3]+  Done                    mysqld_safe --defaults-file=/mysql/3309/my.cnf  (wd: /mysql/3309)(wd now: ~)
