多实例mysql的安装和管理

mysql的多实例有两种方式可以实现，两种方式各有利弊。
第一种是使用多个配置文件启动不同的进程来实现多实例，这种方式的优势逻辑简单，配置简单，缺点是管理起来不太方便。
第二种是通过官方自带的mysqld_multi使用单独的配置文件来实现多实例，这种方式定制每个实例的配置不太方面，优点是管理起来很方便，集中管理。

下面就分别来实战这两种多实例的安装和管理

先来学习第一种使用多个配置文件启动多个不同进程的情况：

环境介绍：

mysql 版本：5.1.50

操作系统：SUSE 11

mysql实例数：3个

实例占用端口分别为：3306、3307、3308

创建mysql用户

    点击(此处)折叠或打开

  • /data/dbdata_3306/mysqld start
  • /data/dbdata_3307/mysqld start
  • /data/dbdata_3308/mysqld start

    • 更改原来密码（处于安全考虑，还需要删除系统中没有密码的帐号，这里省略了）：
     

    点击(此处)折叠或打开

  • /usr/local/mysql/bin/mysqladmin -uroot password 'password' -S /data/dbdata_3306/mysql.sock
  • /usr/local/mysql/bin/mysqladmin -uroot password 'password' -S /data/dbdata_3307/mysql.sock
  • /usr/local/mysql/bin/mysqladmin -uroot password 'password' -S /data/dbdata_3308/mysql.sock
    • 登录测试并创建关闭mysql的帐号权限，mysqld脚本要用到！
     

    点击(此处)折叠或打开

  • /usr/local/mysql/bin/mysql -uroot -ppassword -S /data/dbdata_3308/mysql.sock
  • GRANT SHUTDOWN ON *.* TO 'admin'@'localhost' IDENTIFIED BY 'password';
  • flush privileges;
  • /usr/local/mysql/bin/mysql -uroot -ppassword -S /data/dbdata_3308/mysql.sock
  • GRANT SHUTDOWN ON *.* TO 'admin'@'localhost' IDENTIFIED BY 'password';
  • flush privileges;
  • /usr/local/mysql/bin/mysql -uroot -ppassword -S /data/dbdata_3308/mysql.sock
  • GRANT SHUTDOWN ON *.* TO 'admin'@'localhost' IDENTIFIED BY 'password';
  • flush privileges;
    • 创建了admin帐号以后脚本的stop功能和restart功能就正常了！
    更改环境变量
     

    点击(此处)折叠或打开

  • vim /etc/profile 添加下面一行内容
  • PATH=${PATH}:/usr/local/mysql/bin/
  • source /etc/profile
    • 添加到自动启动
     

    点击(此处)折叠或打开

  • vim /etc/init.d/boot.local
  • /data/dbdata_3306/mysqld start
  • /data/dbdata_3307/mysqld start
  • /data/dbdata_3308/mysqld start
    • 如果是rhel或者centos系统的话自启动文件/etc/rc.local
     
    管理的话，在本地都是采用 -S /data/dbdata_3308/mysql.sock，如果在远程可以通过不同的端口连接上去坐管理操作。其他的和单实例的管理没什么区别！
     
     
     
    再来看第二种通过官方自带的mysqld_multi来实现多实例实战：
    这里的mysql安装以及数据库的初始化和前面的步骤一样，就不再赘述。

    管理的话，在本地都是采用 -S /data/dbdata_3308/mysql.sock，如果在远程可以通过不同的端口连接上去坐管理操作。其他的和单实例的管理没什么区别！
    大家在管理多实例的话可以使用mysqlmanager实例管理器，管理器来会比较方面，限于篇幅，这里就不在多做介绍！
