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

  1. /usr/sbin/groupadd mysql
  2. /usr/sbin/useradd -g mysql mysql
编译安装mysql

点击(此处)折叠或打开

  1. tar xzvf mysql-5.1.50.tar.gz
  2. cd mysql-5.1.50
  3. ./configure ‘--prefix=/usr/local/mysql‘ ‘--with-charset=utf8‘ ‘--with-extra-charsets=complex‘ ‘--with-pthread‘ ‘--enable-thread-safe-client‘ ‘--with-ssl‘ ‘--with-client-ldflags=-all-static‘ ‘--with-mysqld-ldflags=-all-static‘ ‘--with-plugins=partition,innobase,blackhole,myisam,innodb_plugin,heap,archive‘ ‘--enable-shared‘ ‘--enable-assembler‘
  4. make
  5. make install
初始化数据库

点击(此处)折叠或打开

  1. /usr/local/mysql/bin/mysql_install_db --basedir=/usr/local/mysql --datadir=/data/dbdata_3306 --user=mysql
  2. /usr/local/mysql/bin/mysql_install_db --basedir=/usr/local/mysql --datadir=/data/dbdata_3307 --user=mysql
  3. /usr/local/mysql/bin/mysql_install_db --basedir=/usr/local/mysql --datadir=/data/dbdata_3308 --user=mysql
创建配置文件
vim /data/dbdata_3306/my.cnf
3306的配置文件如下：

启动3306、3307、3308的mysql

点击(此处)折叠或打开

  1. /data/dbdata_3306/mysqld start
  2. /data/dbdata_3307/mysqld start
  3. /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

  1. /usr/local/mysql/bin/mysqladmin -uroot password ‘password‘ -S /data/dbdata_3306/mysql.sock
  2. /usr/local/mysql/bin/mysqladmin -uroot password ‘password‘ -S /data/dbdata_3307/mysql.sock
  3. /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

  1. /usr/local/mysql/bin/mysql -uroot -ppassword -S /data/dbdata_3308/mysql.sock
  2. GRANT SHUTDOWN ON *.* TO ‘admin‘@‘localhost‘ IDENTIFIED BY ‘password‘;
  3. flush privileges;
  4. /usr/local/mysql/bin/mysql -uroot -ppassword -S /data/dbdata_3308/mysql.sock
  5. GRANT SHUTDOWN ON *.* TO ‘admin‘@‘localhost‘ IDENTIFIED BY ‘password‘;
  6. flush privileges;
  7. /usr/local/mysql/bin/mysql -uroot -ppassword -S /data/dbdata_3308/mysql.sock
  8. GRANT SHUTDOWN ON *.* TO ‘admin‘@‘localhost‘ IDENTIFIED BY ‘password‘;
  9. 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

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

点击(此处)折叠或打开

  1. vim /etc/init.d/boot.local
  2. /data/dbdata_3306/mysqld start
  3. /data/dbdata_3307/mysqld start
  4. /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：

mysqld_multi启动

点击(此处)折叠或打开

  1. /usr/local/mysql/bin/mysqld_multi start 1
  2. /usr/local/mysql/bin/mysqld_multi start 2
  3. /usr/local/mysql/bin/mysqld_multi start 3
或者采用一条命令的形式：

点击(此处)折叠或打开

  1. /usr/local/mysql/bin/mysqld_multi start 1-3
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

  1. /usr/local/mysql/bin/mysqladmin -uroot password ‘password‘ -S /data/dbdata_3306/mysql.sock
  2. /usr/local/mysql/bin/mysqladmin -uroot password ‘password‘ -S /data/dbdata_3307/mysql.sock
  3. /usr/local/mysql/bin/mysqladmin -uroot password ‘password‘ -S /data/dbdata_3308/mysql.sock
登录测试并创建admin密码(停止mysql的时候需要使用到)

点击(此处)折叠或打开

  1. /usr/local/mysql/bin/mysql -uroot -ppassword -S /data/dbdata_3308/mysql.sock
  2. GRANT SHUTDOWN ON *.* TO ‘admin‘@‘localhost‘ IDENTIFIED BY ‘password‘;
  3. flush privileges;
  4. /usr/local/mysql/bin/mysql -uroot -ppassword -S /data/dbdata_3308/mysql.sock
  5. GRANT SHUTDOWN ON *.* TO ‘admin‘@‘localhost‘ IDENTIFIED BY ‘password‘;
  6. flush privileges;
  7. /usr/local/mysql/bin/mysql -uroot -ppassword -S /data/dbdata_3308/mysql.sock
  8. GRANT SHUTDOWN ON *.* TO ‘admin‘@‘localhost‘ IDENTIFIED BY ‘password‘;
  9. flush privileges;
更改环境变量

点击(此处)折叠或打开

  1. vim /etc/profile
  2. PATH=${PATH}:/usr/local/mysql/bin/
  3. source /etc/profile
添加到自动启动

点击(此处)折叠或打开

  1. vim /etc/init.d/boot.local
  2. /usr/local/mysql/bin/mysqld_multi start 1-3
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！
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！
