一台服务器启动多个mysql实例

1、安装mysql    软件下载地址：http://www.percona.com/ 安装依赖库：yum install cmake bison ncurses-devel gcc-c++ #rpm -ivh --nodeps --force Percona-Server-55-debuginfo-5.5.24-rel26.0.256.rhel6.x86_64.rpm                                   Percona-Server-server-55-5.5.24-rel26.0.256.rhel6.x86_64.rpm                            Percona-Server-client-55-5.5.24-rel26.0.256.rhel6.x86_64.rpm                                     Percona-Server-shared-55-5.5.24-rel26.0.256.rhel6.x86_64.rpm                         Percona-Server-devel-55-5.5.24-rel26.0.256.rhel6.x86_64.rpm    忽略报错

2、创建mysql目录        实例1：/home/mysql   启动3306端口        #mkdir -p /home/mysql/{data,logs}    #chown mysql:mysql /home/mysql/ -R      实例2：/usr/local/mysql启动3307端口    #mkdir -p /usr/local/mysql/{data,logs，etc，var}    #chown mysql:mysql /usr/local/mysql/ -R 3、修改实例2的配置文件    #vi /user/local/mysql/etc/my.cnf    [client]    port            = 3307    socket          = /usr/local/mysql/var/mysql.sock    [mysqld]    port            = 3307    socket          = /var/lib/mysql/mysql-3307.sock    datadir         = /usr/local/mysql/data    log_error       = /usr/local/mysql/logs/db_error.log 4、安装mysql数据库系统表 #/usr/bin/mysql_install_db  --defaults-file=/etc/my.cnf  --basedir=/usr/  --datadir=/home/mysql/data  --user=mysql   #/usr/bin/mysql_install_db  --defaults-file=/usr/local/mysql/etc/my.cnf  --basedir=/usr/  --datadir=/usr/local/mysql/data  --user=mysql

5、启动数据库     /usr/bin/mysqld_safe  --defaults-file=/etc/my.cnf &     /usr/bin/mysqld_safe  --defaults-file=/usr/local/mysql/etc/my.cnf &
