一、mysql安装目录说明
mysql5.6以二进制安装包安装在/data/mysql56下
数据目录为/data/mysql56/data下
配置文件为/etc/my.cnf下
二、多实例目录说明
/mysql-instance
|-- 3308
|-- data #3308实例数据目录
|-- 3309
|-- data #3309实例数据目录
1 2 | >mkdir-p /mysql-instance/3308/data
>mkdir-p /mysql-instance/3309/data
|
三、复制配置文件到实例目录下
1 2 | > cp /data/mysql56/support-files/my-default.cnf /mysql-instance/3308/my.cnf
> cp /data/mysql56/support-files/my-default.cnf /mysql-instance/3309/my.cnf
|
四、修改配置文件
1 2 | > vi /mysql-instance/3308/my.cnf
> vi /mysql-instance/3309/my.cnf
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 | [client]
port = 3308
socket = /mysql-instance/3308/mysql.sock
[mysql]
no-auto-rehash
[mysqld]
user = mysql
port = 3308
socket = /mysql-instance/3308/mysql.sock
basedir = /data/mysql56
datadir = /mysql-instance/3308/data
pid-file = /mysql-instance/3308/mysql.pid
relay-log = /mysql-instance/3308/relay-bin
relay-log-info-file = /mysql-instance/3308/relay-log.info
server-id = 12
[mysqld_safe]
log-error = /mysql-instance/3308/mysql.err
pid-file = /mysql-instance/3308/mysql.pid
|
3309的配置同上，只需把3308的地方换成3309
五、创建mysql多实例启动文件
1 2 | > vi /mysql-instance/3308/mysql
> vi /mysql-instance/3309/mysql
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 | #!/bin/sh
port=3308
mysql_user="root"
#请填写自已数据库密码
mysql_pwd="123456"
cmd_path="/data/mysql56/bin"
mysql_sock="/mysql-instance/${port}/mysql.sock"
mysql_start() {
if[ ! -e"$mysql_sock"];then
printf"mysql start ... \n"
/bin/sh ${cmd_path}/mysqld_safe --defaults-file=/mysql-instance/${port}/my.cnf 2>&1 > /dev/null &
else
printf"mysql is running ... \n"
exit
fi
}
mysql_stop() {
if[ ! -e"$mysql_sock"];then
printf"mysql is stopped ... \n"
exit
else
printf"mysql stop ... \n"
${cmd_path}/mysqladmin -u ${mysql_user} -p${mysql_pwd} -S /mysql-instance/${port}/mysql.sock shutdown
fi
}
mysql_restart() {
printf"mysql restart ... \n"
mysql_stop
sleep 2
mysql_start
}
case$1in
start) mysql_start ;;
stop) mysql_stop ;;
restart) mysql_restart ;;
*)
printf"usage: /data/${port}/mysql {start|stop|restart}\n"
esac
|
六、授权mysql用户目录权限
1 2 3 | >chown-R mysql.mysql /mysql-instance
>chmod700 /mysql-instance/3308/mysql
>chmod700 /mysql-instance/3309/mysql
|
七、初始化mysql多实例数据库文件
1 2 3 | > cd /daa/mysql56/scripts
> ./mysql_install_db --basedir=/data/mysql56 --datadir=/mysql-instance/3308/data --user=mysql
> ./mysql_install_db --basedir=/data/mysql56 --datadir=/mysql-instance/3309/data --user=mysql
|
八、启动mysql多实例
1 2 3 | > /mysql-instance/3308/mysql start
> /mysql-instance/3309/mysql start
> netstat -lntup|grep 330
|
九、登陆mysql实例
1 | > mysql -uroot -p -S /mysql-instance/3308/mysql.sock
|
