MySQL 5.6版本二進制包多實例安裝

ren tcp 安裝 starting func function defaults ogr socket

一、環境介紹
(1)系統環境介紹:
[root@linux-node2 ~]# uname -a
Linux linux-node2 3.10.0-693.5.2.el7.x86_64 #1 SMP Fri Oct 20 20:32:50 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux
[root@linux-node2 ~]# cat /etc/redhat-release 
CentOS Linux release 7.4.1708 (Core) 
(2)MySQL 5.6.x版本下載
下載地址:http://mirrors.sohu.com/mysql/MySQL-5.6/

二、MySQL安裝

(1)解壓

[root@linux-node2 ~]# tar -zxvf mysql-5.6.12-linux-glibc2.5-x86_64.tar.gz -C /usr/local/mysql-5.6.12

(2)創建軟鏈接

[root@linux-node2 ~]# ln -sv /usr/local/mysql-5.6.12 /usr/local/mysql

(3)創建mysql 用戶

[root@linux-node2 ~]# useradd -M -s /sbin/nologin mysql

(4)創建目錄結構和授權

[root@linux-node2 ~]# mkdir /data/{3306,3307}/ -p
[root@linux-node2 ~]# chown -R mysql.mysql /data

(5)初始化數據庫

[root@linux-node2 ~]# /usr/local/mysql/scripts/mysql_install_db --user=mysql --basedir=/usr/local/mysql --datadir=/data/3306/data
[root@linux-node2 ~]# /usr/local/mysql/scripts/mysql_install_db --user=mysql --basedir=/usr/local/mysql --datadir=/data/3307/data

(6)修改配置

[root@linux-node2 mysql]# vim /data/3306/my.cnf 
[client]    
port        = 3306     
socket      = /data/3306/mysql3306.sock


[mysqld]    
port        = 3306     
socket      = /data/3306/mysql3306.sock     
datadir     = /data/3306/data


[root@linux-node2 mysql]# vim /data/3307/my.cnf 
[client]    
port        = 3307     
socket      = /data/3307/mysql3307.sock


[mysqld]    
port        = 3307     
socket      = /data/3307/mysql3307.sock     
datadir     = /data/3307/data

(7)啟動多實例

[root@linux-node2 mysql]# /usr/local/mysql/bin/mysqld_safe --defaults-file=/data/3306/my.cnf &
[root@linux-node2 mysql]# /usr/local/mysql/bin/mysqld_safe --defaults-file=/data/3307/my.cnf &
[root@linux-node2 mysql]# netstat -tulnp
Active Internet connections (only servers)

(8)修改密碼

[root@linux-node2 ~]# mysqladmin -u root password "123456" -S /data/3306/mysql3306.sock 
[root@linux-node2 ~]# mysqladmin -u root password "654321" -S /data/3307/mysql3307.sock

(9)登陸數據庫

[root@linux-node2 ~]# mysql -uroot -p -S /data/3306/mysql3306.sock 
Enter password:

三、MySQL多實例啟動腳本

[root@linux-node2 ~]# cat /data/3306/mysql
#!/bin/sh
#init
port=3306
mysql_user="root"
mysql_pwd="123456"
CmdPath="/usr/local/mysql/bin"
mysql_sock="/data/${port}/mysql3306.sock"
#startup function
function_start_mysql()
{
if [ ! -e "$mysql_sock" ];then
printf "Starting MySQL...\n"
${CmdPath}/mysqld_safe --defaults-file=/data/${port}/my.cnf 2>&1 >/dev/null &
else
printf "MySQL is running...\n"
exit
fi
}
#stop function
function_stop_mysql()
{
if [ ! -e "$mysql_sock" ];then
printf "MySQL is stopped...\n"
exit
else
printf "Stoping MySQL...\n"
${CmdPath}/mysqladmin -u ${mysql_user} -p${mysql_pwd} -S /data/${port}/mysql3306.sock shutdown
fi
}
#restart function
function_restart_mysql()
{
printf "Restarting MySQL...\n"
function_stop_mysql
sleep 2
function_start_mysql
}
case $1 in
start)
function_start_mysql
;;
stop)
function_stop_mysql
;;
restart)
function_restart_mysql
;;
*)
printf "Usage: /data/${port}/mysql {start|stop|restart}\n"
esac
[root@linux-node2 ~]# cat /data/3307/mysql
#!/bin/sh
#init
port=3307
mysql_user="root"
mysql_pwd="654321"
CmdPath="/usr/local/mysql/bin"
mysql_sock="/data/${port}/mysql3307.sock"
#startup function
function_start_mysql()
{
if [ ! -e "$mysql_sock" ];then
printf "Starting MySQL...\n"
${CmdPath}/mysqld_safe --defaults-file=/data/${port}/my.cnf 2>&1 >/dev/null &
else
printf "MySQL is running...\n"
exit
fi
}
#stop function
function_stop_mysql()
{
if [ ! -e "$mysql_sock" ];then
printf "MySQL is stopped...\n"
exit
else
printf "Stoping MySQL...\n"
${CmdPath}/mysqladmin -u ${mysql_user} -p${mysql_pwd} -S /data/${port}/mysql3307.sock shutdown
fi
}
#restart function
function_restart_mysql()
{
printf "Restarting MySQL...\n"
function_stop_mysql
sleep 2
function_start_mysql
}
case $1 in
start)
function_start_mysql
;;
stop)
function_stop_mysql
;;
restart)
function_restart_mysql
;;
*)
printf "Usage: /data/${port}/mysql {start|stop|restart}\n"
esac
