注：部署双实例前，首先需要部署单实例，单实例部署详情如下：

https://www.cnblogs.com/wangqiner/p/9081002.html

1、如已经安装完成单实例，需要先停止单实例运行，接下来进行多实例部署

/etc/init.d/mysqld stop
chkconfig mysqld off

2、已经制作好多实例配置文件及启动文件，以下为下载地址：

3、上传data.tar.gz到根目录，然后tar解压

[[email protected] /]# tar xf data.tar.gz

[[email protected] /]# tree /data
data
├── 3306
│   ├── my.cnf
│   └── mysql
└── 3307
├── my.cnf
└── mysql

4、授权所有者、所属组及文件权限并查看

chown -R mysql.mysql /data/

　[[email protected] /]# find /data -name mysql|xargs ls -l
　-rw-r--r-- 1 root root 1345 Apr 26 2017 /home/data/3306/mysql
　-rw-r--r-- 1 root root 1345 Apr 26 2017 /home/data/3307/mysql

　[[email protected] home]# find /home/data -name mysql|xargs chmod 700
　[[email protected] home]# find /home/data -name mysql|xargs ls -l
　-rwx------ 1 root root 1345 Apr 26 2017 /home/data/3306/mysql
　-rwx------ 1 root root 1345 Apr 26 2017 /home/data/3307/mysql
　[[email protected] home]#

5、进入MySQL初始化文件目录

cd /application/mysql/scripts

6、初始化3306,3307 两个实例（为了生成MySQL data下数据关联及文件）

./mysql_install_db  --defaults-file=/data/3306/my.cnf --basedir=/application/mysql/ --datadir=/data/3306/data --user=mysql

------------分别执行--------------

./mysql_install_db  --defaults-file=/data/3307/my.cnf --basedir=/application/mysql/ --datadir=/data/3307/data --user=mysql

7、环境变量设置，如已经配置，可跳过

echo ‘export PATH=/application/mysql/bin:$PATH‘ >>/etc/profile
source  /etc/profile

8、启动前为保证没有错误文件的报错，提前创建错误日志文件及授权所有者及所属组

touch /data/3306/oldboy_3306.err
touch /data/3307/oldboy_3307.err
chown mysql.mysql /data/3306/oldboy_3306.err
chown mysql.mysql /data/3307/oldboy_3307.err

9、启动MySQL多实例

---命令---
/data/3306/mysql start
/data/3307/mysql start

---展示---

　[[email protected] data]# /data/3306/mysql start
　Starting MySQL...
　[[email protected] data]# /data/3307/mysql start
　Starting MySQL...

10、查看MySQL端口是否正常启动

[[email protected] data]# ss -lntup
Netid  State      Recv-Q Send-Q   Local Address:Port     Peer Address:Port 
tcp    LISTEN     0      600                 :::3306               :::*      users:(("mysqld",36610,11))
tcp    LISTEN     0      600                 :::3307               :::*      users:(("mysqld",37337,11))

11、分别登录进入MySQL多实例

---进入命令---

　mysql -S /data/3306/mysql.sock
　mysql -S /data/3307/mysql.sock

----展示-----

[[email protected] data]# mysql -S /data/3306/mysql.sock
