解压 MySQL 5.7 二进制包到指定目录
[root@MySQL ~]# tar zxvf mysql-5.7.18-linux-glibc2.5-x86_64.tar.gz -C /usr/local/
创建 MySQL 软链接
[root@MySQL ~]#mv /usr/local/mysql-5.7.18-linux-glibc2.5-x86_64 /usr/local/mysql
创建 MySQL 用户
[root@MySQL ~]#groupadd -r mysql
[root@MySQL ~]# useradd -r -g mysql -s /bin/false -M mysql
在 MySQL 二进制包目录中创建 mysql-files 目录 [MySQL 数据导入/导出数据专放目录]
[root@MySQL ~]# mkdir -v /usr/local/mysql/mysql-files
mkdir: created directory `/usr/local/mysql/mysql-files‘
创建多实例数据目录
[root@MySQL ~]# mkdir -vp /data/mysql_data{1..4}
mkdir: created directory /data‘ <br/>mkdir: created directory/data/mysql_data1‘
mkdir: created directory /data/mysql_data2‘ <br/>mkdir: created directory/data/mysql_data3‘
mkdir: created directory `/data/mysql_data4‘
修改 MySQL 二进制包目录的所属用户与所属组
1 [root@MySQL ~]# chown root.mysql -R /usr/local/mysql
修改 MySQL 多实例数据目录与 数据导入/导出专放目录的所属用户与所属组
[root@MySQL ~]# chown mysql.mysql -R /usr/local/mysql/mysql-files /data/mysql_data{1..4}
[mysqld1]
# 设置数据目录 [多实例中一定要不同]
datadir = /data/mysql_data1
# 设置sock存放文件名 [多实例中一定要不同]
socket = /tmp/mysql.sock1
# 设置监听开放端口 [多实例中一定要不同]
port = 3306
# 设置运行用户
user = mysql
# 关闭监控
performance_schema = off
# 设置innodb 缓存大小
innodb_buffer_pool_size = 32M
# 设置监听IP地址
bind_address = 0.0.0.0
# 关闭DNS 反向解析

[mysqld2]
datadir = /data/mysql_data2
socket = /tmp/mysql.sock2
port = 3307
user = mysql
performance_schema = off
innodb_buffer_pool_size = 32M

初始化各个实例 [ 初始化完成后会自带随机密码在输出日志中 ]
[root@MySQL ~]# /usr/local/mysql/bin/mysqld --initialize --user=mysql --basedir=/usr/local/mysql --datadir=/data/mysql_data1
[root@MySQL ~]# /usr/local/mysql/bin/mysqld --initialize --user=mysql --basedir=/usr/local/mysql --datadir=/data/mysql_data2
[root@MySQL ~]# /usr/local/mysql/bin/mysqld --initialize --user=mysql --basedir=/usr/local/mysql --datadir=/data/mysql_data3
[root@MySQL ~]# /usr/local/mysql/bin/mysqld --initialize --user=mysql --basedir=/usr/local/mysql --datadir=/data/mysql_data4
*修改环境变量
echo "export PATH=$PATH:/usr/local/mysql/bin" >> /etc/profile
source /etc/profile
复制多实例脚本到服务管理目录下 [ /etc/init.d/ ]
[root@MySQL ~]# cp /usr/local/mysql/support-files/mysqld_multi.server /etc/init.d/mysqld_multi
添加脚本执行权限
[root@MySQL ~]# chmod +x /etc/init.d/mysqld_multi
启动多实例
[root@MySQL ~]# /etc/init.d/mysqld_multi start
查看多实例状态
Reporting MySQL servers
MySQL server from group: mysqld1 is running
MySQL server from group: mysqld2 is running
MySQL server from group: mysqld3 is running
MySQL server from group: mysqld4 is running
