CentOS7.7下二进制部署MySQL多版本多实例实战

涂鸦少年 人气:1

第一章 需求说明

  1. 部署MySQL5.7的三个多实例环境(端口分别为3307,3308,3309)
  2. 部署MySQL5.6和8.0版本数据库实例((端口分别为3316和3326)

第二章 环境准备

1.虚拟机环境

$ hostname -I 
  10.0.1.51
$ hostname
  db01
$ cat /etc/redhat-release 
  CentOS Linux release 7.7.1908 (Core)

2.虚拟机优化

# 关闭Selinux
$ setenforce 0
$ sed -i s#SELINUX=enforcing#SELINUX=disabled#g /etc/selinux/config

# 关闭防火墙
$ systemctl stop firewalld
$ systemctl disable firewalld
$ iptables-save

# 更改yum源
$ mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.ori
$ wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo
$ sed  -i '/aliyuncshttps://img.qb5200.com/download-x/d' /etc/yum.repos.d/CentOS-Base.repo 

# 添加epel源
$ wget -O /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-7.repo

# 更新yum缓存
$  yum clean all
$ yum makecache fast

# 停止NetworkManager
$ systemctl stop NetworkManager
$ systemctl disable NetworkManager

# 加大文件描述符
$ echo '* - nofile 65535' >>/etc/security/limits.conf 

3.清理环境

①卸载已安装的mysql

$ rpm -qa | grep mysql
# 结果如下
mysql-community-common-8.0.18-1.el7.x86_64
mysql-community-client-8.0.18-1.el7.x86_64
mysql-community-libs-8.0.18-1.el7.x86_64

# 使用以下命令依次删除上面的程序
$ yum remove mysql-xxx-xxx-

②删除mysql的配置文件

$ find / -name mysql|xargs rm -fr

③删除MariaDB的文件

$ rpm -qa | grep mariadb
$ rpm -e mariadb-xxx --nodeps

④删除my.cnf

$ rm -fr /etc/my.cnf

⑤检查端口是否被占用

$ which mysql
$ pkill mysqld
$ netstat -lntup|egrep '3307|3308|3309|3316|3326'

4.准备软件包

MySQL官方下载地址
下载二进制包略。

5.准备目录

$ rm -rf https://img.qb5200.com/download-x/data/*

# MySQL安装目录
$ mkdir -p https://img.qb5200.com/download-x/data/app

# MySQL数据目录
$ mkdir -p https://img.qb5200.com/download-x/data/330{7,8,9}https://img.qb5200.com/download-x/data
$ mkdir -p https://img.qb5200.com/download-x/data/33{16,26}https://img.qb5200.com/download-x/data

# Scoket目录
$ mkdir -p https://img.qb5200.com/download-x/data/socket

第三章 部署MySQL5.7多实例

1.解压软件包并制作软连接

$ tar xf mysql-5.7.28-linux-glibc2.12-x86_64.tar.gz
$ mv mysql-5.7.28-linux-glibc2.12-x86_64 mysql-5.7.28
$ ln -s https://img.qb5200.com/download-x/data/app/mysql-5.7.28 https://img.qb5200.com/download-x/data/app/mysql5728

2.创建MySQL多实例配置

# 3307实例配置
$ cat > https://img.qb5200.com/download-x/data/3307/my.cnf <<EOF 
[mysqld]                    
user=mysql                  
basedir=https://img.qb5200.com/download-x/data/app/mysql5728    
datadir=https://img.qb5200.com/download-x/data/3307https://img.qb5200.com/download-x/data     
socket=https://img.qb5200.com/download-x/data/socket/mysql3307.sock      
port=3307                   
server_id=7                  
EOF

# 3308实例配置
$ cat > https://img.qb5200.com/download-x/data/3308/my.cnf <<EOF 
[mysqld]                    
user=mysql                  
basedir=https://img.qb5200.com/download-x/data/app/mysql5728    
datadir=https://img.qb5200.com/download-x/data/3308https://img.qb5200.com/download-x/data     
socket=https://img.qb5200.com/download-x/data/socket/mysql3308.sock      
port=3308                   
server_id=8                  
EOF

# 3309实例配置
$ cat > https://img.qb5200.com/download-x/data/3309/my.cnf <<EOF 
[mysqld]                    
user=mysql                  
basedir=https://img.qb5200.com/download-x/data/app/mysql5728    
datadir=https://img.qb5200.com/download-x/data/3309https://img.qb5200.com/download-x/data     
socket=https://img.qb5200.com/download-x/data/socket/mysql3309.sock      
port=3309                   
server_id=9                  
EOF

3.创建MySQL傀儡用户并授权

$ useradd -s /sbin/nologin -M mysql
$ id mysql
$ chown -R mysql.mysql https://img.qb5200.com/download-x/data

4.初始化

$ https://img.qb5200.com/download-x/data/app/mysql5728/bin/mysqld --initialize-insecure --user=mysql --basedir=https://img.qb5200.com/download-x/data/app/mysql5728 --datadir=https://img.qb5200.com/download-x/data/3307https://img.qb5200.com/download-x/data
$ echo $?

$ https://img.qb5200.com/download-x/data/app/mysql5728/bin/mysqld --initialize-insecure --user=mysql --basedir=https://img.qb5200.com/download-x/data/app/mysql5728 --datadir=https://img.qb5200.com/download-x/data/3308https://img.qb5200.com/download-x/data
$ echo $?

$ echo $?

5.编写systemd启动脚本

# 3307实例启动的服务脚本
$ cat > /etc/systemd/system/mysqld3307.service <<EOF
[Unit]
Description=MySQL Server
Documentation=man:mysqld(8)
Documentation=http:/https://img.qb5200.com/download-x/dev.mysql.comhttps://img.qb5200.com/download-x/doc/refman/en/using-systemd.html

port=3326                  
server_id=26                  
EOF

3.创建mysql傀儡用户并授权

$ chown -R mysql.mysql https://img.qb5200.com/download-x/data

4.安装依赖并初始化

$ yum install -y perl-DBD-MySQL perl-Config-Tiny epel-release perl-Log-Dispatch perl-Parallel-ForkManager perl-Time-HiRes
$ https://img.qb5200.com/download-x/data/app/mysql8018/bin/mysqld --initialize-insecure --user=mysql --basedir=https://img.qb5200.com/download-x/data/app/mysql8018 --datadir=https://img.qb5200.com/download-x/data/3326https://img.qb5200.com/download-x/data
$ echo $?

5.编写systemd启动脚本

cat > /etc/systemd/system/mysqld3326.service <<EOF
[Unit]
Description=MySQL Server
Documentation=man:mysqld(8)
Documentation=http:/https://img.qb5200.com/download-x/dev.mysql.comhttps://img.qb5200.com/download-x/doc/refman/en/using-systemd.html
After=network.target
After=syslog.target
[Install]
WantedBy=multi-user.target
[Service]
User=mysql
Group=mysql
ExecStart=https://img.qb5200.com/download-x/data/app/mysql8018/bin/mysqld --defaults-file=https://img.qb5200.com/download-x/data/3326/my.cnf
LimitNOFILE = 5000
EOF

6.启动实例

$ systemctl start mysqld3326.service 
$ netstat -lntup|grep mysqld
  tcp6       0      0 :::3326    :::*    LISTEN      2686/mysqld  

7.绝对路径登录MySQL实例

$ https://img.qb5200.com/download-x/data/app/mysql8018/bin/mysql -S https://img.qb5200.com/download-x/data/socket/mysql3326.sock

至此,在同一台服务器上部署多版本MySQL多实例完成,可是使用一下命令验证:

[root@db01 ~]# netstat -lntup|grep mysqld
tcp6       0      0 :::3326    :::*        LISTEN      2686/mysqld         
tcp6       0      0 :::33060   :::*        LISTEN      2686/mysqld         
tcp6       0      0 :::3307    :::*        LISTEN      2093/mysqld         
tcp6       0      0 :::3308    :::*        LISTEN      2127/mysqld         
tcp6       0      0 :::3309    :::*        LISTEN      2161/mysqld         
tcp6       0      0 :::3316    :::*        LISTEN      2516/mysqld
