Posted 2021-01-21 只许澎湃不许爱

1.创建安装目录：
[[email protected] ~]# mkdir /application

2.下载二进制安装包：
wget https://downloads.mysql.com/archives/get/file/mysql-5.6.40-linux-glibc2.12-x86_64.tar.gz

3.解压二进制包：
[[email protected] ~]# tar xf mysql-5.6.40-linux-glibc2.12-x86_64.tar.gz

4.移动解压目录
[[email protected] ~]# mv mysql-5.6.40-linux-glibc2.12-x86_64 /application/mysql-5.6.40

5.做MySQL软连接
[[email protected] scripts]# ln -s /application/mysql-5.6.40/ /application/mysql

6.创建MySQL用户
[[email protected] ~]# useradd mysql -s /sbin/nologin -M

7.进入配置文件及启动脚本目录
[[email protected] ~]# cd /application/mysql-5.6.40/support-files

8.拷贝配置文件到/etc/my.cnf
[[email protected] support-files]# cp my-default.cnf /etc/my.cnf

9.拷贝启动脚本
[[email protected] support-files]# cp mysql.server /etc/init.d/mysqld

10.初始化MySQL
[[email protected] scripts]# cd /application/mysql-5.6.40/scripts
[[email protected] scripts]# ./mysql_install_db --user=mysql --basedir=/application/mysql --datadir=/application/mysql/data
--user 指定mysql用户
--basedir 指定mysql安装目录
--datadir 指定mysql数据目录

11.修改MySQL启动脚本及启动程序
[[email protected] scripts]# sed -i ‘s#/usr/local#/application#g‘ /etc/init.d/mysql /application/mysql/bin/mysqld_safe

12.启动MySQL
[[email protected] scripts]# /etc/init.d/mysqld start

13.添加环境变量
[[email protected] scripts]# echo ‘export PATH="/application/mysql/bin:$PATH"‘ > /etc/profile.d/mysql.sh

14.加载环境变量
[[email protected] scripts]# source /etc/profile

15.添加systemd启动

[[email protected] scripts]# vim /etc/systemd/system/mysqld.service
[Unit]
Description=MySQL Server
Documentation=man:mysqld(8)
Documentation=https://dev.mysql.com/doc/refman/en/using-systemd.html

ExecStart=/application/mysql/bin/mysqld --defaults-file=/etc/my.cnf
LimitNOFILE = 5000

MySQL查看报错：
[[email protected] scripts]# tail -100 /application/mysql/data/db01.err
