CentOS7同时安装运行多版本MySQL(使用mysqld_multi)

一、准备工作

   在官网下载不同版本安装包(以5.6和8.0为例，5.7版本步骤仿照8.0即可)，上传到服务器

• mysql-5.6.22-linux-glibc2.5-x86_64.tar.gz
• mysql-8.0.36-linux-glibc2.12-x86_64.tar.xz

tar xf mysql-5.6.22-linux-glibc2.5-x86_64.tar.gz
tar xf mysql-8.0.36-linux-glibc2.12-x86_64.tar.xz

mkdir -p /usr/local/mysql/5.6.22
mkdir -p /usr/local/mysql/8.0.36

## 创建软连接
ln -s /usr/local/mysql/5.6.22 /usr/local/mysql56
ln -s /usr/local/mysql/8.0.36 /usr/local/mysql80

mv mysql-5.6.22-linux-glibc2.5-x86_64/* /usr/local/mysql56
mv mysql-8.0.36-linux-glibc2.12-x86_64/* /usr/local/mysql80

mkdir -p /usr/local/mysql56/data
mkdir -p /usr/local/mysql80/data

rm -rf mysql-5.6.22-linux-glibc2.5-x86_64 
rm -rf mysql-8.0.36-linux-glibc2.12-x86_64
