Centos8 安装 MySQL8.0.26

下载

• 选择 Red Hat Enterprise Linux / Oracle Linux
• 选择 Red Hat Enterprise Linux 8 / Oracle Linux (x86, 64-bit)
• 下载 RPM Bundle (mysql-8.0.26-1.el8.x86_64.rpm-bundle.tar) 这是多个rpm打包的文件

也可以直接在服务器上用wget

wget https://cdn.mysql.com//Downloads/MySQL-8.0/mysql-8.0.26-1.el8.x86_64.rpm-bundle.tar

安装

yum update
tar xvf mysql-8.0.26-1.el8.x86_64.rpm-bundle.tar 
# 按顺序执行
rpm -ivh mysql-community-common-8.0.26-1.el8.x86_64.rpm
rpm -ivh mysql-community-client-plugins-8.0.26-1.el8.x86_64.rpm
rpm -ivh mysql-community-libs-8.0.26-1.el8.x86_64.rpm
rpm -ivh mysql-community-client-8.0.26-1.el8.x86_64.rpm
rpm -ivh mysql-community-server-8.0.26-1.el8.x86_64.rpm

安装server时会要求perl和libaio, 如果没有安装, 需要先用yum install perl libaio安装一下.
上面的安装结束后会提示

[root@db backup]# rpm -ivh mysql-community-server-8.0.26-1.el8.x86_64.rpm

• https://access.redhat.com/solutions/4154291, Due to the systemd change, any package using /var/run will need to be updated to attempt to remove the logs., 根据Systemd的修改, 任何使用 /var/run 这个目录的软件都需要更新路径来避免出现这个提示.
• https://bugs.gentoo.org/768051 A workaround of this case is to edit /usr/lib/tmpfiles.d/mysql.conf, Do not edit /usr/lib/tmpfiles.d/mysql.conf. Copy that file to /etc/tmpfiles.d and edit it there if you need to.
