卸载mariadb

[root@gitlab ~]# yum -y remove mariadb-libs

[root@gitlab ~]# mkdir /data
[root@gitlab ~]# useradd mysql -M -s /sbin/nologin

解压

[root@gitlab ~]# tar -xJvf mysql-8.0.20-linux-glibc2.12-x86_64.tar.xz 
[root@gitlab ~]# mv mysql-8.0.20-linux-glibc2.12-x86_64 /data/mysql

[root@gitlab ~]# mkdir /data/mysql/data
[root@gitlab ~]# mkdir /data/mysql/logs

安装依赖

[root@gitlab ~]# yum install gcc gcc-c++ openssl openssl-devel libaio libaio-devel  ncurses  ncurses-devel

授权

[root@gitlab ~]# chown mysql.mysql -R /data/mysql

初始化

[root@gitlab ~]# /data/mysql/bin/mysqld --user=mysql --basedir=/data/mysql/ --datadir=/data/mysql/data --initialize

创建日志文件

[root@gitlab ~]# touch /data/mysql/logs/mysql.log
[root@gitlab ~]# touch /data/mysql/logs/mysql-error.log
[root@gitlab ~]# chown mysql.mysql -R /data/mysql/logs/*

mysqld配置,拷贝启动文件到/etc/init.d/下并重命名为mysqld

[root@gitlab ~]# cp /data/mysql/support-files/mysql.server /etc/init.d/mysqld
[root@gitlab ~]# chmod +x /etc/init.d/mysqld
[root@gitlab ~]# vim /etc/init.d/mysqld
basedir=/data/mysql
datadir=/data/mysql/data

启动服务

[root@gitlab ~]# service mysqld start
