一、安装mysql-8.0.18

(1) 下载安装包

#下载前先卸载mariadb的一些东西
yum remove -y mariadb*

#然后下载安装包
mkdir /usr/local/soft && cd /usr/local/soft
wget -c https://downloads.mysql.com/archives/get/p/23/file/mysql-8.0.18-linux-glibc2.12-x86_64.tar.xz

(2) 解压

#解压
tar -xf mysql-8.0.18-linux-glibc2.12-x86_64.tar.xz

#创建软链接
ln -s mysql-8.0.18-linux-glibc2.12-x86_64 mysql

(3) 新建mysql用户以及数据目录

useradd -r -s /sbin/nologin mysql
mkdir -pv /usr/local/soft/mysql/{data,logbin,logs}

(4) 准备配置文件

vim /etc/my.cnf
#参考以下配置
[client]
port = 3306
socket = /usr/local/soft/mysql/mysql.sock

(5) 初始化数据库

#初始化前配置
touch /usr/local/soft/mysql/logs/mysql.log
chown -R mysql:mysql /usr/local/soft/mysql/

#开始初始化
/usr/local/soft/mysql/bin/mysqld --initialize --user=mysql --basedir=/usr/local/soft/mysql --datadir=/usr/local/soft/mysql/data --lower-case-table-names=1

(6) 配置环境变量

vim /etc/profile
export PATH=/usr/local/soft/mysql/bin:$PATH

source /etc/profile

(7) 准备服务启动脚本，并启动数据库服务

#准备启动脚本
cp /usr/local/soft/mysql/support-files/mysql.server /etc/init.d/mysqld

#设置开机启动
chkconfig --add mysqld

#启动
/etc/init.d/mysqld start

(8) 登录数据库，并修改密码

#查询root初始化密码
grep password /usr/local/soft/mysql/logs/mysqld-error.log

#登录，输上面命令查询到的密码
mysql -uroot -p

#修改root密码
> alter user user() identified by 'PASSWORD';

#添加用于远程连接的用户
> create user 'admin'@'%' identified by 'PASSWORD';
> grant all privileges on *.* to 'admin'@'%';
> flush privileges;
