1. 下载mysql-8.0.17-linux-glibc2.12-x86_64.tar.xz:
   https://dev.mysql.com/downloads/mysql/
   

2. 拷贝文件mysql-8.0.17-linux-glibc2.12-x86_64.tar.xz至 linux 系统目录： /usr/local/src

3. tar -xf mysql-8.0.17-linux-glibc2.12-x86_64.tar.xz， 得到文件：mysql-8.0.17-linux-glibc2.12-x86_64.tar

4. tar -zxvf mysql-8.0.17-linux-glibc2.12-x86_64.tar

5. mv mysql-8.0.17-linux-glibc2.12-x86_64 /usr/local/

6. mv /usr/local/ mysql-8.0.17-linux-glibc2.12-x86_64 /usr/local/zwk_mysql

7. mkdir /usr/local/zwk_data

8. groupadd zwkmysql

9. useradd -g zwkmysql zwkmysql

10. chown -R zwkmysql.zwkmysql /usr/local/zwk_mysql /usr/local/zwk_data

11. 初始化数据库

11.1 创建mysql_install_db安装文件 (好像没有用)
mkdir mysql_install_db
chmod 777 ./mysql_install_db
11.2 初始化
/usr/local/zwk_mysql/bin/mysqld --initialize --user=zwkmysql --basedir=/usr/local/zwk_mysql --datadir=/usr/local/zwk_data

//初始化数据库
/usr/local/mysql/bin/mysqld (mysqld 8.0.11) initializing of server in progress as process 5826
[Server] A temporary password is generated for root@localhost: twi=Tlsi<0O!
/usr/local/mysql/bin/mysqld (mysqld 8.0.11) initializing of server has completed

记录好自己的临时密码：
twi=Tlsi<0O!

这里可能遇到了问题：没有libnuma.so.1
zsh: command not found: mysqld
./bin/mysqld --initialize
./bin/mysqld: error while loading shared libraries: libnuma.so.1: cannot open shared object file: No such file or directory

解决办法：
yum install libaio
安装文件

12. mysql配置

cp /usr/local/zwk_mysql/support-files/mysql.server /etc/init.d/
修改my.cnf文件

vim /etc/my.cnf

[mysqld]
basedir = /usr/local/zwk_mysql
datadir = /usr/local/zwk_data
socket = /usr/local/ zwk_mysql/zwkmysql.sock
character-set-server=utf8
port = 3306
sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES
[client]
socket = /usr/local/ zwk_mysql/ zwkmysql.sock
default-character-set=utf8
[mysqld_safe]
log-error=/var/log/mariadb/mariadb.log
pid-file=/usr/local/zwk_data/zwkmysql.pid
esc保存
:wq 退出

13. 修改日志文件的权限（这一定要改，不然无法启动）
    chown -R zwkmysql.zwkmysql /var/log/mariadb
    chown -R zwkmysql.zwkmysql /var/log/mariadb/mariadb.log

14. 建立MySQL服务
    cp -a /usr/local/zwk_mysql/support-files/mysql.server /etc/init.d/zwkmysqld

chmod +x /etc/init.d/ zwkmysqld

添加到系统服务
chkconfig --add zwkmysqld

检查服务是否生效
chkconfig --list mysqld

15. 配置全局环境变量

编辑 / etc/profile 文件

vi /etc/profile

在 profile 文件底部添加如下两行配置，保存后退出

export PATH=$PATH:/usr/local/zwk_mysql/bin:/usr/local/zwk_mysql/lib

export PATH

设置环境变量立即生效
source /etc/profile

16. 修改：vim /etc/init.d/zwkmysqld

17. 启动MySQL服务
    service mysql start

18. 登录MySQL
    mysql -uroot -p密码

修改密码：
alter user ‘root’@’locahost’ identified by ‘P123456’; #对应的换成你自己的密码即可了。
