1.将下载好的 mysql-8.0.18-el7-x86_64.tar.gz 通过 FinalShell 上传到服务器的目录，我放在 /home/zhjt 下
2.解压缩并改名为mysql
[zhjt@localhost ~]$ tar -zxvf mysql-8.0.18-el7-x86_64.tar.gz
[zhjt@localhost ~]$ mv mysql-8.0.18-el7-x86_64 mysql
12
3.创建mysql用户组及用户，并给mysql用户设置密码
[zhjt@localhost ~]# groupadd mysql
[zhjt@localhost ~]# useradd -r -g mysql mysql
[zhjt@localhost ~]# passwd mysql
更改用户 mysql 的密码 。
新的 密码：123qweGHJ
重新输入新的 密码：123qweGHJ
passwd：所有的身份验证令牌已经成功更新。

4.添加mysql配置文件：（/etc/my.cnf）
[zhjt@localhost ~]# vim /etc/my.cnf

内容如下：
# For advice on how to change settings please see
# http://dev.mysql.com/doc/refman/ ... ation-defaults.html
# *** DO NOT EDIT THIS FILE. It's a template which will be copied to the
# *** default location during install, and will be replaced if you
# *** upgrade to a newer version of MySQL.

[mysqld]

# Remove leading # and set to the amount of RAM for the most important data
# cache in MySQL. Start at 70% of total RAM for dedicated server, else 10%.
# innodb_buffer_pool_size = 128M

# Remove leading # to turn on a very important data integrity option: logging
# changes to the binary log between backups.
# log_bin

# These are commonly set, remove the # and set as required.
basedir = /home/zhjt/mysql
datadir = /home/zhjt/mysql/data
port = 3306
# server_id = .....
socket = /tmp/mysql.sock
character-set-server = utf8
skip-name-resolve
log-error = /home/zhjt/mysql/data/error.log
pid-file = /home/zhjt/mysql/data/mysql.pid

# Remove leading # to set options mainly useful for reporting servers.
# The server defaults are faster for transactions and fast SELECTs.
# Adjust sizes as needed, experiment to find the optimal values.
# join_buffer_size = 128M
# sort_buffer_size = 2M
# read_rnd_buffer_size = 2M

然后保存退出。
5.在mysql目录下新建data文件夹用于存放数据库文件
[zhjt@localhost mysql]# mkdir data

6.在mysql当前目录下设定目录的访问权限（注意后面的小点，表示当前目录）
[zhjt@localhost mysql]# chown -R mysql .
[zhjt@localhost mysql]# chgrp -R mysql .

7.初始化数据库
[zhjt@localhost mysql]# ./bin/mysqld --initialize --user=mysql --basedir=/home/zhjt/mysql --datadir=/home/zhjt/mysql/data

打开日志文件，找到初始密码：
[zhjt@localhost mysql]# /home/zhjt/mysql/data/error.log

8. 启动mysql
[zhjt@localhost mysql]# ./support-files/mysql.server start
Starting MySQL............ SUCCESS!

9.登录mysql,修改root用户密码
[zhjt@localhost mysql]# ./bin/mysql -uroot -p
