1.下载

https://cdn.mysql.com//Downloads/MySQL-5.7/mysql-5.7.25-linux-glibc2.12-x86_64.tar.gz

2.解压

tar -zxvf mysql-5.7.25-linux-glibc2.12-x86_64.tar.gz

mv  mysql-5.7.25-linux-glibc2.12-x86_64 /usr/local/mysql

3.创建数据目录

mkdir -p /data/mysql 

4.新建mysql用户、组及目录

# ---新建一个msyql组
# useradd -r -s /sbin/nologin -g mysql mysql -d /usr/local/mysql ---新建msyql用户禁止登录shell

改变目录属有者

#cd /usr/local/mysql
#pwd
#chown -R mysql .
#chgrp -R mysql .

chown -R mysql /data/mysql

5.配置参数
# bin/mysqld --initialize --user=mysql --basedir=/usr/local/mysql --datadir=/data/mysql

初始化后会返回一个临时密码

 

bin/mysql_ssl_rsa_setup  --datadir=/data/mysql

6.修改配置

cd /usr/local/mysql/support-files

cp mysql.server /etc/init.d/mysql

vi /etc/my.cnf

[mysqld]
server-id = 1
port = 3306

basedir =/usr/local/mysql
datadir = /data/mysql
transaction_isolation = READ-COMMITTED
character-set-server = utf8mb4
collation-server = utf8mb4_general_ci
init_connect=‘SET NAMES utf8mb4‘
lower_case_table_names = 1
max_connections = 400

7.启动mysql

/etc/init.d/mysql start

登录

mysql -hlocalhost -uroot -p

  --如果出现:-bash: mysql: command not found

  --就执行: # ln -s /usr/local/mysql/bin/mysql /usr/bin --没有出现就不用执行

输入上面的临时密码

修改密码

set password=password('root');

设置root账户的host地址(修改了才可以远程连接)

mysql>grant all privileges on *.* to 'root'@'%' identified by 'root';
mysql>flush privileges;

8.添加系统路径
vim /etc/profile
添加:
export PATH=/usr/local/mysql/bin:$PATH

source /etc/profile

9.配置mysql自动启动
# chmod 755 /etc/init.d/mysql
# chkconfig --add mysql
# chkconfig --level 345 mysql on
