第一步，下载MySQL安装

[[e-mail] ~]# cd /home/data/




[[e-mail] data]# ls




get-docker.sh  nginx-1.10.1  nginx-1.10.1.tar.gz  redis-5.0.3  redis-5.0.3.tar.gz  server-jre-8u131-linux-x64.tar.gz  zookeeper-3.4.10.tar.gz



[[e-mail] data]# wget https://dev.mysql.com/get/mysql57-community-release-el7-11.noarch.rpm

如果提示wget命令不存在，先执行

yum -y install wget

下载完成后

多了一个mysql57-xxx的文件，这个就是mysql安装源

安装mysql安装源

[[e-mail] data]# yum -y localinstall mysql57-community-release-el7-11.noarch.rpm 

第二步，在线安装MySQL

[[e-mail] data]# yum -y install mysql-community-server

下载的东西有点多，需要等待一会

第三步，启动MySQL服务

[[e-mail] data]# systemctl start mysqld

第四步，设置开机启动

[[e-mail] data]# systemctl enable mysqld




 



[[e-mail] data]# systemctl daemon-reload

第五步，修改root登录密码

mysql安装完成之后，会在/var/log/mysqld.log文件中给root生成了一个临时的默认密码。

[[e-mail] data]# vim /var/log/mysqld.log

复制此密码，使用此密码登录root

[[e-mail] data]# mysql -u root -p




Enter password: 



Welcome to the MySQL monitor.  Commands end with ; or \g.



Your MySQL connection id is 2



Server version: 5.7.25

Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.



 



mysql> 

修改密码， mysql5.7默认密码策略要求密码必须是大小写字母数字特殊字母的组合，至少8位

mysql> ALTER USER 'root'@'localhost' IDENTIFIED BY '[e-mail]';



Query OK, 0 rows affected (0.01 sec)



 

第六步，设置允许远程登录

mysql> GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY '[e-mail]' WITH GRANT OPTION;



Query OK, 0 rows affected, 1 warning (0.00 sec)

第七步，退出

mysql> exit




Bye

第八步，防火墙开放3306端口

[[e-mail] data]# firewall-cmd --zone=public --add-port=3306/tcp --permanent




 



success



 



[[e-mail] data]# firewall-cmd --reload




 



success



 



[[e-mail] data]# 

第九步，配置mysql默认编码为utf-8

修改/etc/my.cnf配置文件，在[mysqld]下添加编码配置

character_set_server=utf8

init_connect='SET NAMES utf8'

:wq!保存退出

第十步，重启MySQL

[[e-mail] data]# systemctl restart mysqld

第十一步，登录root用户查看编码

第十二步，测试远程连接
