rpm安装mysql5.7

1.下载安装包

下载地址:https://cdn.mysql.com//Downloads/MySQL-5.7/mysql-5.7.27-1.el7.x86_64.rpm-bundle.tar

上传到 /home 目录下

解压安装包

 tar -xf mysql-5.7.27-1.el7.x86_64.rpm-bundle.tar -C /home/mysql/

查询并卸载系统自带的Mariadb

rpm -qa | grep mariadb

rpm -e –nodeps 文件名

查询并卸载系统老旧版本的Mysql

rpm -qa | grep mysql

rpm -e –nodeps 文件名

安装libaio环境(已经存在不需要)

yum install libaio

2.执行Rpm包安装(按顺序)

rpm -ivh mysql-community-common-5.7.27-1.el7.x86_64.rpm

rpm -ivh mysql-community-libs-5.7.27-1.el7.x86_64.rpm

rpm -ivh mysql-community-devel-5.7.27-1.el7.x86_64.rpm

rpm -ivh mysql-community-libs-compat-5.7.27-1.el7.x86_64.rpm

rpm -ivh mysql-community-client-5.7.27-1.el7.x86_64.rpm

rpm -ivh mysql-community-server-5.7.27-1.el7.x86_64.rpm

3.启动mysql服务

查看mysql服务是否启动

service mysqld status

启动服务:

systemctl start mysqld

3.重置root密码

查看随机生成的密码

grep 'temporary password' /var/log/mysqld.log

修改root用户密码

mysql -u root -p

mysql> Enter password: (输入刚才查询到的随机密码)

mysql> SET PASSWORD FOR 'root'@'localhost'= "新密码";

4.开放外部网段访问3306端口

mysql>GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY 'Jstw@123' WITH GRANT OPTION;

mysql>FLUSH PRIVILEGES;

mysql> exit

5.这里设置开机自启动

方法一   、vi /etc/rc.local       添加service mysqld start

方法二  、 执行 systemctl enable mysqld.service   

(# 注意systemctl 中规定、服务的配置文件要以.service 为后缀

开启防火墙mysql 3306端口的外部访问

firewall-cmd –zone=public –add-port=3306/tcp –permanent

firewall-cmd –reload

查看已开启的端口

firewall-cmd –list-all

netstat -ntpl (TCP类型已开放的端口)
