CentOS7下安装MySQL5.7安装与配置(YUM)

时间:2022-06-13 21:07:57

安装环境:CentOS7 64位 MINI版,安装MySQL5.7

参照http://www.centoscn.com/mysql/2016/0626/7537.html


1、配置YUM源

MySQL官网中下载YUM源rpm安装包:http://dev.mysql.com/downloads/repo/yum/ ,我是下载mysql5.7-11这一个,下载到Windows桌面

用sshsecureClient上传到Linux服务器的/usr/java文件夹里面

然后Linux进入这个目录/usr/java

# 安装mysql源

# yum localinstall mysql57-community-release-el7-11.noarch.rpm

检查mysql源是否安装成功,看到图所示表示安装成功

shell> yum repolist enabled | grep "mysql.*-community.*"

2、安装MySQL

shell> yum install mysql-community-server

3、启动MySQL服务

shell> systemctl start mysqld

查看MySQL的启动状态

shell> systemctl status mysqld
● mysqld.service - MySQL Server
Loaded: loaded (/usr/lib/systemd/system/mysqld.service; disabled; vendor preset: disabled)
Active: active (running) since 五 2016-06-24 04:37:37 CST; 35min ago
Main PID: 2888 (mysqld)
CGroup: /system.slice/mysqld.service
└─2888 /usr/sbin/mysqld --daemonize --pid-file=/var/run/mysqld/mysqld.pid

624 04:37:36 localhost.localdomain systemd[1]: Starting MySQL Server...
624 04:37:37 localhost.localdomain systemd[1]: Started MySQL Server.

4、开机启动

shell> systemctl enable mysqld
shell> systemctl daemon-reload

5、修改root默认密码

mysql安装完成之后,在/var/log/mysqld.log文件中给root生成了一个默认密码。通过下面的方式找到root默认密码,然后登录mysql进行修改:

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

shell> mysql -uroot -p
mysql> ALTER USER 'root'@'localhost' IDENTIFIED BY 'MyNewPass4!';

或者

mysql> set password for 'root'@'localhost'=password('MyNewPass4!');

6、添加远程登录用户

默认只允许root帐户在本地登录,如果要在其它机器上连接mysql,必须修改root允许远程连接,或者添加一个允许远程连接的帐户,为了安全起见,我添加一个新的帐户:

mysql> GRANT ALL PRIVILEGES ON *.* TO 'yangxin'@'%' IDENTIFIED BY 'Yangxin0917!' WITH GRANT OPTION;

7、配置默认编码为utf8

修改/etc/my.cnf配置文件,在[mysqld]下添加编码配置,如下所示:

[mysqld]
character_set_server=utf8
init_connect='SET NAMES utf8'

重新启动mysql服务,查看数据库默认编码如下所示:

默认配置文件路径:  配置文件:/etc/my.cnf  日志文件:/var/log//var/log/mysqld.log  服务启动脚本:/usr/lib/systemd/system/mysqld.service  socket文件:/var/run/mysqld/mysqld.pid
