发布时间 - 2026-01-11 01:45:38 点击率：次1查看Linux发行版本
[root@typecodes ~]# cat /etc/redhat-release
CentOS Linux release 7.2.1511 (Core)
2 下载MySQL官方的Yum Repository
根据Linux发行版本（CentOS、Fedora都属于红帽系），从mysql官方（http://dev.mysql.com/downloads/repo/yum/）获取Yum Repository。
[root@typecodes ~]# wget -i http://dev.mysql.com/get/mysql57-community-release-el7-7.noarch.rpm --2016-02-03 18:36:02-- http://dev.mysql.com/get/mysql57-community-release-el7-7.noarch.rpm Resolving dev.mysql.com (dev.mysql.com)... 137.254.60.11 Connecting to dev.mysql.com (dev.mysql.com)|137.254.60.11|:80... connected.

[root@typecodes ~]# clear
最后的截图：
4 启动数据库：
[root@typecodes ~]# systemctl start mysqld.service
然后使用命令systemctl status mysqld.service查看MySQL数据库启动后的服务状态：
5 获取初始密码
使用YUM安装并启动MySQL服务后，MySQL进程会自动在进程日志中打印root用户的初始密码：
#######从mysql进程日志中获取root用户的初始密码：ra%yk7urCBIh [root@typecodes ~]# grep "password" /var/log/mysqld.log 2016-02-03T10:42:17.272166Z 1 [Note] A temporary password is generated for root@localhost: ra%yk7urCBIh 2016-02-03T10:42:36.776875Z 2 [Note] Access denied for user 'root'@'localhost' (using password: NO) 2016-02-03T10:42:52.063138Z 3 [Note] Access denied for user 'root'@'localhost' (using password: NO) 2016-02-03T10:42:57.564373Z 4 [Note] Access denied for user 'root'@'localhost' (using password: NO) 2016-02-03T10:43:01.477007Z 5 [Note] Access denied for user 'root'@'localhost' (using password: NO) 2016-02-03T10:46:03.642008Z 6 [Note] Access denied for user 'root'@'localhost' (using password: NO) 2016-02-03T10:46:11.217889Z 7 [Note] Access denied for user 'root'@'localhost' (using password: NO) 2016-02-03T10:47:44.755199Z 0 [Note] Shutting down plugin 'validate_password' 2016-02-03T10:47:46.505844Z 0 [Note] Shutting down plugin 'sha256_password' 2016-02-03T10:47:46.505851Z 0 [Note] Shutting down plugin 'mysql_native_password'
6 修改root用户密码
使用小节5中获取的root用户的初始密码，然后进行修改：
set global validate_password_policy =0;//默认是1，即MEDIUM，所以刚开始设置的密码必须符合长度，且必须含有数字，小写或大写字母，特殊字符。
set global validate_password_length=4;//指定了密码中数据的长度 alter user root@localhost identified by 'crow';//修改密码
增加远程访问权限
GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY 'crow' WITH GRANT OPTION; FLUSH PRIVILEGES;
退出mysql，然后重启服务
systemctl restart mysqld
防火墙打开3306端口
firewall-cmd --zone=public --add-port=3306/tcp --permanent
重启防火墙
firewall-cmd --reload [root@typecodes ~]# mysql -uroot -p Enter password: #######输入默认的root密码后回车 Welcome to the MySQL monitor. Commands end with ; or \g.

Type '\c' to clear the current input statement. mysql> ALTER USER 'root'@'localhost' IDENTIFIED BY 'new password'; Query OK, 0 rows affected (0.00 sec) mysql> exit Bye
7 安装完毕
至此，使用在CentOS7中使用YUM方法安装MySQL5.7.10数据库完毕。如下所示，可以使用新的root密码登陆MySQL了。
[root@typecodes ~]# mysql -uroot -ppassword mysql: [Warning] Using a password on the command line interface can be insecure. Welcome to the MySQL monitor. Commands end with ; or \g.

附录1：查看MySQL数据库的配置信息
MySQL的配置文件依然是/etc/my.cnf，其它安装信息可以通过mysql_config命令查看。其中，动态库文件存放在/usr/lib64/mysql目录下。
附录2：对于C/C++等开发者
由于需要用到类似mysql.h等头文件，需要执行下面的命令安装mysql开发版本即可。
[root@typecodes ~]# yum -y install mysql-community-devel
附录3：删除MySQL的Repository
因为小节3中安装了MySQL的Yum Repository，所以以后每次执行yum操作时，都会去检查更新。如果想要去掉这种自动检查操作的话，可以使用如下命令卸载MySQL的Repository即可。
[root@typecodes ~]# yum -y remove mysql57-community-release-el7-7.noarch update 2017.04.10 11:10
使用上面的yum方法也可以安装目前mysql官网上最新的版本mysql5.7.18。只要替换小节2中rmp包的版本即可，后续操作步骤不变。
