1.列出安裝的包
# rpm -qa | grep mariadb
mariadb-libs-5.5.41-2.el7_0.x86_64
2.卸載包
# rpm -e --nodeps mariadb-libs-5.5.41-2.el7_0.x86_64
3.安裝rpm包
# rpm -Uvh http://dev.mysql.com/get/mysql-community-release-el7-5.noarch.rpm
[root@localhost ~]# rpm -Uvh http://dev.mysql.com/get/mysql-community-release-el7-5.noarch.rpm

4.查看當前可用的mysql安裝資源
[root@localhost ~]# yum repolist enabled | grep "mysql.*-community.*"
Existing lock /var/run/yum.pid: another copy is running as pid 48035.
Another app is currently holding the yum lock; waiting for it to exit...
The other application is: PackageKit
Memory : 152 M RSS (557 MB VSZ)
Started: Sat Nov 25 18:27:02 2017 - 37:44 ago
State : Sleeping, pid: 48035
5.原因就是yum在自動更新 只要關掉他就可以了
[root@localhost ~]# rm -f /var/run/yum.pid
[root@localhost ~]# yum repolist enabled | grep "mysql.*-community.*"
mysql-connectors-community/x86_64 MySQL Connectors Community 42
mysql-tools-community/x86_64 MySQL Tools Community 53
mysql56-community/x86_64 MySQL 5.6 Community Server 361
6.yum方式安裝了MySQL5.6版本
[root@localhost ~]# yum -y install mysql-community-server

7.安裝成功後，將其加入開機啓動
[root@localhost ~]# systemctl enable mysqld
8.啓動mysql服務進程
[root@localhost ~]# systemctl start mysqld
9.配置mysql（設置密碼等）
[root@localhost ~]# mysql_secure_installation
SERVERS IN PRODUCTION USE! PLEASE READ EACH STEP CAREFULLY!
In order to log into MySQL to secure it, we'll need the current
password for the root user. If you've just installed MySQL, and
you haven't set the root password yet, the password will be blank,
so you should just press enter here.
Enter current password for root (enter for none):
OK, successfully used password, moving on...
Setting the root password ensures that nobody can log into the MySQL
root user without the proper authorisation.
Set root password? [Y/n] y[設置root用戶密碼]
New password:
Re-enter new password:
Password updated successfully!
Reloading privilege tables..
... Success!
By default, a MySQL installation has an anonymous user, allowing anyone
to log into MySQL without having to have a user account created for
them. This is intended only for testing, and to make the installation
go a bit smoother. You should remove them before moving into a
production environment.
Remove anonymous users? [Y/n] y[刪除匿名用戶]
... Success!
Normally, root should only be allowed to connect from 'localhost'. This
ensures that someone cannot guess at the root password from the network.
Disallow root login remotely? [Y/n] y[禁止root遠程登錄]
... Success!
By default, MySQL comes with a database named 'test' that anyone can
access. This is also intended only for testing, and should be removed
before moving into a production environment.
Remove test database and access to it? [Y/n] y[刪除test數據庫]
- Dropping test database...
ERROR 1008 (HY000) at line 1: Can't drop database 'test'; database doesn't exist
... Failed! Not critical, keep moving...
- Removing privileges on test database...
... Success!
Reloading the privilege tables will ensure that all changes made so far
will take effect immediately.
Reload privilege tables now? [Y/n] y[刷新權限]
... Success!
All done! If you've completed all of the above steps, your MySQL
installation should now be secure.
Thanks for using MySQL!
Cleaning up...
10.進入mysql
# mysql -uroot -p
11.通過window上navcat連接遠程庫
mysql> GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY '123456' WITH GRANT OPTION
-> ;
Query OK, 0 rows affected (0.00 sec)
mysql> flush privileges;
Query OK, 0 rows affected (0.00 sec)
mysql> flush privileges;
Query OK, 0 rows affected (0.00 sec)
12.防火牆設置
mysql> Ctrl-C -- exit!
Aborted
[root@localhost ~]# firewall-cmd --zone=public --add-port=3306/tcp --permanent
success
[root@localhost ~]# firewall-cmd --reload
success
