use -h add 使用 chkconfig sha perl print back 

#######無法把mysql服務加入系統啟動
[root@typecodes ~]# chkconfig mysqld on
error reading information on service mysqld: No such file or directory
#######啟動不了mysql
[root@typecodes ~]# service mysqld start
Redirecting to /bin/systemctl start  mysqld.service
Failed to issue method call: Unit mysqld.service failed to load: No such file or directory.
#######沒有安裝mysql相關包
[root@typecodes ~]# rpm -qa |grep mysql
php-mysql-5.4.16-23.el7_0.3.x86_64
[root@typecodes ~]#

眾所周知，Linux系統自帶的repo是不會自動更新每個軟件的最新版本（基本都是比較靠後的穩定版），所以無法通過yum方式安裝MySQL的高級版本。所以我們需要先安裝帶有當前可用的mysql5系列社區版資源的rpm包。

#######安裝rpm包

安裝完MySQL後，需要進行一些基礎配置工作：

#######安裝成功後，將其加入開機啟動
[root@typecodes ~]# systemctl enable mysqld

#######啟動mysql服務進程
[root@typecodes ~]# systemctl start mysqld

#######配置mysql（設置密碼等）
[root@typecodes ~]# mysql_secure_installation

NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MySQL
      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!
