1 慣例毛病的yum裝置辦法：
在前文中記敘了CentOS 6.5體系中經由過程yum方法疾速地搭建了LNMP情況，那末能否也能在CentOS 7或CentOS 7.1體系中依葫蘆畫瓢裝置MySql5.6.24呢？謎底能否定的。
[root@typecodes ~]# yum -y install mysql mysql-server mysql-devel .....................。 ....省略部門裝置進程.... .....................。 Installed: mariadb.x86_64 1:5.5.41-2.el7_0 mariadb-devel.x86_64 1:5.5.41-2.el7_0 Dependency Installed: keyutils-libs-devel.x86_64 0:1.5.8-3.el7 krb5-devel.x86_64 0:1.12.2-14.el7 libcom_err-devel.x86_64 0:1.42.9-7.el7 libselinux-devel.x86_64 0:2.2.2-6.el7 libsepol-devel.x86_64 0:2.1.9-3.el7 libverto-devel.x86_64 0:0.2.5-4.el7 openssl-devel.x86_64 1:1.0.1e-42.el7.4 pcre-devel.x86_64 0:8.32-14.el7 zlib-devel.x86_64 0:1.2.7-13.el7 Complete!
從下面的裝置成果可以看出，沒有裝置mysql數據庫，而是裝置了mariadb數據！由於在CentOS 7和CentOS 7.1體系中，默許裝置的mysql是它的分支mariadb。這裡援用下百度百科關於mariadb的描寫：
MariaDB數據庫治理體系是MySQL的一個分支，重要由開源社區在保護，采取GPL受權允許 MariaDB的目標是完整兼容MySQL，包含API和敕令行，使之能輕松成為MySQL的取代品。
是以，上面這些正常的MySQL操作都是有效的：
#######沒法把mysql辦事參加體系啟動 [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. #######沒有裝置mysql相干包 [root@typecodes ~]# rpm -qa |grep mysql php-mysql-5.4.16-23.el7_0.3.x86_64 [root@typecodes ~]#
2 准確的裝置辦法：
盡人皆知，Linux體系自帶的repo是不會主動更新每一個軟件的最新版本（根本都是比擬靠後的穩固版），所以沒法經由過程yum方法裝置MySQL的高等版本。所以我們須要先裝置帶有以後可用的mysql5系列社區版資本的rpm包。
#######裝置rpm包 [root@typecodes ~]# rpm -Uvh http://dev.mysql.com/get/mysql-community-release-el7-5.noarch.rpm
Retrieving http://dev.mysql.com/get/mysql-community-release-el7-5.noarch.rpm Preparing... ################################# [100%] Updating / installing... 1:mysql-community-release-el7-5 ################################# [100%]
這時候檢查以後可用的mysql裝置資本：
[root@typecodes ~]# yum repolist enabled | grep "mysql.*-community.*"
mysql-connectors-community/x86_64 MySQL Connectors Community 14 mysql-tools-community/x86_64 MySQL Tools Community 17 mysql56-community/x86_64 MySQL 5.6 Community Server 139
從下面的列表可以看出， mysql56-community/x86_64 和 MySQL 5.6 Community Server 可使用。
是以，我們便可以直接用yum方法裝置了MySQL5.6版本了。
[root@typecodes ~]# yum -y install mysql-community-server

3 MySQL裝置完成後，停止相干設置裝備擺設
裝置完MySQL後，須要停止一些基本設置裝備擺設任務：
#######裝置勝利後，將其參加開機啟動 [root@typecodes ~]# systemctl enable mysqld #######啟動mysql辦事過程 [root@typecodes ~]# systemctl start mysqld #######設置裝備擺設mysql（設置暗碼等） [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用戶暗碼] 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 [制止root長途登錄] ... 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...
4.能夠有用的MySQL設置裝備擺設優化
在原始設置裝備擺設文件 /etc/my.cnf 基本上，在 [mysqld] 節內增長設置裝備擺設參數。現實運用中，請按硬件及負載酌情修正。
