一、 檢查系統(tǒng)中是否已安裝了mysql服務(wù)或開發(fā)包依賴等

[bigdata@bigdata-pro02 ~]$ rpm -qa | grep mysql mysql-libs-5.1.73-3.el6_5.x86_64

如果檢查存在一些安裝包，則使用 rpm -e –nodeps [安裝包1] [安裝包2] […] 將已有的安裝包卸載。
這里需要切換到root用戶

[root@bigdata-pro02 ~]# rpm -e --nodeps mysql-libs-5.1.73-3.el6_5.x86_64 [root@bigdata-pro02 ~]#

二、檢查yum源上可以使用的安裝包（如果對(duì)mysql版本有要求，可以修改yum源的配置）

使用yum list | grep mysql 來(lái)檢查可以使用的安裝包

[root@bigdata-pro02 ~]# yum list | grep mysql-server mysql-server.x86_64                            5.1.73-8.el6_8               @base

三、安裝mysql-server ，使用yum install 命令，安裝過(guò)程中會(huì)自動(dòng)把所有依賴的包自動(dòng)下載和安裝

[root@bigdata-pro02 ~]# yum install mysql-server.x86_64 -y Loaded plugins: fastestmirror, refresh-packagekit, security Setting up Install Process Loading mirror speeds from cached hostfile

檢查系統(tǒng)中是否安裝mysql

[root@bigdata-pro02 ~]# rpm -qa | grep mysql mysql-5.1.73-8.el6_8.x86_64 mysql-libs-5.1.73-8.el6_8.x86_64 mysql-server-5.1.73-8.el6_8.x86_64

檢查mysql命令所在位置

[root@bigdata-pro02 ~]# which mysql /usr/bin/mysql

四、啟動(dòng)mysqld服務(wù)

[root@bigdata-pro02 ~]# service mysqld status mysqld is stopped [root@bigdata-pro02 ~]# service mysqld start Initializing MySQL database:  Installing MySQL system tables... OK Filling help tables... OK  To start mysqld at boot time you have to copy support-files/mysql.server to the right place for your system  PLEASE REMEMBER TO SET A PASSWORD FOR THE MySQL root USER ! To do so, start the server, then issue the following commands:  /usr/bin/mysqladmin -u root password 'new-password' /usr/bin/mysqladmin -u root -h bigdata-pro02.mars.com password 'new-password' **# 以上為兩種新建root用戶并設(shè)置密碼的方式**  Alternatively you can run: /usr/bin/mysql_secure_installation  which will also give you the option of removing the test databases and anonymous user created by default.  This is strongly recommended for production servers.  See the manual for more instructions.  You can start the MySQL daemon with: cd /usr ; /usr/bin/mysqld_safe &  You can test the MySQL daemon with mysql-test-run.pl cd /usr/mysql-test ; perl mysql-test-run.pl  Please report any problems with the /usr/bin/mysqlbug script!                                                             [  OK  ] Starting mysqld:                                           [  OK  ]

五、使用mysql數(shù)據(jù)庫(kù)

添加root用戶并設(shè)置密碼

[root@bigdata-pro02 ~]# /usr/bin/mysqladmin -u root password '123456'

登錄mysql數(shù)據(jù)庫(kù)

[root@bigdata-pro02 ~]# mysql -uroot -p123456 Welcome to the MySQL monitor.  Commands end with ; or g.
