1. Überprüfen Sie, ob die MySQL-Dienst- oder Entwicklungspaketabhängigkeiten im System installiert wurden
[bigdata@bigdata-pro02 ~]$ rpm -qa | grep mysql mysql-libs-5.1.73-3.el6_5.x86_64
Wenn Sie überprüfen, ob einige Installationspakete vorhanden sind, verwenden Sie rpm -e --nodeps [Installationspaket 1 ] [Paket 2 installieren] [...] Deinstallieren Sie das vorhandene Installationspaket.
Sie müssen hier zum Root-Benutzer wechseln
[root@bigdata-pro02 ~]# rpm -e --nodeps mysql-libs-5.1.73-3.el6_5.x86_64 [root@bigdata-pro02 ~]#
2. Überprüfen Sie die verfügbaren Installationspakete auf der Yum-Quelle (wenn Anforderungen für die MySQL-Version bestehen, können Sie die Konfiguration der Yum-Quelle ändern)
Verwenden Sie die Yum-Liste | grep mysql, um das verfügbare Installationspaket zu überprüfen
[root@bigdata-pro02 ~]# yum list | grep mysql-server mysql-server.x86_64 5.1.73-8.el6_8 @base
3. Installieren Sie mysql-server, verwenden Sie den Befehl yum install. Während des Installationsvorgangs werden alle abhängigen Pakete automatisch heruntergeladen und installiert

Überprüfen Sie, ob MySQL im System installiert ist
[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
Überprüfen Sie den Speicherort des MySQL-Befehls
[root@bigdata-pro02 ~]# which mysql /usr/bin/mysql
4. Starten Sie den MySQL-Dienst
[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' **# 以上为两种新建root用户并设置密码的方式** 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 ]
5. Verwenden Sie die MySQL-Datenbank
Fügen Sie den Root-Benutzer hinzu und legen Sie das Passwort fest
[root@bigdata-pro02 ~]# /usr/bin/mysqladmin -u root password '123456'
Melden Sie sich bei der MySQL-Datenbank an
