CentOS7安裝MySQL Server
CentOS 7的默認YUM源中是MariaDB,而不是我們常用的MySQL。
本文將介紹如何通過YUM安裝MySQL。
- 首先下載Yum源的rpm包
具體地址在:
http://repo.mysql.com/
可以選擇自己需要的版本。
我下載的是:
wget http://repo.mysql.com/mysql57-community-release-el7.rpm
- 安裝rpm文件
通過命令,安裝MySQL的YUM源:
rpm -ivh mysql57-community-release-el7.rpm
可以在/etc/yum.repos.d中看到相關的repo文件:
[[email protected]
CentOS-Base.repo CentOS-Debuginfo.repo CentOS-Media.repo CentOS-Vault.repo mysql-community-source.repo
CentOS-CR.repo CentOS-fasttrack.repo CentOS-Sources.repo mysql-community.repo OpenLogic.repo
[[email protected] yum.repos.d]#
- YUM安裝MySQL
通過yum命令安裝:
yum install -y mysql-server
- 啟動MySQL
啟動:
Systemctl start mysqld
查看:
Systemctl status mysqld
設置開機啟動:
Systemctl enable mysqld
通過netstat查看:
[[email protected] yum.repos.d]# netstat -tunlp

可以看到3306端口。
