RHEL / CentOS / Fedora 安裝 MySQL 5.7

如果是在Ubuntu 會簡單一點點，直接下

sudo apt install mysql-server

首先需要有 wget 或 curl 指令：

yum install wget

---

加入 MySQL Yum Repository
根據不同的發行版下載相應的 RPM 及安裝:

RHEL 7, CentOS 7:

wget http://dev.mysql.com/get/mysql57-community-release-el7-7.noarch.rpm
yum localinstall mysql57-community-release-el7-7.noarch.rpm

RHEL 6, CentOS 6:

wget http://dev.mysql.com/get/mysql57-community-release-el6-7.noarch.rpm
yum localinstall mysql57-community-release-el6-7.noarch.rpm

Fedora 23:

wget http://dev.mysql.com/get/mysql57-community-release-fc23-7.noarch.rpm
dnf localinstall mysql57-community-release-fc23-7.noarch.rpm

Fedora 22:

wget http://dev.mysql.com/get/mysql57-community-release-fc22-7.noarch.rpm
dnf localinstall mysql57-community-release-fc22-7.noarch.rpm

安裝 MySQL

啟用了 MySQL 的 YUM Repository 後, 可以用 yum 或 dnf 安裝 MySQL 最新版, 目前最新版是 MySQL 5.7:

RHEL, CentOS:

yum install mysql-community-server

Fedora:

dnf install mysql-community-server

查看服務的裝態：

systemctl status mysql

mysql.service - MySQL Community Server
   Loaded: loaded (/lib/systemd/system/mysql.service; enabled; vendor preset: enabled)
   Active: active (running) since Thu 2018-07-12 17:46:42 UTC; 17s ago
     Docs: man:mysqld(8)
           http://dev.mysql.com/doc/refman/en/using-systemd.html
 Main PID: 7918 (mysqld)
   Status: "SERVER_OPERATING"
    Tasks: 37 (limit: 1152)
   CGroup: /system.slice/mysql.service
           └─7918 /usr/sbin/mysqld

Active: active (running)

---

啟動 MySQL:

service mysqld start

或

service mysql start

說明：使用ubuntu 安裝 mysql-server ，service name 會是 mysql 而不是 mysqld。
