這篇文章主要為大家詳細介紹了CentOS 7下mysql 5.7.18 安裝配置方法圖文教程，具有一定的參考價值，有興趣的小伙伴們可以參考一下
介紹如何在Linux下方安裝MySQL 5.7.18
1、下載MySQL：官網www.mysql.com/，點選Downlosas，翻到網頁底部，下載社群版，一路點下去，選擇通用Linux，下載64位那個，注意檢查MD5
值。
2、安裝關鍵步驟，直接貼出指令

一行一行解釋：
第一步，bin/mysqld 注意後面給的參數，之一部會產生一個臨時密碼，保存，後面登入資料庫要用到；
第二步，bin/mysql_ssl_rsa_setup，看起來像是對資料庫安全性的處理，注意後面給的參數。
/etc/init.d/mysqld 下，主要負責MySQL的開機啟動。
/mysql/bin/mysqld_safe、/mysql/bin/mysqld
#登入mysql，修改暫存密碼：/usr/local/mysql/bin/mysql -u root -p 回車輸入初始化時產生的暫存密碼，修改密碼：
'root'@localhost=password('xxxxxx');
每次登入mysql客戶端嫌輸絕對路徑麻煩，就建一個軟連接：ln -s /usr/local/mysql/bin/mysql /usr/bin/mysql,這樣也省去了配PATH路徑的麻煩。
mysqld的開機啟動，使用chkconfig指令
chkconfig --add mysqld #增加mysqld服务 chkconfig --list #列出所有的系统服务
看一下是不是在所有等級都是開啟狀態，例如：
chkconfig --level 35 mysqld on #设定mysqld在等级3和5为开机运行服务
