在運維或者開發(fā)過程中，經常會遇見部署各類LNMP或者LAMP模式的系統(tǒng)運行架構，尤其再部署數據庫時，往往有人對數據庫使用過程倒是很多，但從頭部署的情況少有發(fā)生，今天推薦一種簡單的mysql安裝操作：這簡單是真正的簡單

?

簡單的解決方案：

?

1、yum源安裝

#yum install #下載及安裝yum源 #yum clean all #清理yum #yum makecache #重新緩存 #yum install mysql-community-server #yum安裝 就這么簡單

2、開啟服務

#/etc/init.d/mysqld

3、查找初始密碼并修改

#grep 'temporary password' /var/log/mysqld.log #唯一不同的就是此處，安裝完成后會有一個初始密碼放置到log中，進行初始登錄 # grep 'temporary password' /var/log/mysqld.log 2018-07-27T11:00:07.016171Z 1 [Note] A temporary password is generated for root@localhost: xxxxx # mysql -uroot -p Enter password: Welcome to the MySQL monitor.

Type '\c' to clear the current input statement. mysql> #強制修改密碼，否則無法使用。 mysql> show databases; ERROR 1820 (HY000): You must reset your password using ALTER USER statement before executing this statement. mysql> set password=password('test123'); #密碼復雜度要求。 ERROR 1819 (HY000): Your password does not satisfy the current policy requirements #復雜度提高后成功。 mysql> set password=password('Test@!234'); Query OK, 0 rows affected, 1 warning (0.00 sec)

4、yum安裝過程中的會出現(xiàn)依賴程序問題，只需要先安裝一下依賴即可

#yum install mysql-devel

通過以上簡單安裝步驟即可完成一鍵部署操作（需要整理方可成一鍵）
