指令 service mysql start
出錯,mysql無法啟動,看到mysql: unrecognized service錯誤訊息
遇到的情境如下:
[root@localhost ~]# service mysql start
mysql: unrecognized service
[root@localhost ~]# service mysql restart
mysql: unrecognized service
[root@localhost ~]# rpm -q mysql 查詢發現mysql已經正常安裝
mysql-5.1.52-jason.1
[root@localhost ~]# /etc/rc.d/init.d/mysqld start ----直接啟動沒問題
Starting mysqld: [ OK ]
[root@localhost ~]# ls /etc/rc.d/init.d/mysqld -l
-rwxr-xr-x 1 root root 5509 Dec 18 02:31 /etc/rc.d/init.d/mysqld
[root@localhost ~]# chkconfig mysqld on ----設置mysql開機啟動
[root@localhost ~]# chmod 755 /etc/rc.d/init.d/mysqld ----修改mysqld執行權限
[root@localhost ~]# service mysqld start ----搞定
Starting mysqld: [ OK ]
[root@localhost ~]# service mysqld start
Starting mysqld: [ OK ]
[root@localhost ~]# service mysqld status
mysqld (pid 9487) is running...
