yum方式安装mysql省去了源代码包安装的许多步骤,但是有时会遇见mysql yum包装完mysql之后,在启动mysql服务时,启动不了的问题,报错: Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2),找不到mysql.sock文件,mysql.sock文件是安装mysql之后初始化数据库之后才会出现的,因此在安装完包之后,做一下步骤:
添加 mysqld 服务。
/sbin/chkconfig –-add mysqld [在服务清单中添加mysql服务]
接着开始启动mysql。
service mysqld start;(即/etc/init.d/mysqld start。也可设成开机自启动:/sbin/chkconfig mysqld on)
然后,额。。。出现 “MySQL Daemon failed to start”的信息,怎么办?自己是这样解决的。
1. 初始化数据库
/usr/bin/mysql_install_db --user=mysql
cp /usr/share/mysql/my-small.cnf /etc/my.cnf(可选)
2. 以safe方式登录mysql
cd /usr ;
/usr/bin/mysqld_safe &
3. 再次启动mysqld服务时就可以了。
