linux自动启动mysql的方法

linux自动启动mysql的方法http://www.bieryun.com/3225.html

最简单的方法,直接编辑/etc/rc.local配置文件
先直接关闭现在启动的mysqld服务
msyqladmin -uroot -p -S /tmp/mysql.3306.sock shutdown
重启机器测试查看:shutdown -r now
ps -ef | grep mysql
[root@localhost ~]# ps -ef | grep mysql
root 1942 1 0 12:29 ? 00:00:00 /bin/sh /usr/bin/mysqld_safe –datadir=/var/lib/mysql –socket=/var/lib/mysql/mysql.sock –pid-file=/var/run/mysqld/mysqld.pid –basedir=/usr –user=mysql
mysql 2026 1942 0 12:29 ? 00:00:00 /usr/libexec/mysqld –basedir=/usr –datadir=/var/lib/mysql –user=mysql –log-error=/var/lib/mysql/localhost.localdomain.err –pid-file=/var/run/mysqld/mysqld.pid –socket=/var/lib/mysql/mysql.sock
root 2319 2263 0 12:31 pts/0 00:00:00 grep mysql
这是系统启动mysql服务的后台程序
于是把这些关掉
chkconfig mysqld off
[root@localhost ~]# chkconfig | grep mysqld
mysqld 0:off 1:off 2:off 3:off 4:off 5:off 6:off
再重启后就ps 就没查到默认启动的错误mysql进程了。
编辑/etc/rc.local文件:
[root@localhost ~]# cat /etc/rc.local
#!/bin/sh
#
# This script will be executed *after* all the other init scripts.
# You can put your own initialization stuff in here if you don’t
# want to do the full Sys V style init stuff.
touch /var/lock/subsys/local
/usr/local/mysql/bin/mysqld_safe –defaults-file=/etc/my.3306.cnf –user=mysql &
[root@localhost ~]#
重启查看生效。可以正常登陆:
[c:\~]$ ssh 192.168.125.128
Connecting to 192.168.125.128:22…
Connection established.
To escape to local shell, press ‘Ctrl+Alt+]’.
