为mysql-proxy提供SysV服务脚本，内容如下所示
# vim /etc/rc.d/init.d/mysql-proxy

#!/bin/bash

#

# mysql-proxy Thisscript starts and stops the mysql-proxy daemon

#

# chkconfig: - 7830

# processname:mysql-proxy

echo

if [ $RETVAL -eq 0 ]; then

touch /var/lock/subsys/mysql-proxy

fi

}

stop() {

echo -n $"Stopping $prog: "

killproc -p $PROXY_PID -d 3 $prog

RETVAL=$?

echo

if [ $RETVAL -eq 0 ]; then

将上述内容保存为/etc/rc.d/init.d/mysql-proxy，给予执行权限，而后加入到服务列表。

# chmod +x /etc/rc.d/init.d/mysql-proxy

# chkconfig --add mysql-proxy
