我想让脚本睡200秒才能启动达罗拉迪斯。 这是我尝试过的命令，但似乎不工作。
start on login-session-start script sleep 200000 exec > freeradius -X end script
要么
start on login-session-start script sleep 200000 freeradius -X end script
和脚本我保存为etc/init/VPN.conf
这是你的问题：
Mon Jul 28 14:30:29 2014 : Error: rlm_sql_mysql: Mysql error 'Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2)'
这（2）意味着No such file or directory ，即sockets不存在。
你真的安装了MySQL服务器吗？
sudo apt-get install mysql-server
你有没有启动服务器？
sudo service mysql restart
为什么不把（/ bin / sleep 200 && / path / to / freeradius -X）放在/etc/rc.local中？

Ps：睡眠function使用秒。
