一段linux启动脚本(python版)

作者: fred 日期: 2011 年 2 月 21 日没有评论

公司项目用到需要开机自动执行相关程序，奈何shell不是很精通，老大给了段python版的，我也分享下，供大家参考

#!/usr/bin/env python

# init.d script for the Mytut CS Repo Server; John Wang 14 Feb 2011

import sys,subprocess,time

cmmd    = '/home/fred/test.py'#启动/关闭执行命令

port    = '12600'

decp    = 'start process program....'

cmmdln  = ['nohup',cmmd,'-p',port]

def start():

print 'Starting %s...' % decp

subprocess.Popen(cmmdln)

print 'Started'

def stop():

print 'Stopping %s...' % decp

subprocess.Popen(cmmdln)

print 'Stopped'

return 0

def restart():

if stop()==1:

print 'Stopping error. Maybe already stopped ?. starting anyway ...'

else:

time.sleep(1)

start()

def run(argv):

fns={

    'start':start,

    'stop':stop,

    'restart':restart,

    'reload':restart,

}

fn=fns.get(argv[1],None) if len(argv)&gt;1 else None

if not fn:

print &gt;&gt; sys.stderr,"Usage: %s {%s}" % (argv[0],'|'.join(fns.keys()))

sys.exit()

fn()

if __name__ == '__main__':

run(sys.argv)

#!/usr/bin/env python

# init.d script for the Mytut CS Repo Server; John Wang 14 Feb 2011

import sys,subprocess,time

cmmd = '/home/fred/test.py'#启动/关闭执行命令

port = '12600'

decp = 'start process program....'

cmmdln = ['nohup',cmmd,'-p',port]

def start():

print 'Starting %s...' % decp

subprocess.Popen(cmmdln)

print 'Started'

def stop():

print 'Stopping %s...' % decp

subprocess.Popen(cmmdln)

print 'Stopped'

return 0

def restart():

if stop()==1:

print 'Stopping error. Maybe already stopped ?. starting anyway ...'

else:

time.sleep(1)

start()

def run(argv):

fns={

'start':start,

'stop':stop,

'restart':restart,

'reload':restart,

}

fn=fns.get(argv[1],None) if len(argv)>1 else None

if not fn:

print >> sys.stderr,"Usage: %s {%s}" % (argv[0],'|'.join(fns.keys()))

sys.exit()

fn()

if __name__ == '__main__':

run(sys.argv)

比较简单~

前文介绍过,放在/etc/rc3.d 目录下即可,linux启动后会自动执行这个目录里面的脚本,默认使用start参数启动

一段不错的PRE样式

从网上找的,忘了作者链接,若作者看到此文,请留言链接,我将补上

                PRE {

                overflow: auto;

                overflow-y: hidden;

                background-color: grey;

                font-size: 12px;

                width: 95%;

                line-height: 16px;

                font-family: "Courier New", FixedSys;

                color: #555;

                background: #fafafa;

                border-top: 1px solid #ccc;

                border-bottom: 1px solid #ccc;

                border-left: 15px solid #ccc;

                border-right: 1px solid #ccc;

                padding: 0 5px;

                margin: 0 0 20px;

                }

PRE {

overflow: auto;

overflow-y: hidden;

background-color: grey;

font-size: 12px;

width: 95%;

line-height: 16px;

font-family: "Courier New", FixedSys;

color: #555;

background: #fafafa;

border-top: 1px solid #ccc;

border-bottom: 1px solid #ccc;

border-left: 15px solid #ccc;

border-right: 1px solid #ccc;

padding: 0 5px;

margin: 0 0 20px;

}

效果看此处即可

nginx反向代理(ghs.google.com)

作者: fred 日期: 2011 年 2 月 14 日没有评论

设置ghs.google.com代理

                upstream ghs {

                ip_hash;

                server ghs.google.com;

                server 72.14.203.121;

                server 72.14.207.121;

                server 74.125.43.121;

                server 216.239.34.21;

                server 216.239.36.21;

                }

                server {

                listen 80;

                server_name www.fengsage.com;

                location / {

                proxy_set_header Host $host;

                proxy_pass http://ghs;

                proxy_set_header X-Real-IP  $remote_addr;

                proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

                }

                }

                }

upstream ghs {

ip_hash;

server ghs.google.com;

server 72.14.203.121;

proxy_set_header Host $host;

proxy_pass http://ghs;

proxy_set_header X-Real-IP $remote_addr;

proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

}

                upstream 设置轮询服务IP,其实设置一个ghs.google.com就可以了,因为本身就是googleCDNS网络

Linux自动运行脚本

作者: fred 日期: 2011 年 2 月 13 日没有评论

windows下开机启动某个程序比较简单,只需要把程序添加到”程序-启动”栏即可.

对于linux下开机自动运行程序笔记麻烦. 以Apache Tomcat为例. 做开机自动启动

                SERVICE_HOME="/home/tomcat"

                SERVICE_DESC="Apache Tomcat"

                SERVICE_USER="tomcat"

                CONSOLE_LOG="$SERVICE_HOME/console.log"

                START_SCRIPT="startup.sh"

                SHUTDOWN_SCRIPT="shutdown.sh"

                start(){

                echo "Starting $SERVICE_DESC Server ..."

                cd $SERVICE_HOME/bin

                sudo -u $SERVICE_USER ./$START_SCRIPT > $CONSOLE_LOG 2> $CONSOLE_LOG &

                }

                stop(){

                echo "Stopping $SERVICE_DESC Server ... "

                cd $SERVICE_HOME/bin

                sudo -u $SERVICE_USER ./$SHUTDOWN_SCRIPT > $CONSOLE_LOG 2> $CONSOLE_LOG &

                }

                restart(){

                stop

                # give stuff some time to stop before we restart

                sleep 5s

                start

                }

                case "$1" in

                start)

                start

                ;;

                stop)

                stop

                ;;

                restart)

                restart

                ;;

                *)

                echo "Usage: tomcat {start|stop|restart}"

                exit 1

                esac

                exit 0

SERVICE_HOME="/home/tomcat"

SERVICE_DESC="Apache Tomcat"

SERVICE_USER="tomcat"

CONSOLE_LOG="$SERVICE_HOME/console.log"

START_SCRIPT="startup.sh"

SHUTDOWN_SCRIPT="shutdown.sh"

start(){

echo "Starting $SERVICE_DESC Server ..."

cd $SERVICE_HOME/bin

sudo -u $SERVICE_USER ./$START_SCRIPT > $CONSOLE_LOG 2> $CONSOLE_LOG &

}

stop(){

echo "Stopping $SERVICE_DESC Server ... "

cd $SERVICE_HOME/bin

sudo -u $SERVICE_USER ./$SHUTDOWN_SCRIPT > $CONSOLE_LOG 2> $CONSOLE_LOG &

}

restart(){

stop

# give stuff some time to stop before we restart

sleep 5s

start

}

case "$1" in

start)

start

;;

stop)

stop

;;

restart)

restart

;;

echo "Usage: tomcat {start|stop|restart}"

exit 1

esac

exit 0

设置：

1、保存脚本到/ect/init.d/目录下，保存名tomcat.sh

2、进入/etc/rc3.d/目录,新建一个软链接 sudo ln -s ../init.d/tomcat.sh tomcat

注：ect目录下有很多rc1.d、rc2.d….这类的目录,这里是linux用来设置不同程序启动顺序用,数字越小启动优先级越高,一般而言我们自己的程序放在rc3.d目录下即可
