spawn-fcgi-watcher

1. 地址

• https://github.com/switch-st/spawn-fcgi-watcher.git

2. 说明

• 在spawn-fcgi的基础上增加监控功能，首次启动成功后，自动拉起之后退出的fcgi进程
• 基于spawn-fcgi 1.6.4开发
• 程序启动线程，捕捉SIGCHLD信号，回收退出的fcgi子进程，并启动新的fcgi进程
• 子进程退出后会输出退出原因(打断子进程的信号)(输出结果包含unusually关键字)
• 程序会将新的子进程PID写入pid文件
• 杀死watcher进程时，会杀死所有子进程
• 欢迎补充。

3. 编译

• ./autogen.sh
• ./configure [--prefix=/path/to/bin]
• make && make install

4. 调用

   switch@switch-pc:cgi-bin$ ./spawn-fcgi-watcher
   Usage: spawn-fcgi [options] [-- <fcgiapp> [fcgi app arguments]]
   
   spawn-fcgi v1.6.4 - spawns FastCGI processes
   
   Options:
   -f <path>      filename of the fcgi-application (deprecated; ignored if
   		<fcgiapp> is given; needs /bin/sh)
   -d <directory> chdir to directory before spawning
   -a <address>   bind to IPv4/IPv6 address (defaults to 0.0.0.0)
   -p <port>      bind to TCP-port
   -s <path>      bind to Unix domain socket
   -M <mode>      change Unix domain socket mode (octal integer, default: allow
   		read+write for user and group as far as umask allows it)
   -C <children>  (PHP only) numbers of childs to spawn (default: not setting
   		the PHP_FCGI_CHILDREN environment variable - PHP defaults to 0)
   -F <children>  number of children to fork (default 1)
   -b <backlog>   backlog to allow on the socket (default 1024)
   -P <path>      name of PID-file for spawned process (ignored in no-fork mode)
   -n             no fork (for daemontools)
   -v             show version
   -?, -h         show this help
   (root only)
   -c <directory> chroot to directory
   -S             create socket before chroot() (default is to create the socket
   		in the chroot)
   -u <user>      change to user-id
   -g <group>     change to group-id (default: primary group of user if -u
   		is given)
   -U <user>      change Unix domain socket owner to user-id
   -G <group>     change Unix domain socket group to group-id

5. 监控脚本

   • script目录下是我在项目中使用的脚本，包括启动服务、停止服务、异常监控脚本。
   • script/Monitor/WatcherMonitor.sh监控spawn-fcgi-watcher进程，随时拉起。
   • script/Monitor/ProcMonitor.sh监控子进程异常退出，并发送邮件。
