一个nginx的控制脚本，运行在CentOS Linux系统上，使用良好。代码如下：
#!/bin/bash
# master process
# TERM,INT  shutdown fast
# QUIT         shutdown graceful
# HUP           reload config
# USR1          reopen log file
# USR2          update nginx bin file graceful
# WINCH       shutdown worke prcess graceful
# work process
# TERM,INT   shutdown fast
# QUIT          shutdown graceful
# USR1          reopen log file
