CentOS 6.6安装配置supervisor进程管理工具
1. Supervisor是一个C/S系统,它可以在类unix操作系统让用户来监视和控制后台服务进程的数量，一个很重要的功能就是监控服务器的主要后台进程，并在出现问题是自动重启。

2. 根据服务器上的python版本下载对应的setuptools

[root@test1 ~]# python -V

Python 2.6.6

1. wget http://pypi.python.org/packages/2.6/s/setuptools/setuptools-0.6c11-py2.6.egg

复制代码

直接安装

sh setuptools-0.6c11-py2.6.egg

3. 下载并安装supervisor

1. wget http://pypi.python.org/packages/source/s/supervisor/supervisor-3.0b1.tar.gz
   
2. tar -zxvf supervisor-3.0b1.tar.gz
   
3. cd supervisor-3.0b1
   
4. python setup.py install

复制代码

安装setuptools后也可以

easy_install supervisor

4. 设定supervisor配置文件

创建默认的配置文件

echo_supervisord_conf  >/etc/supervisord.conf

vi /etc/supervisord.conf

取消以下的注释,并修改IP为0.0.0.0

[inet_http_server]        ; inet (TCP) server disabled by defaultport=0.0.0.0:9001        ; (ip_address:port specifier, *:port for all iface)username=user              ; (default is no username (open server))password=123              ; (default is no password (open server))

增加自定义的后台进程(注意进程名之间用一个:分隔)

[program:hello]command=python /root/hello.pypriority=1numprocs=1autostart=trueautorestart=truestartretries=10stopsignal=KILLstopwaitsecs=10redirect_stderr=truestdout_logfile=/root/hello.log


5. 执行如下命令：

vi /etc/init.d/supervisord

6.输入如下内容：

注意：该文件中的如下几个变量，都需要根据你实际的目录来改写。

PREFIX=/usr/local

SUPERVISORD=$PREFIX/bin/supervisord      ##supervisord   程序的安装路径

SUPERVISORCTL=$PREFIX/bin/supervisorctl  ##supervisorctl 程序的安装路径

复制代码

保存完毕之后，可以执行以下命令修改文件权限：

chmod 777 /etc/init.d/supervisord

/etc/init.d/supervisord  start

这样，supervisor就启动了。

7. 配置开机启动

执行以下命令：

chkconfig supervisord  on

可以以下命令查看是否成功

chkconfig --list | grep  supervisord
