centos 6.7 搭建tornado + nginx + supervisor的方法（已经实践）

首先，本来不想写这篇博客了，但是我测试了很多网上的例子包括简书的，全不行，我总结原因是自己太笨，搞了俩个晚上，后来决定，自己还是写一篇记录下来，保证自己以后使用

 环境：

　　centos6.7 64

　　python2.7.11

　　pip 9.0.1

　　nginx1.4.5

1.安装nginx

nginx安装方法

[root@pythonS1 ~]# vim /usr/local/nginx1.4.5/conf/nginx.conf
user nginx;
worker_processes 5;



events {
    worker_connections 1024;
    use epoll;
}

http{
upstream tornadoes {
    server 127.0.0.1:8000;
    server 127.0.0.1:8001;
    server 127.0.0.1:8002;
    server 127.0.0.1:8003;
}

server {
    listen 80;
    server_name localhost;

    location /static/ {
        root /var/www/static;
        if ($query_string) {
            expires max;
        }
    }

    location / {
        proxy_pass_header Server;
        proxy_set_header Host $http_host;
        proxy_redirect off;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Scheme $scheme;
        proxy_pass http://tornadoes;
        #proxy_pass http://www.iyunv.com/;
    }
}
}

 

2.tornado的代码

我把自己的代码放在了/opt/pythonweb下面

3.supervisor安装和使用

启动supervisor的时候报错pkg_resources.DistributionNotFound: meld3>=0.6.5

Traceback (most recent call last):
  File "/usr/bin/echo_supervisord_conf", line 5, in <module>
    from pkg_resources import load_entry_point
  File "/usr/lib/python2.6/site-packages/setuptools-0.6c11-py2.6.egg/pkg_resources.py", line 2603, in <module>
  File "/usr/lib/python2.6/site-packages/setuptools-0.6c11-py2.6.egg/pkg_resources.py", line 666, in require
  File "/usr/lib/python2.6/site-packages/setuptools-0.6c11-py2.6.egg/pkg_resources.py", line 565, in resolve
pkg_resources.DistributionNotFound: meld3>=0.6.5

解决方法：pip安装的meld3不可用，手动安装。

wget https://pypi.python.org/packages/source/m/meld3/meld3-1.0.2.tar.gz
tar -zxf meld3-1.0.2.tar.gz
cd meld3-1.0.2
python setup.py install

生成配置文件

echo_supervisord_conf > /etc/supervisord.conf

配置文件最后添加的内容,注意没有user会报错的

启动服务

/usr/local/nginx1.4.5/sbin/nginx

supervisorctl

start all

 4.监控多个进程服务，监控nginx， celery等

 

[program:python]
command=python /opt/pythonweb/hello.py
directory=/opt/pythonweb
autostart=true                ; start at supervisord start (default: true)
startretries=3                ; max # of serial start failures when starting (default 3)
autorestart=true              ; when to restart if exited after running (def: unexpected)
redirect_stderr=true          ; redirect proc stderr to stdout (default false)
stdout_logfile=/var/log/nginx.log        ; stdout log path, NONE for none; default AUTO
stdout_logfile_maxbytes=1MB   ; max # logfile bytes b4 rotation (default 50MB)
stdout_logfile_backups=10     ; # of stdout logfile backups (default 10)
stdout_capture_maxbytes=1MB   ; number of bytes in 'capturemode' (default 0)
stdout_events_enabled=false   ; emit events on stdout writes (default false)
stderr_logfile=/var/log/nginx_err.log        ; stderr log path, NONE for none; default AUTO
stderr_logfile_maxbytes=1MB   ; max # logfile bytes b4 rotation (default 50MB)
stderr_logfile_backups=10     ; # of stderr logfile backups (default 10)
stderr_capture_maxbytes=1MB   ; number of bytes in 'capturemode' (default 0)
stderr_events_enabled=false   ; emit events on stderr writes (default false)
user=root

supervisorctl start nginx  # 启动 nginx
supervisorctl start all    # 启动所有进程
supervisorctl status       # 查看进程状态

 5.注意每次更新完supervisor以后一定要重启supervisor，ps -ef | grep supervisor ,,,kill
