Tornado using Supervisor management process, using Nginx for load balancing

Tornado using Supervisor management process, using Nginx for load balancing

Deployment method

Use Nginx as Load Banlancer

nginx的配置文件如下，放在/etc/nginx/sites-avaiable/下，然后再sites-enable下面创建软连接nginx有一个基础配置会include sites-enable下的文件。以下代码是被配置的http{}部分所includeupstream detect_data_server {server 127.0.0.1:8001;server 127.0.0.1:8002;server 127.0.0.1:8003;server 127.0.0.1:8004;}# Only retry if there was a communication error, not a timeout# on the Tornado server (to avoid propagating "queries of death"# to all frontends)# proxy_next_upstream error;  # this has been in nginx.confserver {    listen 80;    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://detect_data_server;    }}

To run the command:

sudo cp /home/opsys/running/detect-datacollect-server/deploy/detect-datacollect-server.conf     /etc/nginx/sites-availablesudo ln -s /etc/nginx/sites-available/detect-datacollect-server.conf     /etc/nginx/sites-enabled/detect-datacollect-server.confsudo service nginx start

Attention:

• When you start Nginx, note the default under the Sites-available directory, and do not include this file in nginx.conf.
• Different system corresponding to the directory is not the same, pay attention to

Using Supervisor for Management

安装supervisor最好用apt-get install 安装放在/etc/supervisor/conf.d/目录下面。和nginx一样，supervisor也有一个基础配置为/etc/supervisor/supervisord.conf，这个文件会去include conf.d中的文件以下为配置：; To take advantage of multiple cores, you'll need multiple processes.[group:gp_detect_data]programs=detect_data[program:detect_data]; envir  ; TEST for test environ. command=python /home/opsys/running/detect-datacollect-server/code/app.py --port=80%(process_num)02dprocess_name = %(program_name)s%(process_num)dautorestart=trueredirect_stderr=truestdout_logfile=/home/opsys/log/detect-data-stdout.logstdout_logfile_maxbytes=50MBstdout_logfile_backups=10stderr_logfile=/home/opsys/log/detect-data-stderr.logloglevel=infonumprocs = 4numprocs_start = 1

To run the command:

sudo cp /home/opsys/running/detect-datacollect-server/conf/supervisor/detect_data.conf    /etc/supervisor/conf.d/sudo service supervisor start

Log directory

Depends on the configuration in the configuration file

• Program Log:/home/opsys/log/detect-data-stdout.log
• Log of Supervisor:/var/log/supervisor/supervisord.log
• Nginx log:/var/log/nginx/

The above describes the tornado use of Supervisor management process, using Nginx to do load balancing, including aspects of the content, I hope that the PHP tutorial interested in a friend helpful.
