tornado 使用supervisor管理進程，使用nginx做負載平衡

部署方式

採用nginx作為load banlancer

nginx的設定檔如下，放在/etc/nginx/sites-avaiable/下，然後再sites-enable下面建立軟串連nginx有一個基礎配置會include sites-enable下的檔案。以下代碼是被配置的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;    }}

運行命令：

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

注意：

• 啟動nginx時要注意sites-available目錄下面的default，在nginx.conf中不要include了這個檔案
• 不同的系統對應的目錄不一樣，要注意

使用supervisor進行管理

安裝supervisor最好用apt-get install 安裝放在/etc/supervisor/conf.d/目錄下面。和nginx一樣，supervisor也有一個基礎配置為/etc/supervisor/supervisord.conf，這個檔案會去include conf.d中的檔案以下為配置：; 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

運行命令：

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

log目錄

具體的要看設定檔中的配置

• 程式log：/home/opsys/log/detect-data-stdout.log
• supervisor的log: /var/log/supervisor/supervisord.log
• nginx log：/var/log/nginx/
