For compiled and installed Nginx, You can compile and install the new version to the nginx installation path of the old version. before replacement, it is best to back up the old executable program
• Send the following commands:
Kill USR2 <nginx master process Number of the old version>
• The Old Master process will rename its pid file. oldbin (for example,/usr/local/nginx/logs/nginx. pid. and then execute the new version of the nginx executable program, start the new main process and the new Working Process in turn.
• The nginx instances of the new and old versions run simultaneously to process input requests. to gradually stop an earlier version of nginx instance, you must send a WINCH signal to the old master process. Then, its working process will start to be closed with ease:
Kill WINCH <Nginx master process Number of the old version>
• After a period of time, the old worker process processes all connected requests and then exits. Only the new worker process processes the input requests.
• At this time, we can decide whether to use the new version or reply to the old version;
Kill HUP <old master process number>: Nginx starts the working process without reloading the configuration file;
Kill QUIT <new master process number>: Shut down other worker processes normally (woker process );
If an error is reported, the following command is used to shut down the old working process before closing the master process Number:
Kill TERM <new worker process number>: force quit worker process;
Kill <new master process number or old master process number>: if a new worker process cannot exit for some reason, it sends a kill signal to it.
After the new master process exits, the old master process will be removed. the oldbin prefix. pid file. In this way, everything will be restored before the upgrade. If the upgrade is successful and you want to keep the new server, you can send a QUIT signal to the old master process, leave the server to run. 6. log cutting mv/data1/logs/access. log/data1/logs/20160520.log
Kill-USR1 'cat/var/run/nginx. Pi' # in this way, you do not need to use ps to find the Nginx main process number.

If you want it to regularly cut logs every day, you can write a shell script and use crontab to regularly run logs every day.

#! /Bin/bash
# Define the path for storing Nginx log files
Logs_path = "/var/logs/nginx /"

Mkdir-p $ {logs_path} $ (date-d "yesterday" + "% Y")/$ (date-d "yesterday" + "% m ")/
Mv $ {logs_path} access. log $ {logs_path} $ (date-d "yesterday" + "% Y")/$ (date-d "yesterday" + "% m ") /access _ $ (date-d "yesterday" + "% Y % m % d "). log
Kill-USR1 'cat/var/run/nginx. Pi'

Configure crontab and enter crontab-e.
Input:
00 00 ***/bin/bash/usr/loca/webserver/nginx/sbin/cut_nginx_log.sh
