In Linux, how does nginx cut access logs?

 

In linux, we can use crontab to regularly move access. log to the backup directory. At the same time, we can signal USR1 to the nginx main process to generate a new log file.

 

Before writing a script, perform the following assumptions:

 

The log file is/usr/local/nginx/logs/access. log.

 

The nginx master process id is saved in the file:/usr/local/nginx/logs/nginx. pid

 

Directory of the backup file after cutting:/usr/local/nginx/logs/bak/

 

For detailed steps of cutting, see the following operations:

 

1. Create the file cut_access_log.sh:

 

 

Vim/. bin/cut_access_log.sh

2. Input File cut_access_log.sh content

 

 

#! /Bin/bash

 

Org_path = "/usr/local/nginx/logs /"

 

Dest_path = "/usr/local/nginx/logs/bak /"

 

 

 

If [! -D "$ dest_path"]; then

 

Mkdir "$ dest_path"

 

Fi

 

 

 

Mv $ {org_path} access. log $ {dest_path} access $ (date + % Y % m % d). log

 

Kill-USR1 'cat/usr/local/nginx/logs/nginx. pid'

3. After saving cut_access_log.sh, grant the executable permission

 

 

 

Chmod + x/. bin/cut_access_log.sh

4. Compile the crontab file:

 

 

 

Vim/. cron

5. Enter the content of the crontab file and keep it

 

 

 

59 23 ***/bin/bash/. bin/cut_access_log.sh

6. Add to crontab

 

 

 

Crontab/. cron

 

 

In the preceding six steps, if you have sufficient permissions, access logs are cut at every day.
