Log cutting

Below is the log splitting script

#!/bin/bash
day=$(date -d "-1 day" "+%Y%m%d")
logs_path="/var/log/nginx"
pid_path="/usr/local/nginx/logs/nginx.pid"
[ -d $logs_path ] || mkdir -p $logs_path
mv /usr/local/nginx/logs/access.log ${logs_path}/access.log-$day
kill -USR1 $(cat $pid_path)
find $logs_path -mtime +30 -exec rm -rf {} \;

#### Use the log segmentation script to automatically segment the log every day chmod +x /opt/jiaoben.sh
crontab -e
0 1 * * * /opt/jiaoben.sh

Achieving high concurrency by changing the number of CPU cores

### Check the number of CPUs cat /proc/cpuinfo | grep -c "physical id"
### Change the configuration file. The number of cores needs to correspond to your computer. vim conf/nginx.conf
### After setting, you need to restart the service.

optimization

This can be optimized by the following code

vim /usr/local/php/etc/php-fpm.d/www.conf
--96 lines--
pm = dynamic #fpm process startup mode, dynamic --107 lines--
pm.max_children=20 #The maximum number of processes started by the fpm process--112 lines--
pm.start_servers = 5 #The default number of processes started when starting in dynamic mode is between the minimum and maximum --117 lines--
pm.min_spare_servers = 2 #Minimum number of idle processes in dynamic mode --122 lines--
pm.max_spare_servers = 8 #Maximum number of idle processes in dynamic mode kill -USR2 `cat /usr/local/php/var/run/php-fpm.pid` #Restart php-fpm
netstat -anpt | grep 9000
