【Nginx】日志切割和定期删除日志

本文日志切割和定期删除日志都是通过定时任务（cron）执行脚本完成

**日志切割脚本**

cut\_nginx\_log\_of\_yesterday.sh

#!/bin/bash
    # program:
    # cut nginx log of yesterday
    source /etc/profile
    
    log_path="/data/logs/nginx/"
    yesterday=$(date -d "yesterday" +"%Y%m%d")
    
    mv ${log_path}error.log ${log_path}error.$yesterday.log
    mv ${log_path}pc_access.log ${log_path}pc_access.$yesterday.log
    
    nginx -s reload

**定期删除脚本**

rm\_nginx\_log.sh

#!/bin/bash
    #program:
    # delete nginx logs of 10 days ago
    find /data/logs/nginx/ -mtime +10 -name "*.log" -exec rm -rf {} \;

**cron 配置文件**

cron.conf 配置以上两个脚本到定时任务

0 0 * * * /bin/bash /opt/script/cut_nginx_log/cut_nginx_log_of_yesterday.sh
    0 16 * * * /bin/bash /opt/script/cut_nginx_log/rm_nginx_log.sh

**脚本上传Nginx服务器并添加定时任务**

本地编写脚本add.sh，把cut\_nginx\_log\_of\_yesterday.sh、rm\_nginx\_log.sh和cron.conf上传到Nginx服务器，并添加定时任务

#!/bin/bash
    #program:
    # add cron to cut nginx log on nginx server
    
    ip_array=(192.168.1.1 192.168.1.2 192.168.1.3)
    
    cron_conf_from_path="/data/scripts/cron_to_cut_nginx/"
    cron_script_from_path="/data/scripts/cron_to_cut_nginx/"
    
    cron_conf_to_path="/opt/conf/cron_to_cut_nginx_log/"
    cron_script_to_path="/opt/script/cut_nginx_log/"
    
    for ip in ${ip_array[@]}
    do
            ssh root@${ip} "mkdir -p ${cron_conf_to_path}"
            scp ${cron_conf_from_path}cron.conf root@${ip}:${cron_conf_to_path}cron.conf
    
            ssh root@${ip} "mkdir -p ${cron_script_to_path}"
            scp ${cron_script_from_path}cut_nginx_log_of_yesterday.sh root@${ip}:${cron_script_to_path}cut_nginx_log_of_yesterday.sh
            scp ${cron_script_from_path}rm_nginx_log.sh root@${ip}:${cron_script_to_path}rm_nginx_log.sh
            ssh root@${ip} "crontab ${cron_conf_to_path}cron.conf"
            echo "${ip}"
            ssh root@${ip} "crontab -l"
    
    done

最后本地执行 sh add.sh就把前面的脚本上传到了nginx服务器上，并且加入了cron定时任务
