How to configure nginx log scheduled backup and deletion
一旦开启了nginx日志功能,每天nginx都会生成一定大小的日志文件,如果系统稳定运行,没有任何问题,那么日志基本上不会去查看。但这些日志如不及时清理,日渐积累,对服务器的磁盘空间占用也将是比较恐怖的。为了解决这个问题,利用shell脚本对nginx日志文件定时备份和删除,只保留一段时间。
图1:
#!/bin/bash #auth:lzq #desc:把当前日志按日期备份,重新生成第二天的日志文件 #date:2016-09-18 date=`date +%y%m%d` nginx_pid=`cat /var/run/nginx.pid` #如果当前nginx没有运行就退出 if [ "$?" != 0 ] then exit 1; fi #nginx 日志所在的路径 log_path='/usr/local/nginx/logs/' log_name='access.log' mv ${log_path}${log_name} ${log_path}${log_name}$date #删除7天前旧的备份文件 function deloldbak() { olddate=`date +"%y%m%d" -d "-$1 day"` if [ -e "${log_path}${log_name}$olddate" ] then rm -f ${log_path}${log_name}$olddate echo "${log_path}${log_name}$olddate del ok" fi } #重载nginx配置,重新生成nginx日志文件 kill -usr1 $nginx_pid if [ "$?" == 0 ] then deloldbak 7 exit 0; fi

An important task for Linux administrators is to protect the server from illegal attacks or access. By default, Linux systems come with well-configured firewalls, such as iptables, Uncomplicated Firewall (UFW), ConfigServerSecurityFirewall (CSF), etc., which can prevent a variety of attacks. Any machine connected to the Internet is a potential target for malicious attacks. There is a tool called Fail2Ban that can be used to mitigate illegal access on the server. What is Fail2Ban? Fail2Ban[1] is an intrusion prevention software that protects servers from brute force attacks. It is written in Python programming language

Today, I will lead you to install Nginx in a Linux environment. The Linux system used here is CentOS7.2. Prepare the installation tools 1. Download Nginx from the Nginx official website. The version used here is: 1.13.6.2. Upload the downloaded Nginx to Linux. Here, the /opt/nginx directory is used as an example. Run "tar-zxvfnginx-1.13.6.tar.gz" to decompress. 3.

After yum installs keepalived, configure the keepalived configuration file. Note that in the keepalived configuration files of master and backup, the network card name is the network card name of the current machine. VIP is selected as an available IP. It is usually used in high availability and LAN environments. There are many, so this VIP is an intranet IP in the same network segment as the two machines. If used in an external network environment, it does not matter whether it is on the same network segment, as long as the client can access it. Stop the nginx service and start the keepalived service. You will see that keepalived pulls the nginx service to start. If it cannot start and fails, it is basically a problem with the configuration files and scripts, or a prevention problem.
