本文目录导读：
在当今互联网高速发展的时代，Nginx作为一款高性能的Web服务器和反向代理服务器，广泛应用于各类网站和服务中，其高效的性能和灵活的配置使其成为众多开发者和运维工程师的首选，随着网站的访问量增加，Nginx生成的日志文件也会迅速膨胀，这不仅会占用大量磁盘空间，还可能影响服务器的性能，合理配置Nginx日志清理显得尤为重要。
Nginx日志简介
Nginx日志主要分为两种：访问日志（access.log）和错误日志（error.log），访问日志记录了每个客户端请求的信息，包括IP地址、请求时间、请求方法、请求URL等；错误日志则记录了服务器运行过程中出现的错误信息。
日志清理的必要性
1、磁盘空间管理：日志文件如果不定期清理，会占用大量磁盘空间，影响服务器的正常运行。
2、性能优化：过多的日志文件会增加磁盘I/O操作，降低服务器性能。
3、数据分析：定期清理过旧的日志，有助于集中精力分析近期数据，提高效率。
日志清理配置方法
1. 使用logrotate工具
logrotate是Linux系统中常用的日志管理工具，可以自动进行日志的轮转、压缩和删除。
配置步骤：
1、编辑logrotate配置文件
logrotate的配置文件位于/etc/logrotate.conf，可以针对Nginx创建一个专门的配置文件，如/etc/logrotate.d/nginx。
```bash
sudo vi /etc/logrotate.d/nginx
```
2、添加配置内容
```bash
/var/log/nginx/*.log {
daily
missingok
rotate 7
compress
postponecompress
compresscmd /bin/gzip
compressoptions -9
nomail
notifempty
create 640 root adm
postponeifempty
su root root
}
```
daily：每天轮转一次日志。
rotate 7：保留7天的日志文件。
compress：轮转后压缩日志文件。
3、执行logrotate
可以手动执行logrotate命令，或者通过cron job定期执行。
```bash
sudo logrotate /etc/logrotate.d/nginx
```
2. 使用Nginx自带的日志切割功能
Nginx 1.9.7及以上版本支持log_format和access_log指令进行日志切割。
配置步骤：
1、编辑Nginx配置文件
通常Nginx的主配置文件位于/etc/nginx/nginx.conf。
```bash
sudo vi /etc/nginx/nginx.conf
```
2、添加日志切割配置
```nginx
http {
log_format main '$remote_addr - $remote_user [$time_local] "$request" '
'$status $body_bytes_sent "$http_referer" '
'"$http_user_agent" "$http_x_forwarded_for"';
access_log /var/log/nginx/access.log main buffer=32k;
access_log /var/log/nginx/access.log main gzip buffer=32k;
}
```
buffer=32k：设置日志缓冲区大小，减少磁盘I/O操作。
gzip：启用日志压缩。
3、重启Nginx
```bash
sudo systemctl restart nginx
```
3. 使用脚本自动清理
可以编写Shell脚本，定期删除过旧的日志文件。
示例脚本：
#!/bin/bash
定义日志保留天数
KEEP_DAYS=7
定义日志目录
LOG_DIR="/var/log/nginx"
删除过旧的日志文件
find $LOG_DIR -type f -name '*.log.*' -mtime +$KEEP_DAYS -exec rm -f {} ;
压缩当前日志文件
gzip -9 $LOG_DIR/*.log
重命名压缩后的日志文件
for file in $LOG_DIR/*.log.gz
do
mv $file $file.date +%Y%m%d.gz
done定时执行脚本：
1、将脚本保存为/usr/local/bin/cleanup_nginx_logs.sh
2、添加执行权限
```bash
sudo chmod +x /usr/local/bin/cleanup_nginx_logs.sh
```
3、编辑cron job
```bash
sudo crontab -e
```
4、添加定时任务
```bash
0 0 * * * /usr/local/bin/cleanup_nginx_logs.sh
```
这表示每天凌晨0点执行一次日志清理脚本。
注意事项
1、备份日志：在清理日志前，建议备份重要日志，以防数据丢失。
2、测试配置：每次修改配置后，应进行测试，确保日志清理操作正常。
3、监控日志：定期监控日志文件大小和生成速度，适时调整清理策略。
合理配置Nginx日志清理，不仅可以有效管理磁盘空间，还能优化服务器性能，提升网站的整体运行效率，通过logrotate工具、Nginx自带的日志切割功能或自定义脚本，可以灵活地实现日志的定期清理和压缩，确保服务器的稳定运行。
