4.日志管理

4.1 日志的格式

    server的访问日志文件为： logs/access.log
    server的错误日志为：logs/error.log
    使用的格式为“main”格式
    除此之外,可以自定义其他格式

4.2 main日志格式

    log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
                         '$status $body_bytes_sent "$http_referer" '
                     '"$http_user_agent" "$http_x_forwarded_for"'; 

4.3 为某一个server使用main格式日志的配置

    首先，打开log_format
    然后：
    server {
        listen 80;
        server_name localhost;
        location / {
            root html;
            index index.html;
        }
        access_log logs/zijide.access.log main;
    }

4.4 日志的定时任务日志切割

4.4.1 书写shell脚本,logs.sh

    LOGPATH=/application/nginx/logs/access.log #日志文件位置
    BASEPATH=/data   #分割文件存储目录
    bak=$BASEPATH/$(date -d yesterday +%Y%m%d%H%M).zcom.access.log #目标文件路径加文件名称     


    mv $LOGPATH $bak  #将源文件移动至目标文件

    touch $LOGPATH  #新建一个文件

    kill -USER1 /application/nginx/logs/nginx.pid  #通知nginx读取新文件

4.4.2编辑定时任务，触发时间

    使用命令：crontab -e

    */1 * * * * sh /application/shellScript/logs.sh #为了测试方便 一分钟执行一次
