logrotate的配置

2019独角兽企业重金招聘Python工程师标准>>>

    今天登录到服务器上进行检查，发现一个问题那就是nginx日志的大小，我通过du -sh查看到nginx日志已经达到几百M了，这个怎么得行呢，再这样下去肯定要出问题。

    我发现这个问题我第一个想到的是日志自动切换功能，下面就来说说日志切换功能的设置吧

    

cat /etc/logrotate.conf    #logrotate全局配置文件
# see "man logrotate" for details
# rotate log files weekly
weekly

# keep 4 weeks worth of backlogs
rotate 4

# create new (empty) log files after rotating old ones
create

# use date as a suffix of the rotated file
dateext

# uncomment this if you want your log files compressed
#compress

# RPM packages drop log rotation information into this directory
include /etc/logrotate.d

# no packages own wtmp and btmp -- we'll rotate them here
/var/log/wtmp {
    monthly
    create 0664 root utmp
        minsize 1M
    rotate 1
}

/var/log/btmp {
    missingok
    monthly
    create 0600 root utmp
    rotate 1
}

# system-specific logs may be also be configured here.
前面的信息都可以不管的看下面我对nginx的配置
cat /etc/logrotate.d/nginx 
/var/log/nginx/*.log {
        daily
        dateext
        minsize 3M
        rotate 5
        create
        postrotate  
        /bin/kill -USR1 `cat /usr/local/nginx/logs/nginx.pid`   > /dev/null 2>/dev/null || true  
        endscript
}

操作的时候可能会出现下面红色的部分，不用担心不是错误
