一、诉求

        1、linux服务器开启日志功能，并记录10个月的登录

二、操作

1、进入目录

cd /etc

2、编辑配置

vi logrotate.conf

3、复制配置

/var/log/wtmp {
    monthly
    create 0664 root utmp
        minsize 1M
    rotate 10
}

/var/log/btmp {
    missingok
    monthly
    create 0600 root utmp
    rotate 10
}

# 登录日志轮转配置
/var/log/auth.log {
    create 0600 root utmp
    rotate 10
    monthly
    compress
    postrotate
        # 重新启动syslogd以 flush 任何缓存的日志数据
        kill -HUP `cat /var/run/syslogd.pid 2> /dev/null` 2> /dev/null || true
    endscript
}

# /etc/logrotate.d/syslog

/var/log/syslog {
    create 0644 root utmp
    rotate 10
    monthly
    compress
    postrotate
        kill -HUP `cat /var/run/syslogd.pid 2> /dev/null || echo 1` 2> /dev/null || true
    endscript
}
# system-specific logs may be also be configured here.
