nginx日志切割

利用logrotate进行切割

#创建切割配置
cat > /etc/logrotate.d/nginx <<EOF
/opt/nginx/logs/*.log { 
    daily
    missingok
    rotate 90
    compress
    delaycompress
    notifempty
    create 644 root root
    sharedscripts
    dateext
    dateformat _%Y%m%d
    postrotate
            if [ -f /opt/nginx/logs/nginx.pid ]; then
                    kill -USR1 \`cat /opt/nginx/logs/nginx.pid\`
            fi
    endscript
}
EOF

#/opt/nginx/logs/*.log注意替换为实际路径
#/opt/nginx/logs/nginx.pid注意替换为实际路径
#rotate 90保留90天

创建定时任务

echo "0 0 * * * root bash /usr/sbin/logrotate -f /etc/logrotate.d/nginx" >> /etc/crontab
