操作如下，登陆SSH:
1 | vi /etc/sysconfig/network-scripts/ifcfg-eth0:0 |
第二个IP,就是
1 | vi /etc/sysconfig/network-scripts/ifcfg-eth0:1 |
第三个IP,就是
ifcfg-eth0:2(由此类推)

Linux命令tar压缩排除指定目录的方法
例如我要压缩 /cat/backup 这个文件夹 (绝对路径),但是不将里面的图片文件夹img也压缩了.可以用tar命令的–exclude 排除掉.方法
1 | tar -zcvf backup.tar.gz --exclude=/cat/backup/img /cat/backup |
排除多个目录
1 | tar -zcvf backup.tar.gz --exclude=/cat/backup/img --exclude=/cat/backup/a --exclude=/cat/backup/b /cat/backup |
iptables限制同一IP连接数
最近无聊人太多了,一直拿我的小博客来压力测试,所以不得不限制同一个IP的连接数,用iptables就可以简单设置了…
1 | iptables -I INPUT -p tcp --dport 80 -m connlimit --connlimit-above 10 -j DROP |
限制单个地址并发连接数不大于10
Linux下替换文件名中的空格
1 2 3 4 5 6 7 | find . -type f -name "* *" -print | while read name; do na=$(echo $name | tr ' ' '_') if [[ $name != $na ]]; then mv "$name" $na fi done |
利用功夫网来防止来自中国的DDOS攻击
功夫网终于有贡献了..
不过可能会有副作用,就是连自己的网站都给功夫网封了…
下面是php代码..
1 2 3 4 5 6 | <?php if(strpos($_SERVER['REQUEST_URI'],'minghui') === false) { header('Location:'. $_SERVER['REQUEST_URI'] . '?minghui'); exit; } ?> |
