  shutdown -h now halt  

  shutdown -h now reboot  

  /usr/local/bin/memcached -d -m 10  -u root -l 127.0.0.1 -p 11211 -c 256 -P /tmp/memcached.pid  

  kill `cat /tmp/memcached.pid`

  freebsd 系统状态查看  

  用以下方法检查系统状态：  

     1. Top  

     2. netstat -m  

     3. pstat -T  

     4. systat -if 1  

     5. q  

   kill -HUP 1  

  /etc/rc.d/sshd restart  

  tail /var/log/messages  

  portsnap fetch extract  第一次更新时用  

  portsnap fetch update  以后更新时使用  

  FETCH_CMD=axel  

  FETCH_BEFORE_ARGS= -n 10 -a  

  FETCH_AFTER_ARGS=  

  DISABLE_SIZE=yes  

  netstat -n | awk '/^tcp/ {++state[$NF]} END {for(key in state) print key,"\t",state[key]}'  

  netstat -nat|grep -i "80"|wc -l  

  服务器上的一些统计数据：  

  1)统计80端口连接数  

  netstat -nat|grep -i "80"|wc -l  

  1  

  2）统计httpd协议连接数  

  ps -ef|grep nginx|wc -l  

  ps -ef|grep php-fcgi|wc -l  

  1  

  3）、统计已连接上的，状态为“established'  

  netstat -na|grep ESTABLISHED|wc -l  

  2  

  4)、查出哪个IP地址连接最多,将其封了.  

  netstat -na|grep ESTABLISHED|awk '{print $5}'|awk -F: '{print $1}'|sort|uniq -c|sort -r +0n  

  netstat -na|grep FIN_WAIT_1|awk '{print $5}'|awk -F: '{print $1}'|sort|uniq -c|sort -r +0n  

  netstat -na|awk '{print $5}'| sort | uniq -c | sort -r | awk -F' ' '{if ($1 > 50) print $2}'  

  netstat快速查看一下TCP连接情况  

  netstat -n | awk '/^tcp/ {++S[$NF]} END {for(a in S) print a, S[a]}'  

  通过man netstat可以了解SYN_RCVD的意义。SYN_RCVD表示当前未完成的TCP SYN队列  

  用命令：  

  　　# netstat -an | grep SYN | wc -l  

  $netstat -an | grep SYN_RECV | wc  

  97     582    7857  

  $netstat -an | grep 80 | wc  

  916    5500   74164
