3、监控主机的磁盘空间，当使用空间超过90%就通过发mail来发警告
/bin/bash#monitoravailablediskspaceSPACE='
df|sed-n'
/\/\$/p'
|gawk'
{print\$5}'
|sed'
s/%//'
if[\$SPACE-ge90]thenfty89@fi
4、监控CPU和内存的使用情况
/bin/bash#scripttocapturesystemstatisticsOUTFILE=/home/xu/capstats.csv
DATE='
date+%m/%d/%Y'
TIME='
date+%k:
%m:
%s'
TIMEOUT='
uptime'
VMOUT='

USERS='
echo\$TIMEOUT|gawk'
{print\$4}'
'
LOAD='
{print\$9}'
|sed"
s/,//'
FREE='
echo\$VMOUT|sed-n'
/[0-9]/p'
|sed-n'
2p'
{print\$4}'
IDLE='
|gawk'
{print\$15}'
echo"
\$DATE,\$TIME,\$USERS,\$LOAD,\$FREE,\$IDLE"
》\$OUTFILE
5、全方位监控主机
/bin/bash#check_xu.sh#0****/home/check_xu.shDAT="
`date+%Y%m%d`"
HOUR="
`date+%H`"
DIR="
/home/oslog/host_\${DAT}/\${HOUR}"
DELAY=60COUNT=60#whethertheresponsibledirectoryexistif!

\${DIR}/top_\${DAT}.log2>
&
1&
#cpucheck/usr/bin/sar-u\${DELAY}\${COUNT}>
\${DIR}/cpu_\${DAT}.log2>
#/usr/bin/mpstat-P0\${DELAY}\${COUNT}>
\${DIR}/cpu_0_\${DAT}.log2>
#/usr/bin/mpstat-P1\${DELAY}\${COUNT}>
\${DIR}/cpu_1_\${DAT}.log2>
#memorycheck/usr/bin/vmstat\${DELAY}\${COUNT}>
\${DIR}/vmstat_\${DAT}.log2>
#I/Ocheck/usr/bin/iostat\${DELAY}\${COUNT}>
\${DIR}/iostat_\${DAT}.log2>
#networkcheck/usr/bin/sar-nDEV\${DELAY}\${COUNT}>
\${DIR}/net_\${DAT}.log2>
#/usr/bin/sar-nEDEV\${DELAY}\${COUNT}>
\${DIR}/net_edev_\${DAT}.log2>
放在crontab里每小时自动执行：
0****/home/check_xu.sh
这样会在/home/oslog/host_yyyymmdd/hh目录下生成各小时cpu、内存、网络，IO的统计数据。
如果某个时间段产生问题了，就可以去看对应的日志信息，看看当时的主机性能如何。
生产服务器LNMP全自动安装脚本
使用方法：
将nginx_php代码保存一个文件，例如nginx_php。
上传到服务器上执行。
此脚本在CentOS5.6i386/x86_64环境下通过。
bashnginx_php出现提示，如下列图所示。
根据大家自己的需要选择数字中任意一个，开始全自动安装LNMP的世界中去吧。
如果之前安装过nginx或者php的话，脚本会自动检测它们是不是安装过。
例如
就会提示nginx或者php已经安装过了。
