规划中平台是具备一定的通用性和可扩展性，所以在写脚本时引入了参数，以便实现代码的复用
**1、Linux 基础信息巡检**点击查看代码
sys_check(){
echo "主机名称：`hostname`"
#echo "操作系统：`cat /etc/*-release|awk 'END{print}'`"
echo "操作系统：`cat /etc/*-release|awk 'END{print}'|cut -d = -f 2|sed 's/"//g'`"

cpu_Check(){
Check_Res=`sar -u 1 5 |grep Average`
echo "CPU用户占比：`echo $Check_Res|awk '{printf $3}'`%"

disk_Check(){
echo "`df -h | sort |grep -E "/sd|/mapper" |awk '{print "ResCheck_DiskRa te：分区" $1 ," 合 计"$2" 已用" $3 " 剩余"$4 " 使用占比 " $5}'`"

ip_Addr(){
echo "`ifconfig -a|grep inet|grep -v 127.0.0.1|grep -v inet6 |awk -F " " 'BEGIN {count=0} {count=count+1; print "IP地址" count "：" $2}'`"
}
sys_check

mem_check
disk_Check
ip_Addr
执行效果如图：
**2、服务器端口检查** 点击查看代码
port_Check(){
# local service_port=50456
service_port=$1
Temp_S=`netstat -naut| grep -v tcp6 |grep "0.0.0.0:$service_port "`
if [ -z "$Temp_S" ]; then
echo "ResCheck_Port：$service_port Unknown"
fi
if [ -n "$Temp_S" ]; then
#echo `echo $Temp_S|awk '{ print "ResCheck_Port：" service_port " " $6}' service_port=$service_port `
echo "ResCheck_Port：$service_port LISTEN"
fi
}
port_Check $1
效果图：
**3、检查远程主机端口状态**点击查看代码
[root@hfeboasmg01 script]# cat remotePort_check.sh
remotePort_Check(){
# local service_port=50456
Host=$1
Port=$2
#Temp_S=`netstat -naut| grep -v tcp6 |grep "0.0.0.0:$service_port "`
#nc -z -v -w 5 $Host $Port &> /dev/null
nc -z -v -w 5 $Host $Port
res=$?
#Do whatever you want
if [ $res -eq 0 ]; then
echo ResCheck_remotePort： port $Port on $Host is open
else
echo ResCheck_Port：port $Port on $Host is closed
fi
}
remotePort_Check $1 $2
**4、服务状态检查**点击查看代码
service_Check(){
#返回服务状态
service_name=$1
#local service_name="sshd"
echo `systemctl status $service_name |grep Active |awk '{print "ResCheck_Service：" service_name " " $2}' service_name=$service_name`
}
service_Check $1
~
**5、网站可用性检查** 点击查看代码
url_Check(){
#通过端口的返回值判断状态
url_path=$1
#local url_path="https://asts.cxmt.com:8080"
#echo `curl -k -s --head $url_path |awk 'NR==1 {print "ResCheck_URL：" url_path " "$2$3}' url_path=$url_path`
url_checkRes=`curl --connect-timeout 3 -k -s --head $url_path`
if [ "$url_checkRes" ]; then
echo `curl -k -s --head $url_path |awk 'NR==1 {print "ResCheck_URL：" url_path " "$2$3}' url_path=$url_path`
else
echo "ResCheck_URL：$url_path Unreachable "
fi
}
url_Check $1
至此，linux 平台的几个巡检脚本基本完成了
