脚本是基于telnet命令进行监控端口服务，所以运行脚本前务必检查telnet工具是否安装！
[root@shell jao]# cat monitor_prot.sh
#!/bin/bash
prot_status(){
temp_file=`mktemp prot_status.XXX`
# 1、判断telnet命令是否存在
[ ! -x /usr/bin/telnet ] && echo "telnet: not found comand" && exit 1
# 2、测试端口 $1:IP地址 $2:端口号
( telnet $1 $2 < $temp_file
# 3、分析文件中内容 判断结果
if egrep "^]" $temp_file &>/dev/null;then
echo "$1 $2 open"
else
echo "$1 $2 down"
fi
rm -f $temp_file
}
prot_status $1 $2
运行脚本
# 语法： IP地址 端口号 [root@shell jao]# bash monitor_prot.sh 192.168.1.68 22 192.168.1.68 22 open [root@shell jao]# bash monitor_prot.sh 192.168.1.68 80 192.168.1.68 80 open [root@shell jao]# bashmonitor_prot.sh 192.168.1.68 21 192.168.1.68 21 down二、编译安装Nginx脚本
[root@shell jao]# cat nginx.sh
#!/bin/bash
clear
echo "Preparations before installation..."
##variabled
NGINX_VERSION="nginx-1.16.0"
NGINX_INSTALL_DOC="/usr/local/nginx"
NGINX_USER="nginx"
NGINX_GROUP="nginx"
NGINX_CONFIGURE="--prefix=${NGINX_INSTALL_DOC} --user=${NGINX_USER} --group=${NGINX_GROUP} --with-http_ssl_module --with-http_stub_status_module"
##function
nginx_check(){
# 1、监测当前用户 要求为root
if [ "$USER" != 'root' ];then
echo "need to be root so that"
exit 5
fi
# 2、检查wget命令
WGET_CHECK=$(rpm -q wget)
if [ $? -ne 0 ];then
yum -y install wget &> /dev/null
fi
}
nginx_install_pre(){
# 1、安装依赖
if ! (yum -y install make zlib zlib-devel gcc-c++ libtool openssl openssl-devel pcre-devel openssl openssl-devel elinks 1>/dev/null);then
echo "ERROR:YUM install error"
exit 5
fi
# 2、下载nginx源码包
if (wget http://nginx.org/download/${NGINX_VERSION}.tar.gz &>/dev/null);then
tar zxf ${NGINX_VERSION}.tar.gz
if [ ! -d ${NGINX_VERSION} ];then
echo "ERROR:not found ${NGINX_VERSION}";exit 5
fi
else
echo "ERROR:wget download file ${NGINX_VERSION}.tar.gz fail"
fi
}
nginx_install_make(){
(groupadd ${NGINX_GROUP} ;useradd -s /sbin/nologin -r -M -g ${NGINX_GROUP} ${NGINX_USER}) &>/dev/null
cd ${NGINX_VERSION}
echo "nginx configure..."
if ./configure ${NGINX_CONFIGURE} 1>/dev/null;then
echo "nginx make ..."
if make 1>/dev/null;then
echo "nginx make install ..."
if make install 1>/dev/null;then
echo "nginx install success"
else
echo "ERROR: nginx install tail!";exit 5
fi
else
echo "ERROR: nginx make tail!";exit 5
fi
else
echo"ERROR: nginx configure tail!";exit 5
fi
}
# 配置nginx开机自启,使用systemctl 管理nginx服务
nginx_enable(){
cat > /usr/lib/systemd/system/nginx.service </dev/null
}
nginx_start(){
TEMP_NGINX=$(mktemp nginx.XXX)
if systemctl start nginx.service;then
echo "nginx start SUCCESS!"
clear
elinks http://localhost -dump >${TEMP_NGINX}
head -n +11 ${TEMP_NGINX}
rm -f ${TEMP_NGINX}
echo -e "e[1;36m Manager Nginx:e[0m e[0;32m systemctl start|stop|status|restart| nginx.service e[0m"
else
echo "nginx stop FAIL"
fi
}

运行脚本
[root@shell jao]# bash nginx.sh
脚本运行成功效果图：
可改变量：
6 NGINX_VERSION="nginx-1.16.0" #定义安装nginx版本 7 NGINX_INSTALL_DOC="/usr/local/nginx" #定义安装目录 8 NGINX_USER="nginx" #定义nginx用户 9 NGINX_GROUP="nginx" #定义nginx组 10 NGINX_CONFIGURE="...省略" #定义nginx编译需要模块及参数！ # 注意：在定义 NGINX_CONFIGURE变量模块时 需要安装此模块需要的依赖(如:with-http_ssl_module模块就需要依赖openssl 否则就会报错！)三、监控一个主机状态脚本
[root@shell jao]# cat monitor_host.sh
#!/bin/bash
for ((i=1;i<4;i++));do
if ping -c1 $1 &>/dev/null;then
export ping_count"$i"=1
else
export ping_count"$i"=0
fi
# 时间间隔
sleep 0.5
done
# 3次ping 失败报警
if [ $ping_count1 -eq $ping_count2 ] && [ $ping_count2 -eq $ping_count3 ] && [ $ping_count1 -eq 0 ]
then
echo "$1 is down"
else
echo "$1 is up"
fi
# 取消上面定义的变量
unset ping_count1
unset ping_count2
unset ping_count3
运行脚本
语法： bash monitor_host.sh 监控IP地址 [root@shell jao]# bash monitor_host.sh 192.168.1.68 192.168.1.68 is up [root@shell jao]# bash monitor_host.sh 192.168.1.69 192.168.1.69 is down四、统计内存、CPU使用前十进程脚本
[root@shell jao]# cat top10.sh
#!/bin/bash
memory(){
#1、收集任务管理器进程信息
temp_file=$(mktemp memory.XXX)
top -b -n1 > $temp_file
# -b 显示所有top内容
# -n1 动态显示1次后退出
#2、按进程统计内存使用大小
tail -n +8 $temp_file | awk '{array[$NF]+=$6}END{for (i in array) print array[i],i}'| sort -k 1 -n -r | head -10
rm -f $temp_file
# -n +8 从第八行开始输出内容
# sort -k 表示从第几列排序 -r 倒序 -n 以数字类型排序
}
cpu(){
#1、收集任务管理器进程信息
temp_file=$(mktemp cpu.XXX)
top -b -n1 > $temp_file
#2、按进程统计内存使用大小
tail -n +8 $temp_file | awk '{array[$NF]+=$9}END{for (i in array) print array[i],i}'| sort -k 1 -n -r | head -10
rm -f $temp_file
}
echo '----------memory----------'
memory
echo '----------cpu----------'
cpu

[root@shell jao]# cat io.sh
#!/bin/bash
# 判断系统是否安装iostat scipt 基于iostat命令
[ ! -x /usr/bin/iostat ] && echo "iostat:command not found"&& exit 1
io(){
#匹配以sd开头的磁盘 如磁盘是vd，或其他开头 这里直接改 Device_name变量即可。
Device_name=sd
Device_length=`iostat -d -x | egrep "^$Device_name[[:alpha:]]|^dm" |wc -l`
# tail -n +K 表示从第K个开始输出
iostat -x 1 3 | egrep "^sd[[:alpha:]]|^dm" |tail -n +$((Device_length+1)) | awk '{io_long[$1]+=$9}END{for (i in io_long)print io_long[i],i}'
echo "-----"
}
for ((i=1;i<6;i++));do
io
done
运行脚本

[root@shell jao]# cat memoryinfo.sh
#!/bin/bash
# free参数详解: total(总量),free(未使用),buff/cache(缓存),shared(共享内存),swap(交换分区)
# buff和cache区别？
# buff 做块设备的缓冲大小
# cache 用来做文件的缓冲
MEM_TOTAL=`free -h |awk 'NR==2{print $2}'`

执行脚本
