一、監控服務端口腳本

腳本是基于telnet命令進行監控端口服務，所以運行腳本前務必檢查telnet工具是否安裝！

[root@shell jao]# cat monitor_prot.sh #!/bin/bash prot_status(){ temp_file=`mktemp prot_status.XXX`# 1、判斷telnet命令是否存在 [ ! -x /usr/bin/telnet ] && echo "telnet: not found comand" && exit 1# 2、測試端口 $1:IP地址 $2:端口號 ( telnet $1 $2 <<EOF quit EOF) &> $temp_file# 3、分析文件中內容 判斷結果if egrep "\^]" $temp_file &>/dev/null;thenecho "$1 $2 open" elseecho "$1 $2 down" firm -f $temp_file } prot_status $1 $2

運行腳本

# 語法： IP地址 端口號 [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、編譯安裝Nginx腳本

[root@shell jao]# cat nginx.sh #!/bin/bashclear 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=${NGINX_GROUP} --with-http_ssl_module --with-http_stub_status_module"##function nginx_check(){ # 1、監測當前用戶 要求為root if [ "$USER" != 'root' ];thenecho "need to be root so that"exit 5 fi# 2、檢查wget命令 WGET_CHECK=$(rpm -q wget) if [ $? -ne 0 ];then yum -y install wget &> /dev/null fi }nginx_install_pre(){ # 1、安裝依賴 if !

運行腳本

[root@shell jao]# bash nginx.sh

腳本運行成功效果圖：
可改變量：

6 NGINX_VERSION="nginx-1.16.0" #定義安裝nginx版本7 NGINX_INSTALL_DOC="/usr/local/nginx" #定義安裝目錄8 NGINX_USER="nginx" #定義nginx用戶9 NGINX_GROUP="nginx" #定義nginx組10 NGINX_CONFIGURE="...省略" #定義nginx編譯需要模塊及參數！# 注意：在定義 NGINX_CONFIGURE變量模塊時 需要安裝此模塊需要的依賴(如:with-http_ssl_module模塊就需要依賴openssl 否則就會報錯！)

三、監控一個主機狀態腳本

[root@shell jao]# cat monitor_host.sh #!/bin/bashfor ((i=1;i<4;i++));doif ping -c1 $1 &>/dev/null;thenexport ping_count"$i"=1elseexport ping_count"$i"=0fi# 時間間隔sleep 0.5 done# 3次ping 失敗報警 if [ $ping_count1 -eq $ping_count2 ] && [ $ping_count2 -eq $ping_count3 ] && [ $ping_count1 -eq 0 ]thenecho "$1 is down"elseecho "$1 is up" fi# 取消上面定義的變量 unset ping_count1 unset ping_count2 unset ping_count3

運行腳本

語法： bash monitor_host.sh 監控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、統計內存、CPU使用前十進程腳本

[root@shell jao]# cat top10.sh #!/bin/bashmemory(){ #1、收集任務管理器進程信息 temp_file=$(mktemp memory.XXX) top -b -n1 > $temp_file # -b 顯示所有top內容 # -n1 動態顯示1次后退出#2、按進程統計內存使用大小 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 $temp_file # -n +8 從第八行開始輸出內容 # sort -k 表示從第幾列排序 -r 倒序 -n 以數字類型排序 }cpu(){ #1、收集任務管理器進程信息 temp_file=$(mktemp cpu.XXX) top -b -n1 > $temp_file#2、按進程統計內存使用大小 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----------' memoryecho '----------cpu----------' cpu

執行腳本

[root@shell jao]# bash top10.sh ----------memory---------- 28684 firewalld 16572 tuned 14496 sshd 12888 polkitd 11316 NetworkManager 9380 bash 7084 ssh 6244 systemd 6120 vmtoolsd 6072 VGAuthService ----------cpu---------- 0 xfs-reclaim/sda 0 xfs-reclaim/dm- 0 xfs_mru_cache 0 xfs-log/sda1 0 xfs-log/dm-0 0 xfs-eofblocks/s 0 xfs-eofblocks/d 0 xfs-data/sda1 0 xfs-data/dm-0 0 xfs-conv/sda1

五、I/O列長度監控腳本

[root@shell jao]# cat io.sh #!/bin/bash# 判斷系統是否安裝iostat scipt 基于iostat命令 [ ! -x /usr/bin/iostat ] && echo "iostat:command not found"&& exit 1 io(){#匹配以sd開頭的磁盤 如磁盤是vd，或其他開頭 這里直接改 Device_name變量即可。 Device_name=sd Device_length=`iostat -d -x | egrep "^$Device_name[[:alpha:]]|^dm" |wc -l`# tail -n +K 表示從第K個開始輸出 iostat -x 1 3 | egrep "^sd[[:alpha:]]|^dm" |tail -n +$((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++));doio done

運行腳本

[root@shell jao]# bash io.sh 0 dm-0 0 dm-1 0 sda ----- 0 dm-0 0 dm-1 0 sda ----- 0 dm-0 0 dm-1 0 sda ----- 0 dm-0 0 dm-1 0 sda ----- 0 dm-0 0 dm-1 0 sda -----

六、計算內存使用率占比

[root@shell jao]# cat memoryinfo.sh #!/bin/bash# free參數詳解: total(總量),free(未使用),buff/cache(緩存),shared(共享內存),swap(交換分區) # buff和cache區別？ # buff 做塊設備的緩沖大小 # cache 用來做文件的緩沖 MEM_TOTAL=`free -h |awk 'NR==2{print $2}'`MEM_USE=`free -h |awk 'NR==2{print $3}'` MEM_USED=`free | grep -i mem |awk '{print $3/$2*100"%"}'`MEM_FREE=`free -h |awk 'NR==2{print $4}'` MEM_FREED=`free | grep -i mem |awk '{print $4/$2*100"%"}'`MEM_BUFF_CACHE=`free -h |awk 'NR==2{print $6}'` MEM_BUFF_CACHED=`free | grep -i mem |awk '{print $6/$2*100 "%"}'`MEM_SHARE=`free -h |awk 'NR==2{print $5}'` MEM_SHARED=`free | grep -i mem |awk '{print $5/$2*100 "%"}'` MEM_ZONE=`head -3 /proc/meminfo | awk 'NR==1{t=$2}NR==2{f=$2;print(t-f)*100/t"%"}'`echo -e "\t\e[1;32m內存總量: $MEM_TOTAL \e[0m" echo -e "\t\e[1;32m內存總量減剩余內存(所有已使用)占比: $MEM_ZONE \e[0m" echo -e "\t\e[1;32m已使用: $MEM_USE 占比: $MEM_USED \e[0m" echo -e "\t\e[1;32m剩 余: $MEM_FREE 占比: $MEM_FREED \e[0m" echo -e "\t\e[1;32m共 享: $MEM_SHARE 占比: $MEM_SHARED \e[0m" echo -e "\t\e[1;32m緩沖區: $MEM_BUFF_CACHE 占比: $MEM_BUFF_CACHED \e[0m"

[root@shell jao]# bash memoryinfo.sh 內存總量: 976M 內存總量減剩余內存(所有已使用)占比: 69.5806% 已使用: 130M 占比: 13.3869% 剩 余: 296M 占比: 30.4062% 共 享: 6.7M 占比: 0.691013% 緩沖區: 548M 占比: 56.2177%

七、一鍵部署wordpress博客平臺

[root@shell jao]# cat wordpress.sh #!/bin/bash clear ## variabled WORDPRESS_VERSION='5.5.6' DB_ROOT_PWD='123.com' DB_USER='lisi' DB_USER_PWD='123.com' DB_NAME='blog'## function echo "Please wait a few minutes..." word_yum(){ (firewall-cmd --add-port=80/tcp --permanent) &>/dev/null (firewall-cmd --add-service=mysql --permanent;firewall-cmd --add-port=9000/tcp --permanent) &>/dev/null firewall-cmd --reload &>/dev/null (sed -i s/SELINUX=enforcing/SELINUX=disabled/g /etc/selinux/config;setenforce 0) &>/dev/null TIME_CURRENT=$(date +%X | awk '{print $1}') mkdir /etc/yum.repos.d/${TIME_CURRENT}.bak mv /etc/yum.repos.d/* /etc/yum.repos.d/${TIME_CURRENT}.bak &>/dev/null[ ! -x /usr/bin/wget ] && echo "wget: command not found" && exit 5if !
