[工具] Shell 批量将本地文件拷贝到多个远程服务器

介绍

基本信息

作者：朱明宇
名称：批量将本地文件拷贝到多个远程服务器
作用：批量将本地文件拷贝到多个远程服务器

使用方法

1. 在此脚本的分割线内写入相应的内容
2. 给此脚本添加执行权限
3. 执行此脚本

脚本分割线里的变量

1. myuser=”eternalcenter” #登录远程服务器的用户
2. myserver=”192.168.1.1 192.168.1.2″ #要登录的远程服务器，以空格隔开
3. myfile=”/home/zhumingyu/test1.txt /home/zhumingyu/test2.txt” #要拷贝的文件，以空格隔开，必须是绝对路劲
4. mysudo=”no” #是否使用 sudo 提权，请选择 yes 或者 no

注意

1. 此脚本执行前必须要先保证执行本脚本的用户能无密码 ssh 远程这些远程服务器
2. 必须以 root 用户执行本脚本

脚本

#!/bin/bash

####################### Separator ########################

myuser="eternalcenter"
myserver="192.168.1.1 192.168.1.2" #each server is separated by a space
myfile="/home/zhumingyu/test1.txt /home/zhumingyu/test2.txt" #each file is separated by a space, absolute road force must be used
mysudo="no" #please choose "yes" or "no"

####################### Separator ########################

mynow=`date +%Y-%m-%d-%H-%s`
mycontext=${myfile##*\/}

if [ $mysudo == 'yes' ];then
        myreplace(){
                scp $3 $1@$2:/tmp/$5
                ssh -t $1@$2 "sudo -u root su - root -c \"mv $3 $3-$4;mv /tmp/$5 $3\""
        }
        echo "use sudo"
fi

if [ $mysudo == 'no' ];then
        myreplace(){
                scp $3 $1@$2:/tmp/$5
                ssh -t $1@$2 "mv $3 $3-$4;mv /tmp/$5 $3"
        }
        echo "don't use sudo"
fi

for files in $myfile
do

        if [ -f $files ];then

                for servers in `echo $myserver`
                do
                                myreplace $myuser $servers $files $mynow $mycontext
                done
        else
                echo "$files does not exist"

[工具] Shell 显示所有可升级的软件版本，并自动生成相应的升级命令 （openSUSE & SLES）

介绍

基本信息

作者：朱明宇
名称：openSUSE & SLES 显示所有可升级的软件版本，并自动生成相应的升级命令
作用：openSUSE & SLES 显示所有可升级的软件版本，并自动生成相应的升级命令

使用方法

给此脚本添加执行权限
执行此脚本
执行此脚本大致会生成以下内容：

zypper update  MozillaFirefox-78.12.0-lp152.2.61.1 MozillaFirefox-translations-common-78.12.0-lp152.2.61.1 alsa-oss-1.1.8-lp152.4.3.1

脚本

#!/bin/bash

m=''

for n in `zypper list-updates | tail -n +5 | awk '{print $7"-"$11}'`
do
        m="$m $n"
done

echo "zypper update $m"

[工具] Shell 自动化部署 LNMP + SSL 平台 （openSUSE Leap 15 版）

介绍

基本信息

作者：朱明宇
名称：自动化部署 LNMP + SSL 平台
作用：自动化安装 LNMP + SSL，即通过 Linux、Nginx、MariaDB、PHP、php-fpm、SSL，实现 HTTPS

使用方法

1. 将网站的网页数据备份、网站的 SSL 公钥、网站的 SSL 私钥、网站的数据库备份和本脚本，5 个文件放在同一目录下
2. 如果没有网站的数据库备份则将网页数据备份、网站的 SSL 公钥、网站的 SSL 私钥和本脚本，4 个文件放在同一目录下
3. 在此脚本的分割线内写入相应的内容
4. 开启系统的 selinux
5. 给此脚本添加执行权限
6. 执行此脚本：./<执行本脚本>

脚本分割线里的变量

1. webdomain=”eternalcenter.com” #网站的域名，注意不要在前面加任何前缀
2. webtar=”eternalcenter-backup-*.tar.gz” #网站的网页数据备份，如果没有这个备份，可以下载一个开源的 WordPress 网页程序
3. webcrt=”eternalcenter.com.crt” #网站 SSL 的公钥，可以自己创建也可以在 FreeSSl 上申请
4. webkey=”eternalcenter.com.key” #网站 SSL 的私钥，可以自己创建也可以在 FreeSSL 上申请
5. sqlbackup=”eternalcenter-backup-*.sql” #网站数据库数据备份，如果没有这个备份（数据库是全量备份），则这里可以为空
6. db=”ec” #网站在数据库中库
7. dbuser=”ec” #网站在数据库中的用户
8. dbuserpw=”eternalcenter” #网站在数据库中的用户密码
9. dbrootpw=”eternalcenter” #数据库的 root 密码

注意

1. 服务器的系统需要是 openSUSE 15 版本
2. 服务器系统要配置好可用的软件源（最好是软件数量最多的官方版本）
3. 服务器要能够连接外网

脚本

#!/bin/bash

[工具] Shell 检测服务器某个端口有没有启动

介绍

基本信息

作者：朱明宇
名称：检测服务器某个端口有没有启动
作用：检测服务器某个端口有没有启动

使用方法

1. 在此脚本的分割线内写入相应的内容
2. 给此脚本添加执行权限
3. 执行此脚本
4. 如果被检测的端口被启动则会被记录在指定文件里

脚本分割线里的变量

1. checkport=’7111′ #被检测的端口
2. logfile=’checkportlog.txt’ #记录文件

脚本

#!/bin/bash

####################### Separator ########################
checkport='7111'
logfile='checkportlog.txt'
####################### Separator ########################

a=`/sbin/ss -ntulap | grep udp | grep $checkport | awk '{print $7}' | awk -F'"' '{print $2}'`

if [ -n "$a" ];then
       echo `date` >> $logfile
       echo $checkport >> $logfile
       echo `/sbin/ss -ntulap | grep udp | grep $checkport | awk '{print $7}' | awk -F'"' '{print $2}'` >> $logfile
