Linux开发，只要在Linux环境下的一切相关开发，包括c++\goLang\Web,shell命令等。

按文件创建日期进行同步 

#!/bin/bash

time_now=`ssh -l root 172.17.101.163 "date +%s"`
rooms=`ssh -l root 172.17.101.163 "ls /home/waypal/volume/kms/kms-media"`
for room in $rooms

   echo "you choise:$answer"
   if [ $answer != y ];then
      exit;
   fi

查看docker的IP地址 

容器内部
cat /etc/hosts
---------------------------------
宿主机
1.docker ps
CONTAINER ID        IMAGE                                COMMAND                  CREATED             STATUS              PORTS

2.docker inspect -f '{{range .NetworkSettings.Networks}}{{.IPAddress}}{{end}}' 2a0fddf3b486

添加EPEL源

[root@localhost ~]# wget http://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm

[root@localhost ~]# rpm -ivh epel-release-latest-7.noarch.rpm

[root@localhost ~]# yum repolist ##检查是否已添加至源列表

OK，检查好已添加至源后就可以进行yum安装了

VMWare端口映射

在进行kms的例子测试时，发现快速试验kurento的最佳方式就是【kurento-tutorial-java】+【kurento/kurento-media-server】，然而笔记本摄像头在linux中不被支持，故通过VMware把linux中的kms端口映射到主机中。

ssh的反向代理，连接回家庭电脑。

#公网IP
host_proxy=39.108.x.y
#公网相应主机登录名
host_proxy_user_name=abc
#使用密码方式登录，非免密码方式。需要yum install sshpass软件。
#公网主机的用户密码，免密码方式时为空。
host_proxy_user_pwd=
#需要被登录的家庭主机登录名。
local_user_name=abc

自定义菜单和修改桌面图标大小

LINUX CENTOS 7 X86_64中开始菜单的编辑安装软件alacarte即可
命令：$ yum install alacarte
安装好后在Application->sundry中就能看到“Main Menu”的选项了。
点击“Main Menu”就可以很方便的对菜单进行编辑。
修改桌面图标大小

源码备份脚本 

\#!/bin/bash

set -x
path_current=`pwd`
path_script=$(cd "$(dirname "$0")"; pwd)
echo "path_script="$path_script
path_waypal=$path_script/waypal.from.101.200.132/waypal
if [ -d $path_waypal ];then
   echo "find the directory:$path_waypal"
else
   mkdir -p $path_waypal
fi

path_targz=$path_script/waypal.from.101.200.162/waypal_backup_`date +%Y-%m-%d`.tar.gz
path_targztmp=$path_targz'.tmp'
rsync --exclude  ".git" -ave ssh ljb@101.200.132:/home/ljb/waypal  $path_waypal && tar -cvzf $path_targztmp $path_waypal && mv $path_targztmp $path_targz && rm $path_script/waypal.from.101.200.132/waypal_backup_`date -d '-5 days' +%Y-%m-%d`.tar.gz

获取当前目录脚本 

#!/usr/bin/bash
path_current=$(cd "$(dirname "$0")"; pwd)
name_current=$(basename "$0" .sh)
echo $path_current
echo $name_current
rm -vf $path_current/backup/"$name_current"_`date -d '-10 days' +%Y-%m-%d`*.sql.gz
mysqldump -h waypaldb.mysql.rds.aliyuncs.com  -u waypal -p'1234567' --databases waypaldev | gzip > $path_current/backup/"$name_current"_`date +%Y-%m-%d-%H-%M`.sql.gz
