快速搭建内网测试网络,简单模拟WEB集群

svn项目

模拟WEB集群

后端WEB集群192.168.1.231:8080和192.168.1.232:8080.WEB后端可以按照需要增加,不同目录启动不同端口,通过使用192.168.1.231:80作为负载均衡访问.

upstream  www.front.com
{
    server   192.168.1.232:8080;
    server   192.168.1.231:8080;
}

server
{
    listen  80;
    server_name  192.168.1.231;

    location / {
        proxy_pass        http://www.front.com;
        proxy_set_header   Host             $host;
        proxy_set_header   X-Real-IP        $remote_addr;
        proxy_set_header   X-Forwarded-For  $proxy_add_x_forwarded_for;
    }
}

SVN自动发布

使用SVN提交时，注释中输入"auto_deploy",自动发布到231，232的项目测试服务器.svn钩子文件post-commit

#!/bin/bash

REPOS="$1"
REV="$2"
if ( svnlook log -r $REV /data/www/svn/gtl/ |grep "auto_deploy" )
then

    echo "`date` auto_deploy">> /tmp/testsvn.log
#front1
    ssh root@192.168.1.231 'svn revert -R /data/wwwroot/gtl --username "sylar" --password "gtl1023"'
    ssh root@192.168.1.231 'svn update /data/wwwroot/gtl/ --username "sylar" --password "gtl1023"'
    ssh root@192.168.1.231 'chown www.www -R /data/wwwroot/gtl'

#front2
    ssh root@192.168.1.232 'svn revert -R /data/wwwroot/gtl --username "sylar" --password "gtl1023"'
    ssh root@192.168.1.232 'svn update /data/wwwroot/gtl/ --username "sylar" --password "gtl1023"'
    ssh root@192.168.1.232 'chown www.www -R /data/wwwroot/gtl'

#admin
    ssh root@192.168.1.232 'svn revert -R /data/wwwroot/admin/ --username "sylar" --password "gtl1023"'
    ssh root@192.168.1.232 'svn update /data/wwwroot/admin/ --username "sylar" --password "gtl1023"'
    ssh root@192.168.1.232 'chown www.www -R /data/wwwroot/admin'


#API
    ssh root@192.168.1.235 'svn revert -R /data/wwwroot/api/ --username "sylar" --password "gtl1023"'
    ssh root@192.168.1.235 'svn update /data/wwwroot/api/ --username "sylar" --password "gtl1023"'
    ssh root@192.168.1.235 'chown www.www -R /data/wwwroot/api'
fi

另外一个SVN钩子，强制SVN提交时输入注释

#!/bin/sh
REPOS="$1"
TXN="$2"
SVNLOOK=/usr/bin/svnlook
LOGMSG=$($SVNLOOK log -t "$TXN" "$REPOS" | grep "[a-zA-Z0-9]" | wc -c)
if [ "$LOGMSG" -lt 10 ]; then
echo -e "\n 提交文件时必须添加注释，提交中止."1>&2
exit 1
fi

git项目

GIT钩子post-receive

代码服务器的git用户需要对目标机器做ssh密钥授权,并且保证能够以目标机器的sudo用户登录

#!/bin/sh

IS_BARE=$(git rev-parse --is-bare-repository)
if [ -z "$IS_BARE" ]; then
echo >&2 "fatal: post-receive: IS_NOT_BARE"
exit 1
fi

unset GIT_DIR

echo "==============================================="

ssh gtl@xxx.xxx.xxx.xxx '/bin/bash /home/project/local.sh'
ssh gtl@xxx.xxx.xxx.xxx '/bin/bash /home/project/local.sh'
ssh gtl@xxx.xxx.xxx.xxx '/bin/bash /home/project/local.sh'

echo "====================done======================="

目标机local.sh

目标机器需要首先克隆仓库到本地/data/source_code/. /data/backup/settings.py为项目的配置文件,先备份再cp,然后重启项目.目标机器的git需要cp,chown权限

#!/bin/bash
cd /data/source_code/
sudo git pull
sudo cp /data/wwwroot/project/bcdemo/settings.py /data/backup/settings.py -f
sudo cp /data/source_code/* /data/wwwroot/project/ -a
sudo cp /data/backup/settings.py /data/wwwroot/project/bcdemo/settings.py -f
sudo chown www.www /data/wwwroot/project/ -R
sudo systemctl stop demo
sudo systemctl restart demo
sudo echo "update done,`date -d today +"%Y-%m-%d %T"`" >> /home/project/test.txt
