jenkins 通过nginx 热部署 应用

1.Git-分支 参数化

2.编译环境 参数化

3.大版本 参数化

git地址配置，并使用 分支参数

创建SSH-Server步骤

第一个应用：

分2步处理，也可直接 脚本
1.创建目录 按日期建 BUILD_YM是 build-timestamper 全局变量
if [ ! -d "~/srv/webapp/PublishHistory/${BUILD_YM}" ]; then
    mkdir -p ~/srv/webapp/PublishHistory/${BUILD_YM}
fi
if [ ! -d "/srv/webapp/PublishHistory/${BUILD_YM}/${VersionMajor}.${BUILD_VERSION}" ]; then
    mkdir -p /srv/webapp/PublishHistory/${BUILD_YM}/${VersionMajor}.${BUILD_VERSION}
fi
if [ ! -d "/srv/webapp/backup" ]; then
    mkdir -p /srv/webapp/backup
fi
if [ ! -d "/srv/webapp/api/publish" ]; then
    mkdir -p /srv/webapp/api/publish
fi

2.ssh 传输文件完毕后 备份旧代码、更新代码（一定要是 服务否则 ssh停止后所有相关进程都会被停止）
mv ~/srv/webapp/PublishHistory/${BUILD_YM}/webapp.WebApi.zip /srv/webapp/PublishHistory/${BUILD_YM}/webapp.WebApi.${VersionMajor}.${BUILD_VERSION}.zip

zip -qr /srv/webapp/backup/webappaip.${VersionMajor}.${BUILD_VERSION}.${BUILD_YM}.bak.zip  /srv/webapp/api/publish -x "/srv/webapp/api/publish/Logs/*"


unzip /srv/webapp/PublishHistory/${BUILD_YM}/webapp.WebApi.${VersionMajor}.${BUILD_VERSION}.zip -d /srv/webapp/PublishHistory/${BUILD_YM}/${VersionMajor}.${BUILD_VERSION}

systemctl stop webapp.api

rm -rf /srv/webapp/api/publish/wwwroot

mv -bf /srv/webapp/PublishHistory/${BUILD_YM}/${VersionMajor}.${BUILD_VERSION}/*  /srv/webapp/api/publish
chmod u+rwx /srv/webapp/api/publish/webapp.WebApi

rmdir /srv/webapp/PublishHistory/${BUILD_YM}/${VersionMajor}.${BUILD_VERSION}
rm -rf /srv/webapp/api/publish/*~

systemctl start webapp.api

第二个应用（正式应用）

先停止 应用，让 nginx 使用 backup 的webapi

looptimes=3
result_code=0
ok_status=0
for((i=0;i<=looptimes;i++))
do
    result_code=`curl -I -m 10 -o /dev/null -s -w %{http_code} 10.190.27.111`   
    if [ $result_code -eq 200 ]; then
        echo "webapp backup api deploment ok"
        sed -i "10c     server    127.0.0.1  down;" /etc/nginx/conf.d/webapp.conf
        nginx -s reload
        ok_status=1
        break
    else
        sleep 3s
    fi
done

if [$ok_status -eq 0]; then
    echo "webapp api is not alive(wait 4 $[3*looptimes]s times already down)"
fi

if [ ! -d "~/srv/webapp/PublishHistory/${BUILD_YM}" ]; then
    mkdir -p ~/srv/webapp/PublishHistory/${BUILD_YM}
fi

if [ ! -d "/srv/webapp/PublishHistory/${BUILD_YM}/${VersionMajor}.${BUILD_VERSION}" ]; then
    mkdir -p /srv/webapp/PublishHistory/${BUILD_YM}/${VersionMajor}.${BUILD_VERSION}
fi

if [ ! -d "/srv/webapp/backup" ]; then
    mkdir -p /srv/webapp/backup
fi

if [ ! -d "/srv/webapp/api/publish" ]; then
    mkdir -p /srv/webapp/api/publish
fi

mv ~/srv/webiapp/PublishHistory/${BUILD_YM}/webiapp.WebApi.zip /srv/webiapp/PublishHistory/${BUILD_YM}/webiapp.WebApi.${VersionMajor}.${BUILD_VERSION}.zip

zip -qr /srv/webiapp/backup/webiappaip.${VersionMajor}.${BUILD_VERSION}.${BUILD_YM}.bak.zip  /srv/webiapp/api/publish -x "/srv/webiapp/api/publish/Logs/*"


unzip /srv/webiapp/PublishHistory/${BUILD_YM}/webiapp.WebApi.${VersionMajor}.${BUILD_VERSION}.zip -d /srv/webiapp/PublishHistory/${BUILD_YM}/${VersionMajor}.${BUILD_VERSION}

systemctl stop webiapp.api

rm -rf /srv/webiapp/api/publish/wwwroot

mv -bf /srv/webiapp/PublishHistory/${BUILD_YM}/${VersionMajor}.${BUILD_VERSION}/*  /srv/webiapp/api/publish
chmod u+rwx /srv/webiapp/api/publish/webiapp.WebApi

rmdir /srv/webiapp/PublishHistory/${BUILD_YM}/${VersionMajor}.${BUILD_VERSION}
rm -rf /srv/webiapp/api/publish/*~

systemctl start webiapp.api

looptimes=3
result_code=0
ok_status=0
for((i=0;i<=looptimes;i++))
do
    result_code=`curl -I -m 10 -o /dev/null -s -w %{http_code} localhost`   
    if [ $result_code -eq 200 ]; then
        echo "webiapp api deploment ok"
        sed -i "10c     server    127.0.0.1;" /etc/nginx/conf.d/webiapp.conf
        nginx -s reload
        ok_status=1
        break
    else
        sleep 3s
    fi
done

if [$ok_status -eq 0]; then
    echo "webiapp api is not alive(wait 4 $[3*looptimes]s and already down)"
fi
