前言

?記錄下使用云效部署Java項目，實現java項目一鍵化自動化部署。

云效流程說明：

1.云效拉取最新git代碼后

2.進行maven編譯打包后，上傳到指定服務器目錄

3.通過shell腳本，先kill?java項目后，通過java -jar?啟動項目。

注：git代碼更新需要手動更新?

?添加服務連接-獲得阿里云授權

部署腳本配置：?

# 創建必要的目錄
mkdir -p /usr/local/nginx/app
mkdir -p /usr/local/nginx/app/mall-im_turn_java
mkdir -p /usr/local/nginx/app/mall-im_turn_java/jar

mkdir -p /usr/local/nginx/app/mall-im_turn_java/jar/logs
# 解壓文件
tar zxvf /usr/local/nginx/app/mall-im_turn_java/mall_release.tgz -C /usr/local/nginx/app/mall-im_turn_java/jar
# 執行sh腳本
cd ?/usr/local/nginx/app/mall-im_turn_java/jar
bash /usr/local/nginx/app/mall-im_turn_java/jar/start_run.sh?

#進入此目錄

cd???/usr/local/nginx/app/mall-im_turn_java/jar?

注：

1.linux服務器需要安裝jdk才可正常啟動運行??

2.git代碼-下載的代碼主目錄一定要有pom.xml文件否則不適配

3.git代碼每次使用流水線運行部署-需要手動更新git最新代碼，更新成功后再進行部署
