# 服务器部署脚本
|
||
# doc:
|
||
# 1.在Idea中下载安装阿里云Alibaba Cloud插件
|
||
# 2.使用Ecs的AccessKeyId和AccessSecurity登录，服务器信息里有具体密码
|
||
# 3.在upload选项中选择需要上传的jar包，location默认为根路径/，
|
||
# command中输入脚本运行命令：sh /deploy.sh stopUpdateStart /usr/local/zapp/user/zapp-user-1.0.jar /usr/local/zapp/user notPrint
|
||
# 注：
|
||
# /deploy.sh脚本包括了，启动服务器，优雅停止java服务器，更新文件，重新启动服务器的脚本，对应四个命令：start|stop|update|stopUpdateStart。
|
||
# 其中stopUpdateStart会按照顺序执行，stop，update，start命令。
|
||
|
||
# usage:
|
||
# sh deploy.sh start /usr/local/zapp/gateway/zapp-gateway-1.0.jar /usr/local/zapp/gateway
|
||
# sh deploy.sh stop gateway
|
||
# sh deploy.sh update /usr/local/zapp/gateway/zapp-gateway-1.0.jar
|
||
# sh deploy.sh stopUpdateStart /usr/local/zapp/gateway/zapp-gateway-1.0.jar /usr/local/zapp/gateway
|
||
# start启动服务器，/usr/local/zapp/gateway/zapp-gateway-1.0.jar是jar包的绝对路径，/usr/local/zapp/gateway是日志的输出路径
|
||
# stop关闭服务器，会使用jps | grep gateway，抓取需要关闭的java进程
|
||
# update更新jar包，默认会使用根路径/zapp-gateway-1.0.jar下的jar包去更新/usr/local/zapp/gateway/zapp-gateway-1.0.jar路径的jar包
|
||
# stopUpdateStart，按顺序执行命令stop，update，start
|
||
|
||
# 相关参数命令
|
||
# java -XX:+PrintFlagsInitial，查看jvm全部参数的默认值
