项目jar包启动的命令

项目jar包启动的命令

当我们在linux系统里某个路径下创建了许多个jar包的文件夹后，我们可以通过 java -jar 命令脚本可以快速的启动我们的jar包以及实现全部启动及全部结束jar进程。

1.在linux系统中jar包存放位置

/opt/services/providers路径下是各个jar包存放的文件夹，同时将service.sh文件放入在该路径下，通过启动命令：
./service.sh start channeldemand 即可启动 YL-B-Channel-Demand-Provider.jar 包
channeldemand是 YL-B-Channel-Demand-Provider.jar在service.sh中配置的别名

如果需要启动该目录下的所有jar包，通过命令即可启动所有jar包：
./service.sh start all

2.service.sh中启动jar包具体的配置

只需要更改1.程序代码数组：每个jar包起别名 2.程序名称数组:具体每个jar包具体的名称 3.jar包数组:具体的jar包 4.jar包路径数组：jar包所在的路径地址。5.PROJECTDIR属性：具体的jar包文件夹所在路径，/opt/services/providers/KaTeX parse error: Expected ‘}’, got ‘EOF’ at end of input: {PATHS[i]}。
修改这5个地方即可实现jar包配置。

3. 通过 nohup java -jar jar名 & 启动jar包

进入到jar包所在的文件夹下通过
tail -fn 200 nohup.out 可以查看相关jar包的启动日志。

java -jar -XX:MetaspaceSize=256m -XX:MaxMetaspaceSize=256m -Xms512m -Xmx512m -Xmn256m -Xss256k -XX:SurvivorRatio=8 -XX:+UseConcMarkSweepGC YL-B-Channel-Demand-Provider.jar &
