1、创建工作目录
创建jar
部署的目录,并且将jar
上传到该目录下
1
|
mkdir -p /home/java-server/test-demo |
2、创建启动脚本
进入jar
目录:
1
|
cd /home/java-server/test-demo |
创建脚本文件:
1
|
vim start.sh |
启动脚本内容:
1
2
3
4
5
6
7
8
9
10
11
12
13
14
|
#!/bin/sh export LANG= "en_US.UTF-8" cd /home/java-server/test-demo runMessage=`ps aux | grep \`cat pidfile.txt\`` projectStartCommand= "/usr/local/java/jdk1.8.0_131/bin/java -jar xxx.jar" if [[ $runMessage == *$projectStartCommand* ]] then echo "Application has starting ,restarting..." kill -9 `cat pidfile.txt` nohup /usr/local/java/jdk1.8.0_131/bin/java -jar xxx.jar -java.tmp.dir=/home/java-server/test-demo/temp >/dev/ null 2>&1 & echo $! > pidfile.txt else echo "Application has stopped ,starting..." nohup /usr/local/java/jdk1.8.0_131/bin/java -jar xxx.jar -java.tmp.dir=/home/java-server/test-demo/temp >/dev/ null 2>&1 & echo $! > pidfile.txt fi |
- 脚本中
/home/java-server/test-demo
就是jar包
所在的,可以根据实际情况定。 xxx.jar
为实际的jar
包名称。/usr/local/java/jdk1.8.0_131/bin/java
为jdk环境所在路径。
3、创建停止脚本
进入jar
目录:
1
|
cd /home/java-server/test-demo |
创建脚本文件:
vim stop.sh
停止脚本内容:
#!/bin/sh cd /home/java-server/test-demo PID=$(cat pidfile.txt) if [ ${PID} ]; then echo 'Application is stpping...' echo kill $PID DONE kill $PID else echo 'Application is already stopped...' fi
进入system:
# 进入system cd /usr/lib/systemd/system/
创建自启脚本:
vim xxx.service
xxx.service为脚本的名称,一般来就是jar包前缀名称一致,比如:test-demo.service
内容如下:
[Unit] Description=xxx After=network.target [Service] Type=forking ExecStart=/home/java-server/test-demo/start.sh ExecStop=/home/java-server/test-demo/stop.sh PrivateTmp=true [Install] WantedBy=multi-user.target
- Description:描述,一般为项目名称
- ExecStart:开启脚本位置
- ExecStop:停止脚本位置
设置脚本权限:
# 自启文件 chmod 777 xxx.service # 启动文件 chmod 777 /home/java-server/test-demo/start.sh # 停止文件 chmod 777 /home/java-server/test-demo/stop.sh
systemctl daemon-reload systemctl enable xxx.service
启动|停止命令:
# 启动 systemctl start xxx # 停止 systemctl stop xxx
xxx
就是xxx.service
的前缀。
