PM2 runs json file to start node project and pm2-web installation
Define the run configuration file
We can predefine a configuration file and then work out how to run it. For example, we can define a file app.json, which reads as follows:
[root@jenkins-master linux]# cat app.json { "apps":[ { "name": "service-sk_platform_professional_dev", "cwd": "/data/source/service-sk_platform_professional_dev/publish/", "script": "/data/source/service-sk_platform_professional_dev/publish/service/server.js", "log_date_format": "YYYY-MM-DD HH:mm Z", "error_file": "/data/pm2-log/errlogs/service-sk_platform_professional_dev-err.log", "out_file": "/data/pm2-log/outlogs/service-sk_platform_professional_dev-out.log", "pid_file": "/data/pm2-log/outlogs/service-sk_platform_professional_dev.pid", "instances": 1, "node_args": "--inspect=0.0.0.0:33111", "min_uptime": "20s", "max_restarts": 50, "watch": false, "merge_logs": true, "exec_interpreter": "node", "exec_mode": "fork", } ] }
[root@node-44 ~]# cat app.json { "apps":[ { "name": "sk_service_calculate_convert_dev", "cwd": "/data/source/sk_service_calculate_convert_dev/publish/", "script": "/data/source/sk_service_calculate_convert_dev/publish/service/server.js", "log_date_format": "YYYY-MM-DD HH:mm Z", "error_file": "/data/pm2-log/errlogs/sk_service_calculate_convert_dev-err.log", "out_file": "/data/pm2-log/outlogs/sk_service_calculate_convert_dev-out.log", "pid_file": "/data/pm2-log/outlogs/sk_service_calculate_convert_dev.pid", "instances": 1, "min_uptime": "20s", "max_restarts": 50, "watch": false, "merge_logs": true, "exec_interpreter": "node", "exec_mode": "fork", },{ "name": "sk_service_calculate_convert_dev2", "cwd": "/data/source/sk_service_calculate_convert_dev/publish/", "script": "/data/source/sk_service_calculate_convert_dev/publish/service/server.js", "args": "'debug' '12345'", "log_date_format": "YYYY-MM-DD HH:mm Z", "error_file": "/data/pm2-log/errlogs/sk_service_calculate_convert2_dev-err.log", "out_file": "/data/pm2-log/outlogs/sk_service_calculate_convert2_dev-out.log", "pid_file": "/data/pm2-log/outlogs/sk_service_calculate_convert2_dev.pid", "instances": 1, "min_uptime": "20s", "max_restarts": 50, "watch": false, "merge_logs": true, "exec_interpreter": "node", "exec_mode": "fork", },{ "name": "sk_service_calculate_convert_dev3", "cwd": "/data/source/sk_service_calculate_convert_dev/publish/", "script": "/data/source/sk_service_calculate_convert_dev/publish/service/server.js", "args": "'debug' '12344'", "log_date_format": "YYYY-MM-DD HH:mm Z", "error_file": "/data/pm2-log/errlogs/sk_service_calculate_convert3_dev-err.log", "out_file": "/data/pm2-log/outlogs/sk_service_calculate_convert3_dev-out.log", "pid_file": "/data/pm2-log/outlogs/sk_service_calculate_convert3_dev.pid", "instances": 1, "min_uptime": "20s", "max_restarts": 50, "watch": false, "merge_logs": true, "exec_interpreter": "node", "exec_mode": "fork", },{ "name": "sk_service_calculate_convert_dev4", "cwd": "/data/source/sk_service_calculate_convert_dev/publish/", "script": "/data/source/sk_service_calculate_convert_dev/publish/service/server.js", "args": "'debug' '12343'", "log_date_format": "YYYY-MM-DD HH:mm Z", "error_file": "/data/pm2-log/errlogs/sk_service_calculate_convert4_dev-err.log", "out_file": "/data/pm2-log/outlogs/sk_service_calculate_convert4_dev-out.log", "pid_file": "/data/pm2-log/outlogs/sk_service_calculate_convert4_dev.pid", "instances": 1, "min_uptime": "20s", "max_restarts": 50, "watch": false, "merge_logs": true, "exec_interpreter": "node", "exec_mode": "fork", } ] }
for (int i = 0;i<"${node_number}".toInteger();i++){ Integer nodeport=10000+i sh "cat /data/ansible/playbook/linux/linux_app.json |sed -e 's/sourcepath_node_Jenvironment/${projectname}_${environment}_${i}/g' -e 's/sourcepath_Jenvironment/${projectname}_${environment}/g' -e 's/process_mode/${process_mode}/g' -e 's/node_port/${nodeport}/g' >>${WORKSPACE}/publish/app.json" sh(script: "echo -n ',\r\n' >>${WORKSPACE}/publish/app.json") }
- Then you can run the App by running it.
