Shell Programming-project Deployment (optimization)

In the actual work of small and medium-sized to encounter a problem that is when I go to operate the deployment script, another person can also operate, this how can do, and then the small part of the thought to re-optimize the code, add a process lock

The usual, first comb the idea:

At the same time, the script can only allow one person to operate, that is to say

As long as the script executes to create a file, as long as the file exists, then let the script exit, and prompt "script is really running", the script is completed, delete the created file

The code is as follows

　　

  
 

   
  

  
  #!/bin/bash
   
  

  
# 功能：打包代码
   
  

  
# 名称：deploy.sh

# 日志功能
   
  

  
write_log(){

buzhou="$1"
   
  

  
echo " ${LOG_DATE}  ${LOG_TIME}$0${buzhou}" >> /data/logs/deploy.log
   
  

  
}
