Configuration file Intelligence Backup and restore _php tutorial

Configure file intelligence for backup and restore

Application Scenarios:
Whenever we install the same machine upgrade or update service for many, we want to back up one or more lines in the configuration file, or a data block or multiple data blocks, and the service upgrade, update, and then the corresponding backup data back to the new configuration file, in the high-volume server operation, Will waste a lot of time and energy, the following script is used to accomplish similar things.
The main functions are:
1. Back up a specified row or lines, one block or multiple blocks
2. Back up the specified individual files
3. Restore all partial backups and all backups
4. configuration file precise positioning insert "regular match"
5. configuration file Precise location Delete
6. configuration file similar to line after bulk insert
Sample configuration file for the service:

 
  
  

  
   
   
Server.config:

  
   
   
# # # #配置文件样例:

  
   
   
ser_max_connection=6000 #行

  
   
   
ser_min_connection=10

  
   
   


  
   
   
Ser_time_out=60

  
   
   
ser_time_spent=120

  
   
   


  
   
   
Server tcp_nodes{ # #块

  
   
   


  
   
   
Ser_client_ip=ipv4

  
   
   
Ser_client_len=20*n

  
   
   
Ser_client_syn=yes

  
   
   
Ser_client_ack=yes

  
   
   
}
 
  
  

The following is the code implementation of the shell script, which mainly uses the SED tool to complete the configuration editing function. This script is changed to a generic version according to the real application environment, and has not been rigorously tested, if you want to use this script, please do serious testing according to your own environment.
