SVN's post-commit hook script runs after each commit (commit), and we can implement some useful features in this script, such as sending email reminders, automatically backing up repositories, automatically synchronizing code to Web servers, and more.

Here with Post-commit to achieve multi-project automatic synchronization, thinking: In the SVN version of the repository root directory to divide multiple project folders, project team members when the file is submitted, Post-commit automatically determine the project to which the file belongs, and then sync to the appropriate Web server.

Test environment configuration:

SVN server: 172.16.4.234

Project 1WEB Server: 172.16.4.235

Item 1 Code Base: Svn://172.16.4.234/project1

Project 2WEB Server: 172.16.4.236

Item 2 code base: Svn://172.16.4.234/project2

Here are the steps to proceed:

One, the Web server

The Web server acts as an SVN client, checkout a copy of the code from the SVN server to local. Note To switch to WWW user checkout, because WWW is an Apache or nginx execution User (your environment may not be the same).

Project 1WEB Server, the site root directory is/data/apps/project1:

123	shell# su wwwshell$ cd/data/apps/shell$ svn co--username zb--password 123456 Svn://172.16.4.234/project1

Project 2WEB Server, the site root directory is/data/apps/project2:

123	shell# su wwwshell$ cd/data/apps/shell$ svn co--username zb--password 123456 svn://172.16.4.234/project2

Second, configure SSH password-free access

SVN server requires no password SSH access to the Web server, convenient post-commit script ssh to the Web server to perform SVN up. Note here that the WWW user is not password-accessible because the code on the Web server is checkout by the WWW user.

Execute ssh-keygen-t RSA on the SVN server, then press ENTER all the time, generate the public key and the private key are saved in/root/.ssh/.

Then on the Web server first switch to the WWW user, establish the Authorized_keys file:

12345

[[email protected] ~]# su www[[email protected] root]$ cd[[email protected] ~]$ mkdir. Ssh[[email protected] ~]$ chmod 755 . Ssh/[[email protected] ~]$ vi. Ssh/authorized_keys

Copy the contents of the/root/.ssh/id_rsa.pub public key file on the SVN server to the Authorized_keys file. Then set the Authorized_keys file permission to 600.

1	[Email protected] ~]$ chmod Ssh/authorized_keys

Test, SVN server login Project 1WEB server:

12	[[email protected] ~]# ssh [email protected][[email protected] ~]$

Third, SVN server post-commit

Post-commit is under the hooks directory of SVN.

Post-commit Script content:

1234567891011121314151617181920212223242526272829303132333435363738394041424344454647484950515253545556

Don't forget to give Post-commit executable permissions.

Iv. Testing

In the "Project1/client" and "Project1/server" directories in Project 1, upload a "new text document. txt" separately to view the log file/var/log/svn.log:

The log shows that the file has been synced to the project 1WEB server.
