Cyrus SASL authentication is available.
3 Create a suitable repository for storing svn
mkdir -p /home/svn/svnrepos
4 Create a repository svnadmin create /home/svn/svnrepos
5 Then go to the created repository address to create a repository cd /home/svn/svnrepos
There will be the following:
[root@VM_137_37_centos svnrepos]# ls -1
README.txt
conf
db
format
hooks
locks
6 Then enter the conf file to modify the content cd conf/
authz file is the permission control file
passwd is the account password file
svnserve.conf SVN service configuration file
7 Change password
### This file is an example password file for svnserve.
### Its format is similar to that of svnserve.conf. As shown in the
### example below it contains one section labelled [users].
### The name and password for each user follow, one account per line.
[users]
# harry = harryssecret
# sally = sallyssecret
quwenzhe=123456
Add a user password
8 Modify permissions
- [/]
- quwenzhe=rw
Let it have read and write permissions. If you have special permissions, you need to find it on svn.
9 Modify the svnserve.conf file vi svnserve.conf
anon-access = read #Anonymous users can read
auth-access = write #Authorized users can write
password-db = passwd #Which file is used as the account file
authz-db = authz # Which file is used as the permission file
realm = /home/svn /svnrepos # Authentication space name, the directory where the repository is located
Note that there can be no space in front of the comment after removing the comment, otherwise an error will be reported when executing
10 start svn
svnserve -d -r /var/svn/svnrepos (stop SVN command killall svnserve )
11 Then you can go to test on windows
Just enter the address of svn, you can leave the content behind 
and click OK to let it enter the account and password just set on passwd.
I also encountered a lot of problems when I first built it. For example, when editing the passwd file, there have been problems because of the unfamiliarity with the liunx system, so please follow the steps strictly when using it. Writing it out is also to consolidate yourself, and spread it so that everyone can use it correctly. If you have any questions, you can communicate at any time.
