Linux下用SVN进行更新等操作时，总是提示输入用户名和密码，很不方便。因此搜了下解决办法，总结如下：
打开SVN配置文件：
vim /home/<user>/.subversion/config
找到如下代码：
### Set store-passwords to \'no\' to avoid storing passwords in the
### auth/ area of your config directory. It defaults to \'yes\',
### but Subversion will never save your password to disk in
### plaintext unless you tell it to (see the \'servers\' file).
### Note that this option only prevents saving of *new* passwords;
### it doesn\'t invalidate existing passwords. (To do that, remove
### the cache files by hand as described in the Subversion book.)
# store-passwords = no
将store-passwords = no这行更改为：
store-passwords = yes
这样在下次进行SVN操作时就不用再输入用户名和密码了。
