2. prepare to pull the source code from the company's svn server. then an error is reported.
"Host key verification failed"
It may have been a long time ago. The ssh Key has already been repeated and modified. it is an old key on the book.
So
# Vim/root/. ssh/known_hosts
Delete all keys in ggVG d: wq all selected delete save quit
Then continue to pull

3. svn checkout url/path
I suddenly found that I couldn't remember my password... I don't seem to know which one it is.
Fortunately, there is a working machine that can be used frequently. so I checked the files of svn's account information.
# Ls/root/. subversion/auth/svn. simple
F41a29d3154438aeff11d37c97ab5dd3
# Cat/root/. subversion/auth/svn. simple/f41a29d3154438aeff11d37c97ab5dd3
You can see the svn password in plain text. then let's go to svn checkout.
