新版本svn使用gpg-agent存儲密碼-CSDN博客
svn之無法讓 SVN 存儲密碼，即使配置設置為允許_編程設計_ITGUEST
方法一：明文方式保存密碼
首次執行svn check或svn update等命令后，會在系統用戶目錄下生成.subversion目錄，并在.subversion/auth/svn.simple目錄下生成SVN用戶的配置文件，比如：cdf4a82409609b47a18c1b93ad8db39c，文件內容如下：
steven@ubuntu2204:~$ cat "~/.subversion/auth/svn.simple/cdf4a82409609b47a18c1b93ad8db39c"
K 8
passtype
V 9
gpg-agent
K 15
svn:realmstring
V 52
<https://192.168.121.240> Subversion Repository
K 8
username
V 6
steven
END修改.subversion/auth/svn.simple/cdf4a82409609b47a18c1b93ad8db39c文件，如下：
steven@ubuntu2204:~$ vi "~/.subversion/auth/svn.simple/cdf4a82409609b47a18c1b93ad8db39c"
steven@ubuntu2204:~$ cat "~/.subversion/auth/svn.simple/cdf4a82409609b47a18c1b93ad8db39c"
K 8
passtype
V 6
simple
K 15
svn:realmstring
V 52
<https://192.168.121.240:5443> Subversion Repository
K 8
username
V 6
steven
K 8
password
V 7
pwd1234
END修改說明：
1.文件中K表示關鍵字，V表示鍵值，后面的數字表示下一行字符串的長度。
2.將密碼保存方式由gpg-agent改為simple(明文)
3.添加steven用戶密碼: pwd1234
需要注意的是：若是換個SVN用戶名后這個文件會被改寫，以上手動修改的信息會被覆蓋，需要從再手動修改。
方式二：gpg-agent加密保存
gpg-agent是一個密碼管理工具，具體說明查看官網信息。
https://www.gnupg.org/
1.安裝gpg-agent：
steven@ubuntu2204:~$ sudo apt-get install gpg-agent
gpg-agent (GnuPG) 2.2.27
libgcrypt 1.8.8

2.添加環境變量：
修改shell初始化腳本，添加GPG_TTY和GPG_AGENT_INFO兩個環境變量。并使用source命令讓其立即生效。
steven@ubuntu2204:~$ vi ~/.bashrc
steven@ubuntu2204:~$ cat ~/.bashrc
... ...
export GPG_TTY=$(tty)
export GPG_AGENT_INFO=`gpgconf --list-dirs agent-socket | tr -d '\n' && echo -n ::`
steven@ubuntu2204:~$ source ~/.bashrc3.配置gpg-agent
steven@ubuntu2204:~$ vi "~/.gunpg/gpg-agent.conf"
steven@ubuntu2204:~$ cat "~/.gunpg/gpg-agent.conf"
# ╔═══════════════════════════════════════════════════════════════════════════╗

# ║ Note: ║
# ║ After changing the configuration, reload the agent: ║

max-cache-ttl 604800steven@ubuntu2204:~$ gpg-connect-agent reloadagent /bye4.刪除舊的SVN賬號信息
steven@ubuntu2204:~$ rm -rf ~/.subversion5.執行效果
steven@ubuntu2204:~$ svn update svntest
