本文以以下需求为背景,介绍详细的做法:
需在同一台服务器同时部署两个不同的 Github 仓库(对 Bitbucket 等 git 服务同样适用)
root 用户可在远程登录 SSH 后附上预期的 SSH Key 进行 git 命令操作
nginx 用户进程(如 php-fpm)可在进程内附上预期的 SSH Key 进行 git 命令操作
以 root 身份登录服务器,为 root 用户和 nginx 用户分别生成 SSH Key。
仓库 1:
$ ssh-keygen -b 2048 -t rsa -f "~/.ssh/id_rsa_github_myrepo1"
$ sudo -u nginx ssh-keygen -b 2048 -t rsa -C "nginx@localhost" -f "/var/lib/nginx/.ssh/id_rsa_github_myrepo1"
仓库 2:
$ ssh-keygen -b 2048 -t rsa -f "~/.ssh/id_rsa_github_myrepo2"
$ sudo -u nginx ssh-keygen -b 2048 -t rsa -C "nginx@localhost" -f "/var/lib/nginx/.ssh/id_rsa_github_myrepo2"
此处的 nginx 用户的主目录因操作系统不同而拥有不同的路径,经测试 CentOS 系的操作系统可能值为:
"/var/lib/nginx"
"/var/cache/nginx"
"/usr/share/nginx"
之其一,请读者执行
sudo -u nginx ssh-keygen
查看并以实际路径为准,替换本文中的对应命令的路径。如:
[root@localhost]# sudo -u nginx ssh-keygen
Generating public/private rsa key pair.
Enter file in which to save the key (/var/cache/nginx/.ssh/id_rsa):
此处的 nginx 用户的主目录为 "/var/cache/nginx"。
将生成好的 SSH Key 的公钥部分添加到两个 Github 仓库设置的 Deploy Keys(部署密钥)中。
仓库 1:
$ cat "~/.ssh/id_rsa_github_myrepo1.pub"
$ cat "/var/lib/nginx/.ssh/id_rsa_github_myrepo1.pub"
仓库 2:
$ cat "~/.ssh/id_rsa_github_myrepo2.pub"
$ cat "/var/lib/nginx/.ssh/id_rsa_github_myrepo2.pub"
编辑用户的 SSH 配置文件,并指定主机的详细自定义配置。
root 用户:
$ nano "~/.ssh/config"
Host github.com-myrepo1
HostName github.com
User git
IdentityFile ~/.ssh/id_rsa_github_myrepo1
Host github.com-myrepo2
HostName github.com
User git
IdentityFile ~/.ssh/id_rsa_github_myrepo2
nginx 用户:
$ nano "/var/lib/nginx/.ssh/config"
Host github.com-myrepo1
HostName github.com
User git
IdentityFile /var/lib/nginx/.ssh/id_rsa_github_myrepo1
Host github.com-myrepo2
HostName github.com
User git
IdentityFile /var/lib/nginx/.ssh/id_rsa_github_myrepo2
完成了上述步骤,读者现在可以在 root 或 nginx 用户登录或以其运行的进程中执行 git 命令,并且会自动附上指定的 SSH Key。例如:
$ git clone git@github.com-myrepo1:tommy/myrepo1.git "/var/www/myrepo1"
$ git clone git@github.com-myrepo2:tommy/myrepo2.git "/var/www/myrepo2"
<?
header( ‘Content-type: text/text‘ );
exit( shell_exec( ‘cd /var/www/myrepo1; git pull origin master 2>&1‘ ) );
exit( shell_exec( ‘cd /var/www/myrepo2; git pull origin master 2>&1‘ ) );
git remote set-url <name> <newurl>
git remote set-url origin git@github.com-myrepo1:tommy/myrepo1.git
git remote set-url origin git@github.com-myrepo2:tommy/myrepo2.git
删掉,重新生成即可。
rm -f ~/.ssh/know_hosts
ssh -T git@github.com
Hi Anonymous! You‘ve successfully authenticated, but Github.com does not provide shell access.
Bad owner or permissions
sudo chmod 600 ~/.ssh/config
