这是我为执行此操作而编写的 bash 脚本。它将克隆任何新分支,更新任何现有分支,并删除不再存在的分支。以下是“有效”的说明;你可以选择让事情变得更安全,但如果你的服务器只能在你的局域网上访问,这就足够了。我有一个 cron 作业设置,它每 30 分钟在服务器上运行一次。要将 cron 作业设置为以 root 身份运行,请运行:
sudo crontab -e
然后粘贴这些内容:
*/30 * * * * /usr/local/bin/opengrok_index.sh
然后写入并关闭:
:wq
您将需要安装脚本用于输入 ssh 密钥密码的“expect”。这两个命令之一将根据您使用的 linux 操作系统起作用:
sudo yum install expect
sudo apt-get install expect
然后在 /usr/local/bin/opengrok_index.sh 创建一个文件:
sudo vi /usr/local/bin/opengrok_index.sh
接下来,粘贴脚本的内容(从本文底部开始),并根据您的系统更改顶部的变量。接下来,更改权限,以便只有 root 可以读取它(其中有密码):
sudo chmod 700 /usr/local/bin/opengrok_index.sh
在期望 cron 作业正常工作之前,您可能希望手动测试运行脚本并使其正常工作。这是我为特定设置编写的特定脚本,因此您可能需要放入一些 echo 语句并进行一些调试以使其正常工作:
sudo /usr/local/bin/opengrok_index.sh
补充笔记:
- 此脚本通过 SSH(不是 HTTPS)登录到 GIT。因此,您的 GIT_USER 必须存在于系统上,并且在 /home/user/.ssh/id_rsa 下有一个可以访问 GIT 存储库的 SSH 密钥。这是标准的 GIT 登录内容,所以我不会在这里详细介绍。脚本会在提示时输入 GIT_USER_SSH_PASSWORD
- 该脚本将所有文件签出为 GIT_USER,因此您可能需要将您的 CHECKOUT_LOCATION “chown”给该用户
脚本:
#!/bin/bash
SUDO_PASSWORD="password"
CHECKOUT_LOCATION="/var/opengrok/src/"
GIT_PROJECT_NAME="Android"
GIT_USER="username"
GIT_USER_SSH_PASSWORD="password"
GIT_URL="yourgit.domain.com"
OPENGROK_BINARY_FILE="/usr/local/opengrok-0.12.1.6/bin/OpenGrok"

exp_continue
}
\"*Enter passphrase for key*\" {
