我一直在寻找说明，但找不到以下内容的完整说明集：

在阅读了许多帖子并进行了一些试验和错误之后，我想出了下面列出的步骤。 我想知道是否有遗漏或错误？？
1- 在 NFS 中创建目录：
mkdir /nfs_dir/data -p
mkdir /nfs_dir/logs -p
chmod 700 /nfs_dir/data
chmod 750 /nfs_dir/logs
chown nisuser:nisgroup ...
2- 本地驱动器中的 Crate 运行目录：
sudo mkdir /var/run/mariadb
sudo chown nisuser:nisgroup /var/run/mariadb
sudo chmod 755 /var/run/mariadb
3- 安装 MariaDB
来自 download.mariadb.org 的说明
4- sudo service mysql stop
5- 在 NFS 中创建数据库文件： sudo mysql_install_db --user=nisuser --datadir/nfs_dir/data
6- 编辑 MariaDB 配置（下面只显示编辑过的行，其他保持默认）：
sudo vi …使用詹金斯2.169

------------------------------- …我最近升级到 Jenkins 2.192，我的应用程序开始失败并出现以下错误：
HTTP Error 403: No valid crumb was included in the request
Reason: No valid crumb was included in the request
降级到 Jenkins 2.189 后我没有看到问题。我没有看到 Jenkins 2.189、2.190、2.191 的问题。我遇到了 Jenkins 2.192 的问题（也见于 2.196）
2.191 和 2.192 之间发生了一些变化，导致我观察到的失败。
我正在尝试安装mysqclient，但是在具有Python 3.7.0的Ubuntu 18.04 LTS中尝试“ apt-get install libmariadbclient-dev”时遇到错误。
我该如何进行这项工作？谢谢。
