确认权限

[root@controller1 ~]# ll /etc/keystone/keystone.conf

-rw-r----- 1 root keystone 73642 Feb 21 15:42 /etc/keystone/keystone.conf

[root@controller1 ~]# chown root:keystone /etc/keystone/keystone.conf

[root@controller1 ~]# chmod 640 /etc/keystone/keystone.conf

同步Keystone数据库

[root@controller1 ~]# su -s /bin/sh -c "keystone-manage db_sync" keystone

初始化Fernet keys

[root@controller1 ~]# keystone-manage fernet_setup --keystone-user keystone --keystone-group keystone

配置Apache Http服务

1、三个节点配置 /etc/httpd/conf/httpd.conf

[root@controller1 ~] # vim /etc/httpd/conf/httpd.conf

ServerName controller1

Listen 8080

[root@controller2 ~]# vim /etc/httpd/conf/httpd.conf

ServerName controller2

Listen 8080

[root@controller3 ~]# vim /etc/httpd/conf/httpd.conf

ServerName controller3

Listen 8080

2、[root@controller1 ~]# vim /etc/httpd/conf.d/wsgi-keystone.conf

WSGIDaemonProcess keystone-public processes=5 threads=1 user=keystone group=keystone display-name=%{GROUP}

WSGIProcessGroup keystone-public

WSGIScriptAlias / /usr/bin/keystone-wsgi-public

WSGIApplicationGroup %{GLOBAL}

WSGIPassAuthorization On

ErrorLogFormat "%{cu}t %M"

ErrorLog /var/log/httpd/keystone-error.log

CustomLog /var/log/httpd/keystone-access.log combined

Require all granted

</Directory>

</VirtualHost>

WSGIDaemonProcess keystone-admin processes=5 threads=1 user=keystone group=keystone display-name=%{GROUP}

WSGIProcessGroup keystone-admin

WSGIScriptAlias / /usr/bin/keystone-wsgi-admin

WSGIApplicationGroup %{GLOBAL}

ErrorLogFormat "%{cu}t %M"

ErrorLog /var/log/httpd/keystone-error.log

CustomLog /var/log/httpd/keystone-access.log combined

Require all granted

</Directory>

</VirtualHost>

将wsgi-keystone.conf复制到 controller2和controller3

3、启动apache

# systemctl enable httpd.service

# systemctl start httpd.service

优质分享App

近一个月的开发和优化，本站点的第一个app全新上线。该app采用极致压缩，本体才4.36MB。系统里面做了大量数据访问、缓存优化。方便用户在手机上查看文章。后续会推出HarmonyOS的适配版本。

Spring

Spring框架（Spring Framework）是由Rod Johnson于2002年提出的开源Java企业级应用框架，旨在通过使用JavaBean替代传统EJB实现方式降低企业级编程开发的复杂性。该框架基于简单性、可测试性和松耦合性设计理念，提供核心容器、应用上下文、数据访问集成等模块，支持整合Hibernate、Struts等第三方框架，其适用范围不仅限于服务器端开发，绝大多数Java应用均可从中受益。

Rocky Linux

Rocky Linux（中文名：洛基）是由Gregory Kurtzer于2020年12月发起的企业级Linux发行版，作为CentOS稳定版停止维护后与RHEL（Red Hat Enterprise Linux）完全兼容的开源替代方案，由社区拥有并管理，支持x86_64、aarch64等架构。其通过重新编译RHEL源代码提供长期稳定性，采用模块化包装和SELinux安全架构，默认包含GNOME桌面环境及XFS文件系统，支持十年生命周期更新。

Sublime Text

Sublime Text具有漂亮的用户界面和强大的功能，例如代码缩略图，Python的插件，代码段等。还可自定义键绑定，菜单和工具栏。Sublime Text 的主要功能包括：拼写检查，书签，完整的 Python API ， Goto 功能，即时项目切换，多选择，多窗口等等。Sublime Text 是一个跨平台的编辑器，同时支持Windows、Linux、Mac OS X等操作系统。
