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
