验证

[root@controller ~]# openstack network agent list


八、安装dashboard

controller节点

安装软件包

[root@controller ~]# yum install -y openstack-dashboard

编辑配置文件/etc/openstack-dashboard/local_settings

OPENSTACK_HOST = "controller"

ALLOWED_HOSTS = ['*', 'localhost']

SESSION_ENGINE = 'django.contrib.sessions.backends.cache'

CACHES = {

'default': {

'BACKEND': 'django.core.cache.backends.memcached.MemcachedCache',

'LOCATION': 'controller:11211',

}

}

OPENSTACK_KEYSTONE_URL = "http://%s:5000/v3" % OPENSTACK_HOST

OPENSTACK_KEYSTONE_MULTIDOMAIN_SUPPORT = True

OPENSTACK_API_VERSIONS = {

"identity": 3,

"image": 2,

"volume": 2,

}

OPENSTACK_KEYSTONE_DEFAULT_DOMAIN = "Default"

OPENSTACK_KEYSTONE_DEFAULT_ROLE = "user"

OPENSTACK_NEUTRON_NETWORK = {

...

'enable_router': False,

'enable_quotas': False,

'enable_distributed_router': False,

'enable_ha_router': False,

'enable_lb': False,

'enable_firewall': False,

'enable_vpn': False,

'enable_fip_topology_check': False,

}

编辑/etc/httpd/conf.d/openstack-dashboard.conf

WSGIApplicationGroup %{GLOBAL}

启动服务

[root@controller ~]# systemctl restart httpd.service memcached.service

九、验证

浏览器打开192.168.253.188/dashboard




3、配置nginx反向代理tomcat，并使用redis实现会话保持。


环境：

一台nginx+redis ：192.168.2.198

一台tomcat1：192.168.2.197

一台tomcat2：192.168.2.199

一、2台Tomcat配置java环境及发布目录

1、jdk安装

#rpm -ivh jdk-8u151-linux-x64.rpm

2、tomcat下载、解压

tomcat 下载地址：http://tomcat.apache.org/

#tar xf apache-tomcat-7.0.78.tar.gz -C /usr/local/

#cd /usr/local/

#ln -s apache-tomcat-7.0.78 tomcat

3、配置path环境变量

#vim /etc/profile.d/tomcat.sh

export CATALINA_BASE=/usr/local/tomcat

export PATH=$CATALINA_BASE/bin:$PATH

#chmod +x /etc/profile.d/tomcat.sh # 赋予可执行权限

#source /etc/profile.d/tomcat.sh

4、创建测试网页的发布目录

#mkdir /usr/local/tomcat/webapps/test/

5、创建测试页面(197上创建tomcatA ,199上创建tomcatB)

[root@localhost conf]#vim /usr/local/tomcat_a/webapps/test/index.jsp

<%@ page language="java" %>

<html>

<head><title>TomcatA</title></head>

<body>

<h1><font color="red">TomcatA.linuxinfo.top</font></h1>

<tablealign="centre" border="1">

<tr>

<td>SessionID</td>

<% session.setAttribute("linuxinfo.top","linuxinfo.top");%>

<td><%=session.getId() %></td>

</tr>

<tr>

<td>Createdon</td>

<td><%=session.getCreationTime() %></td>

</tr>

</table>

</body>

</html>

6、分别启动tomcat

#catalina.sh start                #可也用全路径/usr/local/tomcat/bin/startup.sh

7、访问192.168.2.197，测试如下，查看session ID

二、配置nginx负载均衡

#vim /usr/local/nginx/conf/nginx.conf

upstream tomcat{

server 192.168.2.197:8080;

server 192.168.2.199:8080;

}

server {

listen 80;

server_name localhost;

location / {

proxy_pass http://192.168.2.198；

}

}

三、Redis 配置

1、下载相关软件包，放在 /usr/local/tomcat/lib。

asm-5.2.jar

kryo-3.0.3.jar

kryo-serializers-0.45.jar

memcached-session-manager-2.3.2.jar

memcached-session-manager-tc8-2.3.2.jar

minlog-1.3.1.jar

msm-kryo-serializer-2.3.2.jar

objenesis-2.6.jar

reflectasm-1.11.9.jar

spymemcached-2.12.3.jar

jedis.jar

2、安装Redis

# yum install redis

# vim /etc/redis.conf

bind 0.0.0.0

# systemctl start redis

3、编辑Redis配置文件

#vim /usr/local/tomcat/conf/context.xml

<Context>

...

<Manager className="de.javakaffee.web.msm.MemcachedBackupSessionManager"

memcachedNodes="redis://192.168.2.198:6379"

sticky="false"

sessionBackupAsync="false"

lockingMode="uriPattern:/path1|/path2"

requestUriIgnorePattern=".*\.(ico|png|gif|jpg|css|js)$"

transcoderFactoryClass="de.javakaffee.web.msm.serializer.kryo.KryoTranscoderFactory"

/>

</Context>

4、测试访问代理服务192.168.2.198，查看session ID 保持不变，实现会话保持
