ubuntu下geoserver集群配置

安装tomcat

下载apache-tomcat-8.5.34.tar.gz并解压，tar -zxvf apache-tomcat-8.5.34.tar.gz

复制解压后的tomcat到安装目录，cp -r apache-tomcat-8.5.34 /opt/tomcat/tomcat8-geo3

/etc/systemd/system/下新建service文件，tomcat8-geo3.service文件来管理Tomcat 进程

内容如下：

[Unit]
Description=Tomcat8-geo3
After=syslog.target network.target remote-fs.target nss-lookup.target

[Service]
Type=forking
Environment="JAVA_HOME=/usr/java/jdk1.8.0_181" "JRE_HOME=/usr/java/jdk1.8.0_181/jre"
PIDFile=/home/arcgis/tomcat/tomcat8-geo3/tomcat.pid
Environment=CATALINA_PID=/home/arcgis/tomcat/tomcat8-geo3/tomcat.pid
Environment=CATALINA_HOME=/home/arcgis/tomcat/tomcat8-geo3
Environment=CATALINA_BASE=/home/arcgis/tomcat/tomcat8-geo3
ExecStart=/home/arcgis/tomcat/tomcat8-geo3/bin/startup.sh
ExecReload=/bin/kill -s HUP $MAINPID
ExecStop=/bin/kill -s QUIT $MAINPID
PrivateTmp=true

[Install]
WantedBy=multi-user.target

• [Unit] 表示这是基础信息
  • Description 是描述
  • After 是在那个服务后面启动，一般是网络服务启动后启动
• [Service] 表示这里是服务信息
  • Type 是服务类型
  • PIDFile 是服务的pid文件路径， 开启后，必须在tomcat的bin/catalina.sh中加入CATALINA_PID参数
  • ExecStart 是启动服务的命令
  • ExecReload 是重启服务的命令
  • ExecStop 是停止服务的指令
• [Install] 表示这是是安装相关信息
• WantedBy 是以哪种方式启动：multi-user.target表明当系统以多用户方式（默认的运行级别）启动时，这个服务需要被自动运行。

保存文件，刷新配置，让systemctl能识别
sudo systemctl daemon-reload

修改端口号
lsof -i:8085查看端口是否被占用

开启端口
ufw allow 8085

启动tomcat，并查看tomcat状态：

systemctl start tomcat8-geo3
systemctl status tomcat8-geo3

允许开机自动启动：
sudo systemctl enable tomcat8-geo3

部署节点

配置tomcat

• 在tomcat/bin目录下，新建文件setenv.sh，内容如下，cluster的配置文件生成目录

JAVA_OPTS="-server -XX:PermSize=512M -XX:MaxPermSize=1024m -Xms1024M -Xmx1024M -XX:MaxNewSize=256m"
JAVA_OPTS="$JAVA_OPTS -DCLUSTER_CONFIG_DIR=/DataDisk/iserver/iserver_data_dir/cluster/clusterConfig3"

Geoserver版本及依赖

geoserver-2.16.0
geoserver-2.16-SNAPSHOT-jms-cluster-plugin
geoserver-2.16-SNAPSHOT-activeMQ-broker-plugin

部署

• 复制geoserver.war到tomcat的webapps下
• 复制activeMQ-broker-plugin.zip的war(双击zip文件时有时看不到war文件，但是war文件存在，直接解压即可)到geoserver.war同目录下，启动容器
• jms-cluster-plugin.zip解压，复制里面全部的jar包到geoserver的WEB-lib目录下，然后重启geoserver服务
• 删除activemqBroker-2.16-SNAPSHOT/WEB-INF/classes下的ApplicationContext.xml和standalone-broker.properties
• 在cluster目录下，修改cluster.properties，内容如下：

#
#Wed Mar 25 15:13:04 CST 2020
toggleSlave=true
topicName=VirtualTopic.geoserver
connection=enabled
brokerURL=tcp\://127.0.0.1\:61616
durable=true
xbeanURL=./broker.xml
toggleMaster=true
embeddedBroker=enabled
CLUSTER_CONFIG_DIR=/DataDisk/iserver/iserver_data_dir/cluster/clusterConfig3
embeddedBrokerProperties=embedded-broker.properties
connection.retry=10
instanceName=6bd9d6b2-1993-4020-ab91-02054e120040
readOnly=disabled
group=geoserver-cluster
connection.maxwait=10000

• 修改同目录下的embedded-broker.properties，内容如下：

## JMX settings (can be overridden by env vars)
## For more information, see: http://activemq.apache.org/jmx.html
# enable/disable broker jmx
activemq.jmx.useJmx=false
# set the JMX connector port
activemq.jmx.port=1098
# set the JMX connector host
activemq.jmx.host=localhost
# enable the JMX connector
activemq.jmx.createConnector=false

## broker settings
# set the base path of the temporary broker dir
# this is also used as persistence base dir  
#activemq.base=./

## configuring the embedded broker
# connects the server via native I/O socket to the local network broadcast using an automatic assigned port 
# maximumConnections and wireFormat.maxFrameSize are added to avoid ddos attacks
activemq.transportConnectors.server.uri=nio://127.0.0.1:61616?maximumConnections=1000&wireFormat.maxFrameSize=104857600&jms.useAsyncSend=true&transport.daemon=true&trace=true

## the broker performs discovery using the following protocol:
# multicast on default network
activemq.transportConnectors.server.discoveryURI=multicast://224.1.1.3:6255

## persistence settings and system usage
## The systemUsage controls the maximum amount of space the broker will 
## use before slowing down producers. 
## For more information, see: http://activemq.apache.org/producer-flow-control.html
# enable/disable persistence
activemq.broker.persistent=true
# heap memory usage
activemq.broker.systemUsage.memoryUsage=128 mb
# disk space memory usage
activemq.broker.systemUsage.storeUsage=1 gb
# temp disk space memory usage
activemq.broker.systemUsage.tempUsage=128 mb

• 同目录下增加broker.xml，内容如下：

 

 
    
    
        
        
        
        
        
            embedded-broker.properties
        
        
 
    
 
    
 
        
        
            
        
 
        
 
        
        
 
            
 
            
        
 
 
        
        
            
                
                    
                
                
                    
                
                
                    
                
            
        
 
        
        
            
        
        
            
        
 
        
        
            
        
 
    
 
    
 
    
    
    
    
    
    
    
    
    
    
 
    
    
 

• 重启
• 同上新建第二个节点，不同之处是tomcat/webapps下不需要再部署activeMQ-broker-plugin.zip，cluster配置文件的embedded-broker.properties中的activemq.transportConnectors.server.uri=nio://127.0.0.1:61616......的端口要不同于已存在的节点设置的端口，即如果已经有了61616就应该设置其他不用于61616的端口
• 重启，geoserver界面配置
  

配置nginx

# geoserver 集群端口
upstream geoserverCluster {
    ip_hash;    # 支持session
    server localhost:8083;
    server localhost:8084;
    server localhost:8085;
}

server {
	listen       80;
    server_name  localhost;

	 # 用于访问geoserver
    location ^~ /geoserver/ {
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header Host $host:$server_port;
        proxy_pass http://geoserverCluster/geoserver/;
    }
}

nginx -t检查nginx配置脚本是否有错
nginx -s reload 重新加载脚本
