jetty在Linux下的配置

浏览数：217 / 时间：2015年06月20日

jetty官网：http://www.eclipse.org/jetty/

具体配置流程如下1, 2:

1. Nginx 添加监听域名和路由端口.

#当前应用的可用流(可无限添加)

upstream pisaTbt0 {

server 10.221.12.182:8051 weight=1;

server 10.221.12.182:8052 weight=1;

keepalive 256;

}

upstream pisaTbt1 {

server 10.221.12.182:8061 weight=1;

server 10.221.12.182:8062 weight=1;

keepalive 256;

}

#监听域名，此处可配置监听多个端口

server {

listen 80;

server_name 203.195.182.194;

location ^~ /pisa-tbt/ {

proxy_pass http://pisaTbt0;

proxy_set_header Host $host;

proxy_set_header X-Real-IP $remote_addr;

proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

}

server {

listen 8080;

server_name 203.195.182.194;

location ^~ /pisa-tbt/ {

proxy_pass http://pisaTbt1;

proxy_set_header Host $host:8080;

proxy_set_header X-Real-IP $remote_addr;

proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

}

2. 配置和启动Jetty独立服务

1) 拷贝davinciDev或WukongDev为自己的应用目录(除了配置文件和日志目录其余全部为软连接, 不用担心版本问题)

3) 进入{Jetty目录}/standalone/{自己的应用地址}

4) 修改server.conf, 指定当前服务的两个端口号, 和上方的Nginx流内的端口号对应.

5) 修改etc/jetty-http.xml中的jetty.host为要启动的host

6) 执行 server.sh start 启动服务, 启动后将自动在两个端口号内选择一个执行.

7) 如果需要热重启服务时则执行 server.sh switch 进行切换, 脚本会启动新服务并保证可用的情况下关闭老服务. Nginx则会自动路由请求到新服务.

Jetty独立服务介绍:

目录结构:

./data 存储PID和启动进度信息.

./etc 应用目录配置, 启动监听配置.(设置项会自动配置, 所以无需更改)，此目录中主要包括jetty-deploy.xml和jetty-started.xml，这两个文件会替代全局配置

./log jetty的启动日志(针对当前独立应用)

./server.conf 启动端口号配置

./server.sh 独立服务执行脚本(包括三个命令, server.sh start:启动服务, server.sh stop:关闭服务, server.sh switch:切换服务)

./webapps 应用存放位置

jetty war包解压设置

自定义的解压路径设置比较复杂，最简的就是在jetty根目录下增加一work目录，jetty就会把war包解压路径放在work下面

jetty根目录下的start.ini可以配置jvm的一些参数，简要示例如下，在末尾添加以下参数:

--exec
-Xmx1024m
-Xms1024m
-Xmn512m
-XX:PermSize=128m
-XX:MaxPermSize=128m
-XX:MaxTenuringThreshold=7
-XX:GCTimeRatio=19
-XX:+UseConcMarkSweepGC
-XX:ParallelGCThreads=8
-XX:+CMSClassUnloadingEnabled
-XX:+UseCMSCompactAtFullCollection
-XX:CMSFullGCsBeforeCompaction=5
-XX:-CMSParallelRemarkEnabled
-XX:+DisableExplicitGC
-XX:CMSInitiatingOccupancyFraction=70
-XX:SoftRefLRUPolicyMSPerMB=0

jetty根目录下的start.d下的http.ini可以配置使用start.jar启动时使用的端口，此处如果使用了第二步standalone方式的启动形式，则最好把jetty.port注掉，否则有可能会有冲突
