jetty在Linux下的配置

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
 
etc/jetty-http.xml可配置jetty总的监听端口
