Centos + nginx + JBOSS AS 7 搭建Java web application

最近做了一个Java的web app，一直想在Centos环境中搭建一个完整的web服务器，现在开始动手。

先说说环境：

操作系统： Centos 6.3

WEB服务器: nginx-1.2.5

App服务器：JBOSS AS 7.0.0

1. 配置nginx:

修改/etc/nginx/nginx.conf

http{
       ...
    #--------------------------------------
    #JBOSS AS 7
    #--------------------------------------
    server{
         listen         80 default;
         location / {
           proxy_pass http://localhost:8080;
           proxy_set_header X-Forwarded-Host $host;
           proxy_set_header X-Forwarded-Server $host;
           proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
         }
    }
}    

2. 将JBOSS AS 7 standalone 添加为Centos服务

2.1. 创建script: /etc/init.d/jbossd

#!/bin/sh
#
# JBoss standalone control script
#
# chkconfig: -
# description: JBoss AS Standalone
# processname: standalone
# pidfile: /var/run/jbossd.pid
# config: /etc/jboss-as/jboss-as.conf

# Source function library.
. /etc/init.d/functions

# Load Java configuration.
[ -r /etc/java/java.conf ] && . /etc/java/java.conf
export JAVA_HOME

# Load JBoss AS init.d configuration.
if [ -z "$JBOSS_CONF" ]; then
  JBOSS_CONF=$JBOSS_HOME/bin/standalone.conf
fi

[ -r "$JBOSS_CONF" ] && . "${JBOSS_CONF}"

# Set defaults.

if [ -z "$JBOSS_HOME" ]; then
  JBOSS_HOME=/usr/local/jboss7
fi
export JBOSS_HOME

if [ -z "$JBOSS_PIDFILE" ]; then
  JBOSS_PIDFILE=/var/run/jbossd.pid
fi
export JBOSS_PIDFILE

if [ -z "$JBOSS_CONSOLE_LOG" ]; then
  JBOSS_CONSOLE_LOG=/var/log/jboss-as/console.log
fi

if [ -z "$JBOSS_USER" ]; then
  JBOSS_USER=jboss
fi

if [ -z "$STARTUP_WAIT" ]; then
  STARTUP_WAIT=
fi

if [ -z "$SHUTDOWN_WAIT" ]; then
  SHUTDOWN_WAIT=
fi

if [ -z "$JBOSS_CONFIG" ]; then
  JBOSS_CONFIG=standalone.xml
fi

JBOSS_SCRIPT=$JBOSS_HOME/bin/standalone.sh

prog='jboss-as'
CMD_PREFIX=''

if [ ! -z "$JBOSS_USER" ]; then
  if [ -x /etc/rc.d/init.d/functions ]; then
    CMD_PREFIX="daemon --user $JBOSS_USER"
  else
    CMD_PREFIX="su - $JBOSS_USER -c"
  fi
fi

start() {
  echo -n "Starting $prog: "
  if [ -f $JBOSS_PIDFILE ]; then
    read ppid < $JBOSS_PIDFILE
    if [ `ps --pid $ppid > /dev/null | grep -c $ppid > /dev/null` -eq '' ]; then
      echo -n "$prog is already running"
      failure
      echo
      return
    else
      rm -f $JBOSS_PIDFILE
    fi
  fi
  mkdir -p $(dirname $JBOSS_CONSOLE_LOG)
  cat /dev/null > $JBOSS_CONSOLE_LOG

  mkdir -p $(dirname $JBOSS_PIDFILE)
  chown $JBOSS_USER $(dirname $JBOSS_PIDFILE) || true
  #$CMD_PREFIX JBOSS_PIDFILE=$JBOSS_PIDFILE $JBOSS_SCRIPT >& > $JBOSS_CONSOLE_LOG &
  #$CMD_PREFIX JBOSS_PIDFILE=$JBOSS_PIDFILE $JBOSS_SCRIPT &

  if [ ! -z "$JBOSS_USER" ]; then
    if [ -x /etc/rc.d/init.d/functions ]; then
      daemon -s /bin/bash --user $JBOSS_USER LAUNCH_JBOSS_IN_BACKGROUND= JBOSS_PIDFILE=$JBOSS_PIDFILE $JBOSS_SCRIPT --server-config=$JBOSS_CONFIG >& > $JBOSS_CONSOLE_LOG &
    else
      su -s /bin/bash $JBOSS_USER -c "LAUNCH_JBOSS_IN_BACKGROUND=1 JBOSS_PIDFILE=$JBOSS_PIDFILE $JBOSS_SCRIPT --server-config=$JBOSS_CONFIG" >& > $JBOSS_CONSOLE_LOG &
    fi
  fi

  count=
  launched=false

  until [ $count -gt $STARTUP_WAIT ]
  do
    grep 'JBoss AS.*started in' $JBOSS_CONSOLE_LOG > /dev/null
    if [ $? -eq  ] ; then
      launched=true
      break
    fi
    sleep
    let count=$count+;
  done

  success
  echo
  return
}

stop() {
  echo -n $"Stopping $prog: "
  count=;

  if [ -f $JBOSS_PIDFILE ]; then
    read kpid < $JBOSS_PIDFILE
    let kwait=$SHUTDOWN_WAIT

    # Try issuing SIGTERM

    kill - $kpid
    until [ `ps --pid $kpid > /dev/null | grep -c $kpid > /dev/null` -eq '' ] || [ $count -gt $kwait ]
    do
      sleep
      let count=$count+;
    done

    if [ $count -gt $kwait ]; then
      kill - $kpid
    fi
  fi
  rm -f $JBOSS_PIDFILE
  success
  echo
}

status() {
  if [ -f $JBOSS_PIDFILE ]; then
    read ppid < $JBOSS_PIDFILE
    if [ `ps --pid $ppid > /dev/null | grep -c $ppid > /dev/null` -eq '' ]; then
      echo "$prog is running (pid $ppid)"
      return
    fi
  fi
  echo "$prog is not running"
}

case "$1" in
  start)
      start
      ;;
  stop)
      stop
      ;;
  restart)
      $ stop
      $ start
      ;;
  status)
      status
      ;;
  *)
      ## If no parameters are given, print which are avaiable.
      echo "Usage: $0 {start|stop|status|restart|reload}"
      exit
      ;;
esac

保存退出，运行chkconfig添加服务(注意，jbossd需要跟上面的shell script的名字一样，这样chkconfig才能找到对应的脚本)

chkconfig --add jbossd

设置运行级别

chkconfig jbossd --level  on

在运行级别2345，均会运行jboosd服务。

至此，服务器开机的时候，就会自动打开nginx和jboss服务。
