nginx+glassfish+keepalived (待續)

 系統環境：

centos5.4 X86_64

zh002 192.168.1.12

zh003 192.168.1.13

軟件環境：

glassfish-3.1.2-web-unix-ml.sh

nginx-1.2.0._linux.tar.gz

jdk-6u32-linux-x64-rpm.bin

 

1.安裝nginx

# useradd nginx -s /sbin/nologin 

# tar xf nginx-1.2.0._linux.tar.gz

# cd nginx-1.2.0

註釋掉 nginx-1.2.0/auto/cc/gcc裏的如下兩行，編譯出來的nginx會比較小

# debug

#CFLAGS="$CFLAGS -g"

 

#vim src/core/nginx.h

#define NGINX_VERSION "1.0.2」

#define NGINX_VER "nginx" (修改此行,去掉後面的「NGINX_VERSION」,爲了安全,這樣編譯後外界沒法獲取程序的版本號)

 

#  yum -y install pcre-devel gcc gcc-c++ openssl-devel zlib-devel make

# mkdir -p /var/cache/nginx/client_temp

# nginx -t

nginx: the configuration file /etc/nginx/nginx.conf syntax is ok

nginx: configuration file /etc/nginx/nginx.conf test is successful

 

 

2. 安裝jdk 

# chmod +x jdk-6u32-linux-x64-rpm.bin

# ./jdk-6u32-linux-x64-rpm.bin

 

# vim /etc/profile

添加三行

export JAVA_HOME=/usr/java/jdk1.6.0_27/

export CLASSPATH=$JAVA_HOME/lib:$JAVA_HOME/jre/lib

export PATH=.:$PATH:$JAVA_HOME/bin:/usr/local/glassfish3/glassfish/bin/   

# source /etc/profile

 

# java -version

java version "1.6.0_32"

Java(TM) SE Runtime Environment (build 1.6.0_32-b05)

Java HotSpot(TM) 64-Bit Server VM (build 20.7-b02, mixed mode)

 

 

3. 安裝glassfish（須要圖形界面，先配置vnc）

# rpm -q vnc-server

vnc-server-4.1.2-14.el5_3.1

# vncserver

設置密碼

# vncserver -kill :1

# vim ~/.vnc/xstartup

 

去掉這兩行前的# 註釋

unset SESSION_MANAGER

exec /etc/X11/xinit/xinitrc

 

# vncserver

 

# ./glassfish-3.1.2-web-unix-ml.sh

 

安裝過程共出現http Port: Host name not foud 須要在hosts裏添加一條記錄

127.0.0.1 zh002 （另一臺機子也是同樣，改爲zh003便可）

 

裝完以後修改/etc/profile裏的

export PATH=$PATH:$JAVA_HOME/bin:/usr/local/glassfish3/glassfish/bin/   

 

# source /etc/profile

 

裝完後默認的管理端口是4848，web端口是8080

啓動服務

# asadmin start-domain domain1

關閉服務：

# asadmin stop-domain domain1

若是須要遠程web訪問的話，須要打開Server(Admin Server)-General-Secure Administration-Enable Secure Admin (啓用遠程管理必須是要密碼

 

的)

設置密碼：Domain-Administrator Password

 

 

能夠遠程訪問管理了

http://192.168.1.12:4848/

http://192.168.1.13:4848/

 

 

4. 配置keepalived 來實現機器的集羣功能

 

# wget http://www.keepalived.org/software/keepalived-1.2.2.tar.gz

# yum -y install gcc gcc-c++ openssl-devel

# tar xf keepalived-1.2.2.tar.gz

# cd keepalived-1.2.2

# ./configure --prefix=/usr/local/keepalived

# make && make install

# cp /usr/local/keepalived/sbin/keepalived /usr/sbin/

# cp /usr/local/keepalived/etc/sysconfig/keepalived /etc/sysconfig/

# cp /usr/local/keepalived/etc/rc.d/init.d/keepalived /etc/init.d/

# mkdir /etc/keepalived

 

192.168.1.12

Keepalived配置：

# cat /etc/keepalived/keepalived.conf

! Configuration File for keepalived

# written by :Dennis

global_defs {

router_id Nginx_Id_2

}

vrrp_script chk_nginx {

script "/opt/check_http.sh"

interval 2

weight 2

}

vrrp_instance Nginx1 {

state BACKUP

interface eth0

virtual_router_id 51

priority 110

authentication {

auth_type PASS

auth_pass 1111

}

track_script { #檢查腳本

        chk_nginx

        }

virtual_ipaddress {

192.168.1.14

}

}

 

 

# cat /opt/check_http.sh

#!/bin/bash

url="http://192.168.1.12/index.html"

status=$(/usr/bin/curl -s --head "$url" | awk '/HTTP/ {print $2}')

if [ "$status" != "200" ]; then

/etc/init.d/keepalived stop

fi

 

# chmod +x /opt/check_http.sh

 

啓動服務及設置開機自啓動：

# nginx

# /etc/init.d/keepalived start

# echo "/usr/sbin/nginx" >> /etc/rc.local

# chkconfig keepalived on

 

192.168.1.13

Keepalived配置：

! Configuration File for keepalived

# written by :Dennis

global_defs {

        router_id Nginx_Id_1

        }

vrrp_script chk_nginx {

        script "/opt/check_http.sh" #定義檢測腳本

        interval 2 #檢測間隔

        weight 2

}

vrrp_instance Nginx1 { #定義一個實例

        state MASTER #定義爲master

        interface eth0

        virtual_router_id 51 # 0-255 在同一個instance 中一致在整個vrrp 中惟一

        priority 150 #優先級，優先級最大的會成爲master

        authentication {

        auth_type PASS

        auth_pass 1111

}

track_script { #檢查腳本

        chk_nginx

        }

virtual_ipaddress { #此實例的浮動IP

        192.168.1.14

        }

}

 

# cat /opt/check_http.sh

url="http://192.168.1.13/index.html"

status=$(/usr/bin/curl -s --head "$url" | awk '/HTTP/ {print $2}')

if [ "$status" != "200" ]; then

/etc/init.d/keepalived stop

fi

 

# chmod +x /opt/check_http.sh
