haproxy+keepalived搭建web羣集

1、實驗環境

2、實驗步驟

haproxy+keepalived 1配置

IP：192.168.1.10

#yum   -y  install pcre-devel  zlib-devel bzip2-devel kernel-devel  openssl-devel popt-devel  zlib-devel

#tar zxf  keepalived-1.2.13.tar.gz         解壓源碼包

#cd keepalived-1.2.13

#./configure --prefix=/    --with-kernel-dir=/usr/src/kernels/2.6.32-431.e16.x86_64

#make  && make install

#chkconfig  --add keepalived             添加爲系統服務

#chkconfig  keepalived  on           設置爲開機自啓動

#cd /etc/keeplived/

#cp  keepalived.conf     keepalived.conf.bak 備份一份以防萬一

#vim keepalived.conf                編輯主配置文件

#service keepalived   start      啓動keepalved服務  

#ip addr  show  eth0            查看漂移地址

配置haproxy  1

#tar  zxf  haproxy-1.4.24.tar.gz

#cd  haproxy-1.4.24

#make TARGET=linux26                    64位系統

#make install

#mkdir  /etc/haproxy                   建立配置文件目錄

#cp  examples/haproxy.cfg   /etc/haproxy/   將haproxy.cfg文件複製到配置文件目錄

#vim  /etc/haproxy/haproxy.cfg

#cp /usr/src/haproxy-1.4.24/examples/haproxy.init  /etc/init.d/haproxy

#ln   -s  /usr/local/sbin/haproxy  /usr/sbin/haproxy

#chmod   +x  /etc/init.d/haproxy

#service haproxy   start

#service  iptables  stop

haproxy+keepalived  2配置

IP：192.168.1.20

#yum   -y  install pcre-devel  zlib-devel bzip2-devel kernel-devel  openssl-devel popt-devel  zlib-devel

#tar zxf  keepalived-1.2.13.tar.gz

#cd keepalived-1.2.13

#./configure  --prefix=/    --with-kernel-dir=/usr/src/kernels/2.6.32-431.e16.x86_64

#make  && make install

#chkconfig  --add keepalived

#chkconfig  keepalived  on

#scp  root@192.168.1.10:/etc/keepalived/keepalived.conf  /etc/keepalived/

#scp root@192.168.1.10:/etc/keepalived/keepalived.conf.bak      /etc/keepalived/          遠程複製一份主的配置

#vim /etc/keepalived/keepalived.conf    作簡單修改便可

#service keepalived   restart

#ip  addr  show   dev  eth0

配置haproxy  2

#tar  zxf  haproxy-1.4.24.tar.gz        使用源碼編譯安裝

#cd  haproxy-1.4.24

#make TARGET=linux26                     64位系統

#make install

#mkdir  /etc/haproxy                   建立配置文件目錄

#cp  examples/haproxy.cfg   /etc/haproxy/   將haproxy.cfg文件複製到配置文件目錄

#scp root@192.168.1.10:/etc/haproxy/haproxy.cfg  /etc/haproxy/haproxy/

從主複製到從一份此處不用修改

#cp /usr/src/haproxy-1.4.24/examples/haproxy.init  /etc/init.d/haproxy

#ln   -s  /usr/local/sbin/haproxy  /usr/sbin/haproxy

#chmod   +x  /etc/init.d/haproxy      給一個執行權限

#service  haproxy  start    

#service  iptables  stop
