Linux Enterprise Common Service---haproxy+nginx build a Web high-availability cluster

Prepare before deployment:

Iptables and SELinux are not configured, turn off

Mount system image as local Yum source, modify Yum file

Source Package Preparation nginx.1.6.0.tar.gz haproxy-1.4.24.tar.gz

Experimental Environment Description:

Two nginx 192.168.100.110 and192.168.100.120 respectively

a haproxy to 192.168.100.160

1, respectively, on the three and three to build nginx

Yum-y install pcre-devel Zlib-devel # #安装依赖包

Useradd-m-s/sbin/nologon Nginx

Tar zxvf nginx-1.6.0.tar.gz-c/usr/src/# #解压并释放

cd/usr/src/nginx-1.6.0/

./configure--prefix=/usr/local/nginx--user=nginx--group=nginx &&make &&make Install # #编译安装nginx

cd/usr/local/nginx/html/

echo "Server 192.168.100.110" >test.html # #创建测试页面

/usr/local/nginx/sbin/nginx # #启动nginx

NETSTAT-UTPLN |grep Nginx

Attention

120 and 110 are set up just like the test page is different

echo "Server 192.168.100.120" >test.html

Access Test http://192.168.100.110/test.html, http://192.168.100.120/test.html

2, compile and install Haproxy 160 do

Yum-y Install Pcre-devel Bzip2-devel

Tar zxvf haproxy-1.4.24.tar.gz-c/usr/src

Cd/usr/src/haproxy

Make Target=generic # #安装时需要注意
