2>.试验架构说明
node102.yinzhengjie.org.cn:
haproxy服务器
node103.yinzhengjie.org.cn:
Apache httpd模拟静态数据,如存放的图片,html,css,javascript等。
node104.yinzhengjie.org.cn:
"Nginx + php环境"模拟动态数据,php程序等。
二.部署Nginx服务器处理动态页面
1>.安装epel源
[root@node104.yinzhengjie.org.cn ~]# yum -y install epel-release
2>.安装nginx和php
[root@node104.yinzhengjie.org.cn ~]# yum -y install nginx php-fpm
3>.修改nginx的配置文件,添加一个匹配php文件的localtion
[root@node104.yinzhengjie.org.cn ~]# vim /etc/nginx/nginx.conf
[root@node104.yinzhengjie.org.cn ~]#
[root@node104.yinzhengjie.org.cn ~]# egrep -v "^ *#|^$" /etc/nginx/nginx.conf
user nginx;
worker_processes auto;
error_log /var/log/nginx/error.log;
pid /run/nginx.pid;
include /usr/share/nginx/modules/*.conf;
events {
worker_connections 1024;
}
http {
log_format main '$remote_addr - $remote_user [$time_local] "$request" '
'$status $body_bytes_sent "$http_referer" '
'"$http_user_agent" "$http_x_forwarded_for"';
access_log /var/log/nginx/access.log main;
sendfile on;
tcp_nopush on;
tcp_nodelay on;
keepalive_timeout 65;
types_hash_max_size 2048;
include /etc/nginx/mime.types;
default_type application/octet-stream;
include /etc/nginx/conf.d/*.conf;
server {
listen 80 default_server;
listen [::]:80 default_server;
server_name _;
root /usr/share/nginx/html;
include /etc/nginx/default.d/*.conf;
location / {
}
location ~ \.php$ {
root html;
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
include fastcgi_params;
}
error_page 404 /404.html;
location = /40x.html {
}
error_page 500 502 503 504 /50x.html;
location = /50x.html {
}
}
}
[root@node104.yinzhengjie.org.cn ~]#
[root@node104.yinzhengjie.org.cn ~]# nginx -t #检查nginx的配置文件是否正确
nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: configuration file /etc/nginx/nginx.conf test is successful
[root@node104.yinzhengjie.org.cn ~]#
4>.启动nginx和php服务
[root@node104.yinzhengjie.org.cn ~]# ss -ntl
State Recv-Q Send-Q Local Address:Port Peer Address:Port
LISTEN 0 128 *:22 *:*
LISTEN 0 128 :::22 :::*
[root@node104.yinzhengjie.org.cn ~]#
[root@node104.yinzhengjie.org.cn ~]# systemctl start nginx php-fpm
[root@node104.yinzhengjie.org.cn ~]#
[root@node104.yinzhengjie.org.cn ~]# ss -ntl
State Recv-Q Send-Q Local Address:Port Peer Address:Port
LISTEN 0 128 127.0.0.1:9000 *:*

LISTEN 0 128 :::22 :::*
[root@node104.yinzhengjie.org.cn ~]#
[root@node104.yinzhengjie.org.cn ~]#
5>.创建php的测试页面,并通过浏览器访问"http://node104.yinzhengjie.org.cn/index.php"
[root@node104.yinzhengjie.org.cn ~]# vim /usr/share/nginx/html/index.php
[root@node104.yinzhengjie.org.cn ~]#
[root@node104.yinzhengjie.org.cn ~]# cat /usr/share/nginx/html/index.php
<?php
phpinfo();
?>
[root@node104.yinzhengjie.org.cn ~]#
[root@node104.yinzhengjie.org.cn ~]#
三.部署Apache httpd服务器处理静态页面
1>.安装apache httpd服务器
[root@node103.yinzhengjie.org.cn ~]# yum -y install httpd
2>.创建测试数据
[root@node103.yinzhengjie.org.cn ~]# rz #随便上传一张测试图片即可
[root@node103.yinzhengjie.org.cn ~]#
[root@node103.yinzhengjie.org.cn ~]# ll
total 120
-rw-r--r-- 1 root root 122026 Dec 16 19:58 02.迪丽热巴.jfif
[root@node103.yinzhengjie.org.cn ~]#
[root@node103.yinzhengjie.org.cn ~]# file 02.迪丽热巴.jfif
02.迪丽热巴.jfif: JPEG image data, JFIF standard 1.01
[root@node103.yinzhengjie.org.cn ~]#
[root@node103.yinzhengjie.org.cn ~]# mkdir -pv /var/www/html/images
mkdir: created directory ‘/var/www/html/images’
[root@node103.yinzhengjie.org.cn ~]#
[root@node103.yinzhengjie.org.cn ~]# mv 02.迪丽热巴.jfif /var/www/html/images/01.jpeg
[root@node103.yinzhengjie.org.cn ~]#
[root@node103.yinzhengjie.org.cn ~]# ll -R /var/www/html/
/var/www/html/:

-rw-r--r-- 1 root root 122026 Dec 16 19:58 01.jpeg
[root@node103.yinzhengjie.org.cn ~]#
3>.启动httpd服务并使用浏览器访问上一步创建的图片(http://node103.yinzhengjie.org.cn/images/01.jpeg)
[root@node103.yinzhengjie.org.cn ~]# ss -ntl
State Recv-Q Send-Q Local Address:Port Peer Address:Port
LISTEN 0 128 *:22 *:*
LISTEN 0 128 :::22 :::*
[root@node103.yinzhengjie.org.cn ~]#
[root@node103.yinzhengjie.org.cn ~]# systemctl start httpd
[root@node103.yinzhengjie.org.cn ~]#
[root@node103.yinzhengjie.org.cn ~]# ss -ntl
State Recv-Q Send-Q Local Address:Port Peer Address:Port

LISTEN 0 128 :::22 :::*
[root@node103.yinzhengjie.org.cn ~]#
[root@node103.yinzhengjie.org.cn ~]#
四.配置haproxy基于访问路径匹配案例
1>.编辑haproxy的配置文件
[root@node102.yinzhengjie.org.cn ~]# cat /etc/haproxy/haproxy.cfg
global
maxconn 100000
chroot /yinzhengjie/softwares/haproxy
stats socket /yinzhengjie/softwares/haproxy/haproxy.sock mode 600 level admin

[root@node102.yinzhengjie.org.cn ~]#
[root@node102.yinzhengjie.org.cn ~]# systemctl restart haproxy #别忘记重启haproxy使得配置文件生效哟~
[root@node102.yinzhengjie.org.cn ~]#
[root@node102.yinzhengjie.org.cn ~]#
2>.查看haproxy的监听端口和进程信息
[root@node102.yinzhengjie.org.cn ~]# ss -ntl
State Recv-Q Send-Q Local Address:Port Peer Address:Port
LISTEN 0 128 172.30.1.102:80 *:*
LISTEN 0 128 *:22 *:*
LISTEN 0 128 172.30.1.102:8888 *:*
LISTEN 0 128 :::22 :::*
[root@node102.yinzhengjie.org.cn ~]#
[root@node102.yinzhengjie.org.cn ~]# ps -ef | grep haproxy | grep -v grep
root 20587 1 0 20:09 ? 00:00:00 /usr/sbin/haproxy -Ws -f /etc/haproxy/haproxy.cfg -p /yinzhengjie/softwares/haproxy/haproxy.pid
haproxy 20589 20587 0 20:09 ? 00:00:00 /usr/sbin/haproxy -Ws -f /etc/haproxy/haproxy.cfg -p /yinzhengjie/softwares/haproxy/haproxy.pid
haproxy 20590 20587 0 20:09 ? 00:00:00 /usr/sbin/haproxy -Ws -f /etc/haproxy/haproxy.cfg -p /yinzhengjie/softwares/haproxy/haproxy.pid
[root@node102.yinzhengjie.org.cn ~]#
[root@node102.yinzhengjie.org.cn ~]#
3>.查看haproxy的状态页(http://node102.yinzhengjie.org.cn:8888/haproxy-status)
五.验证haproxy的配置
1>.浏览器访问haproxy的地址:"http://node102.yinzhengjie.org.cn/index.php",如下图所示
2>.浏览器访问haproxy的地址:"http://node102.yinzhengjie.org.cn/images/01.jpeg",如下图所示
