一.试验环境概述
1>.操作平台介绍
[[email protected] ~]# uname -r 3.10.0-957.el7.x86_64 [[email protected] ~]# [[email protected] ~]# uname -m x86_64 [[email protected] ~]# [[email protected] ~]# cat /etc/redhat-release CentOS Linux release 7.6.1810 (Core) [[email protected] ~]# [[email protected] ~]# free -h total used free shared buff/cache available Mem: 7.6G 126M 7.4G 8.6M 129M 7.3G Swap: 7.9G 0B 7.9G [[email protected] ~]# [[email protected] ~]# cat /etc/hosts 127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4 ::1 localhost localhost.localdomain localhost6 localhost6.localdomain6 172.30.1.101 node101.yinzhengjie.org.cn node101.yinzhengjie.com 172.30.1.102 node102.yinzhengjie.org.cn 172.30.1.103 node103.yinzhengjie.org.cn 172.30.1.104 node104.yinzhengjie.org.cn 172.30.1.105 node105.yinzhengjie.org.cn 172.30.1.106 node106.yinzhengjie.org.cn 172.30.1.107 node107.yinzhengjie.org.cn 172.30.1.108 node108.yinzhengjie.org.cn [[email protected] ~]# [[email protected] ~]#
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
[[email protected] ~]# yum -y install epel-release
2>.安装nginx和php
[[email protected] ~]# 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
[[email protected] ~]# vim /etc/nginx/nginx.conf [[email protected] ~]# [[email protected] ~]# 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 { } } } [[email protected] ~]# [[email protected] ~]# 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 [[email protected] ~]#
4>.启动nginx和php服务
[[email protected] ~]# ss -ntl State Recv-Q Send-Q Local Address:Port Peer Address:Port LISTEN 0 128 *:22 *:* LISTEN 0 128 :::22 :::* [[email protected] ~]# [[email protected] ~]# systemctl start nginx php-fpm [[email protected] ~]# [[email protected] ~]# ss -ntl State Recv-Q Send-Q Local Address:Port Peer Address:Port LISTEN 0 128 127.0.0.1:9000 *:* LISTEN 0 128 *:80 *:* LISTEN 0 128 *:22 *:* LISTEN 0 128 :::80 :::* LISTEN 0 128 :::22 :::* [[email protected] ~]# [[email protected] ~]#
5>.创建php的测试页面,并通过浏览器访问"http://node104.yinzhengjie.org.cn/index.php"
[[email protected] ~]# vim /usr/share/nginx/html/index.php [[email protected] ~]# [[email protected] ~]# cat /usr/share/nginx/html/index.php php phpinfo(); ?> [[email protected] ~]# [[email protected] ~]#
三.部署Apache httpd服务器处理静态页面
1>.安装apache httpd服务器
[[email protected] ~]# yum -y install httpd
2>.创建测试数据
[[email protected] ~]# rz #随便上传一张测试图片即可 [[email protected] ~]# [[email protected] ~]# ll total 120 -rw-r--r-- 1 root root 122026 Dec 16 19:58 02.迪丽热巴.jfif [[email protected] ~]# [[email protected] ~]# file 02.迪丽热巴.jfif 02.迪丽热巴.jfif: JPEG image data, JFIF standard 1.01 [[email protected] ~]# [[email protected] ~]# mkdir -pv /var/www/html/images mkdir: created directory ‘/var/www/html/images’ [[email protected] ~]# [[email protected] ~]# mv 02.迪丽热巴.jfif /var/www/html/images/01.jpeg [[email protected] ~]# [[email protected] ~]# ll -R /var/www/html/ /var/www/html/: total 0 drwxr-xr-x 2 root root 21 Jan 5 20:15 images /var/www/html/images: total 120 -rw-r--r-- 1 root root 122026 Dec 16 19:58 01.jpeg [[email protected] ~]#
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)
[[email protected] ~]# ss -ntl State Recv-Q Send-Q Local Address:Port Peer Address:Port LISTEN 0 128 *:22 *:* LISTEN 0 128 :::22 :::* [[email protected] ~]# [[email protected] ~]# systemctl start httpd [[email protected] ~]# [[email protected] ~]# ss -ntl State Recv-Q Send-Q Local Address:Port Peer Address:Port LISTEN 0 128 *:80 *:* LISTEN 0 128 *:22 *:* LISTEN 0 128 :::22 :::* [[email protected] ~]# [[email protected] ~]#
四.配置haproxy基于访问路径匹配案例
1>.编辑haproxy的配置文件
[[email protected] ~]# cat /etc/haproxy/haproxy.cfg global maxconn 100000 chroot /yinzhengjie/softwares/haproxy stats socket /yinzhengjie/softwares/haproxy/haproxy.sock mode 600 level admin user haproxy group haproxy daemon nbproc 2 cpu-map 1 0 cpu-map 2 1 nbthread 2 pidfile /yinzhengjie/softwares/haproxy/haproxy.pid log 127.0.0.1 local5 info defaults option http-keep-alive option forwardfor option redispatch option abortonclose maxconn 100000 mode http timeout connect 300000ms timeout client 300000ms timeout server 300000ms errorloc 503 http://node107.yinzhengjie.org.cn/monitor/503.html listen status_page bind 172.30.1.102:8888 stats enable stats uri /haproxy-status stats auth admin:yinzhengjie stats realm "Welcome to the haproxy load balancer status page of YinZhengjie" stats hide-version stats admin if TRUE stats refresh 5s frontend WEB_PORT_80 bind 172.30.1.102:80 mode http #定义ACL匹配所有以".php"结尾的文件的php程序 acl php_server path_end -i .php #将php的请求交给nginx服务器去处理. use_backend nginx_php if php_server #定义ACL匹配所有访问路径 acl static_path path_beg -i /static /images /javascript #将图片的请求交给httpd服务器去处理. use_backend apache_httpd if static_path default_backend backup_web backend nginx_php server web04 172.30.1.104:80 check inter 3000 fall 3 rise 5 backend apache_httpd server web03 172.30.1.103:80 check inter 3000 fall 3 rise 5 backend backup_web server web03 172.30.1.108:80 check inter 3000 fall 3 rise 5 [[email protected] ~]# [[email protected] ~]# systemctl restart haproxy #别忘记重启haproxy使得配置文件生效哟~ [[email protected] ~]# [[email protected] ~]#
2>.查看haproxy的监听端口和进程信息
[[email protected] ~]# 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 :::* [[email protected] ~]# [[email protected] ~]# 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 [[email protected] ~]# [[email protected] ~]#
3>.查看haproxy的状态页(http://node102.yinzhengjie.org.cn:8888/haproxy-status)
五.验证haproxy的配置
