下文给大家带来Centos 7部署Nginx网站服务、内网客户端、Haproxy云服务器等详情，希望能够给大家在实际运用中带来一定的帮助，负载均衡涉及的东西比较多，理论也不多，网上有很多书籍，今天我们就用在行业内累计的经验来做一个解答。

一、部署第一台Nginx网站

关于Nginx的原理概述及详细配置请参考博文：Centos 7部署Nginx网站服务

[root@centos01 ~]# yum -y install prce-devel zlib-devel [root@centos01 ~]# useradd -M -s /sbin/nologin nginx  [root@centos01 ~]# umount /mnt/      mount: /dev/sr0 写保护，将以只读方式挂载[root@centos01 ~]# scp /mnt/nginx-1.6.0.tar.gz root@192.168.100.20:/root           The authenticity of host '192.168.100.20 (192.168.100.20)' can't be established.ECDSA key fingerprint is SHA256:PUueT9fU9QbsyNB5NC5hbSXzaWxxQavBxXmfoknXl4I.ECDSA key fingerprint is MD5:6d:f7:95:0e:51:1a:d8:9e:7b:b6:3f:58:51:51:4b:3b.Are you sure you want to continue connecting (yes/no)? yes   Warning: Permanently added '192.168.100.20' (ECDSA) to the list of known hosts.root@192.168.100.20's password: nginx-1.6.0.tar.gz                                      100%  784KB  68.2MB/s   00:00[root@centos01 ~]# scp /mnt/haproxy-1.4.24.tar.gz root@192.168.100.30:/root             The authenticity of host '192.168.100.30 (192.168.100.30)' can't be established.ECDSA key fingerprint is SHA256:PUueT9fU9QbsyNB5NC5hbSXzaWxxQavBxXmfoknXl4I.ECDSA key fingerprint is MD5:6d:f7:95:0e:51:1a:d8:9e:7b:b6:3f:58:51:51:4b:3b.Are you sure you want to continue connecting (yes/no)? yes   Warning: Permanently added '192.168.100.30' (ECDSA) to the list of known hosts.root@192.168.100.30's password: haproxy-1.4.24.tar.gz                                                                               100%  817KB  31.1MB/s   00:00  00:00  [root@centos01 ~]# tar zxvf /mnt/nginx-1.6.0.tar.gz -C /usr/src/   [root@centos01 ~]# cd /usr/src/nginx-1.6.0/    [root@centos01 nginx-1.6.0]# ./configure --prefix=/usr/local/nginx --user=nginx         [root@centos01 nginx-1.6.0]# make && make install  [root@centos01 ~]# ln -s /usr/local/nginx/sbin/* /usr/local/sbin/  [root@centos01 ~]# echo "192.168.100.10:nginx" > /usr/local/nginx/html/index.html       [root@centos01 ~]# nginx  [root@centos01 ~]# netstat -anptu | grep nginx tcp        0      0 0.0.0.0:80              0.0.0.0:*               LISTEN      3685/ngin: master

二、部署第二台Nginx网站

[root@centos02 ~]# yum -y install pcre-devel zlib-devel  [root@centos02 ~]# lsanaconda-ks.cfg  initial-setup-ks.cfg  nginx-1.6.0.tar.gz[root@centos02 ~]# tar zxvf nginx-1.6.0.tar.gz -C /usr/src/   [root@centos02 ~]# useradd -M -s /sbin/nologin nginx   [root@centos02 ~]# cd /usr/src/nginx-1.6.0/ [root@centos02 nginx-1.6.0]# ./configure --prefix=/usr/local/nginx --user=nginx            [root@centos02 nginx-1.6.0]# make && make install [root@centos02 ~]# ln -s /usr/local/nginx/sbin/* /usr/local/sbin/ [root@centos02 ~]# echo "192.168.100.20:nginx" > /usr/local/nginx/html/index.html           [root@centos02 ~]# nginx [root@centos02 ~]# netstat -anptu | grep nginxtcp        0      0 0.0.0.0:80              0.0.0.0:*               LISTEN      6059/ngin: master

三、部署内网客户端

1、客户端添加VM1网卡，配置和服务器同网段IP地址

2、访问第一台nginx服务器

3、客户端更换IP地址访问第二台nginx服务器

四、部署Haproxy服务器

Haproxy概述及工作原理详细配置参考博文：Haproxy搭建Web群集概述
Centos 7基于Haproxy搭建高可用Web群集

1、安装haproxy

[root@centos03 ~]# yum -y install pcre-devel bzip2-devel  [root@centos03 ~]# lsanaconda-ks.cfg  haproxy-1.4.24.tar.gz  initial-setup-ks.cfg[root@centos03 ~]# tar zxvf haproxy-1.4.24.tar.gz -C /usr/src/  [root@centos03 ~]# cd /usr/src/haproxy-1.4.24/  [root@centos03 haproxy-1.4.24]# make TARGET=linux26 [root@centos03 haproxy-1.4.24]# make install

2、生成haproxy配置文件

[root@centos03 ~]# mkdir /etc/haproxy  [root@centos03 ~]# cp /usr/src/haproxy-1.4.24/examples/haproxy.cfg /etc/haproxy/                 [root@centos03 ~]# cp /usr/src/haproxy-1.4.24/examples/haproxy.init /etc/init.d/haproxy          [root@centos03 ~]# chmod +x /etc/init.d/haproxy [root@centos03 ~]# chkconfig --add haproxy  [root@centos03 ~]# chkconfig --level 35 haproxy on [root@centos03 ~]# cp /usr/src/haproxy-1.4.24/haproxy /usr/sbin/ [root@centos03 ~]# mkdir -p /usr/share/haproxy

3、配置haproxy群集

[root@centos03 ~]# vim /etc/haproxy/haproxy.cfg   listen  nginx 192.168.100.30:80           balance roundrobin        server  web01 192.168.100.10:80 check inter 2000 fall 3           server  web02 192.168.100.20:80 check inter 2000 fall 3  [root@centos03 ~]# /etc/init.d/haproxy start  Starting haproxy (via systemctl):                          [  确定  ]

1）客户端访问192.168.100.30

2）客户端更换IP地址重新访问

五、配置Firewalld防火墙（双网卡）

关于Firewalld防火墙的概述及详细配置请参考博文：Centos 7的Firewalld防火墙基础
Centos 7的firewalld防火墙地址伪装和端口转发原理
centos 7之firewalld防火墙配置IP伪装和端口转发案例详解

[root@centos04 ~]# cp /etc/sysconfig/network-scripts/ifcfg-ens32 /etc/sysconfig/network-scripts/ifcfg-ens34   [root@centos04 ~]# vim /etc/sysconfig/network-scripts/ifcfg-ens34                   TYPE=EthernetPROXY_METHOD=noneBROWSER_ONLY=noBOOTPROTO=staticDEFROUTE=yesNAME=ens34DEVICE=ens34ONBOOT=yesIPADDR=192.168.200.254  NATEMASK=255.255.255.0DNS1=192.168.200.254   [root@centos04 ~]# systemctl restart network   [root@centos04 ~]# vim /etc/sysctl.conf   net.ipv4.ip_forward = 1[root@centos04 ~]# sysctl -p  [root@centos01 ~]# vim /etc/sysconfig/network-scripts/ifcfg-ens32                   GATEWAY=192.168.100.40       [root@centos01 ~]# systemctl restart network  [root@centos04 ~]# systemctl start firewalld.service   [root@centos04 ~]# systemctl enable firewalld.service  [root@centos04 ~]# firewall-cmd --add-interface=ens34 --zone=external           The interface is under control of NetworkManager, setting zone to 'external'.success[root@centos04 ~]# firewall-cmd --add-interface=ens32 --zone=trusted              The interface is under control of NetworkManager, setting zone to 'trusted'.success[root@centos04 ~]# firewall-cmd --get-active-zones   external  interfaces: ens34trusted  interfaces: ens32[root@centos04 ~]# firewall-cmd --remove-masquerade --zone=external              success[root@centos04 ~]# firewall-cmd --add-rich-rule='rule family=ipv4 source address=192.168.100.0/24 masquerade' success[root@centos04 ~]# firewall-cmd --add-rich-rule='rule family=ipv4 destination address=192.168.200.254/32 forward-port port=80 protocol=tcp to-addr=192.168.100.30'success[root@centos04 ~]# firewall-cmd --zone=external --add-service=http            success[root@centos04 ~]# firewall-cmd --zone=external --add-service=dns           success[root@centos04 ~]# firewall-cmd --zone=external --list-allexternal (active)  target: default  icmp-block-inversion: no  interfaces: ens34  sources:   services: ssh http dns  ports:   protocols:   masquerade: no  forward-ports:   source-ports:   icmp-blocks:   rich rules:     rule family="ipv4" source address="192.168.100.0/24" masquerade    rule family="ipv4" destination address="192.168.200.254/32" forward-port port="80" protocol="tcp" to-addr="192.168.100.30"

六、部署DNS

关于DNS详细配置及概述请参考博文：CentOS7简单搭建DNS服务

[root@centos04 ~]# yum -y install bind bind-chroot bind-utils [root@centos04 ~]# echo "" > /etc/named.conf   [root@centos04 ~]# vim /etc/named.conf   options {        listen-on       port    53      { any; };        directory       "/var/named";};zone    benet.com        IN      {        type    master;        file    "benet.com.zone";};[root@centos04 ~]# named-checkconf -z /etc/named.conf          [root@centos04 ~]# vim /var/named/benet.com.zone           $TTL    86400@       SOA     benet.com.       root.benet.com.(        2020021801        1H        15M        1W        1D)@       NS      centos04.benet.com.centos04 A      192.168.200.254www      A      192.168.200.254[root@centos04 ~]# named-checkzone benet.com /var/named/benet.com.zone            zone benet.com/IN: loaded serial 2020021801OK[root@centos04 ~]# chmod +x /var/named/benet.com.zone           [root@centos04 ~]# chown named:named /var/named/benet.com.zone[root@centos04 ~]# systemctl start named  [root@centos04 ~]# systemctl enable named
