?前提準備：

1. 兩臺nginx，一臺haproxy
2. nginx1：192.168.180.120
3. nginx2：192.168.180.130，NFS
4. haproxy：192.168.180.110

nginx（兩臺nginx的操作是一樣的）：

1. 安裝nginx

#先安裝這個
yum install -y epel-release
yum install -y nginx

2. 分別編寫網頁

echo "server1 192.168.180.120" >/usr/share/nginx/html/index.html
echo "server2 192.168.180.130" >/usr/share/nginx/html/index.html

3. 開啟nginx

systemctl start nginx

4. 關閉防火墻

systemctl stop firewalld
setenforce 0

---

haproxy：

1. 安裝haproxy（通過源碼包安裝）

yum install -y gcc gcc-c++ make lrzsz
tar zxf haproxy-2.9.9.tar.gz
cd haproxy-2.9.9
make TARGET=linux-glibc && make install

2. 移動主配置文件

mkdir /etc/haproxy
cp addons/ot/test/sa/haproxy.cfg /etc/haproxy/

3.?修改主配置文件

vim /etc/haproxy/haproxy.cfg
#將端口改為8080#注釋#添加內容
frontend http_frontbind *:80default_backend servers-backendbackend servers-backendmode httpserver inst1 192.168.180.120:80 check inter 80 fall 3server inst2 192.168.180.130:80 check inter 80 fall 3 backup

4. 創建自啟動腳本

cp ~/haproxy-2.9.9/examples/haproxy.init /etc/init.d/haproxy
ln -s /usr/local/sbin/haproxy /usr/sbin/haproxy
chmod +x /etc/init.d/haproxy
chkconfig --add /etc/init.d/haproxy
/etc/init.d/haproxy start

5. 關閉防火墻

systemctl stop firewalld
setenforce 0

NFS-192.168.180.130：

1. 在nginx上均安裝

yum install -y nfs-utils rpcbind

2. 創建共享目錄

mkdir -p /opt/wwwroot
vim /etc/exports
/opt/wwwroot    192.168.180.0/24(rw,sync,no_root_squash)

3. 分別啟動

systemctl start nfs
systemctl start rpcbind

4. 查看NFS共享了什么目錄

showmount -e 192.168.180.130

5. nginx均掛載NFS共享目錄

mount 192.168.180.130:/opt/wwwroot /usr/share/nginx/html/

6. 創建測試頁面

echo "nginx-NFS" > /usr/share/nginx/html/index.html

7. 訪問測試
