部署四台Centos 7
| Centos 7 | IP |
| Centos 7 x1 | 192.168.52.157 |
| Centos 7 x2 | 192.168.52.153 |
| Centos 7 x3 | 192.168.52.156 |
| Centos 7 x4 | 192.168.52.151 |
1.1 部署两台nginx（x1,x2两台操作都一样）
先上传安装包（下面链接里有RZ包）
http://链接: https://pan.baidu.com/s/1znryAj3qc3QnQaKSDTU6KQ 提取码: egzp
1.2 安装工具和库
[root@localhost ~]# yum -y install gcc-c++ pcre pcre-devel zlib zlib-devel openssl openssl-devel 
1.3 下载1.18.0.tar.gz的包
[root@localhost ~]# wget -c https:"//nginx.org/download/nginx-1.18.0.tar.gz" //安装工具和库
1.4 解压1.18.0.tar.gz的包
[root@localhost ~]# tar -zxvf nginx-1.18.0.tar.gz //下载1.18.0.tar.gz的包1.5 进入nginx目录然后编辑与安装nginx
[root@localhost ~]# cd nginx- 1.18.0 //进入nginx目录
[root@localhost nginx-1.18.0]# ./configure --prefix=/usr/local/nginx --with-http_stub_status_module --with-http_ssl_module --with-http_v2_module --with-http_sub_module --with-http_gzip_static_module --with-pcre //编辑安装nginx1.6 进入到安装nginx目录下面的sbin
[root@localhost nginx-1.18.0]# make
[root@localhost nginx-1.18.0]# make install
[root@localhost nginx-1.18.0]# /usr/local/nginx/sbin/nginx //进入到安装nginx目录下面的sbin
[root@localhost nginx-1.18.0]# ./nginx //启动最后启动就行了
然后去游览器搜索ip
2.1 编译安装haproxy（Centos x3）
先上传安装包（下面链接里有RZ包）

[root@localhost ~]# yum -y install pcre-devel bzip2-devel
[root@localhost ~]# tar zxf haproxy-1.5.19.tar.gz -C /usr/src/
[root@localhost ~]# cd /usr/src/haproxy-1.5.19/
[root@localhost haproxy-1.5.19]# make TARGET=linux26 && make install2.2 haproxy服务配置
[root@localhost ~]# mkdir /etc/haproxy //创建配置文件目录
[root@localhost ~]# cd /usr/src/haproxy-1.5.19/
[root@localhost haproxy-1.5.19]# cd /etc/haproxy/2.3 进入vim编辑
把IP设置成前两个Centos 7 x1,x2的ip，保存
[root@localhost haproxy-1.5.19]# vim /haproxy.cfg
global
log /dev/log local0 info
log /dev/log local0 notice
#log loghost local0 info
maxconn 4096
#chroot /usr/share/haproxy
uid 99
gid 99
daemon
#debug
#quiet
defaults
log global
mode http
option httplog
option dontlognull
retries 3
redispatch
maxconn 2000
contimeout 5000
clitimeout 50000
srvtimeout 50000
listen webserver 0.0.0.0:80
option httpchk GET /index.html
balance roundrobin
server inst1 192.168.52.157:80 check inter 2000 fall 3
server inst2 192.168.52.153:80 check inter 2000 fall 32.4最后创建开机自启动的命令
[root@localhost ~]# cd /usr/src/haproxy-1.5.19/
[root@localhost haproxy-1.5.19]# cp examples/haproxy.init /etc/init.d/haproxy
[root@localhost haproxy-1.5.19]# ln -s /usr/local/sbin/haproxy /usr/sbin/haproxy
[root@localhost haproxy-1.5.19]# chmod +x /etc/init.d/haproxy
[root@localhost haproxy-1.5.19]# chkconfig --add /etc/init.d/haproxy
[root@localhost haproxy]# /etc/init.d/haproxy start
Starting haproxy (via systemctl): [ OK ]
[root@localhost haproxy]# systemctl stop firewalld
去游览器里搜索ip，然后刷新
3.1搭建NFS服务器
需要两台centos 7，(x1用来当作客户端 ,x4用来当作服务器）
首先在服务器上执行（Centos 7 x4）
[root@localhost ~]# yum -y install nfs-utils
centos7自带rpcbind，不用安装rpc服务
3.2启动rpc服务
因为rpc能够获得nfs服务器端的端口号等信息，nfs服务器端通过rpc获得这些信息后才能连接nfs服务器端
[root@localhost ~]# ss -tnulp | grep 111 //查看rpc有没有启动
[root@localhost ~]# systemctl start rpcbind //启动rpc
[root@localhost ~]# rpm -qa nfs-utils //查看是否安装成功
编辑/etc/exports，添加/data 192.168.1.0/24(rw,async)保存
[root@localhost ~]# vim /etc/exports
/data 192.168.52.0/24(rw,async)
~
~
~
~
~ 
3.3启动nfs服务
[root@localhost ~]# systemctl start nfs //启动nfs服务
[root@localhost ~]# rpcinfo -p 192.168.52.151 //查看nfs服务
program vers proto port service

[root@localhost ~]# 使用showmount -e localhost挂载
[root@localhost ~]# showmount -e localhost
Export list for localhost:
/data 192.168.52.0/24
创建/data目录添加文件,更改权限
[root@localhost ~]# mkdir /data
[root@localhost ~]# touch /data/1.txt
[root@localhost ~]# echo "hello nfs" >> /data/1.txt
[root@localhost ~]# chown -R nfsnobody.nfsnobody /data3.4客户端
[root@localhost ~]# yum -y intall nfs-utils
已加载插件：fastestmirror, langpacks
没有该命令：intall。请使用 /usr/bin/yum --help //查看rpc服务
[root@localhost ~]# ss -tnulp | grep 111
udp UNCONN 0 0 *:111 *:* users:(("rpcbind",pid=697,fd=6))
udp UNCONN 0 0 [::]:111 [::]:* users:(("rpcbind",pid=697,fd=9))
tcp LISTEN 0 128 *:111 *:* users:(("rpcbind",pid=697,fd=8))
tcp LISTEN 0 128 [::]:111 [::]:* users:(("rpcbind",pid=697,fd=11))
[root@localhost ~]# showmount -e 192.168.52.151
Export list for 192.168.52.151:
/data 192.168.52.0/24挂载到本地/mnt目录
[root@localhost ~]# mount -t nfs 192.168.52.151:/data /mnt
[root@localhost ~]# ls /mnt/
1.txt
[root@localhost ~]# echo "1234" >> /mnt/1.txt
[root@localhost ~]# 1.txt可以读写，nfs挂载完成。
