1、编译安装tengine，配置虚拟主机实现api.x.com
1.1 安装相关依赖包
sudo apt-get install openssl libssl-dev libpcre3 libpcre3-dev zlib1g-dev make make-guile gcc -y
查看libpcre3是否安装：dpkg -l | grep libpcre3
1.2 创建nginx用户
<root@ubuntu181 tengine-2.3.2>#groupadd nginx
<root@ubuntu181 tengine-2.3.2>#useradd -g nginx -s /sbin/nologin nginx
<root@ubuntu181 tengine-2.3.2>#id nginx
uid=1001(nginx) gid=1001(nginx) groups=1001(nginx)
1.3 安装Tengine-2.3.2
如果需要兼容Nginx则使用之前Nginx的编译：/apps/nginx/sbin/nginx -V
<root@ubuntu181 tengine-2.3.2>#./configure --prefix=/apps/tengine-2.3.2 --user=nginx --group=nginx --with-http_ssl_module --with-http_v2_module --with-http_realip_module --with-http_stub_status_module --with-http_gzip_static_module --with-pcre --with-stream --with-stream_ssl_module --with-stream_realip_module
make && make install
创建软连接
<root@ubuntu181 tengine-2.3.2>#ln -sv /apps/tengine-2.3.2/sbin/nginx /usr/sbin/nginx
'/usr/sbin/nginx' -> '/apps/tengine-2.3.2/sbin/nginx'
1.4 配置server监听9001端口
设置页面
<root@ubuntu181 html>#echo 9001端口网页 > index.html
<root@ubuntu181 html>#cat /data/html/index.html
9001端口网页
1.5 设置api.x.com代理9001
1.6 访问api.x.com
2、配置haproxy，实现/a路径代理转发到a集群，实现/b路径代理转发到b集群
2.1 部署规划：
192.168.37.47：haproxy服务器
192.168.37.57：a集群环境
192.168.37.67：b集群环境
192.168.37.18：默认环境
2.2 haproxy安装配置
yum安装：yum install haproxy -y
修改配置文件：
[root@cent744 ~]#vim /etc/haproxy/haproxy.cfg
frontend web_prot_80
bind 0.0.0.0:80
mode http
acl web_port path_beg -i /a
acl mob_port path_beg -i /b
use_backend web_port_http_nodes if web_port
use_backend mob_port_http_nodes if mob_port
default_backend backup_nodes
backend web_port_http_nodes
server server1 192.168.37.57:80 weight 1 check port 80 inter 3s fall 2 rise 5
backend mob_port_http_nodes
server server2 192.168.37.67:80 weight 1 check port 80 inter 3s fall 2 rise 5
backend backup_nodes
server server3 192.168.37.18:80 weight 1 check port 80 inter 3s fall 2 rise 5
2.3 其他配置
2.3.1 a环境：
yum install nginx -y
cd /usr/share/nginx/html/
echo aaa > ./a/index.html
systemctl start nginx
2.3.2 b环境：
yum install nginx -y
yum install nginx -y
cd /usr/share/nginx/html/
mkdir b
echo bbb > ./b/index.html
systemctl start nginx
2.3.4 默认环境：
yum install nginx -y
cd /usr/share/nginx/html/
echo 默认 > index.html
systemctl start nginx
2.4 实现
