一.在静态服务器上查看
[root@yum-n opt]# ls
king.jpg qf.css qf.png
二. 配置静态服务器
备份原来的配置文件，之后创建如下两个新的文件，没有的目录请自行创建。
user nginx;
worker_processes 1;
error_log /var/log/nginx/error.log warn;
pid /var/run/nginx.pid;
events {
worker_connections 1024;
}
http {
include /etc/nginx/mime.types;
default_type application/octet-stream;
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;
keepalive_timeout 65;
include /etc/nginx/conf.d/*.conf;
}
server {
listen 80;
server_name localhost;
#charset koi8-r;
#access_log /var/log/nginx/host.access.log main;
# 请求的静态资源到本地的 /opt/ 目录下获取
location ~ \.(png|jpg|gif|css|js)$ {
root /opt/;
}
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root /usr/share/nginx/html;
}
}
重启Nginx服务
YUM 安装重启方式
systemctl restart nginx
编译安装重启方式
nginx -s stop # 先停止服务
nginx # 再启动服务
三. 操作动态网站服务器
修改动态网站服务器程序代码
image
配置wsgi.py
[root@mpn-salve webapp]# vim wsgi.py
headers = {
'text': ('Content-Type', 'text/plain;charset=utf-8'),
'html': ('Content-Type', 'text/html;charset=utf-8'),
'json': ('Content-Type', 'application/json;charset=utf-8'),
'js': ('Content-Type', 'application/javascript'),
'css': ('Content-Type', 'text/css'),
'jpg': ('Content-Type', 'application/x-jpg'),
'png': ('Content-Type', 'image/png'),
}
import views
def application(env, start_response):
if env['PATH_INFO'] == '/':
start_response('200 OK', [headers['text']])
content = views.qf_index()
return [b'hello']
elif env['PATH_INFO'] == '/api/json':
start_response('200 OK', [headers['json']])
content = views.qf_json()
print("==>",content)
return [content]
elif env['PATH_INFO'] == '/info':
start_response('200 OK', [headers['html']])
content = views.info()
return [content]
配置qf-uwsgi.ini
[root@mpn-salve webapp]# cat qf-uwsgi.ini
[uwsgi]
socket = 0.0.0.0:9090
chdir = /opt/webapp/
wsgi-file = wsgi.py
processes = 4
threads = 2
stats = 127.0.0.1:9191
配置views.py
[root@mpn-salve webapp]# cat views.py
import json
def qf_index():
return bytes("hello", encoding='utf-8')
def qf_json():
data = {"name": "shark", "age": 18}
return bytes(json.dumps(data), encoding='utf-8')
def info():
with open('info.html', 'rb') as f:
html = f.read()
return html
def qf_logo():
with open('qf.png', 'rb') as f:
img = f.read()
return img
def king():
with open('king.jpg', 'rb') as f:
img = f.read()
return img
def handle_css():
with open('qf.css', 'rb') as f:
css = f.read()
return css
配置info.html
[root@mpn-salve webapp]# vim info.html
<!DOCTYPE html>
<html lang="zh-CN">
<head>
<meta charset="utf-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge">
<meta name="viewport" content="width=device-width, initial-scale=1">
<!-- 上述3个meta标签*必须*放在最前面，任何其他内容都*必须*跟随其后！ -->
<title>测试一下</title>
<link rel="stylesheet" type="text/css" href="/qf.css">
</head>
<body>
<h1>走一走</h1>
<img src="/king.jpg" alt="金鼠送福" class="img-rounded">
<h2 class="bg-danger">看一看</h2>
<table class="table ">
<thead>
<tr>
<th>序号</th>
<th>姓名</th>
<th>年龄</th>
</tr>
</thead>
<tbody>
<tr>
<th scope="row">1</th>
<td>{name}</td>
<td>{age}</td>
</tr>
</tbody>
</table>
</body>
</html>
创建php文件 /ding/ 目录下
[root@mpn-salve ding]# vim /ding/index.php
<?php
echo phpinfo();
?>
配置动态服务器
[root@mpn-salve webapp]# vim /etc/nginx/nginx.conf
user nginx;
worker_processes 1;
pid /var/run/nginx.pid;
events {
worker_connections 1024;
}
http {
include mime.types;
default_type application/octet-stream;
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;
keepalive_timeout 65;
server {
listen 80;
server_name localhost;
location ~ \.php$ {
root /ding/;
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
include fastcgi_params;
}
}
}
五. 启动此网站程序
[root@mpn-salve webapp]# uwsgi qf-uwsgi.ini
六. 配置负载均衡器
# vim /etc/nginx/nginx.conf
user nginx;
worker_processes 2;
worker_rlimit_nofile 102400;
events {
worker_connections 1024;
}
http {
include mime.types;
default_type application/octet-stream;
upstream static {
server 10.3.134.111;
}
upstream python {
server 10.3.134.99:9090;
}
upstream php {
server 10.3.134.99;
}
server {
listen 80;
server_name www.ddd.com;
location ~ \.(png|jpg|gif|css|js)$ {
proxy_pass http://static;
}
location ~ \.php$ {
proxy_pass http://php;
}
location ~ \.php$ {
proxy_pass http://php;
}
location / {
include uwsgi_params;
uwsgi_pass python;
}
}
}
七. 启动负载均衡器服务
7.1 YUM 安装重启方式
systemctl restart nginx
7.2 编译安装重启方式
nginx -s stop # 先停止服务
nginx # 再启动服务
八. 浏览器访问负载均衡器的地址
http://10.3.134.72/info
