Docker 安装启动Nginx
1.搜索镜像 search
2.下载镜像 pull
3.运行测试
4. 单个tomcat 处理能力,500~600, nginx 5万
5. 反向代理, 动静分离,高性能

配置文件详解
1.nginx的相关目录
- /usr/local/nginx目录是nginx安装成功后，默认生成的目录。
- nginx的启动文件在/usr/local/nginx/sbin目录下。
- nginx的生效的主配置文件是/usr/local/nginx/conf/nginx.conf
2.nginx配置文件的结构
... #全局块
events {
#events块
...
}
http {
#http块
...
server {
#server块
...
location [PATTERN] {
#location块
...
}
location [PATTERN] {
#location块
...
}
}
server {
#server块
...
}
... #http全局块
}
3.include子配置文件
在生效的主配置文件中的http{}配置块中，用include包含其他目录的自定义配置文件，并令其生效。
(每次重新配置文件都需要重启nginx服务器或者重新加载配置文件)
worker_processes 1;
events {
worker_connections 1024;
}
http {
include /www/nginx/*.conf; # 在http的配置块中配置
include mime.types;
default_type application/octet-stream;
sendfile on;
keepalive_timeout 65;
server {
listen 80;
server_name localhost;
location / {
root html;
index index.html index.htm;
}
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root html;
}
}
}
其他目录/www/nginx/*.conf的配置文件：
server {
listen 80;
server_name localhost;
location / {
root html;
index index.html index.htm;
}
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root html;
}
}
4.配置反向代理和负载均衡(全)
worker_processes 1;
events {
worker_connections 1024;
}
http {
include mime.types;
default_type application/octet-stream;
sendfile on;
keepalive_timeout 65;
# 配置反向代理服务器的ip列表
upstream myserverlist {
server 127.0.0.1:8888 weight=1; # 负载均衡配置权重（加权轮询）
server 192.168.1.1:9999 weight=1; # # 负载均衡配置权重（加权轮询）
}
server {
listen 80;
server_name localhost;
location / {
root html;
index index.html index.htm;
# 请求myserverlist 定义的服务器列表
proxy_pass http://myserverlist ;
}
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root html;
}
}
}
5.前端静态资源部署（Server静态详情配置）
server {
listen 80;
server_name 127.0.0.1;
location /prod-api/ {
# proxy_set_header用来重定义发往后端服务器的请求头
proxy_set_header Host $http_host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header REMOTE-HOST $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_pass http://localhost:8888/;
}
location / {
root /www/dist; # 访问127.0.0.1:80地址的时候，定位到/www/dist文件夹下的首页index.html
try_files $uri $uri/ /index.html;
index index.html index.htm;
}
#error_page 404 /404.html;
# redirect server error pages to the static page /50x.html
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root html;
}
}
