编写nginx服务配置文件
nginx配置文件三个语法格式说明：1. 大括号要成对出现2. 每一行指令后面要用分号结尾3. 每一个指令要放置在指定的区块中虚拟主机配置文件编写方法：1. 基于域名的虚拟主机配置方法（最常用）2. 基于端口的虚拟主机配置方法 说明：当你访问的网站域名在虚拟主机配置中不存在时，默认会将第一个虚拟主机的配置页面响应给用户3. 基于IP地址的虚拟主机配置方法 说明：nginx服务中只要涉及IP地址的修改，都需要重启nginx服务，而不能采用平滑重启
实现编写一个或多个网站页面(基于域名)
#1.编写配置文件[root@web01 html]# cat ../conf/nginx.confworker_processes 1;events { worker_connections 1024;}http { include mime.types; default_type application/octet-stream; sendfile on; keepalive_timeout 65; server { listen 80; server_name www1.etiantian.org; location / { root html/www; index index.html index.htm; } error_page 500 502 503 504 /50x.html; location = /50x.html { root html; } } server { listen 80; server_name bbs.etiantian.org; location / { root html/bbs; index index.html index.htm; } error_page 500 502 503 504 /50x.html; location = /50x.html { root html; } } server { listen 80; server_name blog.etiantian.org; location / { root html/blog; index index.html index.htm; } error_page 500 502 503 504 /50x.html; location = /50x.html { root html; } }}#2.生成站点目录与首页文件[root@web01 html]# for i in www bbs blog;do echo "10.0.0.7 $i.etiantian.org" > /application/nginx/html/$i/index.html;done[root@web01 html]# for i in www bbs blog;do cat /application/nginx/html/$i/index.html;done10.0.0.7www.etiantian.org10.0.0.7 bbs.etiantian.org10.0.0.7 blog.etiantian.org#3.访问测试[root@web01 html]# curl www1.etiantian.org10.0.0.7 www.etiantian.org[root@web01 html]# curl bbs.etiantian.org10.0.0.7 bbs.etiantian.org[root@web01 html]# curl blog.etiantian.org10.0.0.7 blog.etiantian.org[root@web01 html]# 实现编写一个或多个网站页面(基于端口)
#编写配置文件，更改访问端口[root@web01 html]# cat ../conf/nginx.confworker_processes 1;events { worker_connections 1024;}http { include mime.types; default_type application/octet-stream; sendfile on; keepalive_timeout 65; server { listen 8080; server_name www1.etiantian.org; location / { root html/www; index index.html index.htm; } error_page 500 502 503 504 /50x.html; location = /50x.html { root html; } } server { listen 8081; server_name bbs.etiantian.org; location / { root html/bbs; index index.html index.htm; } error_page 500 502 503 504 /50x.html; location = /50x.html { root html; } } server { listen 8082; server_name blog.etiantian.org; location / { root html/blog; index index.html index.htm; } error_page 500 502 503 504 /50x.html; location = /50x.html { root html; } }}#访问测试[root@web01 html]# curl www1.etiantian.org:808010.0.0.7 www.etiantian.org[root@web01 html]# curl www1.etiantian.org:808110.0.0.7 bbs.etiantian.org[root@web01 html]# curl www1.etiantian.org:808210.0.0.7 blog.etiantian.org 实现编写一个或多个网站页面(基于IP)
#编写配置文件，因IP只有一个，所以只能一个做测试[root@web01 html]# cat ../conf/nginx.confworker_processes 1;events { worker_connections 1024;}http { include mime.types; default_type application/octet-stream; sendfile on; keepalive_timeout 65; server { listen 80; server_name 10.0.0.7; location / { root html/www; index index.html index.htm; } error_page 500 502 503 504 /50x.html; location = /50x.html { root html; } }}#测试[root@web01 html]# curl 10.0.0.710.0.0.7 www.etiantian.org 企业实用案例：每个网站目录配置文件进行分割
