一台虚拟机配置nginx反向代理+3个apache虚拟主机

三个虚拟主机通过一张网卡添加三个IP来实现

一、安装nginx

1.解决依赖

[root@xuegod1 ~]# yum groupinstall "Development Tools" "Development Libraries" -y

[root@xuegod1 ~]# yum install gcc gcc-c++ autoconf automake zlib zlib-devel openssl openssl-devel pcre* pcre-devel -y

Zlib：Nginx提供gzip模块，需要zlib的支持

Openssl：Nginx提供SSL的功能

[root@xuegod1 ~]# tar xf pcre-8.37.tar.bz2 -C /usr/local/src/  //解压此安装包即可，不需要安装，Nginx需要指定pcre的源码不是安装后的路径，此包的功能是支持地址重写rewrite功能 pcre的依赖可以yum安装pcre和pcre-devel解决！

2.解压编译安装

[root@xuegod1 nginx-1.8.0]# tar xvf nginx-1.8.0.tar.gz -C /usr/local/src/ ; cd /usr/local/src/nginx-1.8.0

[root@xuegod1 nginx-1.8.0]# ./configure --prefix=/usr/local/nginx --with-http_dav_module --with-http_stub_status_module --with-http_addition_module --with-http_sub_module --with-http_flv_module --with-http_mp4_module --with-pcre=/usr/local/src/pcre-8.37/

[root@xuegod1 ~]# make -j 4 ; make install ; cd

[root@xuegod1 ~]# useradd -M -u 8001 -s /sbin/nologin nginx  //用于运行Nginx的用户

3.配置Nginx支持php文件

[root@xuegod1 ~]# vim /usr/local/nginx/conf/nginx.conf  //Nginx主配置文件

#user  nobody;

user nginx nginx；    //添加此行

并在所支持的主页面格式中添加php格式的主页，类似如下：

location / {

root html;

index index.php index.html index.htm;

}

#location ~ \.php$ {

# root html;

# fastcgi_pass 127.0.0.1:9000;

# fastcgi_index index.php;

# fastcgi_param SCRIPT_FILENAME /scripts$fastcgi_script_name;

# include fastcgi_params;

#} #找到上面这段内容，将这段内容复制，去掉#且修改为如下

location ~ \.php$ {

root html;

fastcgi_pass 127.0.0.1:9000;

fastcgi_index index.php;

fastcgi_param SCRIPT_FILENAME  /usr/local/nginx/html$fastcgi_script_name; #将scripts修改为nginx的html，即Nginx页面目录，因为要处理的php文件也在这个目录下

include fastcgi_params;

}

4.启动Nginx

[root@xuegod1 ~]# /usr/local/nginx/sbin/nginx

[root@xuegod1 ~]# netstat -tlnp|grep nginx

tcp        0      0 0.0.0.0:80                  0.0.0.0:*                   LISTEN      11786/nginx

使用浏览器测试 http://192.168.10.31

二、安装apache和php

[root@xuegod44 conf]# yum install php httpd -y

1.配置网卡

[root@xuegod44 network-scripts]# cp ifcfg-eth0 ifcfg-eth0:1

[root@xuegod44 ~]# cd /etc/sysconfig/network-scripts/
[root@xuegod44 network-scripts]#ifcfg-eth0:1

DEVICE=eth0:1
TYPE=Ethernet
ONBOOT=yes
NM_CONTROLLED=yes
BOOTPROTO=none
IPADDR=192.168.10.51
NETMASK=255.255.255.0

[root@xuegod44 network-scripts]# cp ifcfg-eth0:1 ifcfg-eth0:2

[root@xuegod44 network-scripts]# cp ifcfg-eth0:1 ifcfg-eth0:3

[root@xuegod44 network-scripts]# vim ifcfg-eth0:2

DEVICE=eth0:2
TYPE=Ethernet
ONBOOT=yes
NM_CONTROLLED=yes
BOOTPROTO=none
IPADDR=192.168.10.52
NETMASK=255.255.255.0

[root@xuegod44 network-scripts]# vim ifcfg-eth0:3

DEVICE=eth0:3
TYPE=Ethernet
ONBOOT=yes
NM_CONTROLLED=yes
BOOTPROTO=none
IPADDR=192.168.10.53
NETMASK=255.255.255.0

[root@xuegod44 network-scripts]# service network restart

[root@xuegod44 network-scripts]# ifconfig

2.配置apache

[root@xuegod44 ~]# cd /var/www/html/
[root@xuegod44 html]# mkdir a
[root@xuegod44 html]# mkdir b
[root@xuegod44 html]# mkdir c
[root@xuegod44 html]# echo "192.168.10.51" > a/index.html
[root@xuegod44 html]# echo "192.168.10.52" > b/index.html
[root@xuegod44 html]# echo "192.168.10.53" > c/index.html

[root@xuegod44 ~]# vim /etc/httpd/conf/httpd.conf

Listen 81

<VirtualHost 192.168.10.51:81>
ServerAdmin webmaster@dummy-host.example.com
DocumentRoot /var/www/html/a
ServerName xuegod44
ErrorLog logs/dummy-host.example.com-error_log
CustomLog logs/dummy-host.example.com-access_log common
</VirtualHost>
<VirtualHost 192.168.10.52:81>
ServerAdmin webmaster@dummy-host.example.com
DocumentRoot /var/www/html/b
ServerName xuegod44
ErrorLog logs/dummy-host.example.com-error_log
CustomLog logs/dummy-host.example.com-access_log common
</VirtualHost>
<VirtualHost 192.168.10.53:81>
ServerAdmin webmaster@dummy-host.example.com
DocumentRoot /var/www/html/c
ServerName xuegod44
ErrorLog logs/dummy-host.example.com-error_log
CustomLog logs/dummy-host.example.com-access_log common
</VirtualHost>

三、配置nginx

[root@xuegod44 ~]# vim /usr/local/nginx/conf/nginx.conf

第二行添加

user nginx nginx;

server {
listen 80;
server_name localhost;

#charset koi8-r;

#access_log logs/host.access.log main;

location / {          #添加
root html;
index index.html index.htm;
if ($request_uri ~* \.html$) {
proxy_pass http://htmlservers;
}
if ($request_uri ~* \.php$) {
proxy_pass http://phpservers;
}
proxy_pass http://pciservers;

}

#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;
}

# proxy the PHP scripts to Apache listening on 127.0.0.1:80
#
#location ~ \.php$ {
# proxy_pass http://127.0.0.1;
#}

# pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
#
#location ~ \.php$ {
# root html;
# fastcgi_pass 127.0.0.1:9000;
# fastcgi_index index.php;
# fastcgi_param SCRIPT_FILENAME /scripts$fastcgi_script_name;
# include fastcgi_params;
#}
#location ~ \.php$ {
# # proxy_pass http://127.0.0.1;
# #}
#
# # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
# #
location ~ \.php$ {
root html;
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;

fastcgi_param SCRIPT_FILENAME /usr/local/nginx/html$fastcgi_script_name;
include fastcgi_params;
}
}
upstream htmlservers {               #server模块外添加
    server 192.168.10.51:81;
    server 192.168.10.52:81;
    server 192.168.10.53:81;
}
upstream phpservers {
   server 192.168.10.51:81;
   server 192.168.10.52:81;
   server 192.168.10.53:81;
 }
upstream pciservers {
    server 192.168.10.51:81;
   server 192.168.10.52:81;
   server 192.168.10.53:81;
  }
# deny access to .htaccess files, if Apache's document root
# concurs with nginx's one
#
#location ~ /\.ht {
# deny all;
#}

4.测试

使用浏览器访问http://192.168.10.44

刷新一次

再刷新一次

备注：apache这里不能用80端口，否则会与nginx冲突，因为nginx先占用了80端口。如果apache用80端口会报如下错误
