Centos7 nginx配置基于多个IP的虚拟主机

痛定思痛。 2022-05-30 23:29 209阅读 0赞

## 系统环境： ##

[root@localhost ~]# cat /etc/redhat-release 
    CentOS Linux release 7.2.1511 (Core)

## 一、配置基于IP的虚拟主机 ##

1、配置网卡IP，先查看本地虚拟机ip地址，物理机IP是：192.168.80.1

[root@localhost ~]# cat  /etc/sysconfig/network-scripts/ifcfg-eno16777736
    TYPE="Ethernet"
    BOOTPROTO="static"
    NAME="eno16777736"
    DEVICE="eno16777736"
    ONBOOT="yes"
    IPADDR=192.168.80.10
    NETMASK=255.255.255.0
    GATEWAY=192.168.80.2
    DNS1=192.168.1.1

2、在我的虚机网卡eno16777736（centos6的网卡名字是eth0）设备上添加另外两个IP别名，192.168.80.11和192.168.80.12

[root@localhost ~]# vim  /etc/sysconfig/network-scripts/ifcfg-eno16777736:0

TYPE=Ethernet
    BOOTPROTO=static
    NAME=eno16777736:0
    DEVICE=eno16777736:0
    ONBOOT=yes
    IPADDR=192.168.80.11
    NETMASK=255.255.255.0
    GATEWAY=192.168.80.2

[root@localhost ~]# vim  /etc/sysconfig/network-scripts/ifcfg-eno16777736:1

TYPE=Ethernet
    BOOTPROTO=static
    NAME=eno16777736:1
    DEVICE=eno16777736:1
    ONBOOT=yes
    IPADDR=192.168.80.12
    NETMASK=255.255.255.0
    GATEWAY=192.168.80.2

修改完，重启网络服务

[root@localhost ~]# systemctl restart network

3、查看确认：

[root@localhost ~]# ip add
    1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN 
        link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
        inet 127.0.0.1/8 scope host lo
           valid_lft forever preferred_lft forever
        inet6 ::1/128 scope host 
           valid_lft forever preferred_lft forever
    2: eno16777736: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP qlen 1000
        link/ether 00:0c:29:38:cf:ef brd ff:ff:ff:ff:ff:ff
        inet 192.168.80.10/24 brd 192.168.80.255 scope global eno16777736
           valid_lft forever preferred_lft forever
        inet 192.168.80.11/24 brd 192.168.80.255 scope global secondary eno16777736:0
           valid_lft forever preferred_lft forever
        inet 192.168.80.12/24 brd 192.168.80.255 scope global secondary eno16777736:1
           valid_lft forever preferred_lft forever

4、ping测试正常

[root@localhost ~]# ping 192.168.80.11
    PING 192.168.80.11 (192.168.80.11) 56(84) bytes of data.
    64 bytes from 192.168.80.11: icmp_seq=1 ttl=64 time=0.032 ms
    64 bytes from 192.168.80.11: icmp_seq=2 ttl=64 time=0.042 ms
    ^C
    --- 192.168.80.11 ping statistics ---
    2 packets transmitted, 2 received, 0% packet loss, time 1014ms
    rtt min/avg/max/mdev = 0.032/0.037/0.042/0.005 ms
    [root@localhost ~]# ping 192.168.80.12
    PING 192.168.80.12 (192.168.80.12) 56(84) bytes of data.
    64 bytes from 192.168.80.12: icmp_seq=1 ttl=64 time=0.058 ms
    64 bytes from 192.168.80.12: icmp_seq=2 ttl=64 time=0.046 ms
    ^C
    --- 192.168.80.12 ping statistics ---
    2 packets transmitted, 2 received, 0% packet loss, time 999ms

## 二、yum 安装nginx ##

1、如果默认yum install -y nginx安装不成功就先配置yum源，否则跳过。

[root@localhost ~]# vim /etc/yum.repos.d/epel.repo
    [epel]
    name=aliyun epel
    baseurl=http://mirrors.aliyun.com/epel/7Server/x86_64/
    gpgcheck=0

2、修改nginx配置文件，默认路径是 /etc/nginx/nginx.conf（主要是黑色粗体的配置，其他不写都可以）

[root@localhost ~]# vim /etc/nginx/nginx.conf

默认IP 192.168.80.10的nginx配置

server \{

listen       80;  
        server\_name  \_;  
        root         /usr/share/nginx/html; \#网页文件存放的目录

\# Load configuration files for the default server block.  
        include /etc/nginx/default.d/\*.conf;  
  
        location / \{  
        \}  
  
        error\_page 404 /404.html;  
            location = /40x.html \{  
        \}  
  
        error\_page 500 502 503 504 /50x.html;  
            location = /50x.html \{  
        \}  
    \}

添加server1 192.168.80.11的nginx配置

server \{

listen       80;  
        server\_name  192.168.80.11;  
        root         /usr/share/nginx/server1; \#网页文件存放的目录

添加server2 192.168.80.12的nginx配置

server \{

listen       80;  
        server\_name  192.168.80.12;  
        root         /usr/share/nginx/server2;  \#网页文件存放的目录

启动服务

[root@localhost ~]# systemctl start nginx

3、添加另外两个新增IP的nginx页面。新建server\*目录，然后拷贝默认目录html里面的文件到新目录并修改网页头部内容以便区分。

server1

[root@localhost nginx]# mkdir server1
    [root@localhost nginx]# cp -R html/* server1/
    [root@localhost server1]# vim index.html

修改各自目录下的index.html

77         <h1>Welcome to <strong>server1</strong> on Fedora!</h1>

server2

[root@localhost nginx]# mkdir server2
    [root@localhost nginx]# cp -R html/* server2/
    [root@localhost server2]# vim index.html

修改各自目录下的index.html

77         <h1>Welcome to <strong>server2</strong> on Fedora!</h1>

## 三、重启服务并查看 ##

[root@localhost ~]# systemctl restart network
    [root@localhost ~]# systemctl restart nginx

网页访问成功！
