Linux系统之安装apache服务

一、检查本地系统版本

[root@node ~]# cat /etc/os-release 
NAME="CentOS Linux"
VERSION="7 (Core)"
ID="centos"
ID_LIKE="rhel fedora"
VERSION_ID="7"
PRETTY_NAME="CentOS Linux 7 (Core)"
ANSI_COLOR="0;31"
CPE_NAME="cpe:/o:centos:centos:7"
HOME_URL="https://www.centos.org/"
BUG_REPORT_URL="https://bugs.centos.org/"

CENTOS_MANTISBT_PROJECT="CentOS-7"
CENTOS_MANTISBT_PROJECT_VERSION="7"
REDHAT_SUPPORT_PRODUCT="centos"
REDHAT_SUPPORT_PRODUCT_VERSION="7"
[root@node ~]# cat /etc/centos-release
CentOS Linux release 7.6.1810 (Core) 

二、配置yum仓库

1.配置阿里的yum源

curl -o /etc/yum.repos.d/CentOS-Base.repo https://mirrors.aliyun.com/repo/Centos-vault-6.10.repo
sed -i -e '/mirrors.cloud.aliyuncs.com/d' -e '/mirrors.aliyuncs.com/d' /etc/yum.repos.d/CentOS-Base.repo

2.检查yum仓库

[root@node ~]# yum repolist all  |grep enable
base/7/x86_64                        CentOS-7 - Base             enabled: 10,072
docker-ce-stable/7/x86_64            Docker CE Stable - x86_64   enabled:    183
extras/7/x86_64                      CentOS-7 - Extras           enabled:    515
mongodb-org/7                        MongoDB Repository          enabled:    187
updates/7/x86_64                     CentOS-7 - Updates          enabled:  4,346
[root@node ~]# 

三、安装httpd软件包

1.安装httpd

[root@node ~]# yum -y install httpd
Loaded plugins: fastestmirror, langpacks
Loading mirror speeds from cached hostfile
 * base: mirrors.ustc.edu.cn
 * extras: mirrors.aliyun.com
 * updates: mirrors.aliyun.com

Complete!


2.启动httpd服务

[root@node ~]# systemctl enable --now httpd
Created symlink from /etc/systemd/system/multi-user.target.wants/httpd.service to /usr/lib/systemd/system/httpd.service.

四、新增IP地址

1.查看原有IP

[root@node conf.d]# ifconfig ens33
ens33: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
        inet 192.168.3.166  netmask 255.255.255.0  broadcast 192.168.3.255
        inet6 fe80::8a83:7297:7cb8:9934  prefixlen 64  scopeid 0x20<link>
        ether 00:0c:29:4f:3c:68  txqueuelen 1000  (Ethernet)
        RX packets 3551027  bytes 4447887320 (4.1 GiB)
        RX errors 0  dropped 0  overruns 0  frame 0
        TX packets 1082308  bytes 122960632 (117.2 MiB)
        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0


2.新增IP地址

[root@node conf.d]# ip addr add 192.168.3.164/24 dev ens33 
[root@node conf.d]# ip add |grep  ens33
2: ens33: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP group default qlen 1000
    inet 192.168.3.166/24 brd 192.168.3.255 scope global noprefixroute dynamic ens33
    inet 192.168.3.164/24 scope global secondary ens33

五、修改httpd配置文件

1.创建三个虚拟主机的根目录

 mkdir -p /var/www/web1,2,,3

2.添加网页文件内容

[root@node conf.d]# mkdir -p /var/www/web1,2,,3
[root@node conf.d]# echo "web1 service" > /var/www/web1/index.html
[root@node conf.d]# echo "web2 service" > /var/www/web2/index.html
[root@node conf.d]# echo "web3 service" > /var/www/web3/index.html

六、基于ip的虚拟主机

1.修改httpd服务配置文件

[root@node conf.d]# cat ip.conf 
#Listen 8181
<VirtualHost 192.168.3.166:80>
ServerName web1.huawei.com
DocumentRoot /var/www/web1
</VirtualHost>



<VirtualHost 192.168.3.164:80>
ServerName web2.huawei.com
DocumentRoot /var/www/web2
</VirtualHost>


#<VirtualHost *:8181>
#ServerName web3.huawei.com
#DocumentRoot /var/www/web3
#</VirtualHost>


2.重启httpd服务

 systemctl restart httpd

3.IP访问效果

[root@node conf.d]# curl 192.168.3.166
web1 service
[root@node conf.d]# curl 192.168.3.164
web2 service

七、基于端口的虚拟主机

1.修改httpd配置文件

[root@node conf.d]# cat port.conf 
Listen 8181
<VirtualHost *:8181>
ServerName web2.huawei.com
DocumentRoot /var/www/web2
</VirtualHost>



<VirtualHost *:8181>
ServerName web3.huawei.com
DocumentRoot /var/www/web3
</VirtualHost>


#<VirtualHost *:8181>
#ServerName web3.huawei.com
#DocumentRoot /var/www/web3
#</VirtualHost>





2.修改/etc/hosts


[root@node conf.d]# cat /etc/hosts
127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6
#192.168.3.166 web1.huawei.com
192.168.3.166 web2.huawei.com
192.168.3.164 web3.huawei.com

3.重启httpd服务

systemctl restart httpd

4.访问测试结果

[root@node conf.d]# curl web2.huawei.com:8181
web2 service
[root@node conf.d]# curl web3.huawei.com:8181
web3 service


5.基于域名访问测试

[root@node conf.d]# curl web3.huawei.com
web2 service
[root@node conf.d]# curl web2.huawei.com
web1 service
