{**apache**}
lamp=linux apache mysql php
lnmp=linux nginx mysql php
nginx提供共享
curl -I www.baidu.com(域名) **查看域名使用的信息
nmap 网络扫描
yum install nmap -y
nmap -A www.xupt.edu
在server上做
hostnamectl set-hostname web1.westos.com
yum install httpd -y
cd /var/www/html/
systemctl start httpd
vim /etc/httpd/conf/httpd.conf

**默认发布目录下/var/www/html/的index.html file文件，哪个在前，在浏览器中优先看哪个，若都没有，则浏览器显示界面为apache测试页面（在server浏览器中输入http://172.25.254.149，回车后可看到相应页面）
yum install httpd-manual.noarch -y **httpd使用手册
更改默认发布目录：
将默认发布目录/var/www/html/改为/www/westos
[root@web1 ~]# cd /var/www/html/
[root@web1 html]# getenforce
Enforcing
[root@web1 html]# ls -Zd .
drwxr-xr-x. root root system_u:object_r:httpd_sys_content_t:s0 .
[root@web1 html]# mkdir /www/westos -p
[root@web1 html]# semanage fcontext -a -t httpd_sys_content_t '/www/westos(/.*)?'
[root@web1 html]# restorecon -RvvF /www/
restorecon reset /www context unconfined_u:object_r:default_t:s0->system_u:object_r:default_t:s0
restorecon reset /www/westos context unconfined_u:object_r:default_t:s0->system_u:object_r:httpd_sys_content_t:s0
[root@web1 html]# cd /www/westos/
[root@web1 westos]# vim index.html 编辑内容为/www/westos's page
[root@web1 westos]# vim /etc/httpd/conf/httpd.conf 修改内容为：
119 #DocumentRoot "/var/www/html"
120 DocumentRoot "/www/westos"
121 <Directory "/www/westos">
122 require all granted
123 </Directory>
[root@web1 westos]# systemctl restart httpd.service
在server浏览器中输入http://172.25.254.149 得到 /www/westos's page 表示更改成功
查看端口：
[root@web1 westos]# ss -antlp | grep httpd
LISTEN 0 128 :::80 :::*
[root@web1 westos]# vim /etc/httpd/conf/httpd.conf
41 #Listen 12.34.56.78:80
42 Listen 80 默认为80端口
http://ip:80也可不加80一般默认
若改变为Listen 8080，则在浏览器中输入http://ip:8080
如： http://172.25.254.149:8080
访问权限黑白名单
[root@web1 westos]# vim /etc/httpd/conf/httpd.conf
120 DocumentRoot "/www/westos"
121 <Directory "/www/westos">
122 require all granted
123 Order Deny,Allow **谁在前，先读谁，一般Allow在前
124 Allow from 172.25.254.0/24 **允许172.25.254.x网段所有人访问
125 Deny from ALL **拒绝所有人访问
126 </Directory>
[root@web1 westos]# systemctl restart httpd.service
设置用户访问权限
vim /etc/httpd/conf/httpd.conf
121 <Directory "/www/westos">
122 Require all granted
123 AllowOverride all
124 Authuserfile /etc/httpd/htpasswdfile **用户信息所在文件
125 Authname "Please input username and password" **提示信息
126 Authtype basic **基本认证类型
127 Require user admin **只允许使用用户admin在浏览器中访问
128 </Directory>
systemctl restart httpd.service
若要所以用户都可访问则：
vim /etc/httpd/conf/httpd.conf
127 Require valid-user
systemctl restart httpd.service
访问需要输入用户和密码
{**apaache的虚拟主机**}
vim /etc/httpd/conf/httpd.conf先修改为初始状态
119 DocumentRoot "/var/www/html"
120 #DocumentRoot "/www/westos"
121 #
122 # Relax access to content within /var/www.
