Linux学习计划 -2.4.Apache的管理及优化
1.Apache的作用
在web被访问时通常使用http://的方式
http:// ##超文本传输协议
http:// 超文本传输协议提供软件:
Apache
nginx
stgw
jfe
Tengine
2.Apache的安装
dnf install httpd.x86_64 -y
3.Apache的启用
systemctl enable --now httpd ##开启服务并设定服务位开机启动
firewall-cmd --list-all ##查看火墙信息
firewall-cmd --permanent --add-service=http ##在火墙中永久开启http访问
firewall-cmd --permanent --add-service=https ##在火墙中永久开启https访问
firewall-cmd --reload ##刷新火墙使设定生效
4.Apache的基本信息
服务名称: httpd
配置文件:
/etc/httpd/conf/httpd.conf ##主配置文件
/etc/httpd/conf.d/*.conf ##子配置文件
默认发布目录: /var/www/html
默认发布文件: index.html
默认端口: 80 #http
443 #https
用户: apache
日志: /etc/httpd/logs
5.Apache的基本配置
#1.Apache端口修改#
vim /etc/httpd/conf/httpd.conf
Listen 6666
firewall-cmd --permanent --add-port=6666/tcp
firewall-cmd --reload
semanage port -l | grep http
semanage port -a -t http_port_t -p tcp 6666
systemctl restart httpd
#2.默认发布文件##
vim /etc/httpd/conf/httpd.conf
DirectoryIndex westos.html index.html
systemctl restart httpd
#3.默认发布目录
vim /etc/httpd/conf/httpd.conf
DocumentRoot "/westos/html"
<Directory "/westos/html">
Require all granted
</Directory>
semanage fcontext -a -t httpd_sys_content_t '/westos(/.*)?'
restorecon -RvvF /westos/
systemctl restart httpd
firefox http://192.168.0.11
6.Apache的访问控制
#实验素材#
mkdir /var/www/html/westos
vim /var/www/html/westos/index.html
<h1>westosdir's page</h1>
firefox http://192.168.0.11/westos
#1.基于客户端ip的访问控制#
#ip白名单#
<Directory "/var/www/html/westos">
Order Deny,Allow
Allow from 192.168.0.10
Deny from All
</Directory>
#ip黑名单#
<Directory "/var/www/html/westos">
Order Allow,Deny
Allow from All
Deny from 192.168.0.10
</Directory>
#2.基于用户认证#
vim /etc/httpd/conf/httpd.conf
<Directory "/var/www/html/westos">
AuthUserfile /etc/httpd/htpasswdfile ##指定认证文件
AuthName "Please input your name and password" ##认证提示语
AuthType basic ##认证类型
Require user admin ##允许通过的认证用户 2选1
Require valid-user ##允许所有用户通过认证 2选1
</Directory>
htpasswd -cm /etc/httpd/htpasswdfile admin ##生成认证文件
注意:
当/etc/httpd/htpasswdfile存在那么在添加用户时不要加-c参数否则会覆盖源文件内容
7.Apache的虚拟主机
mkdir -p /var/www/westos.com/{news,wenku}
echo "wenku's page" >/var/www/westos.com/wenku/index.html
echo "news's page" > /var/www/westos.com/news/index.html
echo "default's page" > /var/www/html/index.html
vim /etc/httpd/conf.d/Vhost.conf
<VirtualHost _default_:80>
DocumentRoot "/var/www/html"
CustomLog logs/default.log combined
</VirtualHost>
<VirtualHost *:80>
ServerName wenku.westos.com
DocumentRoot "/var/www/westos.com/wenku"
CustomLog logs/wenku.log combined
</VirtualHost>
<VirtualHost *:80>
ServerName news.westos.com
DocumentRoot "/var/www/westos.com/news"
CustomLog logs/news.log combined
</VirtualHost>
8.Apache的语言支持
#php#
vim /var/www/html/index.php
<?php
phpinfo();
?>
dnf install php -y
systemctl restart httpd
firefox http://192.168.0.11/index.php
#cgi#
mkdir /var/www/html/cgidir
vim /var/www/html/cgidir/index.cgi
#!/usr/bin/perl
print "Content-type: text/html\n\n";
print `date`;
9.Apache的加密访问
##安装加密插件
dnf install mod_ssl -y
##生成证书
openssl genrsa -out /etc/pki/tls/private/www.westos.com.key #生成私钥
openssl req -new -key /etc/pki/tls/private/www.westos.com.key
-out /etc/pki/tls/certs/www.westos.com.csr ##生成证书签名文件
openssl x509 -req -days 365 -in /etc/pki/tls/certs/www.westos.com.csr -signkey /etc/pki/tls/private/www.westos.com.key -out /etc/pki/tls/certs/www.westos.com.crt #生成证书
x509 证书格式
-req 请求
-in 加载签证名称
-signkey /etc/pki/tls/private/www.westos.com.key
vim /etc/httpd/conf.d/vhost.conf
<VirtualHost *:80>
ServerName login.westos.com
RewriteEngine on
RewriteRule ^(/.*)$ https://%{HTTP_HOST}$1
</VirtualHost>
<VirtualHost *:443>
ServerName login.westos.com
DocumentRoot "/www/westos.com/login"
CustomLog logs/login.log combined
SSLEngine on
SSLCertificateFile /etc/pki/tls/certs/www.westos.com.crt
SSLCertificateKeyFile /etc/pki/tls/private/www.westos.com.key
</VirtualHost>
systemctl restart httpd
^(/.*)$ ##客户地址栏中输入的地址
%{HTTP_HOST} ##客户主机
$1 ##RewriteRule后面跟的第一串字符的值
10.Squid+Apache
#squid 正向代理#
实验环境:
单网卡主机设定ip不能上网
双网卡主机设定ip1可以连接单网卡主机,设定ip2可以上网
实验效果
让单网卡主机不能上网但浏览器可以访问互联网页
操作:
在双网卡主机中
dnf install squid -y
vim /etc/squid/squid.conf
59 http_access allow all
65 cache_dir ufs /var/spool/squid 100 16 256
systemctl restart squid
firewall-cmd --permanent --add-port=3128/tcp
firewall-cmd --reload
在单网卡专辑中选择
NetWork Proxy
172.25.254.30 3128
测试:
在单网卡主机中
ping www.baidu.com 不通
在浏览器中访问www.baidu.com可以
#squid反向代理#
实验环境:
172.25.254.20 ##Apache服务器
172.25.254.30 ##squid,没有数据负责缓存
vim /etc/squid/squid.conf
http_port 80 vhost vport ##vhost 支持虚拟域名 vport 支持虚拟端口
#当172.25.254.30的80端口被访问会从172.25.254.20的80端口缓存数据
cache_peer 172.25.254.20 parent 80 0 proxy-only
systemctl restart squid
