apache,squid,shell脚本

Posted 2020-08-23

网页重写
把所有80端口的请求重定向由https来处理
[[email protected] conf.d]# vim music.conf
<Virtualhost *:80>
        ServerName music.westos.com
        RewriteEngine on
        RewriteRule ^(/.*)$ https://%{HTTP_HOST}$1 [redirect=301]
</Virtualhost>
<Directory "/var/www/virtual/music/html">
        Require all granted
</Directory>
<Virtualhost *:443>
        ServerName music.westos.com
        DocumentRoot /var/www/virtual/music/html
        Customlog logs/news-443.log     combined
        SSLEngine on
        SSLCertificateFile /etc/pki/tls/certs/www.westos.com.crt
        SSLCertificateKeyFile /etc/pki/tls/private/www.westos.com.key
</Virtualhost>
测试成功，浏览器输入http://music.westos.com 自动跳转https://music.westos.com

apache支持的语言测试，可安装http-manual参考测试方法，可下载中文版手册
php语言测试
[[email protected] conf.d]# yum install php -y
[[email protected] conf.d]# cd /var/www/html/
[[email protected] html]# ls
file1.html  index.html
[[email protected] html]# rm -fr file1.html
[[email protected] html]# vim index.php
 <?php
phpinfo ();
?>
[[email protected] html]# systemctl restart httpd.service
输入www.westos.com进行测试

cgi脚本测试
[[email protected] html]# mkdir cgi
[[email protected] html]# ls
cgi  index.php
[[email protected] html]# cd cgi/ ##编辑如下
[[email protected] cgi]# vim index.cgi
#!/usr/bin/perl
print "Content-type: text/html\n\n";
print `date`;
[[email protected] cgi]# perl index.cgi             ###测试脚本是否成功
[[email protected] cgi]# chmod +x index.cgi
[[email protected] conf.d]# vim default.conf  #编辑如下
<Virtualhost _default_:80>
        DocumentRoot /var/www/html
        Customlog logs/default.log      combined
</Virtualhost>
<Directory "/var/www/html/cgi">
        Options +ExecCGI
        AddHandler cgi-script .cgi
</Directory>
浏览器输入172.25.254.16/cgi/inde 测试
显示时间，刷新网页时间随之刷新

##搭建论坛
[[email protected] conf.d]# systemctl start mariadb         ###启动数据库服务，并查看状态
[[email protected] conf.d]# systemctl status mariadb.service
[[email protected] conf.d]# netstat -antlpe | grep mysql   ###查看数据库开放端口，27端口已关闭无需设定，若端口打开状态 。vim /etc/my.cnf 添加skip-networking=1
（也可用软件XAMPP（Apache+MySQL+PHP+PERL）代替以上环境，进行论坛的下一步搭建
在网络上下载discuz
（Crossday Discuz! Board 简称 Discuz!是一套通用的社区论坛软件系统，用户可以在不需要任何编程的基础上，通过简单的设置和安装，在互联网上搭建起具备完善功能、很强负载能力和可高度定制的论坛服务
[[email protected] discuz3.2]# cp -p upload discuz-3.2 -r
[[email protected] discuz3.2]# ls
discuz-3.2  Discuz_X3.2_SC_GBK.zip  readme  upload  utility
[[email protected] discuz3.2]# mv discuz-3.2 /var/www/html/
浏览器输入http://172.25.254.16/discuz-3.2/install/进行安装
结果如下，出现乱码

可能是下载版本不对。此版本为简体中文GBK，改换简体中文UTF8重复以上步骤尝试
问题解决

提示不可写，给discuz目录及其子文件下放权限

[[email protected] html]# chmod 777 discuz-3.2
[[email protected] html]# chmod 777 discuz-3.2 -R
安装成功，结果如下

#############squid代理服务器
[[email protected] ~]# yum install squid -y
[[email protected] ~]# vim /etc/squid/squid.conf
 56 http_access allow all
 62 cache_dir ufs /var/spool/squid 100 16 256
[[email protected] ~]# cd /var/spool/
[[email protected] spool]# ls
abrt-upload  at    cups  mail      postfix  squid
anacron      cron  lpd   plymouth  rhsm     up2date
[[email protected] spool]# cd squid/
[[email protected] squid]# ls
[[email protected] squid]# systemctl start squid
[[email protected] squid]# ls              ###启动squid服务后自动生成目录
00  01  02  03  04  05  06  07  08  09  0A  0B  0C  0D  0E  0F  swap.state
[[email protected] squid]# netstat -antlpe | grep squid
tcp6       0      0 :::3128                 :::*                    LISTEN      0          74443      8240/(squid-1)      
[[email protected] ~]# firefox &        ###打开浏览器，设置代理服务器ip
 (Edit--Preferences--Advanced--Network--Settings..Manual proxy configuration
  输入squid服务器ip，及开放端口3128 。如下

用虚拟机连接网络成功
[[email protected] ~]# ping www.baidu.com
ping: unknown host www.baidu.com
 (ping不通，但是可以连接网络
###反向代理
[[email protected] ~]# yum remove httpd -y
[[email protected] ~]# rpm -ql httpd
package httpd is not installed
[[email protected] ~]# yum install squid -y
[[email protected] ~]# cat /var/www/html/index.html
This page shows 172.25.254.116‘s information
[[email protected] ~]# systemctl restart httpd.service   ##创建父级服务器环境
[[email protected] ~]# vim /etc/squid/squid.conf   ##配置反向代理服务器ip
 56 http_access allow all
 57
 58 # Squid normally listens to port 3128
 59 http_port 80 vhost vport
 60 cache_peer 172.25.254.116  parent 80 0 no-query
 61 # Uncomment and adjust the following to add a disk cache directory.
 62 cache_dir ufs /var/spool/squid 100 16 256
[[email protected] Desktop]# systemctl restart squid.service
在foundation37主机（第客户端主机）中输入使用反向代理服务的主机ip，获得父级服务器共享内容

##轮询
[[email protected] Desktop]# vim /etc/squid/squid.conf   ##
 60 cache_peer 172.25.254.116  parent 80 0 no-query originserver round-robin name=web1
 在下行编辑，加入另一父级服务器ip及名称即可
每次刷新，跳转不同的ip，以减缓服务器压力
