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]

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

##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] ~]# 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

Apache Hadoop 3.0.0-alpha1，重写 Shell 脚本

Apache Hadoop 3.0.0-alpha1发布了. 部分更新内容: Hadoop 3.0.0-alpha1在Java 8下编译,使用Java 7以及以下版本需更新到Java 8 重写了shell脚本,支持超过两个NameNode 详情请参照发行说明: Hadoop 3.0.0-alpha1 Release Notes 主页:http://hadoop.apache.org/docs/r3.0.0-alpha1/index.html 下载:http://hadoop.apache.org

shell脚本分析apache日志状态码

一.首先将apache日志按天切割 vi /etc/httpd/conf/httpd.confErrorLog "|rotatelogs /var/log/httpd/%Y%m%derror_log 86400 480″CustomLog "|rotatelogs /var/log/httpd/%Y%m%daccess_log 86400 480″ combined 二.重启apache服 service httpd restart ##################apahce日志

SDK/JDK，Shell/Shell脚本，Apache/APR ,MTK

SDK 软件开发工具包(SoftwareDevelopmentKit) API(Application Programming Interface,应用编程接口)其实就是操作系统留给应用程序的一个调用接口,应用程序通过调用操作系统的 API而使操作系统去执行应用程序的命令(动作). Android SDK 指的是Android专属的软件开发工具包 DLL,即 Dynamic Link Library(动态链接库).在 Windows 环境下含有大量 .dll格式的文件,.dll 文件不能直接执行

Apache下通过shell脚本提交网站404死链

网站运营人员对于死链这个概念一定不陌生,网站的一些数据删除或页面改版等都容易制造死链,影响用户体验不说,过多的死链还会影响到网站的整体权重或排名. 百度站长平台提供的死链提交工具,可将网站存在的死链(协议死链.404页面)进行提交,可快速删除死链,帮助网站SEO优化.在提交死链的文件中逐个手动填写死链的话太麻烦,工作中我们提倡复杂自动化,所以本文我们一起交流分享Apache服务中通过shell脚本整理网站死链,便于我们提交. 1.配置Apache记录搜索引擎 Apache是目前网站建设最为主流的

shell脚本自动编译安装Apache

shell脚本自动安装Apache,适用于CentOS #!/bin/bash ##################################################### #Create date 2018.4.10 #Author: wansheng #Function: shell script install apache2.4 #Email: [email protected]  #System: Linux CentOS-7 ######################

shell脚本写apache并能通过浏览器访问！

第一步:导入httpd-2.2.17.tar包 第二步:创建一个test.sh文件(可在/root下) 第三步编写shell脚本 > 会重写文件,如果文件里面有内容会覆盖 >>这个是将输出内容追加到目标文件中.如果文件不存在,就创建文件 #!/bin/bash //bin/bash解释器 tar xf httpd-2.2.17.tar.gz -C /usr/src > /dev/null //dev/null:代表黑洞,不会输出出来 yum -y install gcc gcc-c

Apache日志切割shell脚本

Apache.Nginx等web服务器日志量巨大,如果不进行切割的话会导致日志文件过大,不容易清理,而且给日志分析收集工作带来麻烦.下例为Apache日志切割脚本,nginx等其他web服务同样适用 代码: #!/bin/bash apache_log_path="/usr/local/apache/logs"     #指定日志存储位置 log_filenames=`/bin/ls $apache_log_path` save_days=7  #定义保留7天内日志 #按照日期时间存储

Shell脚本——正则表达式

正则表达式的概念 正则表达式:使用单个字符串来描述.匹配一系列符合某个句法规则的字符串由普通字符与特殊字符组成,一般用在脚本编程.文本编辑器中,如php.python.she等,简写为regex.regexp. 用来检索.替换符合模式的文本,具有强大的文本匹配功能能够在文本海洋中快速高效地处理本文 基础正则表达式 正则表达式的字符串表达方法根据不同的严谨程度与功能分为基本正则表达式与扩展正则表达式.基础正则表达式是常用的正则表达式的最基础的部分.在 Linux 系统中常见的文件处理工具中 gre
