业务需求:单独部署Apache服务来做图片服务器
1.环境:
1.1腾讯云主机,初始化安装环境,最小化安装centos7.4 x86_64位 系统版本:
[root@VM_82_178_centos conf]# cat /etc/redhat-release
CentOS Linux release 7.4.1708 (Core)
1.2httpd服务安装方式:yum 安装 yum install httpd -y httpd源码包下载地址: http://archive.apache.org/dist/httpd/
httpd服务版本:
[root@VM_82_178_centos conf]# httpd -v
Server version: Apache/2.4.6 (CentOS)
Server built: Jun 27 2018 13:48:59
提示:只需要安装apache服务足够提供图片服务器应用了
1.3开启Rewrite功能模块: 说明:在centos7的系统上,yum安装httpd服务,默认安装的apache服务的版本是2.4.6,它默认已经安装好了支持Rewrite功能模块
[root@VM_82_178_centos ~]# find / -name mod_rewrite.so
/usr/lib64/httpd/modules/mod_rewrite.so
补充:在centos6的系统上,yum安装httpd服务,默认安装的apache服务的版本是2.2.15
并且默认已经在配置文件/etc/httpd/conf.modules.d/00-base.conf 中加载了这个模块LoadModule rewrite_module modules/mod_rewrite.so
[root@VM_82_178_centos conf.modules.d]# grep mod_rewrite.so /etc/httpd/conf.modules.d/00-base.conf
LoadModule rewrite_module modules/mod_rewrite.so
并且Apache/2.4.6 默认支持的模块为101个,而apache2.2.x以下版本默认才支持61个模块
2、apache不同版本开启rewrite功能介绍:
在apache1.x版本和apache2.2.x版本以及apache2.4.x开启rewrite功能的方式是不一样的
2.1、 Apache 1.x
Apache 1.x 的用户请检查 conf/httpd.conf 中是否存在如下两段代码:
LoadModule Rewrite_module libexec/mod_Rewrite.so
AddModule mod_Rewrite.c
** Apache 1.x版本配置Apache配置文件httpd.conf实现rewrite** 找到
<IfModule mod_Rewrite.c>
</IfModule>
没有的自己添加,然后之间写入你的rewrite规则,例如:
<IfModule mod_Rewrite.c>
RewriteEngine On
RewriteRule ^q/[0-9]+/(.*)$ /uploads/picture/$1 [L]
</IfModule>
<VirtualHost *:80>
DocumentRoot "/data/www/images"
ServerName img.yb898.cn
ServerAlias img.yb898.cn
ErrorLog "logs/img.yb898.cn-error_log"
CustomLog "logs/img.yb898.cn-access_log" common
<Directory "/data/www/images">
#Options Indexes FollowSymlinks
Options FollowSymlinks
##Allowoverride All
Allowoverride None
Order Allow,Deny
Allow from all
<IfModule mod_Rewrite.c>
RewriteEngine On
RewriteRule ^q/[0-9]+/(.*)$ /uploads/picture/$1 [L]
</IfModule>
</Directory>
</VirtualHost>
注意:如果网站使用通过虚拟主机来定义,请务必加到虚拟主机配置,即 <VirtualHost> 中去,如果加在虚拟主机配置外部将可能无法使用
2.2、 Apache 2.2.15
Apache 2.2.15版本的用户请检查 conf/httpd.conf 中是否存在如下一段代码:
LoadModule Rewrite_module modules/mod_rewrite.so
注:如果前面有#,将其去掉。并且保证你的apache文件里有mod_rewrite.so文件(1.X版的要有mod_rewrite.c)。
<VirtualHost *:80>
DocumentRoot "/data/www/images"
ServerName img.yb898.cn
ServerAlias img.yb898.cn
ErrorLog "logs/img.yb898.cn-error_log"
CustomLog "logs/img.yb898.cn-access_log" common
<Directory "/data/www/images">
#Options Indexes FollowSymlinks
Options FollowSymlinks
##Allowoverride All
Allowoverride None
Order Allow,Deny
Allow from all
</Directory>
</VirtualHost>
2.3 apache2.4.6版本:
(已经测试验证是成功的)
<VirtualHost *:80>
DocumentRoot "/data/www/images"
ServerName img.yb898.cn
ServerAlias img.yb898.cn
ErrorLog "logs/img.yb898.cn-error_log"
CustomLog "logs/img.yb898.cn-access_log" common
<Directory "/data/www/images">
#Options Indexes FollowSymlinks
Options FollowSymlinks
Require all granted
RewriteEngine on
RewriteRule ^q/[0-9]+/(.*)$ /uploads/picture/$1 [L]
RewriteRule ^[0-9]+.([0-9]+).([0-9]+).([0-9]+).(.*)$ /uploads/picture/$1/$2/$3/$4 [L]
</Directory>
</VirtualHost>
浏览器请求链接:
http://img.yb898.cn/q/12345/2016/07/28/1520924032.png http://img.yb898.cn/12345.2016.07.28/1520924032.png http://img.yb898.cn/uploads/picture/2016/07/28/1520924032.png
文件存放路径:
[root@VM_82_178_centos images]# ll /data/www/images/uploads/picture/2016/07/28/1520924032.png
-rw-r--r-- 1 root root 89032 Mar 13 14:53 /data/www/images/uploads/picture/2016/07/28/1520924032.png
提示: 一个常见的问题:配置完rewrite后有时会显示Forbidden You don't have permission to access /data/www/images on this server.这样的错误。 加上Options FollowSymLinks就行了,注意不能加Indexes,这个表示显示目录(根目录没有index.html的情况下就显示文件夹的目录结构)。
3.让apache支持.htaccess
3.1对于apache1.x的版本:
把<IfModule mod_Rewrite.c>
RewriteEngine On
RewriteRule ^q/[0-9]+/(.*)$ /uploads/picture/$1 [L]
</IfModule>
里的代码删除掉
找到#AccessFileName .htaccess把前面的#注释去掉
找到:
<VirtualHost *:80>
DocumentRoot "/data/www/images"
ServerName img.yb898.cn
ServerAlias img.yb898.cn
ErrorLog "logs/img.yb898.cn-error_log"
CustomLog "logs/img.yb898.cn-access_log" common
<Directory "/data/www/images">
#Options Indexes FollowSymlinks
Options FollowSymlinks
#Allow Override All
Allowoverride None
Order Allow,Deny
Allow from all
</Directory>
</VirtualHost>
把里边的AllowOverride None 改为 Allow Override All 这样.htaccess文件才能启用。
3.2、对于apache2.x的版本
找到#AccessFileName .htaccess把前面的#注释去掉 找到:
<VirtualHost *:80>
DocumentRoot "/data/www/images"
ServerName img.yb898.cn
ServerAlias img.yb898.cn
ErrorLog "logs/img.yb898.cn-error_log"
CustomLog "logs/img.yb898.cn-access_log" common
<Directory "/data/www/images">
#Options Indexes FollowSymlinks
Options FollowSymlinks
Allowoverride All
Require all granted
</Directory>
</VirtualHost>
把参数 Allowoverride All添加上,这样.htaccess文件才能启用。
3.3、针对apache2.4.6举例:
RewriteEngine on
RewriteRule ^q/[0-9]+/(.*)$ /uploads/picture/$1 [L]
直接把上面的代码写入到.htaccess文件,并且把.htaccess文件放到站点或者图片的根目录下,重启apache就行了。
[root@VM_82_178_centos images]# cat /data/www/images/.htaccess
RewriteEngine on
RewriteRule ^q/[0-9]+/(.*)$ /uploads/picture/$1 [L]
RewriteRule ^[0-9]+.([0-9]+).([0-9]+).([0-9]+).(.*)$ /uploads/picture/$1/$2/$3/$4 [L]
为了安全起见,在httpd.conf文件添加如下参数禁止.htaccess文件通过浏览器请求被下载
<Files ".ht*">
Require all denied
#Require all granted
</Files>
一般的apache以上配置就行了,但我的还不行,所以研究了一下apache的配置文件httpd.conf发现了这样一个参数: ** AccessFileName ht.access** ** 意思是:**AccessFileName定义每个目录下的访问控制文件的文件名,缺省为.htaccess (大多数人直接就是.htaccess,所以好多网上教程都没写这步,而我的是ht.access),可以通过更改这个文件,来改变不同目录的访问控制限制。
将ht.access改为 .htaccess 重启apache就行了。
AccessFileName .htaccess
题外:.htaccess位置问题:htaccess文件(或者"分布式配置文件")提供了针对每个目录改变配置的方法,即在一个特定的目录中放置一个包含指令的文件,其中的指令作用于此目录及其所有子目录。(每一个文件夹下都可以有个.htaccess文件)
**同时rewrite规则写入到.htaccess 配置文件的一个好处就是:**在每次新添加规则到.htaccess 文件中时,apache服务不需要重启,就直接可以生效
httpd.conf去掉注释参数如下:亲测可用 [root@VM_82_178_centos ~]# grep -vE '^#|^$' /etc/httpd/conf/httpd.conf
ServerRoot "/etc/httpd"
Include conf.modules.d/*.conf

[root@VM_82_178_centos ~]#
4.httpd.conf开启IncludeOptional参数
配置文件/etc/httpd/conf/httpd.conf中开启IncludeOptional参数,使每个vhost虚拟主机单独 写到一个配置文件中
[root@VM_82_178_centos vhost]# grep IncludeOptional /etc/httpd/conf/httpd.conf
IncludeOptional conf.d/*.conf
IncludeOptional conf/vhost/*.conf
[root@VM_82_178_centos vhost]# grep -C 10 IncludeOptional /etc/httpd/conf/httpd.conf
<IfModule mime_magic_module>
MIMEMagicFile conf/magic
</IfModule>
#EnableMMAP and EnableSendfile: On systems that support it,
EnableSendfile on
IncludeOptional conf.d/*.conf
IncludeOptional conf/vhost/*.conf
Servername 0.0.0.0:80
Listen 80
<VirtualHost *:80>
ServerAdmin webmaster@dianrui.com

ServerName 119.29.97.131
ServerAlias 119.29.97.131
</VirtualHost>
[root@VM_82_178_centos vhost]# cat /etc/httpd/conf/vhost/img.yb898.cn.conf
<VirtualHost *:80>
DocumentRoot "/data/www/images"
ServerName img.yb898.cn
ServerAlias img.yb898.cn
ErrorLog "logs/img.yb898.cn-error_log"
CustomLog "logs/img.yb898.cn-access_log" common

</VirtualHost>
centos7行httpd服务的相关的 启动命令如下:
[root@VM_82_178_centos vhost]# systemctl status httpd.service
[root@VM_82_178_centos vhost]# systemctl reload httpd.service
[root@VM_82_178_centos vhost]# systemctl start httpd.service
