apache开启gzip

如何在Apache2中设置Gzip

Gzip是一种用于压缩数据的文件格式，可以有效地减少传输数据的大小，从而提高网站的加载速度，在Apache2中设置Gzip,需要进行以下几个步骤：

1、安装Gzip模块

在Debian/Ubuntu系统中，使用以下命令安装Gzip模块：

sudo apt-get install libapache2-mod-gzip

在CentOS/RHEL系统中，使用以下命令安装Gzip模块：

sudo yum install httpd-mod-gzip

2、启用Gzip模块

在Apache2的配置文件(通常位于/etc/apache2/apache2.conf或/etc/httpd/httpd.conf)中，找到以下行：

LoadModule accel_exp "libexec/apache2/mod_accelerator.so"
LoadModule filter_module "libexec/apache2/mod_filter.so"
LoadModule rewrite_module "libexec/apache2/mod_rewrite.so"
LoadModule vhost_alias_module "libexec/apache2/mod_vhost_alias.so"
LoadModule vhost_ssl_module "libexec/apache2/mod_vhost_ssl.so"
LoadModule proxy_module "libexec/apache2/mod_proxy.so"
LoadModule proxy_uwsgi_module "libexec/apache2/mod_proxy_uwsgi.so"
LoadModule uwsgi_module "libexec/apache2/mod_uwsgi.so"
LoadModule scgi_module "libexec/apache2/mod_scgi.so"
LoadModule fastcgi_module "libexec/apache2/mod_fastcgi.so"
LoadModule action_module "libexec/apache2/mod_action.so"
LoadModule storage_sync_module "libexec/apache2/mod_storage_sync.so"
LoadModule aliases_module "libexec/apache2/mod_aliases.so"
LoadModule authz_host_module "libexec/apache2/mod_authz_host.so"
LoadModule status_module "libexec/apache2/mod_status.so"
LoadModule request_module "libexec/apache2/mod_request.so"
LoadModule log_config_module "libexec/apache2/mod_log_config.so"
LoadModule logio_module "libexec/apache2/mod_logio.so"
LoadModule include_module "libexec/apache2/mod_include.so"
LoadModule envvars_module "libexec/apache2/mod_envvars.so"
LoadModule setenvif_module "libexec/apache2/mod_setenvif.so"
LoadModule headers_module "libexec/apache2/mod_headers.so"
LoadModule deflate_module "libexec/apache2/mod_deflate.so"

在这些行下面添加一行，启用Gzip模块：

SetEnvIfNoCase Request_URI .(?i:gz|gzip)$ no-gzip dont-vary

3、配置Gzip压缩级别和缓存策略

打开Apache2的配置文件(通常位于/etc/apache2/apache2.conf或/etc/httpd/httpd.conf),在文件末尾添加以下内容：

<IfModule mod_deflate.c>
  AddOutputFilterByType DEFLATE text/plain text/* application/javascript application/x-javascript text/xml application/* xml application/*+xml text/* html;q=0.9 image/*;q=0.8 image/*;q=0.5 text/*;q=0.5 video/*;q=0.5 audio/*;q=0.4 font/*;q=0.4 style/*;q=0.4 image/*;q=0.3 connection /*;q=0.1 default type text/html image/png imagejpeg imagegif imagesvg application/json application/*+json text/*+json application/*+xml application/*+xml text/*+xml application/*+x-javascript;q=0.9 text/*+x-javascript;q=0.8 text/*+xml;q=0.8 text/*+xml;q=0.7 application/*+xml;q=0.6 application/*+xml;q=0.5 x-javascript*; q=0.5 x-javascript*/\*;q=0\.5 image/*;\* q=0\.5 image/*/\*;q=0\.5 video/*;\* q=0\.5 video/*/*;q=0\.5 audio/*;\* q=0.5 audio/\*;q=0\.5 css */p a {  ADD YOUR LOGIC HERE }
