SOURCE Package Management
1. Get the source package path
Official website to get the latest packages
Apache:www.apache.org
Nginx:www.nginx.org
Tengine:tengine.taobao.org
2. Practical Cases
Deploying the Tengine/nginx Server/web server
1. Download the source package, prepare the package
2. Prepare the compilation environment such as compiler GCC, make
# yum-y Install gcc make zlib-devel pcre pcre-devel openssl-devel
(Pcre: Supports regular expressions, address rewriting rewrite)

3. Unzip
# Useradd www
# tar XVF tengine-2.2.0.tar.gz
# CD tengine-2.2.0
4. Configuration
./configure \
--USER=WWW \
--GROUP=WWW \
--prefix=/usr/local/nginx \
--with-http_stub_status_module \
--with-http_sub_module \
--with-http_ssl_module \
--with-pcre
5. Compiling
# make
6. Installation
# make Install

7 Start Test
#/usr/local/nginx/sbin/nginx//start Nginx server
# Systemctl Stop Firewalld
See the Web page that indicates the deployment was successful.
