CentOS6.5 install and configure Tengine

CentOS6.5 install and configure Tengine
1. Install pcre:
Copy code

Cd/usr/local/src
Wget http://downloads.sourceforge.net/project/pcre/pcre/8.34/pcre-8.34.tar.gz

Tar zxvf pcre-8.34.tar.gz
Cd pcre-8.34
./Configure -- prefix =/usr/local/pcre
Make
Make install

Copy code
Ii. Download The proxy_cache plug-in

Cd/usr/local/src

Wget http://labs.frickle.com/files/ngx_cache_purge-2.1.tar.gz

Tar zxvf ngx_cache_purge-2.1.tar.gz



3. Install tengine
Press Ctrl + C to copy the code
Press Ctrl + C to copy the code

/Usr/local/nginx/sbin/nginx # Start nginx
Chown nobody. nobody-R/usr/local/nginx/html
Chmod 700-R/usr/local/nginx/html

If there is a compilation problem, check whether the cause is as follows:

./Configure: error: the http ssl module requires OpenSSL library
Cause: openssl library is required to install the http_ssl_module.
Solution: yum install openssl-devel
./Configure: error: the HTTP rewrite module requires the PCRE library.
Cause: to install the http_rewrite_module, you must first install the PCRE development kit.
Solution: yum install pcre-devel



Note:

-- With-pcre =/usr/local/src/pcre-8.21 points to the source package unzipping path, rather than the installation path, otherwise an error is reported.

-- Add-module =/usr/local/src/ngx_cache_purge-2.1 is the plug-in module that loads the cache
4. Set Tengine to start

4. Configure Tengine
Back up the nginx initial configuration file. We need to recreate the configuration file.

Mv/usr/local/nginx/conf/nginx. conf/usr/local/nginx/conf/nginx. conf. bak

Create nginx user www

Groupadd www
Useradd-g www

Edit the main configuration file:

Vi/usr/local/nginx/conf/nginx. conf

The content is as follows:
Copy code

Edit the proxy configuration file:

Edit the host configuration file:

Vi/usr/local/nginx/conf/mysvrhost. conf

Edit the compressed configuration file:

The content is as follows:
Copy code
