Installation of nginx_centos6.4 under Nginx

I. Process of dependence


1. Gzip module requires zlib library
2. Rewrite module requires Pcre library

3. SSL support requires OpenSSL library

Second, the CentOS Platform compilation Environment uses the following instructions, if CentOS is not installed in the network situation to execute a command can be quickly completed installation


Install Make:


Yum-y install gcc automake autoconf libtool


Make installation g++:


Yum Install gcc gcc-c++

Generally we need to first install Pcre, Zlib, the former in order to rewrite rewrite, the latter in order to gzip compression.

1. Select the source directory
Can be any directory, this article is selected/USR/LOCAL/SRC


Cd/usr/local/src
2. Installing the Pcre Library
ftp://ftp.csx.cam.ac.uk/pub/software/programming/pcre/Download the latest pcre source package, download the compile and install the Pcre package using the command below:
Cd/usr/local/src
wget ftp://ftp.csx.cam.ac.uk/pub/software/programming/pcre/pcre-8.34.tar.gz
TAR-ZXVF pcre-8.34.tar.gz
CD pcre-8.34
./configure
Make
Make install
3. Installing the Zlib Library
http://zlib.net/zlib-1.2.8.tar.gz Download the latest zlib source package and download the compile and install zlib package using the command below
Cd/usr/local/src
wget http://zlib.net/zlib-1.2.8.tar.gz
TAR-ZXVF zlib-1.2.8.tar.gz
CD zlib-1.2.8
./configure
Make
Make install
4. Install SSL (some VPS does not install SSL by default)

Cd/usr/local/src
wget http://www.openssl.org/source/openssl-1.0.1c.tar.gz
TAR-ZXVF openssl-1.0.1c.tar.gz
5. Installing Nginx


Nginx generally has two versions, the stable version and the development version, you can choose one of these two versions according to your purpose, below is the detailed steps of installing nginx into the/usr/local/nginx directory:


Cd/usr/local/src
wget http://nginx.org/download/nginx-1.4.2.tar.gz
TAR-ZXVF nginx-1.4.2.tar.gz
CD nginx-1.4.2


./configure--sbin-path=/usr/local/nginx/nginx \
--conf-path=/usr/local/nginx/nginx.conf \
--pid-path=/usr/local/nginx/nginx.pid \
--with-http_ssl_module \
--with-pcre=/usr/local/src/pcre-8.34 \
--with-zlib=/usr/local/src/zlib-1.2.8 \
--with-openssl=/usr/local/src/openssl-1.0.1c


Make
Make install



Note:--with-pcre=/usr/src/pcre-8.34 refers to the pcre-8.34 source path,--with-zlib=/usr/src/zlib-1.2.7 refers to the zlib-1.2.7 source code path.


After the installation is successful, the/usr/local/nginx directory is as follows


fastcgi.conf Koi-win Nginx.conf.default
Fastcgi.conf.default logs Scgi_params
Fastcgi_params Mime.types Scgi_params.default
Fastcgi_params.default Mime.types.default Uwsgi_params
HTML Nginx Uwsgi_params.default
Koi-utf nginx.conf Win-utf
6. Start
Ensure that the 80 port of the system is not occupied by other programs, run the/usr/local/nginx/nginx command to start Nginx,


Netstat-ano|grep 80
If the results are not found after the execution, the result is ignored this step (Ubuntu must be started with sudo, or can only be run in the foreground)


Sudo/usr/local/nginx/nginx
Open the browser to access the IP of this machine if the browser appears Welcome to nginx! Indicates that Nginx is installed and running successfully.

Nginx compilation options


Make is used to compile, it reads the instruction from the makefile, and then compiles.


The make install is used to install, and it also reads instructions from makefile and installs to the specified location.


The Configure command is used to detect the target characteristics of your installation platform. It defines all aspects of the system, including Nginx's allowed connection processing methods, such as it detects if you have CC or GCC, does not require CC or GCC, it is a shell script, and at the end of execution it creates a makefile file. The Nginx Configure command supports the following parameters:


--prefix=path defines a directory that stores files on the server, which is the installation directory of Nginx. /usr/local/nginx is used by default.
--sbin-path=path sets the path of the Nginx executable file, which defaults to Prefix/sbin/nginx.
--conf-path=path set the path to the nginx.conf configuration file. Nginx allows you to start with a different configuration file via the-C option on the command line. The default is prefix/conf/nginx.conf.
--pid-path=path sets the Nginx.pid file that will store the process number of the main process. After the installation is complete, you can change the file name at any time by using the PID directive in the nginx.conf configuration file. By default, the file name is Prefix/logs/nginx.pid.
--error-log-path=path sets the name of the primary error, warning, and diagnostic file. After the installation is complete, you can change the file name at any time, using the Error_log directive in the nginx.conf configuration file. By default, the file name is Prefix/logs/error.log.
--http-log-path=path sets the name of the log file for the HTTP server for the primary request. After the installation is complete, you can change the file name at any time, using the Access_log directive in the nginx.conf configuration file. By default, the file name is Prefix/logs/access.log.
--user=name the user who set the Nginx worker process. After the installation is complete, you can change the name of the user directive that is used in the nginx.conf configuration file at any time. The default user name is nobody.
--group=name sets the user group for the Nginx worker process. After the installation is complete, you can change the name of the user directive that is used in the nginx.conf configuration file at any time. The default is non-privileged users.
--with-select_module--without-select_module enables or disables building a module to allow the server to use the Select () method. The module will be created automatically if the platform does not support Kqueue,epoll,rtsig or/dev/poll.
--with-poll_module--without-poll_module enables or disables building a module to allow the server to use the poll () method. The module will be created automatically if the platform does not support Kqueue,epoll,rtsig or/dev/poll.
--without-http_gzip_module-does not compile the Response module for compressed HTTP servers. Compiling and running this module requires a zlib library.
--without-http_rewrite_module does not compile the rewrite module. Compiling and running this module requires PCRE library support.
--without-http_proxy_module-does not compile the Http_proxy module.
The--with-http_ssl_module-uses the HTTPS protocol module. By default, the module is not built. It is necessary to establish and run the OpenSSL library for this module.
--with-pcre=path-set the source path of the Pcre library. The source code of the Pcre Library (version 4.4-8.30) needs to be downloaded and decompressed from the Pcre website. The rest of the work is nginx./configure and make to complete. Regular expressions are used in the location directive and in the Ngx_http_rewrite_module module.
The--with-pcre-jit-compilation Pcre contains "Just-in-time compilation" (1.1.12, Pcre_jit instructions).
--with-zlib=path-sets the source path of the zlib library. To download and unzip from zlib (version 1.1.3-1.2.5). The rest of the work is nginx./configure and make complete. The Ngx_http_gzip_module module requires the use of zlib.
--with-cc-opt=parameters-set additional parameters will be added to the cflags variable. For example, when you use the Pcre library on FreeBSD, you need to use the following:--with-cc-opt= "-i/usr/local/include: If you need to increase the number of files supported by select (),--with-cc-opt="-D fd_ setsize=2048 ".
--with-ld-opt=parameters-sets the additional parameters that will be used during the link. For example, when using the system's Pcre library under FreeBSD, you should specify:--with-ld-opt= "-l/usr/local/lib".
Typical instances (below in order to demonstrate the need to write on multiple lines, the content needs to be on the same line at execution)


./configure
--sbin-path=/usr/local/nginx/
--conf-path=/usr/local/nginx/nginx.conf
--pid-path=/usr/local/nginx/nginx.pid
--with-http_ssl_module
--with-pcre=. /pcre-4.4
--with-zlib=. /zlib-1.1.3


More Installation Configurations
./configure--prefix=/usr/local/nginx
--with-openssl=/usr/include (SSL enabled)
--with-pcre=/usr/include/pcre/(enable regular expression)
--with-http_stub_status_module (Install a program that can view nginx status)
--with-http_memcached_module (enable Memcache cache)
--with-http_rewrite_module (enable support for URL rewriting)
