This article editor for you detailed introduction of "CentOS how to install Tengine", the content is detailed, the steps are clear, the details are handled properly, I hope this "CentOS how to install Tengine" article can help you solve your doubts, following the editor's ideas slowly in-depth, let's learn new knowledge together.

1. Install the necessary compilation environment.

Because the tengine installation requires self-compilation using the source code, you need to install the necessary compilation tools before installation:

The copy code is as follows:

# yum update

# yum install gcc gcc-c++ autoconf automake

2. Install the required components

A 、 pcre

Pcre (perl compatible regular expressions) is a perl library, including a perl-compatible library of regular expressions. Nginx rewrite depends on the pcre library, so be sure to install pcre before installing tengine. The latest version of pcre is available on the official website (). The specific installation process is as follows:

The copy code is as follows:

Cd / usr/local/src

Wget

Tar zxvf pcre-8.36.tar.gz

Cd pcre-8.36

. / configure-- prefix=/usr/local/pcre

Make & & make install

The copy code is as follows:

The installation of source code generally consists of three steps: configure, make, and make install.

Configure is an executable script that has many options. Use the command. / configure-help to output a detailed list of options under the source path to be installed. The-prefix option is the path to configure the installation. If this option is not configured, the executable file is placed at / usr/local/ bin by default, the library file is placed at / usr/local/lib by default, the configuration file is placed at / usr/local/etc by default, and other resource files are placed at / usr/local/ share, which is messy.

If you configure-prefix, such as:. / configure-prefix=/usr/local/test, you can put all resource files in the path of / usr/local/test without clutter.

Another benefit of using the-prefix option is to uninstall or migrate the software. When an installed software is no longer needed, simply delete the installation directory and uninstall the software cleanly; migrate the software simply by copying the entire directory to another machine (the same operating system). Of course, to uninstall the program, you can also use make uninstall once in the original make directory, but only if the make file has specified uninstall.

B 、 openssl

Openssl is a powerful secure socket layer cipher library that includes major cryptographic algorithms, commonly used key and certificate encapsulation management functions, and ssl protocols, and provides rich applications for testing or other purposes. The main purpose of installing openssl () is to enable tengine to support access requests from https. Whether to install or not depends on the demand.

The copy code is as follows:

Cd / usr/local/src

Wget

Tar zxvf openssl-1.0.2.tar.gz

Cd openssl-1.0.2.tar.gz

. / configure-- prefix=/usr/local/openssl

Make & & make install

C 、 zlib

Zlib is a library that provides data compression, and zlib () is needed when tengine wants to enable gzip compression.

The copy code is as follows:

Cd / usr/local/src

Wget

Tar zxvf zlib-1.2.8.tar.gz

Cd zlib-1.2.8.tar.gz

. / configure-- prefix=/usr/local/zlib

Make & & make install

D 、 jemalloc

Jemalloc () is a better memory management tool, and using jemalloc can better optimize the memory management of tengine.

The copy code is as follows:

Cd / usr/local/src

Wget

Tar jxvf jemalloc-3.6.0.tar.bz2

Cd jemalloc-3.6.0.tar.bz2

. / configure-- prefix=/usr/local/jemalloc

Make & & make install

3. Install tengine

Tegine can be installed after the main core components are installed, and the latest version of tegine is available on the official website ().

One more thing you need to do before compiling and installing is to add a dedicated user to execute tengine. Of course you can also use root (not recommended).

The copy code is as follows:

Groupadd www-data

Useradd-s / sbin/nologin-g www-data www-data

The next step is to install:

The copy code is as follows:

Cd / usr/local/src

Wget

Tar-zxvf tengine-2.1.0.tar.gz

Cd tengine-2.1.0

. / configure-- prefix=/usr/local/nginx\

-- user=www-data\

-- group=www-data\

-- with-pcre=/usr/local/src/pcre-8.36\

-- with-openssl=/usr/local/src/openssl-1.0.2\

-- with-jemalloc=/usr/local/src/jemalloc-3.6.0\

-- with-http_gzip_static_module\

-- with-http_realip_module\

-- with-http_stub_status_module\

-- with-http_concat_module\

-- with-zlib=/usr/local/src/zlib-1.2.8

Make & & make install

Note that when configuring-with-pcre,-with-openssl,-with-jemalloc,-with-zlib, the path is the path of the source file.

4. Configure tengine and set tengine to start automatically

The copy code is as follows:

# vim / etc/rc.d/init.d/nginx

# Edit startup file to add the following

#! / bin/bash

# nginx startup script for the nginx http server

# it is v.0.0.2 version.

# chkconfig:-85 15

# description: nginx is a high-performance web and proxy server.

# it has a lot of features, but it's not for everyone.

# processname: nginx

# pidfile: / var/run/nginx.pid

# config: / usr/local/nginx/conf/nginx.conf

Nginxd=/usr/local/nginx/sbin/nginx

Nginx_config=/usr/local/nginx/conf/nginx.conf

Nginx_pid=/usr/local/nginx/logs/nginx.pid

Retval=0

Prog= "nginx"

# source function library.

. / etc/rc.d/init.d/functions

# source networking configuration.

. / etc/sysconfig/network

# check that networking is up.

[${networking} = "no"] & & exit 0

[- x $nginxd] | | exit 0

# start nginx daemons functions.

Start () {

If [- e $nginx_pid]; then

Echo "nginx already running...."

Exit 1

Fi

Echo-n $"starting $prog:"

Daemon $nginxd-c ${nginx_config}

Retval=$?

Echo

[$retval = 0] & & touch / var/lock/subsys/nginx

Return $retval

}

# stop nginx daemons functions.

Stop () {

Echo-n $"stopping $prog:"

Killproc $nginxd

Retval=$?

Echo

[$retval = 0] & & rm-f / var/lock/subsys/nginx / usr/local/nginx/logs/nginx.pid

}

Reload () {

Echo-n $"reloading $prog:"

# kill-hup `cat ${nginx_pid} `

Killproc $nginxd-hup

Retval=$?

Echo

}

# see how we were called.

Case "$1" in

Start)

Start

Stop)

Stop

Reload)

Reload

Restart)

Stop

Start

Status)

Status $prog

Retval=$?

*)

Echo $"usage: $prog {start | stop | restart | reload | status | help}"

Exit 1

Esac

Exit $retval

Save exit

The copy code is as follows:

Chmod 775 / etc/rc.d/init.d/nginx # gives file execution permissions

Chkconfig nginx on # set boot up

Service nginx restart # start the service
