Note: the server environment is centos

I. brief introduction

Tengine is a web server project initiated by Taobao. On the basis of nginx, it adds a lot of advanced functions and features to meet the needs of high-volume websites. The performance and stability of tengine have been well tested in large websites such as Taobao and Tmall Mall. Its ultimate goal is to create an efficient, stable, secure and easy-to-use web platform.

Since December 2011, tengine has become an open source project, and the tengine team is actively developing and maintaining it. The core members of the tengine team come from Internet companies such as Taobao and Sogou. Tengine is the result of community cooperation, and we welcome all of you to participate and contribute to it.

2. Characteristics

Inherits all the features of nginx-1.2.9 and is 100% compatible with nginx configuration

Dynamic module loading (dso) support. Adding a module eliminates the need to recompile the entire tengine

Input filter mechanism support. It is more convenient to write web application firewall by using this mechanism.

Dynamic scripting language lua support. The extension is very efficient and simple.

Support for pipe and syslog (local and remote) logs and log sampling

An access request that combines multiple css and javascript files into a single request

More powerful load balancing capabilities, including consistency hash module and session persistence module. It can also actively check the health of the back-end server and automatically go online and offline according to the server status.

Automatically set the number of processes and binding cpu affinity according to the number of cpu

Monitor the load and resource consumption of the system to protect the system

Display error messages that are more friendly to operators, making it easy to locate error machines

More powerful anti-attack (access speed limit) module

More convenient command line parameters, such as listing compiled modules, supported instructions, etc.

You can set the expiration time according to the type of access file

III. Installation

1.yum installation

Yum installation is relatively simple, after configuring the source, you can directly yum install.

① configure a third-party yum source (there is no nginx package in the default source for centos)

The copy code is as follows:

Yum install wget # install download tool wget

Wget http://www.atomicorp.com/installers/atomic # download atomic yum feed

Sh. / atomic # installation

Yum check-update # updates the yum package

② installation configuration

The copy code is as follows:

Yum install nginx # install nginx, according to the prompts, enter y to install successfully

Service nginx start # Startup

Chkconfig nginx on # is set to boot

/ etc/init.d/nginx restart # restart

Rm-rf / usr/share/nginx/html/* # remove the ngin default test page

two。 Source code compilation and installation

The source code installation is a little more complicated, and there are some related dependent packages that need to be compiled separately

The source code installation can choose either the original nginx or the modified tengine on Taobao. It is recommended that tengin,tengine is fully compatible with nginx and adds many new features, which are suitable for increasingly complex business expansion.

Tengine official website: http://tengine.taobao.org/

① first installs pcre to support pseudo-static of nginx

The copy code is as follows:

# cd / usr/local/src

# wget ftp://ftp.csx.cam.ac.uk/pub/software/programming/pcre/pcre-8.21.tar.gz

# tar zxvf pcre-8.21.tar.gz

# mkdir / usr/local/pcre # create installation directory

# cd pcre-8.21

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

# make

# make install

② install tengine

The copy code is as follows:

# cd / usr/local/src

# wget http://tengine.taobao.org/download/tengine-1.4.2.tar.gz

# tar zxvf tengine-1.4.2.tar.gz

# cd tengine

#. / configure-prefix=/usr/local/nginx-with-http_stub_status_module-with-pcre=/usr/local/src/pcre-8.21

# make

# make install

# / usr/local/nginx/sbin/nginx # start nginx

# chown nobody.nobody-r / usr/local/nginx/html

# chmod 700-r / usr/local/nginx/html

Note:-- with-pcre=/usr/local/src/pcre-8.21 points to the path to which the source package is decompressed, not the path to be installed, otherwise an error will be reported.

③ setting tengine boot

The copy code is as follows:

# vi / etc/rc.d/init.d/nginx # Edit startup file to add the following

#! / bin/bash

# tengine startup script# 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 "tengine 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 # Grant file execution permissions

# chkconfig nginx on # set boot

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

At this point, the nginx installation is complete. Here's why you use Taobao's tengine:

1. Inherits all the features of nginx and is 100% compatible with nginx configuration

two。 Dynamic module loading (dso) support. Adding a module eliminates the need to recompile the entire tengine

3. Input filter mechanism support. It is more convenient to write web application firewall by using this mechanism.

4. Dynamic scripting language lua support. The extension is very efficient and simple.

5. Support for pipe and syslog (local and remote) logs and log sampling

6. An access request that combines multiple css and javascript files into a single request

IV. Success page

After installing and launching tengine, the browser enters the ip address and the following figure shows that the installation is successful.

V. matters needing attention

1.-with-openssl=/usr/local/src/openssl-1.0.1e may make errors in this step. Note:-with-openssl=/usr/local/src/openssl-1.0.1e points to the path where the source code package is decompressed, not the path of installation, otherwise it will report an error, download and decompress the source code package, as follows:

Cd / usr/local/src

Wget http://www.openssl.org/source/openssl-1.0.1e.tar.gz

Tar zxvf openssl-1.0.1e

Then re-perform the tengine installation.
