Most people do not understand the knowledge points of this article, "the method of installing Nginx server program and simple environment configuration on Ubuntu", so the editor summarizes the following contents, detailed contents, clear steps, and has a certain reference value. I hope you can get something after reading this article. Let's take a look at this "Ubuntu installation of Nginx server programs and simple environment configuration method" article.

Ubuntu installs nginx from the official source

Cd ~ wget http://nginx.org/keys/nginx_signing.key sudo apt-key add nginx_signing.key sudo nano / etc/apt/sources.list # add the following two sentences: deb http://nginx.org/packages/ubuntu/ precise nginx deb-src http://nginx.org/packages/ubuntu/ precise nginx sudo apt-get update sudo apt-get install nginx

Ubuntu installs nginx from the ppa source:

Sudo add-apt-repository ppa:nginx/stable sudo apt-get update sudo apt-get install nginx

Ubuntu installs nginx from a regular source:

Sudo apt-get install nginx

Compile and install nginx

Wget http://nginx.org/packages/mainline/ubuntu/pool/nginx/n/nginx/nginx_1.5.7-1~precise_i386.deb wget http://nginx.org/download/nginx-1.5.7.tar.gztar xzf nginx-1.5.7.tar.gzcd nginx-1.5.7

(note: nginx1.5.7 is the mainline version, not the stable version)

Sudo mkdir / pngsudo chown eechen:eechen / png

I define the running user as png:png, so I need to create a new user like this:

Sudo addgroup png-systemsudo adduser png-system-disabled-login-ingroup png-no-create-home-home / nonexistent-gecos "png user"-shell / bin/false

(for commands of new users, please refer to the pre-installation script debian/preinst in the official deb package.)

The compilation parameters refer to the official deb package provided by nginx (nginx-v visible).

. / configure\-prefix=/png/nginx/1.5.7\-sbin-path=/png/nginx/1.5.7/sbin/nginx\-conf-path=/png/nginx/1.5.7/conf/nginx.conf\-error-log-path=/png/nginx/1.5.7/var/log/error.log\-http-log-path=/png/nginx/1.5.7/var/log/access.log\-pid-path=/png/ Nginx/1.5.7/var/run/nginx.pid\-lock-path=/png/nginx/1.5.7/var/run/nginx.lock\-http-client-body-temp-path=/png/nginx/1.5.7/var/cache/client_temp\-http-proxy-temp-path=/png/nginx/1.5.7/var/cache/proxy_temp\-http-fastcgi-temp-path=/png/nginx/1.5.7/var/ Cache/fastcgi_temp\-http-uwsgi-temp-path=/png/nginx/1.5.7/var/cache/uwsgi_temp\-- http-scgi-temp-path=/png/nginx/1.5.7/var/cache/scgi_temp\-- user=png\-- group=png\-- with-http_ssl_module\-- with-http_realip_module\-- with-http_addition_module\-- with-http_sub_module\-- with-http_dav_module\ -- with-http_flv_module\-- with-http_mp4_module\-- with-http_gunzip_module\-- with-http_gzip_static_module\-- with-http_random_index_module\-- with-http_secure_link_module\-- with-http_stub_status_module\-- with-mail\-- with-mail_ssl_module\-- with-file-aio\-- with-ipv6

Note: in this step, follow the error prompt to install the dependent packages, and it's time for apt to be angry, for example, these packages are installed on my system:

Sudo apt-get-y install\ build-essential\ autoconf\ libtool\ libxml2\ libxml2-dev\ openssl\ libcurl4-openssl-dev\ libbz2- 1.0\ libbz2-dev\ libjpeg-dev\ libpng12-dev\ libfreetype6\ libfreetype6-dev\ libldap-2.4-2\ libldap2-dev\ libmcrypt4\ libmcrypt-dev\ libmysqlclient-dev\ libxslt1.1\ libxslt1-dev\ libxt-dev\ libpcre3-dev

After installing these packages, there is no need to install the new version of nginx next time, and it basically meets the requirements of configure when compiling php.

All right, after the success of configure, you can compile and install:

Time make & & make install

Time is mainly used to view the time-consuming compilation.

After compiling, you can take a look at the size of this guy:

Du-sh / png/nginx/1.5.7/sbin/nginx5.5m / png/nginx/1.5.7/sbin/nginx

Summary of simple configuration of environment

Reduce the file size after nginx compilation:

Edit the source file nginx-1.5.7/auto/cc/gcc to remove the debug information (comment out):

# debug # cflags= "$cflags-g"

In this way, the size of the compiled main program is more than 700k, which is similar to the size of the deb package provided by nginx.

In addition, if some unwanted modules are removed in configure, the compiled executable file will be smaller.

Of course, I need a service script to manage nginx, and I can also use the service script etc/init.d/nginx provided in the official deb package.

I put it in / png/nginx/1.5.7/nginx and slightly modified the values defined at the beginning (lines 13 to 19):

Change path=/sbin:/usr/sbin:/bin:/usr/bindesc=nginxname=nginxconffile=/etc/nginx/nginx.confdaemon=/usr/sbin/nginxpidfile=/var/run/$name.pidscriptname=/etc/init.d/$name to path=/sbin:/usr/sbin:/bin:/usr/bindesc=nginxname=nginxconffile=/png/nginx/1.5.7/conf/nginx.confdaemon=/png/nginx/1.5.7/sbin/nginxpidfile=/png/nginx/1.5.7/var/run/$name.pidscriptname=/png/nginx/1.5.7/$name

Create a cache directory before starting, otherwise an error will be prompted:

Mkdir / png/nginx/1.5.7/var/cache

Start nginx:

Sudo / png/nginx/1.5.7/nginx start

Test page:

Curl-I `hostname`

Look at the port:

Sudo netstat-antp | grep nginx

Take a look at the memory it takes:

Htop filter nginx by f4

You can also see similar content with top:

Top-b-N1 | head-N7 & & top-b-N1 | grep nginx

Mainly look at the value of res, resident memory (resident), excluding the physical memory of swap space, the unit of kb,%mem is to take res as the reference object.

You can see that the total physical memory occupied by the two processes of nginx is less than 2 m, which is very small.

In addition, the res value in top corresponds to the rss value in ps aux:

Ps aux | head-N1 & & ps aux | grep nginx

Also, we can see that the worker process in nginx has only one thread:

Cat / proc/25047/status | grep threadsthreads: 1

25047 of them is the nginx worker process pid.

Turn nginx into a system service and boot automatically:

Sudo ln-s / png/nginx/1.5.7/nginx / etc/init.d/png-nginxsudo update-rc.d png-nginx defaults # Boot self-boot sudo update-rc.d-f png-nginx remove # do not want to boot self-boot can disable sudo service png-nginx reload # so that service can be used to manage nginx services, such as reloading configuration

Finally, nginx's main configuration file is located in / png/nginx/1.5.7/conf/nginx.conf, which is configured on demand.
