nginx installation example code analysis

nginx installation

System platform: centos release 6.6 (final) 64-bit.

1. Install compilation tools and library files

yum -y install make zlib zlib-devel gcc-c++ libtool openssl openssl-devel

2. First install pcre

pcre is used to enable ngnix to support the rewrite function.

1. Download the pcre installation package, download address:

[root@bogon src]# wget http://downloads.sourceforge.net/project/pcre/pcre/8.35/pcre-8.35.tar.gz

##2. Unzip the installation package:

[root@bogon src]# tar zxvf pcre-8.35.tar.gz

3. Enter the installation package directory

[root@bogon src]# cd pcre-8.35

4. Compile and install

[root@bogon pcre-8.35]# ./configure
[root@bogon pcre-8.35]# make && make install

5. Check the pcre version

[root@bogon pcre-8.35]# pcre-config --version

Install nginx

1. Download nginx, download address:

[root@bogon src]# wget http://nginx.org/download/nginx-1.6.2.tar.gz

2. Unzip and install Package

[root@bogon src]# tar zxvf nginx-1.6.2.tar.gz

3. Enter the installation package directory

[root@bogon src]# cd nginx-1.6.2

4. Compile and install

[root@bogon nginx-1.6.2]# ./configure --prefix=/usr/local/webserver/nginx --with-http_stub_status_module --with-http_ssl_module --with-pcre=/usr/local/src/pcre-8.35
[root@bogon nginx-1.6.2]# make
[root@bogon nginx-1.6.2]# make install

5. Check nginx version

[root@bogon nginx-1.6.2]# /usr/local/webserver/nginx/sbin/nginx -v

At this point, nginx installation is complete.

nginx configuration

Create the user www for nginx to run:

[root@bogon conf]# /usr/sbin/groupadd www 
[root@bogon conf]# /usr/sbin/useradd -g www www

Configure nginx.conf, and Replace /usr/local/webserver/nginx/conf/nginx.conf with the following content

Note that the following configurations should be added as appropriate and do not copy them all. It is easy for novices to report errors

[root@bogon conf]# cat /usr/local/webserver/nginx/conf/nginx.conf

user www www;
worker_processes 2; #设置值和cpu核心数一致
error_log /usr/local/webserver/nginx/logs/nginx_error.log crit; #日志位置和日志级别
