Nginx的安装和配置

1.安装说明：

系统环境：Ubuntu 14.04.3 LTS

软件：nginx-1.8.0.tar.gz

安装位置：/opt/nginx

 

2.安装

需要用到的安装包：

openssl-fips-2.0.10.tar.gz

zlib-1.2.8.tar.gz

pcre-8.37.tar.gz

nginx-1.8.0.tar.gz

安装顺序依次为:openssl、zlib、pcre, 然后安装Nginx包

 

2.1安装openssl-fips-2.0.2.tar.gz

tar –zxvf openssl-fips-2.0.10.tar.gz

cd openssl-fips-2.0.10

./config

make

make install

2.2 安装zlib-1.2.8.tar.gz

tar –zxvf zlib-1.2.8.tar.gz

cd zlib-1.2.8

./configure

make

make install

2.3安装pcre-8.37.tar.gz (需安装编译c++环境: apt-get install build-essential)

在安装pcre-8.37.tar.gz之前需要安装c++编译环境，否则在执行./configure时会报错。

apt-get install build-essential

 

tar –zxvf pcre-8.37.tar.gz

cd pcre-8.37

./configure

make

make install

2.4安装nginx-1.8.0.tar.gz

tar -zxvf nginx-1.8.0.tar.gz

cd nginx-1.8.0

./configure --with-pcre=../pcre-8.37 --with-zlib=../zlib-1.2.8 --with-openssl=../openssl-fips-2.0.10

make

make install

至此Nginx的安装完成!

检测nginx是否安装成功

cd /usr/local/nginx/sbin

./nginx –t

出现如下所示提示,表示安装成功

root@wcyong :/usr/local/nginx/sbin# ./nginx -t

nginx: the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok

nginx: configuration file /usr/local/nginx/conf/nginx.conf test is successful

启动nginx

./ngixn

查看端口：

netstat -tnlp  | grep nginx

root@wcyong :/usr/local/nginx/sbin# netstat -tnlp | grep nginx

tcp        0      0 0.0.0.0:80              0.0.0.0:*               LISTEN      2957/nginx

并且通过浏览器访问

3.nginx负载均衡配置

打开 /usr/local/nginx/conf/nginx.conf 配置文件，做如下配置即可：

worker_processes  1;
 
#error_log  logs/error.log;
#error_log  logs/error.log  notice;
