Nginx 安装配置

Nginx(“engine x”)是一款是由俄罗斯的程序设计师Igor Sysoev所开发高性能的 Web和 反向代理 服务器，也是一个 IMAP/POP3/SMTP 代理服务器。

在高连接并发的情况下，Nginx是Apache服务器不错的替代品。

Nginx 安装

系统平台：CentOS release 7.6 (Final) 64位。

一、安装编译工具及库文件

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

二、第一要安装 PCRE

PCRE 作用是让 Nginx 支持 Rewrite 功能。

1、下载 PCRE 安装包，下载地址：
http://downloads.sourceforge.net/project/pcre/pcre/8.35/pcre-8.35.tar.gz

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

2、解压安装包:

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

3、进入安装包目录

[root@bogon src]# cd pcre-8.35

4、编译安装

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

5、查看pcre版本

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

安装 Nginx

1、下载 Nginx，下载地址：
https://nginx.org/en/download.html

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

2、解压安装包

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

3、进入安装包目录

[root@bogon src]# cd nginx-1.6.2

4、编译安装

[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

其他编译选项，可以选加

–error-log-path=/var/log/nginx/error.log

–http-log-path=/var/log/nginx/access.log

–pid-path=/run/nginx.pid

–lock-path=/run/nginx.lock

–user=nginx

–group=nginx

–with-file-aio

–with-http_auth_request_module

–with-http_ssl_module

–with-http_v2_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-pcre

–with-stream=dynamic

–with-stream_ssl_module

–with-ipv6

–with-http_stub_status_module

[root@bogon nginx-1.6.2]# make[root@bogon nginx-1.6.2]# make install

5、查看nginx版本

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

到此，nginx安装完成。

Nginx 配置

创建 Nginx 运行使用的用户 www：

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

配置nginx.conf ，将
/usr/local/webserver/nginx/conf/nginx.conf替换为以下内容

[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

pid /usr/local/webserver/nginx/nginx.pid;#Specifies the value for maximum file descriptors that can be opened by this process.

}

}

检查配置文件nginx.conf的正确性命令：

[root@bogon conf]# /usr/local/webserver/nginx/sbin/nginx -t

启动 Nginx

Nginx 启动命令如下：

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

访问站点

从浏览器访问我们配置的站点ip：

Nginx 其他命令

以下包含了 Nginx 常用的几个命令：

/usr/local/webserver/nginx/sbin/nginx -s reload # 重新载入配置文件
/usr/local/webserver/nginx/sbin/nginx -s reopen # 重启
Nginx/usr/local/webserver/nginx/sbin/nginx -s stop # 停止 Nginx
