生活不是林黛玉，不会因为忧伤而风情万种。

 

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

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、首先要安装 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

[[email protected] src]# wget http://downloads.sourceforge.net/project/pcre/pcre/8.35/pcre-8.35.tar.gz

2、解压安装包:

[[email protected] src]# tar zxvf pcre-8.35.tar.gz

3、进入安装包目录

[[email protected] src]# cd pcre-8.35

4、编译安装 

[[email protected] pcre-8.35]# ./configure
[[email protected] pcre-8.35]# make && make install

5、查看pcre版本

[[email protected] pcre-8.35]# pcre-config --version

 

三、安装 Nginx

1、下载 Nginx，下载地址：http://nginx.org/download/nginx-1.6.2.tar.gz

[[email protected] src]# wget http://nginx.org/download/nginx-1.6.2.tar.gz

2、解压安装包

[[email protected] src]# tar zxvf nginx-1.6.2.tar.gz

3、进入安装包目录

[[email protected] src]# cd nginx-1.6.2

4、编译安装

[[email protected] 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
[[email protected] nginx-1.6.2]# make
[[email protected] nginx-1.6.2]# make install

5、查看nginx版本

[[email protected] nginx-1.6.2]# /usr/local/webserver/nginx/sbin/nginx -v

到此，nginx安装完成。

 

四、Nginx 配置

创建 Nginx 运行使用的用户 www：

[[email protected] conf]# /usr/sbin/groupadd www 
[[email protected] 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

[[email protected] 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.
worker_rlimit_nofile 65535;
events
{
use epoll;
worker_connections 65535;
}
http
{
include mime.types;
default_type application/octet-stream;
log_format main '$remote_addr - $remote_user [$remoteu​ser[time_local] “KaTeX parse error: Expected 'EOF', got '#' at position 37: … style="color: #̲800000">'</span…status $body_bytes_sent &quot;$bodyb​ytess​ent"http_referer” ’
‘"$http_user_agent" $http_x_forwarded_for’;

#charset gb2312;

server_names_hash_bucket_size 128;
client_header_buffer_size 32k;
large_client_header_buffers 4 32k;
client_max_body_size 8m;

sendfile on;
tcp_nopush on;
keepalive_timeout 60;
tcp_nodelay on;
fastcgi_connect_timeout 300;
fastcgi_send_timeout 300;
fastcgi_read_timeout 300;
fastcgi_buffer_size 64k;
fastcgi_buffers 4 64k;
fastcgi_busy_buffers_size 128k;
fastcgi_temp_file_write_size 128k;
gzip on;
gzip_min_length 1k;
gzip_buffers 4 16k;
gzip_http_version 1.0;
gzip_comp_level 2;
gzip_types text/plain application/x-javascript text/css application/xml;
gzip_vary on;

#limit_zone crawler KaTeX parse error: Expected 'EOF', got '#' at position 26: …ote_addr 10m; #̲下面是server虚拟主机的配…
{
#fastcgi_pass unix:/tmp/php-cgi.sock;
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
include fastcgi.conf;
}
location ~ .*.(gif|jpg|jpeg|png|bmp|swf|ico)$
{
expires 30d;

access_log off;

}
location </span>~ .*\.(js|css)?<span style="color: #000000">$
{
  expires 15d;

access_log off;

}
access_log off;

}

}

检查配置文件ngnix.conf的正确性命令：

[[email protected] conf]# /usr/local/webserver/nginx/sbin/nginx -t

五、启动 Nginx

Nginx 启动命令如下：

[[email protected] conf]# /usr/local/webserver/nginx/sbin/nginx

六、访问站点

从浏览器访问我们配置的站点ip：

七、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

Nginx的启动、停止与重启操作

[[email protected] sbin]# /usr/local/nginx/sbin/nginx -c /usr/local/nginx/conf/nginx.conf

[[email protected] ~]# ps -ef|grep nginx

[[email protected] ~]# kill -QUIT 2072

[[email protected] ~]# ps -ef|grep nginx

[[email protected] ~]# kill -TERM 2132

或 [[email protected] ~]# kill -INT 2132

[[email protected]er ~]# pkill -9 nginx
