Nginx【第一篇】安装

Nginx【第一篇】安装

一、简介

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。

二、准备

1、环境

系统平台:Red Hat Enterprise Linux Server release 7.3 (Maipo)

内核版本:3.10.0-514.el7.x86_64

2、安装编译工具和库文件

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

3、安装pcre

PCRE 作用是让 Ngnix 支持 Rewrite 功能。

查看是否安装pcre

# pcre-config --version

Nginx【第一篇】安装

上述表明已安装。

若未安装,参照以下步骤:

1)下载

地址:https://sourceforge.net/projects/pcre/files/pcre/

2)解压安装包:
# tar zxvf pcre-8.35.tar.gz

3)编译安装
# cd pcre-8.35

# ./configure

# make && make install

三、安装

1、下载 nginx 安装包

http://nginx.org/download/

2、解压

# tar zxvf nginx-1.10.2.tar.gz

3、编译

# ./configure --prefix=/usr/local/nginx --with-http_stub_status_module --with-http_ssl_module --with-pcre

4、安装

# make

# make install

5、测试

查看nginx版本

# /usr/local/nginx/sbin/nginx -v

显示版本信息,证明已安装成功

四、配置

1、创建用户

创建 Nginx 运行使用的用户 ruready:
# /usr/sbin/groupadd ruready
# /usr/sbin/useradd -g ruready ruready

2、配置nginx.conf

# vi /usr/local/nginx/conf/nginx.conf

user  ruready ruready;
worker_processes 2; error_log /usr/local/nginx/logs/error.log crit; # 日志位置和日志级别
pid /usr/local/nginx/logs/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 - $remote_user [$time_local] "$request" '
'$status $body_bytes_sent "$http_referer" '
'"$http_user_agent" "$http_x_forwarded_for"'; access_log /usr/local/nginx/logs/access.log main; sendfile on;
tcp_nopush on; keepalive_timeout 60; 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; # 下面是server虚拟主机的配置
server {
listen 80;#监听端口
server_name localhost;#域名 charset utf-8; access_log /usr/local/nginx/logs/host.access.log main; location / {
root html;
index index.html index.htm;
} error_page 404 /404.html; # redirect server error pages to the static page /50x.html error_page 500 502 503 504 /50x.html;
location = /50x.html {
root html;
} # proxy the PHP scripts to Apache listening on 127.0.0.1:80 #location ~ \.php$ {
# proxy_pass http://127.0.0.1;
#} # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000 location ~ \.php$ {
root html;
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME /scripts$fastcgi_script_name;
include fastcgi_params;
} # deny access to .htaccess files, if Apache's document root
# concurs with nginx's one
#
#location ~ /\.ht {
# deny all;
#}
} # another virtual host using mix of IP-, name-, and port-based configuration
#
#server {
# listen 8000;
# listen somename:8080;
# server_name somename alias another.alias; # location / {
# root html;
# index index.html index.htm;
# }
#} # HTTPS server
#
#server {
# listen 443 ssl;
# server_name localhost; # ssl_certificate cert.pem;
# ssl_certificate_key cert.key; # ssl_session_cache shared:SSL:1m;
# ssl_session_timeout 5m; # ssl_ciphers HIGH:!aNULL:!MD5;
# ssl_prefer_server_ciphers on; # location / {
# root html;
# index index.html index.htm;
# }
#} }

3、检查配置文件ngnix.conf的正确性

# /usr/local/nginx/sbin/nginx -t

五、启动

1、启动命令

# /usr/local/nginx/sbin/nginx

2、访问测试

3、可以通过 links命令测试

links 127.0.0.1:8080

六、常用命令

/usr/local/nginx/sbin/nginx -c /usr/local/nginx/sbin/nginx/nginx.conf # 加载指定配置文件启动

/usr/local/nginx/sbin/nginx -s reload # 重新载入配置文件

/usr/local/nginx/sbin/nginx -s reopen # 重启 Nginx

/usr/local/nginx/sbin/nginx -s stop # 停止 Nginx

七、其他

1、设置开机启动

echo "/usr/local/nginx/sbin/nginx -c /usr/local/nginx/conf/nginx.conf" >> /etc/rc.local

2、添加到 service 服务

touch /etc/init.d/nginx

chmod 755 nginx   //修改脚本文件nginx的权限

chkconfig --add nginx  //将脚本文件加入chkconfig中

chkconfig --level 35 nginx on  //设置nginx开机在3和5级别自动启动

nginx 文件内容如下:

 #!/bin/sh
#
# nginx - this script starts and stops the nginx daemon
#
# chkconfig: -
# description: Nginx is an HTTP(S) server, HTTP(S) reverse \
# proxy and IMAP/POP3 proxy server
