一、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。
二、在高连接并发的情况下,Nginx是Apache服务器不错的替代品。
yum -y install make zlib zlib-devel gcc-c++ libtool openssl openssl-devel
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
本人首次安装失败了,第二次成功:
[root@localhost nginx-1.19.2]# cd /usr/local/src/ [root@localhost src]# wget http://downloads.sourceforge.net/project/pcre/pcre/8.35/pcre-8.35.tar.gz
2、解压安装包:
[root@localhost src]# tar -zxvf pcre-8.35.tar.gz
3、进入安装包目录
[root@localhost src]# cd pcre-8.35
4、编译安装
[root@localhost pcre-8.35]# ./configure [root@localhost pcre-8.35]# make && make install
5、查看pcre版本
[root@localhost pcre-8.35]# pcre-config --version 8.35 [root@localhost pcre-8.35]#
1、下载 Nginx,下载地址:https://nginx.org/en/download.html
[root@localhost pcre-8.35]# cd /usr/local/src/ [root@localhost src]# wget http://nginx.org/download/nginx-1.6.2.tar.gz
2、解压安装包
[root@localhost src]# tar zxvf nginx-1.6.2.tar.gz
3、进入安装包目录
[root@localhost src]# cd nginx-1.6.2
4、编译安装
[root@localhost 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@localhost nginx-1.6.2]# make [root@localhost nginx-1.6.2]# make install
[root@localhost nginx-1.6.2]# /usr/local/webserver/nginx/sbin/nginx -v -bash: /usr/local/webserver/nginx/sbin/nginx: 没有那个文件或目录
这里我执行完安装命令后 查询nginx 版本 (我重新手动创建了文件,在执行上面的安装命令 然后 就OK了)
[root@localhost nginx-1.6.2]# /usr/local/webserver/nginx/sbin/nginx -v nginx version: nginx/1.6.2
安装完毕
1、创建 Nginx 运行使用的用户 www:
[root@localhost nginx-1.6.2]# /usr/sbin/groupadd www [root@localhost nginx-1.6.2]# /usr/sbin/useradd -g www www
2、配置nginx.conf ,将/usr/local/webserver/nginx/conf/nginx.conf替换为以下内容
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 - $remote_user [$time_local] "$request" ' '$status $body_bytes_sent "$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 $binary_remote_addr 10m; #下面是server虚拟主机的配置 server { listen 80;#监听端口 server_name localhost;#域名 index index.html index.htm index.php; root /usr/local/webserver/nginx/html;#站点目录 location ~ .*\.(php|php5)?$ { #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 ~ .*\.(js|css)?$ { expires 15d; # access_log off; } access_log off; } }
3、检查配置文件nginx.conf的正确性命令:
[root@localhost nginx-1.6.2]# /usr/local/webserver/nginx/sbin/nginx -t
1、Nginx 启动命令如下:
[root@localhost nginx-1.6.2]# /usr/local/webserver/nginx/sbin/nginx
1、从浏览器访问我们配置的站点ip:
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
