1、Nginx特点
#是一个支持高并发、高性能、轻量级的http服务器 #可以作为邮件代理服务器 #可以作为反向代理服务器 #支持负载均衡,可以作为负载均衡服务器 高性能、高并发、轻量级、占用内存小、模块化
2、系统环境
[root@wrx ~]# uname -sir Linux 2.6.32-696.el6.x86_64 x86_64
3、搭建反向代理服务器
3.1、基本环境搭建
新建三个虚拟机,系统都安装了CentOS6.9 64位(系统安装及基本实验环境搭建略过)。将192.168.1.171作为反向代理服务器,其余两台作为web服务器。搭建结构如上图所示。
3.2、web服务器安装
在192.168.1.118和192.168.1.169上安装Apache并开启相应服务,然后在web根目录下新建index.html文件,文件内容为其ip地址。
[root@wrx ~]# yum install httpd -y [root@wrx ~]# service httpd start
3.3、安装Nginx
在192.167.1.171上安装nginx
#安装gcc [root@wrx ~]# yum install gcc-c++ -y #安装nginx需要的依赖库 [root@wrx ~]# yum install zlib-devel openssl-devel pcre-devel -y #查询是否有安装过nginx [root@wrx ~]# rpm -qa | grep nginx #或 [root@wrx ~]# whereis nginx #安装nginx [root@wrx ~]# yum install nginx -y #查看是否安装 [root@wrx ~]# rpm -qa | grep nginx nginx-mod-mail-1.10.2-1.el6.x86_64 nginx-mod-stream-1.10.2-1.el6.x86_64 nginx-mod-http-perl-1.10.2-1.el6.x86_64 nginx-mod-http-geoip-1.10.2-1.el6.x86_64 nginx-filesystem-1.10.2-1.el6.noarch nginx-mod-http-image-filter-1.10.2-1.el6.x86_64 nginx-mod-http-xslt-filter-1.10.2-1.el6.x86_64 nginx-1.10.2-1.el6.x86_64 nginx-all-modules-1.10.2-1.el6.noarch #或 [root@wrx ~]# whereis nginx #查看nginx版本 [root@wrx nginx]# nginx -v nginx version: nginx/1.10.2 #修改nginx配置 [root@wrx data]# cd [root@wrx ~]# cd /etc/nginx/ [root@wrx nginx]# ls conf.d default.d fastcgi.conf fastcgi.conf.default fastcgi_params fastcgi_params.default koi-utf koi-win mime.types mime.types.default nginx.conf nginx.conf.default scgi_params scgi_params.default uwsgi_params uwsgi_params.default win-utf [root@wrx nginx]# cp nginx.conf nginx.conf.bak [root@wrx nginx]# vim nginx.conf #nginx.conf文件内容如下 # For more information on configuration, see: # * Official English Documentation: http://nginx.org/en/docs/ # * Official Russian Documentation: http://nginx.org/ru/docs/ user nginx; worker_processes auto; error_log /var/log/nginx/error.log; pid /var/run/nginx.pid; # Load dynamic modules.

附:
使用yum安装nginx时出现如下问题
warning: rpmts_HdrFromFdno: Header V3 RSA/SHA256 Signature, key ID 0608b895: NOKEY Retrieving key from file:///etc/pki/rpm-gpg/RPM-GPG-KEY-EPEL-6 GPG key retrieval failed: [Errno 14] Could not open/read
解决办法
#首先查看/etc/pki/rmp-gpg目录是否存在RPM-GPG-KEY-EPEL-6文件 [root@wrx ~]# ls /etc/pki/rmp-gpg ls: cannot access /etc/pki/rmp-gpg: No such file or directory #如果不存在 [root@wrx ~]# wget -O /etc/pki/rpm-gpg/RPM-GPG-KEY-EPEL-6 https://fedoraproject.org/static/0608B895.txt #导入密钥密令 [root@wrx ~]# rpm --import /etc/pki/rpm-gpg/RPM* #再次使用yum命令安装nginx试试看
