Nginx 官方网站 www.nginx.org
第一步：在/usr/local下创建nginx目录并进入
(1 ) mkdir /usr/local/nginx
- cd /usr/local/nginx
下载nginx相应的版本，wget 版本路径例如：
第二步：解压：
- tar zxvf nginx-1.10.2.tar.gz
第三步执行配置初始化：进入解压文件夹 nginx
[root@vw010001135067 local]# cd nginx-1.10.2
[root@vw010001135067 nginx-1.10.2]#./configure --help
可以查看configure 的参数写法以及相应的参数
[root@vw010001135067 nginx-1.10.2]#./configure --prefix=/usr/local/nginx
配置nginx的安装路径
执行configure配置不成功遇到的问题：报错如下：
checking for OS
+ Linux 2.6.32-431.el6.x86_64 x86_64
checking for C compiler ... not found
./configure: error: C compiler cc is not found
出现这个错误。那么就是gcc 包没有安装。
1.3.1 安装gcc
查看gcc命令
[root@vw010001135067 nginx-1.10.2]# whereis gcc
gcc:
安装gcc
[root@vw010001135067 nginx-1.10.2]# yum -y install gcc
安装成功后再次查看
[root@vw010001135067 nginx-1.10.2]# whereis gcc
gcc: /usr/bin/gcc /usr/lib/gcc /usr/libexec/gcc /usr/share/man/man1/gcc.1.gz
gcc安装好了。
1.3.2 继续执行./configure
[root@vw010001135067 nginx-1.10.2]# ./configure

./configure: error: the HTTP rewrite module requires the PCRE library.
You can either disable the module by using --without-http_rewrite_module
option, or install the PCRE library into the system, or build the PCRE library
statically from the source with nginx by using --with-pcre=<path> option.
[r出现如上错误。安装pcre-devel
[root@vw010001135067 nginx-1.10.2]# yum install pcre-devel
[1.3.3 再次执行./configure
error: the HTTP gzip module requires the zlib library.
You can either disable the module by using --without-http_gzip_module
option, or install the zlib library into the system, or build the zlib library
statically from the source with nginx by using --with-zlib=<path> option.
e如果有这个错误 那么执行
yum install zlib-devel
y1.3.4 执行./configure后没有报错
[root@vw010001135067 nginx-1.10.2]# ./configure

[1.4 如果你想使用openssl 功能，sha1 功能。 那么安装openssl ，sha1 吧
[root@vw010001135067 nginx-1.10.2]# yum install openssl openssl-devel
[root@vw010001135067 nginx-1.10.2]# install perl-Digest-SHA1.x86_64
1.4.1 开启ssl 模块 执行./configure –with-http_ssl_module
[root@vw010001135067 nginx-1.10.2]# ./configure --with-http_ssl_module
1.4.2 启用“server+status”页，执行./configure –with-http_stub_status_module
[root@vw010001135067 nginx-1.10.2]# ./configure --with-http_stub_status_module
上面两个命令同时启动可以
[root@vw010001135067 nginx-1.10.2]# ./configure --with-http_stub_status_module --with-http_ssl_module
执行make 命令，执行make install 命令1.5 上面configure就通过了
[root@vw010001135067 nginx-1.10.2]# make
[root@vw010001135067 nginx-1.10.2]# make install
至此，nginx 执行成功了
1.6 配置环境变量
在/etc/profile 中加入配置
打开配置文件
[root@vw010001135067 nginx-1.10.2]# vi /etc/profile
在配置文件中加入
#nginx configure
export NGINX_HOME=/usr/local/nginx-1.10.2
export PATH=$PATH:$NGINX_HOME/sbin
我开始像上面填写，结果nginx -v的时候查找不到。注意到上面我的nginx_home配置的地址不对。先找到nginx的安装地址
[root@vw010001135067 nginx-1.10.2]# whereis nginx
nginx: /usr/local/nginx
编译完保存退出并执行还真是地址写错了，把上面的改成
#nginx configure
export NGINX_HOME=/usr/local/nginx
export PATH=$PATH:$NGINX_HOME/sbin
编译完保存退出并执行
[root@vw010001135067 nginx-1.10.2]# source /etc/profile
使配置生效。
1.7 查看nginx版本
[root@vw010001135067 nginx]# nginx -v
nginx version: nginx/1.10.2
我的nginx服务在http://10.1.135.67/，配置成功后，现在启动nginx2.1 启动nginx整个过程成功了！
[root@vw010001135067 nginx]# cd /usr/local/nginx
[root@vw010001135067 nginx]# nginx -c conf/nginx.conf
ot启动成功，在浏览器打开http://10.1.135.67/，默认端口号80.
如上图，nginx已经正常工作了。
遇到问题：浏览器访问不通的问题
很多时候，安装完成后，服务也启动了
但是访问不了
看看是不是防火墙开启了；
本地试下端口是否可访问telnet 192.168.4.155 80
本地机器测试nginx是否能正常启动
所谓的本地机器，就是你安装了nginx软件的那一台机器，输入命令：
curl http://192.168.241.129/
这里的ip地址为你本机的ip地址然后会有结果：
[root@localhost nginx-1.12.1]# curl http://192.168.241.129/<!DOCTYPE html><html><head><title>Welcome to nginx!</title><style>
body {
width: 35em;
margin: 0 auto;
font-family: Tahoma, Verdana, Arial, sans-serif;
}</style></head><body><h1>Welcome to nginx!</h1><p>If you see this page, the nginx web server is successfully installed and
working. Further configuration is required.</p>
<p>For online documentation and support please refer to<a href="http://nginx.org/">nginx.org</a>.<br/>
Commercial support is available at<a href="http://nginx.com/">nginx.com</a>.</p>
<p><em>Thank you for using nginx.</em></p></body></html>
[root@localhost nginx-1.12.1]#
以上验证了本地是已经安装成功的了，
但是我们远程访问的时候就是访问不了，一直说拒绝访问，那就是可能真的跟端口，防火墙有关了。
防火墙、端口开启设置
打开80端口：
vi /etc/sysconfig/iptables
-A INPUT -p tcp -m state --state NEW -m tcp --dport 80 -j ACCEPT
CentOS 7默认使用的是firewall作为防火墙，这里改为iptables防火墙。
firewall：
systemctl start firewalld.service#启动firewall
systemctl stop firewalld.service#停止firewall
systemctl disable firewalld.service#禁止firewall开机启动
Iptables stop
