Nginx 官方網站 www.nginx.org
第一步：在/usr/local下創建nginx目錄並進入
(1 ) mkdir /usr/local/nginx
- cd /usr/local/nginx
下載nginx相應的版本，wget 版本路徑例如：
第二步：解壓：
- tar zxvf nginx-1.10.2.tar.gz
第三步執行配置初始化：進入解壓文件夾 nginx
[root@vw010001135067 local]# cd nginx-1.10.2
[root@vw010001135067 nginx-1.10.2]#./configure --help
可以查看configure 的參數寫法以及相應的參數
[root@vw010001135067 nginx-1.10.2]#./configure --prefix=/usr/local/nginx
配置nginx的安裝路徑
執行configure配置不成功遇到的問題：報錯如下：
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
出現這個錯誤。那麼就是gcc 包沒有安裝。
1.3.1 安裝gcc
查看gcc命令
[root@vw010001135067 nginx-1.10.2]# whereis gcc
gcc:
安裝gcc
[root@vw010001135067 nginx-1.10.2]# yum -y install gcc
安裝成功後再次查看
[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安裝好了。
1.3.2 繼續執行./configure
[root@vw010001135067 nginx-1.10.2]# ./configure
checking for OS
+ Linux 2.6.32-431.el6.x86_64 x86_64

./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出現如上錯誤。安裝pcre-devel
[root@vw010001135067 nginx-1.10.2]# yum install pcre-devel
[1.3.3 再次執行./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如果有這個錯誤 那麼執行
yum install zlib-devel
y1.3.4 執行./configure後沒有報錯
[root@vw010001135067 nginx-1.10.2]# ./configure

[1.4 如果你想使用openssl 功能，sha1 功能。 那麼安裝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 開啓ssl 模塊 執行./configure –with-http_ssl_module
[root@vw010001135067 nginx-1.10.2]# ./configure --with-http_ssl_module
1.4.2 啓用“server+status”頁，執行./configure –with-http_stub_status_module
[root@vw010001135067 nginx-1.10.2]# ./configure --with-http_stub_status_module
上面兩個命令同時啓動可以
[root@vw010001135067 nginx-1.10.2]# ./configure --with-http_stub_status_module --with-http_ssl_module
執行make 命令，執行make install 命令1.5 上面configure就通過了
[root@vw010001135067 nginx-1.10.2]# make
[root@vw010001135067 nginx-1.10.2]# make install
至此，nginx 執行成功了
1.6 配置環境變量
在/etc/profile 中加入配置
打開配置文件
[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
我開始像上面填寫，結果nginx -v的時候查找不到。注意到上面我的nginx_home配置的地址不對。先找到nginx的安裝地址
[root@vw010001135067 nginx-1.10.2]# whereis nginx
nginx: /usr/local/nginx
編譯完保存退出並執行還真是地址寫錯了，把上面的改成
#nginx configure
export NGINX_HOME=/usr/local/nginx
export PATH=$PATH:$NGINX_HOME/sbin
編譯完保存退出並執行
[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服務在http://10.1.135.67/，配置成功後，現在啓動nginx2.1 啓動nginx整個過程成功了！
[root@vw010001135067 nginx]# cd /usr/local/nginx
[root@vw010001135067 nginx]# nginx -c conf/nginx.conf
ot啓動成功，在瀏覽器打開http://10.1.135.67/，默認端口號80.
如上圖，nginx已經正常工作了。
遇到問題：瀏覽器訪問不通的問題
很多時候，安裝完成後，服務也啓動了
但是訪問不了
看看是不是防火牆開啓了；
本地試下端口是否可訪問telnet 192.168.4.155 80
本地機器測試nginx是否能正常啓動
所謂的本地機器，就是你安裝了nginx軟件的那一臺機器，輸入命令：
curl http://192.168.241.129/
這裏的ip地址爲你本機的ip地址然後會有結果：
[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]#
以上驗證了本地是已經安裝成功的了，
但是我們遠程訪問的時候就是訪問不了，一直說拒絕訪問，那就是可能真的跟端口，防火牆有關了。
防火牆、端口開啓設置
打開80端口：
vi /etc/sysconfig/iptables
-A INPUT -p tcp -m state --state NEW -m tcp --dport 80 -j ACCEPT
CentOS 7默認使用的是firewall作爲防火牆，這裏改爲iptables防火牆。
firewall：
systemctl start firewalld.service#啓動firewall
systemctl stop firewalld.service#停止firewall
systemctl disable firewalld.service#禁止firewall開機啓動
Iptables stop
