linux中安装nginx

### 一:安装依赖

yum -y install gcc gcc-c++ automake pcre pcre-devel zlib zlib-devel open openssl-devel

二：下载nginx稳定版

 wget http://nginx.org/download/nginx-1.16.1.tar.gz 

三：解压--编译--安装

tar -zxvf nginx-1.16.1.tar.gz

cd nginx-1.16.1/
#配置vim，使其语法高亮
mkdir .vim    #自己创建一个.vim目录
cp -r contrib/vim/*  ~/.vim/

#查看编译参数
./configure --help | more  


#编译
./configure  --prefix=/usr/local/nginx

#安装：
make && make install


#去prefix指定的目录下
cd /usr/local/nginx/

[root@iZwz95n2hxcdh4x6vicjmgZ nginx]# ls -l
total 16
drwxr-xr-x 2 root root 4096 Jul  9 13:37 conf
drwxr-xr-x 2 root root 4096 Jul  9 13:37 html
drwxr-xr-x 2 root root 4096 Jul  9 13:37 logs
drwxr-xr-x 2 root root 4096 Jul  9 13:37 sbin


#nginx服务器的主程序
[root@localhost sbin]# ls /usr/local/nginx/sbin/nginx 
/usr/local/nginx/sbin/nginx

四:开放linux对外访问的端口号80

/sbin/iptables -I INPUT  -p tcp --dport 80 -j ACCEPT

五：nginx服务的启动操作

1:默认配置文件启动
cd /usr/local/nginx/sbin
./nginx 

指定配置文件启动
[root@iZwz95n2hxcdh4x6vicjmgZ sbin]# ./nginx -c  /usr/local/nginx/conf/nginx.conf

2:查看帮助信息
./ngxin =h #查看帮助信息

#可以找安装时候的配置
[root@iZwz95n2hxcdh4x6vicjmgZ sbin]# ./nginx -V
nginx version: nginx/1.16.1
built by gcc 4.8.5 20150623 (Red Hat 4.8.5-39) (GCC) 
configure arguments: --prefix=/usr/local/nginx


3：-t 检查配置文件是否正确
[root@iZwz95n2hxcdh4x6vicjmgZ sbin]# ./nginx -t
nginx: the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok
nginx: configuration file /usr/local/nginx/conf/nginx.conf test is successful

六：验证

七：nginx停服务

cd /usr/local/nginx/sbin
./nginx -s stop
