linux下nginx安装及简单使用教程

（一）1.使用yum安装nginx，如下图。显示安装成功。

yum install nginx

2.首先我们查看一下nginx的版本，yum默认安装的版本是1.12.2

nginx -v

3.启动一下nginx看一下，没有任何提示信息，表明我们启动成功了。

nginx

4.查看一下端口可知，nginx默认的端口号是80端口。

netstat -ntlp

5.访问一下安装nginx的电脑ip地址，出现以下界面表示启动成功了。

以下是Nginx的默认路径：

(1) Nginx配置路径：/etc/nginx/

(2) PID目录：/var/run/nginx.pid

(3) 错误日志：/var/log/nginx/error.log

(4) 访问日志：/var/log/nginx/access.log

(5) 默认站点目录：/usr/share/nginx/html

6.我们看一下nginx的配置文件，不知道位置的情况下使用find命令检索一下电脑

find / -name nginx.conf

cat /etc/nginx/nginx.conf

        include /etc/nginx/default.d/*.conf;

        location / {

        error_page 404 /404.html;
            location = /40x.html {

    }

}

注：nginx常用相关命令

nginx -v         #查看版本
nginx            #启动命令
nginx -s stop    #停止
nginx -t         #修改完nginx.conf后检查语法是否正确
nginx -s -reload #重启（修改完配置文件可以使用此命令重新加载配置文件）
