centos7 rpm安装nginx

一、下载nginx rpm包

地址为：

http://nginx.org/packages/centos/7/x86_64/RPMS/

下载nginx-1.18.0-1.el7.ngx.x86_64包

[root@iZ2ze6bgt1xmvd4jc0v7nmZ src]# wget http://nginx.org/packages/centos/7/x86_64/RPMS/nginx-1.18.0-1.el7.ngx.x86_64.rpm

二、查询是否已经安装了nginx

[root@iZ2ze6bgt1xmvd4jc0v7nmZ src]# rpm -qa|grep nginx

如果有安装了，执行 rpm -e 进行卸载

三、执行rpm命令安装

rpm 安装方式nginx 默认安装位置在 /etc/nginx/ 目录下

[root@iZ2ze6bgt1xmvd4jc0v7nmZ src]# rpm -ivh nginx-1.18.0-1.el7.ngx.x86_64.rpm 
warning: nginx-1.18.0-1.el7.ngx.x86_64.rpm: Header V4 RSA/SHA1 Signature, key ID 7bd9bf62: NOKEY

五、查询nginx

[root@iZ2ze6bgt1xmvd4jc0v7nmZ local]# systemctl status nginx
● nginx.service - nginx - high performance web server
   Loaded: loaded (/usr/lib/systemd/system/nginx.service; disabled; vendor preset: disabled)

六、访问web

[root@iZ2ze6bgt1xmvd4jc0v7noZ ~]# curl 172.27.6.3
<!DOCTYPE html>
<html>
<head>
<title>Welcome to nginx!</title>
<style>
    body {
         35em;
        margin: 0 auto;
        font-family: Tahoma, Verdana, Arial, sans-serif;

[root@iZ2ze6bgt1xmvd4jc0v7noZ ~]#

七、设置开机自启动

查询nginx是否开机自启动

[root@iZ2ze6bgt1xmvd4jc0v7nmZ local]# systemctl list-unit-files |grep nginx
nginx-debug.service                           disabled
nginx.service                                 disabled
[root@iZ2ze6bgt1xmvd4jc0v7nmZ local]#

设置允许开机自启动

[root@iZ2ze6bgt1xmvd4jc0v7nmZ local]# systemctl enable nginx 
Created symlink from /etc/systemd/system/multi-user.target.wants/nginx.service to /usr/lib/systemd/system/nginx.service

再次查询

[root@iZ2ze6bgt1xmvd4jc0v7nmZ local]# systemctl list-unit-files|grep nginx
nginx-debug.service                           disabled
nginx.service                                 enabled 
[root@iZ2ze6bgt1xmvd4jc0v7nmZ local]#

rpm 安装方式nginx 默认安装位置在 /etc/nginx/ 目录下

八、卸载

[root@iZ2ze6bgt1xmvd4jc0v7nmZ nginx]# rpm -qa|grep nginx
nginx-1.18.0-1.el7.ngx.x86_64

停止nginx服务

[root@iZ2ze6bgt1xmvd4jc0v7nmZ nginx]# systemctl stop nginx

卸载

[root@iZ2ze6bgt1xmvd4jc0v7nmZ nginx]# rpm -e nginx
