使用yum命令安装OpenResty，具体步骤如下：，，1. 打开终端，输入以下命令更新系统软件包：，，``，sudo yum update，`，，2. 安装必要的开发工具和库文件：，，`，sudo yum groupinstall "Development Tools"，sudo yum install openssl-devel pcre-devel zlib-devel gcc，`，，3. 下载OpenResty的源代码包，可以从官方网站下载最新版本的源码包。，，4. 解压源代码包并进入解压后的目录：，，`，tar -zxvf openresty-x.x.x.tar.gz，cd openresty-x.x.x，`，，5. 运行以下命令进行配置：，，`，./configure --prefix=/usr/local/openresty --with-http_ssl_module --with-http_gzip_static_module --with-pcre --with-zlib --with-openssl=/usr/bin/openssl，`，，6. 编译并安装OpenResty：，，`，make && sudo make install，`，，7. 将OpenResty添加到系统环境变量中：，，`，echo 'export PATH=$PATH:/usr/local/openresty/bin' >> ~/.bashrc，source ~/.bashrc，`，，8. 启动OpenResty：，，`，openresty -V，``

在CentOS 7.6上安装OpenResty的步骤如下：

1、更新系统软件包

```

sudo yum update

```

2、安装依赖项

```

sudo yum install y gcc gccc++ make zlibdevel pcredevel openssldevel

```

3、下载OpenResty源码

```

wget https://openresty.org/download/openrestyx.y.z.tar.gz

```

4、解压源码并进入目录

```

tar xvf openrestyx.y.z.tar.gz

cd openrestyx.y.z

```

5、配置编译选项

```

./configure prefix=/usr/local/openresty withhttp_stub_status_module withhttp_ssl_module withpcre withopenssl=/usr/bin/openssl

```

6、编译和安装OpenResty

```

make && sudo make install

```

7、创建OpenResty服务文件

```

sudo nano /usr/lib/systemd/system/openresty.service

```

8、将以下内容粘贴到服务文件中，替换/usr/local/openresty为实际安装路径，并保存文件。
