1 基于ansible role实现编译安装nginx
利用ansible控制端10.0.0.8机器，在被控制端10.0.0.18上部署nginx
首先打通ansible控制端与被控制端的基于key验证
[root@ansible-rocky ~]$ ssh-copy-id 10.0.0.18 [root@ansible-rocky ~]$ ssh 10.0.0.18 Last login: Wed Jan 11 12:18:28 2023 from 10.0.0.8 [root@rocky8 ~]$ hostname -I 10.0.0.18
然后创建nginx项目目录实现基于role的部署任务

在被控制端检查是否安装完成
2 编译安装参数详解
编译安装参数示例：
./configure --prefix={{install_dir}} \
--user=nginx \
--group=nginx \
--with-http_ssl_module \
--with-http_v2_module \
--with-http_realip_module \
--with-http_stub_status_module \
--with-http_gzip_static_module \
--with-pcre \
--with-stream \
--with-stream_ssl_module \
--with-stream_realip_module
在编译安装参数中--with开头的选项默认是禁用的，想要使用的话就需要在编译的时候加上；without开头的选项默认是开启的，不想要启用此模块的话就需要在编译的时候加上。
通用配置选项参数：
--user 指定的值。安装后，可以使用 nginx.conf 中的 user 指令更改。默认开启的模块
默认未开启模块
perl模块相关选项参数
邮件模块相关配置选项参数
stream模块相关参数
