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
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
