作为一个习惯追新的人，最近把nginx升级到了1.15.2，修改站点配置并重新加载配置文件时，发现报警告。 虽然不影响正常，也不是处女座，但还是看不顺眼，经过一番百度 Google，终于找到原因和解决方法！
报错内容
代码语言：javascript复制nginx: [warn] the "ssl" directive is deprecated, use the "listen ... ssl" directive instead in /usr/local/nginx/conf/vhost/test.ll00.cn:24原因
新版本不推荐使用ssl指令，所以会发出一段警告。使用listen 443 ssl;代替
解决方法
在配置文件里，找到ssl on;，将其注释掉
# ssl on;然后修改监听端口处的配置后面加上ssl
listen 443 ssl;相关Nginx更新日志：
