nginx SLL配置 the "ssl" parameter requires ngx_http_ssl_module in nginx.c

记录一下今天给一个站点配置SSL证书遇到的问题。

修改配置

在阿里云申请到SLL证书后(过程参见《阿里云申请免费SSL证书》)上传到 nginx的 cert文件夹之后
需要修改站点对应的nginx 配置，添加如下内容(需要将.pem和.key文件名改成你的)：

    listen 443 ssl;
    ssl on;
    ssl_certificate   cert/3969078_www.xxxx.cn.pem;
    ssl_certificate_key  cert/3969078_www.xxxx.cn.key;
    ssl_session_timeout 5m;
    ssl_ciphers ECDHE-RSA-AES128-GCM-SHA256:ECDHE:ECDH:AES:HIGH:!NULL:!aNULL:!MD5:!ADH:!RC4;
    ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
    ssl_prefer_server_ciphers on;
    underscores_in_headers on;

重载nginx配置

centos7 如果配置了 server 的话可以使用以下命令重载
systemctl reload nginx

没有话使用下面的命令重载
nginx -s reload

我在重载的时候，发现报如下报错了：

nginx: [emerg] the "ssl" parameter requires ngx_http_ssl_module in /usr/local/nginx/conf/nginx.c

这个错误的原因是因为安装nginx的时候没有添加 ssl 模块

添加 nginx ssl模块

我是自己下载源码进行编译安装的，解决方法如下：

1. 安装依赖

yum -y install openssl openssl-devel

2. 在nginx源码目录执行以下命令，配置ssl模块

./configure --prefix=/usr/local/nginx --with-http_stub_status_module --with-http_ssl_module
make

3. 替换 nginx

cp ./objs/nginx /usr/local/nginx/sbin/

4. 重启nginx

systemctl restart nginx

这里我遇到一个问题，启动失败了，使用systemctl status nginx查看提示log文件不存在

$ systemctl status nginx

5. 在对应目录下创建丢失的目录

mkdir /usr/local/nginx/logs

6. 再次重启nginx即可

systemctl restart nginx
