今天測試Docker下配置一個nginx模板的鏡像，裝好nginx後，使用nginx -t進行檢查，報錯如下：

[[email protected] yum.repos.d]# nginx -t
nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: [emerg] socket() [::]:80 failed (97: Address family not supported by protocol)
nginx: configuration file /etc/nginx/nginx.conf test failed

檢查配置文件：

    server {
        listen       80 default_server;
        listen       [::]:80 default_server;
根據錯誤提示分析，監聽的方式可能不支持ipv6，於是將其註釋掉
    server {
        listen       80 default_server;
#        listen       [::]:80 default_server;
然後再次檢查配置：
[[email protected] yum.repos.d]# nginx -t
nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: configuration file /etc/nginx/nginx.conf test is successful
沒有報錯了，問題解決
