我在阿里云ECS服务器上配置https多站点的时候，遇到了这样的问题：
这是nginx的配置文件:
server {
listen 443 ssl;
server_name domain1;
ssl on;
root /usr/local/nginx/html;
ssl_certificate cert/domain1.pem;
ssl_certificate_key cert/domain1.key;
index index.php index.html index.htm
ssl_session_timeout 5m;

ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
ssl_prefer_server_ciphers on;
location ~ \.php {
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
index index.php index.html index.htm;
fastcgi_split_path_info ^(.+\.php)(.*)$;
fastcgi_param PATH_INFO $fastcgi_path_info;
fastcgi_param SCRIPT_FILENAME /usr/local/nginx/html/$fastcgi_script_name;
fastcgi_connect_timeout 300;
fastcgi_send_timeout 300;
fastcgi_read_timeout 300;
include fastcgi_params;
}
}
server {
listen 443;
server_name domain2;
ssl on;
ssl_certificate cert/1_domain2_bundle.crt;
ssl_certificate_key cert/2_domain2.key;
ssl_session_timeout 5m;
ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
ssl_ciphers AESGCM:ALL:!DH:!EXPORT:!RC4:+HIGH:!MEDIUM:!LOW:!aNULL:!eNULL;
ssl_prefer_server_ciphers on;
location ~ \.php {
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
fastcgi_split_path_info ^(.+\.php)(.*)$;
fastcgi_param PATH_INFO $fastcgi_path_info;
fastcgi_param SCRIPT_FILENAME /usr/local/nginx/html/dzt666/phphelper/public/$fastcgi_script_name;
root /usr/local/nginx/html/dzt666/phphelper/public;
index index.php index.html index.htm;
}
}
server {
listen 443;
server_name domain3;
root /usr/local/nginx/html/dzt666/lostandfound/public/;
index index.php index.html index.htm;
ssl on;
ssl_certificate cert/1_domain3_bundle.crt;
ssl_certificate_key cert/2_domain3.key;
ssl_session_timeout 5m;
ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
ssl_ciphers AESGCM:ALL:!DH:!EXPORT:!RC4:+HIGH:!MEDIUM:!LOW:!aNULL:!eNULL;
ssl_prefer_server_ciphers on;
location ~ \.php {
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
fastcgi_split_path_info ^(.+\.php)(.*)$;
fastcgi_param PATH_INFO $fastcgi_path_info;
fastcgi_param SCRIPT_FILENAME /usr/local/nginx/html/dzt666/lostandfound/public/$fastcgi_script_name;
#root /usr/local/nginx/html/dzt666/lostandfound/public/;
#index index.php index.html index.htm;
}
}
这是在终端ping出的结果：

domain1能正常访问，domain3不能正常访问，请教各位前辈，我的配置哪里出了问题，该怎么来处理这类的问题？
阿里云ECS中，同一服务器下的不同域名ping出了不同的IP，可能有以下几种情况：
网络环境问题：可能因为网络环境的问题导致不同域名无法ping出同一IP地址，比如DNS解析的问题、防火墙设置问题等。
DNS缓存问题：DNS缓存可能会导致不同域名ping出同一IP地址，比如DNS缓存中的某个域名出现问题，导致解析失败，从而ping出了不同的IP地址。
服务器负载问题：如果服务器负载过高，可能会导致不同域名ping出同一IP地址，比如CPU、内存等资源使用过高，导致响应速度变慢。
异常问题：如果服务器出现异常，可能会导致不同域名ping出同一IP地址，比如服务器宕机、网络故障等。
解决这些问题的方法包括：
检查网络环境，确保DNS解析正常，防火墙设置正常。
清理DNS缓存，或者更新DNS缓存。
优化服务器配置，比如增加CPU、内存等资源。
如果服务器出现异常，需要及时处理，避免异常影响其他域名的ping请求。
