在yum启动nginx服务的时候出现: [root@web02 ~]# /etc/init.d/nginx Usage: /etc/init.d/nginx {start|stop|reload|configtest|status|force-reload|upgrade|restart|reopen_logs} [root@web02 ~]# /etc/init.d/nginx start Starting nginx: nginx: [emerg] socket() [::]:80 failed (97: Address family not supported by protocol) [FAILED]

解决办法: 1、修改配置文件前先备份: [root@web01 tools]# cp /etc/nginx/conf.d/default.conf /etc/nginx/conf.d/default.conf.bak 2、修改配置文件: [root@web01 tools]# vim /etc/nginx/conf.d/default.conf 将 listen 80 default_server; listen [::]:80 default_server; 改为: listen 80; #listen [::]:80 default_server;
