nginx常见报错及处理方式

1：
bind() to 0.0.0.0:80 failed (10013: An attempt was made to access a socket in a way forbidden by its access permissions)

说明有程序在占用80端口，把占用端口的程序干掉，重启

2：
could not build the server_names_hash, you should increase server_names_hash_bucket_size: 32

在配置文件的http{}段增加一行配置
server_names_hash_bucket_size 64;
如果64还不够，那么就按32的倍数往上加。
