一、给lua指定证书

code
# fix lua ssl certificate verify error lua ssl certificate verify error: (20: unable to get local issuer certificate) 
#bash
yum install ca-certificates
update-ca-trust
cp /etc/ssl/certs/ca-certificates.crt /etc/ssl/certs/ca-lua.pem
 
#Nginx.conf
lua_ssl_verify_depth 2;
lua_ssl_trusted_certificate '/etc/ssl/certs/ca-lua.pem';

二、碰到的其他题目处理

code
#nginx.conf
resolver 223.5.5.5 223.6.6.6 1.2.4.8 114.114.114.114 8.8.8.8 valid=3600s;
