开启rewrite 日志(反向代理不生效,排查)
- 设置nginx.conf配置文件中的错误日志级别为
notice（nginx中最低级别的错误）并开启rewrite重写代理地址日志
error_log logs/error.log notice; # 开启低级别log
rewrite_log on; # 开启重写代理地址日志
demo
# user nobody;
# error_log logs/error.log;
error_log logs/error.log notice; # 开启低级别log
# error_log logs/error.log info;
http {
rewrite_log on; # 开启重写代理地址日志
# ... 其他配置 ...
}
