Nginx 配置遇到问题

1 

connect() to 10.2.20.170:1009 failed (13: Permission denied) while connecting to upstream

现这个错误是因为selinux， linux安全增强的补丁导致的。

解决方法是禁用selinux的安全增强， 可以使用命令 setenforce 0来临时禁用，或者通过修改配置文件/etc/sysconfig/selinux 添加 SELINUX=disabled来永久禁用

然后重启 reboot

# This file controls the state of SELinux on the system.
# SELINUX= can take one of these three values:
#     enforcing - SELinux security policy is enforced.
#     permissive - SELinux prints warnings instead of enforcing.
#     disabled - No SELinux policy is loaded.
SELINUX=disabled
# SELINUXTYPE= can take one of these two values:
#     targeted - Targeted processes are protected,
#     mls - Multi Level Security protection.
SELINUXTYPE=targeted
