今天下午配置项目的时候发现 框架里的pdo无法连接数据库,试了好多方法发现还是连不了,在快绝望的时候,终于找到了一个和我碰见同样问题的人,解决方法如下:
[root@mio-253 ~]# getsebool -a | grep httpd
allow_httpd_anon_write --> off
allow_httpd_mod_auth_ntlm_winbind --> off
allow_httpd_mod_auth_pam --> off
allow_httpd_sys_script_anon_write --> off
httpd_builtin_scripting --> on
httpd_can_check_spam --> off
httpd_can_network_connect --> off
httpd_can_network_connect_cobbler --> off
httpd_can_network_connect_db --> off
httpd_can_network_memcache --> off
httpd_can_network_relay --> off
httpd_can_sendmail --> off
httpd_dbus_avahi --> on
httpd_enable_cgi --> on
httpd_enable_ftp_server --> off
httpd_enable_homedirs --> off
httpd_execmem --> off
httpd_manage_ipa --> off
httpd_read_user_content --> off
httpd_run_stickshift --> off
httpd_setrlimit --> off
httpd_ssi_exec --> off
httpd_tmp_exec --> off
httpd_tty_comm --> on
httpd_unified --> on
httpd_use_cifs --> off
httpd_use_gpg --> off
httpd_use_nfs --> off
httpd_use_openstack --> off
httpd_verify_dns --> off
[root@mio-253 ~]# setsebool -P httpd_can_network_connect_db=1
发现终于可以连接上数据库了,然后问了下运维,才知道可能是selinux阻止访问外部数据库,可以关闭掉,方法如下:
/usr/sbin/setenforce 0 立刻关闭 SELINUX
/usr/sbin/setenforce 1 立刻启用 SELINUX
加到系统默认启动里面
echo "/usr/sbin/setenforce 0" >> /etc/rc.local
