一個centos下的配置問題

標籤：

　　今天下午設定項目的時候發現 架構裡的pdo無法串連資料庫,試了好多方法發現還是連不了,在快絕望的時候,終於找到了一個和我碰見同樣問題的人,解決方案如下:

　　

[[email protected] ~]# 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

[[email protected] ~]# setsebool -P httpd_can_network_connect_db=1

發現終於可以串連上資料庫了,然後問了下營運,才知道可能是selinux阻止訪問外部資料庫,可以關閉掉,方法如下:

/usr/sbin/setenforce 0 立刻關閉 SELINUX
/usr/sbin/setenforce 1 立刻啟用 SELINUX

加到系統預設啟動裡面
echo "/usr/sbin/setenforce 0" >> /etc/rc.local
