我可以真見識了 SELinux 的利害了， 這個問題讓我找了好長時間的原因:
結果是 SELinux 不讓 httpd 訪問外網，昨天安裝 Chrome 瀏覽器，結果不讓 在根帳號下運行 .....
SQLSTATE[HY000] [2003] Can't connect to MySQL server on 'XXX' (13)
解決方法:
Selinux 的設置 Can't connect to MySQL (13)
|
通過php的mysql_connect('localhost','usr','pass')連接本地數據庫成功
但是，mysql_connect('127.0.0.1:3306','usr','pass')出現
can't connect to MySQL server using '' (13)的錯誤
原因：
#getsebool -a | grep httpd
[neo@neo phpMyTest]$ 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_read_user_content --> off
httpd_setrlimit --> off
httpd_ssi_exec --> off
httpd_tmp_exec --> off
httpd_tty_comm --> on
httpd_unified --> off
httpd_use_cifs --> off
httpd_use_gpg --> off
httpd_use_nfs --> off
發現 httpd_can_network_connect --> off
解決方案：
#setsebool httpd_can_network_connect 1
