phpmyadmin报错:#2003 无法登录 MySQL服务器 与SQLSTATE[HY000] [2003] Can't connect to MySQL

决方法:

Selinux 的设置 Can't connect to MySQL (13)


通过php的mysql_connect('localhost','usr','pass')连接本地数据库成功
但是,mysql_connect('127.0.0.1:3306','usr','pass')出现
can't connect to MySQL server using '' (13)的错误
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

发现 httpd_can_network_connect --> off

解决方案:

#setsebool httpd_can_network_connect 1
