环境描述： 1、oracle 11g R2 2、linux(centos6.2)服务器 3、client(win7-64bit) 4、刚刚在win7环境下安装好win64_oracle11gR2_client (下载地址：http://download.oracle.com/otn/nt/oracle11g/112010/win64_11gR2_client.zip) 操作： 1、打开终端输入 sql

环境描述：

1、oracle 11g R2

2、linux(centos6.2)服务器

3、client(win7-64bit)

4、刚刚在win7环境下安装好win64_oracle11gR2_client (下载地址：http://download.oracle.com/otn/nt/oracle11g/112010/win64_11gR2_client.zip)

操作：

1、打开终端输入 sqlplus system/oracle@chenhao01 (注意：chenhao01代表tnsnames.ora配置的名称。一下会贴出我的tnsnames.ora的文件代码)

(1、的操作出现一下错误:ORA-12154: TNS: could not resolve the connect identifier specified)

原因是：没有配置tns

2、找到 tnsnames.ora文件(我的这个文件是在 D:\softInstall\oracle_client\Administrator\product\11.2.0\client_1\network\admin\sample目录下注意：一般路劲

D:\softInstall\oracle_client\Administrator\product\11.2.0\client_1 是在环境变量 path 中能找到的)

3、将tnsnames.ora备份一份打开tnsnames.ora将所有内容换成

chenhao01 =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.126.129)(PORT = 1521))
)
(CONNECT_DATA =
(SERVICE_NAME = chenhao)
)
)

(注意：这里的HOST、POST、SERViCE_NAME是我linux服务器中的，chenhao01 是和在终端输入 sqlplus system/oracle@chenhao01 中的chenhao01是对应的)

4、配置好保存重新打开终端输入 sqlplus system/oracle@chenhao01 此时还会出现ORA-12154: TNS: could not resolve the connect identifier specified

原因是我将 tnsnames.ora文件放在了 D:\softInstall\oracle_client\Administrator\product\11.2.0\client_1\network\admin\sample下

5、将配置好的tnsnames.ora文件放在 D:\softInstall\oracle_client\Administrator\product\11.2.0\client_1\network\admin 下

6、再次重新打开终端输入 sqlplus system/oracle@chenhao01 (如果出现一下错误：ORA-12170 TNS 连接超时)

原因可能是：linux中的防火墙打开了只需要将linux中的防火墙关闭之后再win7 终端输入 sqlplus system/oracle@chenhao01

7、祝你成功，希望对你有帮助

MySQL: Adding a user through a PHP web interfaceMay 14, 2025 am 12:04 AM

Adding MySQL users through the PHP web interface can use MySQLi extensions. The steps are as follows: 1. Connect to the MySQL database and use the MySQLi extension. 2. Create a user, use the CREATEUSER statement, and use the PASSWORD() function to encrypt the password. 3.
