环境：数据库版本Oracle Database 11g Enterprise Edition Release 11.2.0.1.0 VBOX虚拟机主机名、数据库实例、库名及IP规划：源

环境：
数据库版本Oracle Database 11g Enterprise Edition Release 11.2.0.1.0
VBOX虚拟机
主机名、数据库实例、库名及IP规划：
源主机IP：192.168.1.213 HOSTNAME:bys001.oel.com
目标主机IP：192.168.1.213 HOSTNAME:bys2.oel.com
实例名和数据库名两台主机一样，两台主机的数据库结构完全一样。
采用先配置源主机，再克隆一台修改一下配置做为目标机。
其中源主机已经安装好ORACLE数据库软件并已经创建数据库。

整个配置分6步：
1.修改环境变量，创建目录
2.上传OGG软件解压并安装
3.查询数据库名、实例名并开启归档模式，，强制产生日志等
4.在数据库中为OGG创建用户
5.开始配置OGG的同步--未配置DDL的同步
6.测试test用户的test1表做DML操作能否同步
######################################
1.修改环境变量，创建目录 [oracle@bys001 ~]$ vi .bash_profile
增加这一句：
export OGG_HOME=/u01/ogg
".bash_profile" 24L, 560C written
[oracle@bys001 ~]$ source .bash_profile
[oracle@bys001 ~]$ cd /u01
[oracle@bys001 u01]$ mkdir ogg
[oracle@bys001 u01]$ ls
admin checkpoints oradata
app diag oraInventory
archbys1 flash_recovery_area
cfgtoollogs ogg
[oracle@bys001 u01]$ echo $OGG_HOME
/u01/ogg

2.上传OGG软件解压并安装 ----使用SSH SECURE SHELL上传很好用。
[oracle@bys001 ~]$ ls ogg112101_fbo_ggs_Linux_x86_ora11g_32bit.zip ogg112101_fbo_ggs_Linux_x86_ora11g_32bit.zip
[oracle@bys001 ~]$ unzip ogg112101_fbo_ggs_Linux_x86_ora11g_32bit.zip
[oracle@bys001 ~]$ ls fbo_ggs_Linux_x86_ora11g_32bit.tar
fbo_ggs_Linux_x86_ora11g_32bit.tar

[oracle@bys001 ~]$ tar -xvf fbo_ggs_Linux_x86_ora11g_32bit.tar -C $OGG_HOME

打开 ggsci时的一个错误解决：
我这里在使用ggsci遇到错误因为找不到库文件报错：
[oracle@oel-01 ogg]$ ./ggsci
./ggsci: error while loading shared libraries: libnnz11.so: cannot open shared object file: No such file or directory
建议在使用前先在OGG的目录执行：[oracle@bys001 ogg]$ ldd ggsci
如果库文件全在，可以直接执行[oracle@bys001 ogg]$ ./ggsci
如果缺少库文件，可以find / -name libnnz11.so 这样在整个/目录下查询。
根据查出的库文件位置，做一个软链接就可以了，要使用 root账户。如：
[root@oel-01 ~]# ln -s /u01/app/oracle/product/11.2.0/dbhome_1/lib/libnnz11.so /lib/libnnz11.so

创建OGG目录：要注意在OGG的安装目录下调用
[oracle@bys001 ogg]$ ./ggsci

GGSCI (bys001.oel.com) 2> create subdirs

Creating subdirectories under current directory /u01/ogg

Parameter files /u01/ogg/dirprm: already exists
Report files /u01/ogg/dirrpt: created
Checkpoint files /u01/ogg/dirchk: created
Process status files /u01/ogg/dirpcs: created
SQL script files /u01/ogg/dirsql: created
Database definitions files /u01/ogg/dirdef: created
Extract data files /u01/ogg/dirdat: created
Temporary files /u01/ogg/dirtmp: created
Stdout files /u01/ogg/dirout: created
只需要在打开的窗口写入： PORT 7809就可以了，使用是和VI一样。
GGSCI (bys001.oel.com) 4> edit param mgr
PORT 7809
GGSCI (bys001.oel.com) 7> start mgr
Manager started.

GGSCI (bys001.oel.com) 8> info all

Program Status Group Lag at Chkpt Time Since Chkpt
MANAGER RUNNING

OGG安装完成。因为后面才会克隆虚拟机，所以这里只需要做一次安装哈哈。
OGG同步的配置在第6步。

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. Prevent SQL injection and use the mysqli_real_escape_string() function to process user input. 4. Assign permissions to new users and use the GRANT statement.
