前提条件:在安装Linux时最好安装上以下软件,否则在安装Oracle过程中不能通过先决条件检测。(在检测后也可以安装缺少的软件,但会由于软件之间的依赖关系,导致安装非常困难,,最坏条件下,导致系统重装)

1.     在root模式下修改内核参数

#vi  /etc/sysctl.conf

在代码结尾添加如下代码:

fs.file-max = 6815744

 

kernel.shmmni = 4096

kernel.shmmax = 4294967295 #物理内存一半

kernel.sem=250 32000 100 128

net.ipv4.ip_local_port_range = 9000 65500

net.core.rmem_default = 262144

net.core.rmem_max = 4194304

net.core.wmem_default = 262144

net.core.wmem_max = 10488576

fs.aio-max-nr = 10488576

保存并退出

#/sbin/sysctl –p 使修改生效

2.     为oracle用户设置shell限制

#vi /etc/security/limits.conf

在文件尾部添加下列代码:

oracle  soft nproc 2047

oracle  hard nproc 16384

oracle  soft nofile 1024

oracle  hard nofile 65536

oracle -   nofile 1006154

保存退出

3.     在root模式下创建oracle用户和组

#groupadd oinstall

#groupadd dba

#groupadd oper

#useradd –g oinstall –G dba,oper oracle //增加了oracle用户

#passwd oracle (在下面出现的命令行中设置oracle账户口令)

4.     为安装oracle建立目录

#cd /home/oracle  //转到oracle目录下

#mkdir app       //建立app目录

#chown –R oracle:oinstall /home/oracle/app  

#chmod –R 775 /home/oracle/app            //赋予权限

5.     切换到oracle账户并为oracle用户设置环境变量

#su – oracle

$vi /home/oracle/.bash_profile

在文件中添加:

export ORACLE_BASE=/home/oracle/app

export ORACLE_HOME=$ORACLE_BASE/product/11.1.0/db_1

export ORACLE_SID=orcl (自己定义的名称)

export PATH=$ORACLE_HOME/bin:$PATH
export LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib
export CLASSPATH=$ORACLE_HOME/JRE:$ORACLE_HOME/jlib:$ORACLE_HOME/rdbms/jlib
export NLS_LANG="SIMPLIFIED CHINESE_CHINA".ZHS16GBK

保存退出

$source /home/oracle/.bash_profile 使其生效

6.重新启动操作系统:
# reboot (重新启动命令)
特别说明:因为安装Oracle软件时不可使用root(超级用户)来进行安装,只可以使用刚才新建的oracle用户来进行安装,请大家一定要注意!

7.通过FTP工具把oracle11g压缩包复制到oracle文件夹下面

8.在oracle模式下解压oracle11g压缩包

#unzip linux.x64_11gR2_database_1of2.zip –d  /home/oracle

#unzip linux.x64_11gR2_database_2of2.zip –d  /home/oracle

 

9.新开一个终端窗口,以root身份执行命令 #xhost  +

10.然后回到oracle窗口

进入database目录

$cd /home/oracle/database

$./runInstaller

开始安装。剩下的安装步骤和在windows下一样。

到最后千万要执行最后两个命令。

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.
