1.创建组 (1) [root@dg2 /]$mkdir u01 (2)[root@dg2 /]$groupadd oinstall (3)[root@dg2 /]$groupadd dba (4) [root@dg2 /]$useradd -g oinstall -G dba -d /u01/oracle oracle (5) [root@dg2 /]$passwd oracle 2.配置环境变量 (1) [oracle@dg2 ~]$su - orac
1.创建组
(1) [root@dg2 /]$mkdir u01
(2) [root@dg2 /]$groupadd oinstall
(3) [root@dg2 /]$groupadd dba
(4) [root@dg2 /]$useradd -g oinstall -G dba -d /u01/oracle oracle
(5) [root@dg2 /]$passwd oracle
2.配置环境变量
(1) [oracle@dg2 ~]$su - oracle
(2) 进入 /u01/oracle 目录
[oracle@dg2 ~]$ vi .bash_profile
(3) 增加如下内容(DISPLAY=192.168.174.1:0.0 图形界面相关)
ORACLE_BASE=/u01
ORACLE_HOME=$ORACLE_BASE/oracle
ORACLE_SID=poli
PATH=$ORACLE_HOME/bin:$PATH
LD_LIBRARY_PATH=$ORACLE_HOME/lib:$LD_LIBRARY_PATH
DISPLAY=192.168.174.1:0.0
export ORACLE_BASE ORACLE_HOME ORACLE_SID PATH LD_LIBRARY_PATH DISPLAY
(4) 查看配置
[oracle@dg2 ~]$ exit
[root@dg2 /]# su - oracle
[oracle@dg2 ~]$ env | grep ORA
[oracle@dg2 ~]$ env | grep DIS
(5) 解压缩oracle安装文件
[root@dg2 ~]# unzip linux_11gR2_database_1of2.zip
[root@dg2 ~]# unzip linux_11gR2_database_2of2.zip
(6) 将解压后的database 从root 转移u01
[root@dg2 /]# cd /
[root@dg2 /]# mv root/database/ /u01
(7) 更改u01组属
[root@dg2 /]# chown -R oracle:oinstall u01
(8) 检查oracle所需包
包清单如下:
binutils-2.17.50.0.6
compat-libstdc++-33-3.2.3
elfutils-libelf-0.125
elfutils-libelf-devel-0.125

安装缺省包
[root@dg2 package]# rpm -ivh *.rpm
(9) 设定内核参数
a. [root@dg2 package]# vi /etc/security/limits.conf
oracle soft nproc 2047
oracle hard nproc 16384
oracle soft nofile 1024
oracle hard nofile 65536
oracle hard stack 10240
b. [root@dg2 package]# vi /etc/sysctl.conf
fs.aio-max-nr = 1048576
fs.file-max = 6815744
kernel.shmall = 2097152
kernel.shmmax = 2147483648
kernel.shmmni = 4096
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 = 1048576
查看设定的内核参数
[root@dg2 package]# sysctl -p
(10) 安装
[root@dg2 ~]# su - oracle
进入/u01/database
[oracle@dg2 ~]$ cd ..
[oracle@dg2 u01]$ cd database
检查本地VMnet1 的 ipv4地址与DISPLAY环境变量是否一致(输出图形界面)
本地命令: ifconfig /all
[oracle@dg2 database]$ env | grep DIS
DISPLAY=192.168.174.1:0.0
开始安装
[oracle@dg2 database]$ ./runInstaller
如果报ip警告需修改文件 /etc/hosts
[oracle@dg2 database]$ exit
logout
[root@dg2 ~]# vi /etc/hosts
192.168.174.128 dg2
[root@dg2 ~]# ping dg2
ping 通
[root@dg2 ~]# su - oracle
继续安装
忽略Email,next,
减少出错概率,先只安装软件
选择单实例
yes ,next
yes,next,进入检查界面
内存小,忽略,如图缺如下一个包,忽略
next, finish,开始安装
提示执行如下两个文件
另开一个Xshell,进入相应目录,执行以上两个文件,执行完后,点击“OK”按钮,提示安装成功,点击“close”
进入之前的Xshell ,进入oracle目录
[oracle@dg2 ~]$ pwd
/u01/oracle
创建新数据库
[oracle@dg2 ~]$ dbca
next-->next-->next, 因为之前环境变量已配poli
next-->next
选择如下字符集,支持中文
ok,开始创建
漫长等待之后,安装完成,exit
查询安装文件
[oracle@dg2 ~]$ ps -ef | grep oracle
哇塞,安装成功,小激动一下,感谢小布老师的视频

The steps for upgrading MySQL database include: 1. Backup the database, 2. Stop the current MySQL service, 3. Install the new version of MySQL, 4. Start the new version of MySQL service, 5. Recover the database. Compatibility issues are required during the upgrade process, and advanced tools such as PerconaToolkit can be used for testing and optimization.

MySQL backup policies include logical backup, physical backup, incremental backup, replication-based backup, and cloud backup. 1. Logical backup uses mysqldump to export database structure and data, which is suitable for small databases and version migrations. 2. Physical backups are fast and comprehensive by copying data files, but require database consistency. 3. Incremental backup uses binary logging to record changes, which is suitable for large databases. 4. Replication-based backup reduces the impact on the production system by backing up from the server. 5. Cloud backups such as AmazonRDS provide automation solutions, but costs and control need to be considered. When selecting a policy, database size, downtime tolerance, recovery time, and recovery point goals should be considered.

Optimizing database schema design in MySQL can improve performance through the following steps: 1. Index optimization: Create indexes on common query columns, balancing the overhead of query and inserting updates. 2. Table structure optimization: Reduce data redundancy through normalization or anti-normalization and improve access efficiency. 3. Data type selection: Use appropriate data types, such as INT instead of VARCHAR, to reduce storage space. 4. Partitioning and sub-table: For large data volumes, use partitioning and sub-table to disperse data to improve query and maintenance efficiency.

MySQL functions can be used for data processing and calculation. 1. Basic usage includes string processing, date calculation and mathematical operations. 2. Advanced usage involves combining multiple functions to implement complex operations. 3. Performance optimization requires avoiding the use of functions in the WHERE clause and using GROUPBY and temporary tables.

Efficient methods for batch inserting data in MySQL include: 1. Using INSERTINTO...VALUES syntax, 2. Using LOADDATAINFILE command, 3. Using transaction processing, 4. Adjust batch size, 5. Disable indexing, 6. Using INSERTIGNORE or INSERT...ONDUPLICATEKEYUPDATE, these methods can significantly improve database operation efficiency.

In MySQL, add fields using ALTERTABLEtable_nameADDCOLUMNnew_columnVARCHAR(255)AFTERexisting_column, delete fields using ALTERTABLEtable_nameDROPCOLUMNcolumn_to_drop. When adding fields, you need to specify a location to optimize query performance and data structure; before deleting fields, you need to confirm that the operation is irreversible; modifying table structure using online DDL, backup data, test environment, and low-load time periods is performance optimization and best practice.
