现在使用Ubuntu的朋友越来越多了,包括我自己也从开始彻底代替了Windows作为我的唯一桌面系统来用,而正和公司是用的Oracle发生了磨合,Oracle在win下有很多辅助工具,而linux~~ 不管他了,装了个Oracle Datebase 10g Express Editon之后Hq居然识别是O9i,郁闷,先装个10G标准版forx86看看吧
1,,环境准备
a,确认你的系统是否符合一下几点
500 MB 内存
1 GB 交换分区
确认你已经安装了gcc, make, binutils, lesstif2, libc6, 和 rpm,另外确认一下libaio包是否安装了。
*最好确认 dns 和/或 你的 /etc/hosts 文件已经正确配置了,以保证你的IP地址和hostname能正确解析。
b,用户建立
我们需要为安装程序创建一个Oracle 用户和两个组. 首先检查它们是否已经存在:
$grep oinstall /etc/group
$grep dba /etc/group
$grep nobody /etc/group
如果它们还不在系统中,那么创建它们。
#addgroup oinstall
#addgroup dba
#addgroup nobody
#useradd -m -g oinstall -G dba -p passwd -d /home/Oracle -s /bin/bash Oracle
#usermod -g nobody nobody
修改相应权限:
#mkdir -p /opt/Oracle
#mkdir -p /opt/oradata
#chown -R Oracle:oinstall /opt/ora*
#chmod -R 775 /opt/ora*
c,系统环境配置
添加以下行到 /etc/sysctl.conf 文件中:
kernel.shmall = 2097152
kernel.shmmax = 2147483648
kernel.shmmni = 4096
kernel.sem = 250 32000 100 128
fs.file-max = 65536
net.ipv4.ip_local_port_range = 1024 65000
更新系统, 运行:
#sysctl -p
添加以下行到 /etc/security/limits.conf 文件中:
* soft nproc 2407
* hard nproc 16384
* soft nofile 1024
* hard nofile 65536
建立软连接:
#ln -s /usr/bin/awk /bin/awk
#ln -s /usr/bin/rpm /bin/rpm
#ln -s /usr/bin/basename /bin/basename
d,建立版本文件
如果不建立版本文件,运行runInstaller,会出现如下错误:
Checking requirements...
Checking operating system version: must be RedHat-2.1,redhat-3,SUSE-9,SuSE-8,UnitedLinux-1.0
Failed /etc/UnitedLinux-release UnitedLinux 1.0 (i586)
>VERSION=1.0
>EOF
然后就可以正常启动安装程序。注意不要使用vi编辑该文件,否则可能会引起ORA-12547: TNS: lost contact的错误。
方法二:
运行runInstaller -ignoreSysPrereqs,这样会跳过检查
方法三:
修改Oracle 的/.../disk1/install/linux/oraparam.ini这个参数文件
2,安装
用Oracle用户登录,将安装文件拷贝到一个临时目录。
运行如下命令:
$./runInstaller
然后会出现图形安装界面,按照需求进行配置安装。安装目录使用上面建立的/opt/Oracle。在安装的最后,会有一个需要手工运行脚本的地方,必须使用root用户。

The main role of MySQL in web applications is to store and manage data. 1.MySQL efficiently processes user information, product catalogs, transaction records and other data. 2. Through SQL query, developers can extract information from the database to generate dynamic content. 3.MySQL works based on the client-server model to ensure acceptable query speed.

The steps to build a MySQL database include: 1. Create a database and table, 2. Insert data, and 3. Conduct queries. First, use the CREATEDATABASE and CREATETABLE statements to create the database and table, then use the INSERTINTO statement to insert the data, and finally use the SELECT statement to query the data.

MySQL is suitable for beginners because it is easy to use and powerful. 1.MySQL is a relational database, and uses SQL for CRUD operations. 2. It is simple to install and requires the root user password to be configured. 3. Use INSERT, UPDATE, DELETE, and SELECT to perform data operations. 4. ORDERBY, WHERE and JOIN can be used for complex queries. 5. Debugging requires checking the syntax and use EXPLAIN to analyze the query. 6. Optimization suggestions include using indexes, choosing the right data type and good programming habits.

MySQL is suitable for beginners because: 1) easy to install and configure, 2) rich learning resources, 3) intuitive SQL syntax, 4) powerful tool support. Nevertheless, beginners need to overcome challenges such as database design, query optimization, security management, and data backup.

ACID attributes include atomicity, consistency, isolation and durability, and are the cornerstone of database design. 1. Atomicity ensures that the transaction is either completely successful or completely failed. 2. Consistency ensures that the database remains consistent before and after a transaction. 3. Isolation ensures that transactions do not interfere with each other. 4. Persistence ensures that data is permanently saved after transaction submission.

MySQL is not only a database management system (DBMS) but also closely related to programming languages. 1) As a DBMS, MySQL is used to store, organize and retrieve data, and optimizing indexes can improve query performance. 2) Combining SQL with programming languages, embedded in Python, using ORM tools such as SQLAlchemy can simplify operations. 3) Performance optimization includes indexing, querying, caching, library and table division and transaction management.

MySQL uses SQL commands to manage data. 1. Basic commands include SELECT, INSERT, UPDATE and DELETE. 2. Advanced usage involves JOIN, subquery and aggregate functions. 3. Common errors include syntax, logic and performance issues. 4. Optimization tips include using indexes, avoiding SELECT* and using LIMIT.
