1，首先建立Informix组和Informix用户使用root用户将Informix安装文件传入Linux使用root用户将Informix安装在/bank/informi目录下
1，首先建立Informix组和Informix用户
使用root用户将Informix安装文件传入Linux
使用root用户将Informix安装在/bank/informi目录下
2，安装好后用Informix进去设置
修改/bank/informix/.bash_profile文件
在/bank/informix/etc/目录下增加文件onconfig.cmsserver
在/bank/informix/etc/目录下增加文件sqlhosts
修改/etc/services文件
在/bank/informix/目录下新建2个文件夹data和log，并在data目录增加表空间rootdbs，tmpdbs，cifdbs，cmsdbs，migdbs;tmp目录增加表空间tmpdbs。先touch再chmod为660
然后使用onmonitor命令初始化设置Parameters-->Initialize
注意最后一页的最后一项修改为空
(可以省略下面的测试
使用命令oninit测试是否成功启动
使用命令onmode –ky测试是否成功关闭)
3，创建数据库空间
数据库没有启动时执行
$onspaces -c -d cifdbs -p "/bank/informix/data/cifdbs" -o 100 -s 512000
$onspaces -c -d migdbs -p "/bank/informix/data/migdbs" -o 100 -s 1024000
$onspaces -c -d cmsdbs -p "/bank/informix/data/cmsdbs" -o 100 -s 1024000
$onspaces -c -d tmpdbs -t-p "/bank/informix/data/tmpdbs" -o 100 -s 512000
$ontape -s -L 0 （0级备份）
4，，导入表结构和表数据
需要启动数据库之后
dbimport -q -c -d migdbs migdbs
./loadcmsdbs.sh /bank/informi/dataFrom2242 在目录/bank/informi/dataFrom2242下放着cmsdbs.exp文件
5，root新建一个用户a，informix用户进去为a赋权限grant dba to a
然后就可以使用终端访问了。
MySQL: Essential Skills for Beginners to MasterApr 18, 2025 am 12:24 AMMySQL is suitable for beginners to learn database skills. 1. Install MySQL server and client tools. 2. Understand basic SQL queries, such as SELECT. 3. Master data operations: create tables, insert, update, and delete data. 4. Learn advanced skills: subquery and window functions. 5.

MySQL: Structured Data and Relational DatabasesApr 18, 2025 am 12:22 AMMySQL efficiently manages structured data through table structure and SQL query, and implements inter-table relationships through foreign keys. 1. Define the data format and type when creating a table. 2. Use foreign keys to establish relationships between tables. 3. Improve performance through indexing and query optimization. 4. Regularly backup and monitor databases to ensure data security and performance optimization.
MySQL: Key Features and Capabilities ExplainedApr 18, 2025 am 12:17 AMMySQL is an open source relational database management system that is widely used in Web development. Its key features include: 1. Supports multiple storage engines, such as InnoDB and MyISAM, suitable for different scenarios; 2. Provides master-slave replication functions to facilitate load balancing and data backup; 3. Improve query efficiency through query optimization and index use.
The Purpose of SQL: Interacting with MySQL DatabasesApr 18, 2025 am 12:12 AMSQL is used to interact with MySQL database to realize data addition, deletion, modification, inspection and database design. 1) SQL performs data operations through SELECT, INSERT, UPDATE, DELETE statements; 2) Use CREATE, ALTER, DROP statements for database design and management; 3) Complex queries and data analysis are implemented through SQL to improve business decision-making efficiency.
MySQL for Beginners: Getting Started with Database ManagementApr 18, 2025 am 12:10 AMThe basic operations of MySQL include creating databases, tables, and using SQL to perform CRUD operations on data. 1. Create a database: CREATEDATABASEmy_first_db; 2. Create a table: CREATETABLEbooks(idINTAUTO_INCREMENTPRIMARYKEY, titleVARCHAR(100)NOTNULL, authorVARCHAR(100)NOTNULL, published_yearINT); 3. Insert data: INSERTINTObooks(title, author, published_year)VA
MySQL's Role: Databases in Web ApplicationsApr 17, 2025 am 12:23 AMThe 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.
MySQL: Building Your First DatabaseApr 17, 2025 am 12:22 AMThe 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: A Beginner-Friendly Approach to Data StorageApr 17, 2025 am 12:21 AMMySQL 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.
