FreeBSD安装MySQL_MySQL
FreeBSDmysql安装
ports安装:
cd /usr/ports/databases/mysql51-server
make WITH_CHARSET=utf8 WITH_PROC_SCOPE_PTH=yes BUILD_OPTIMIZED=yes BUILD_STATIC=yes SKIP_DNS_CHECK=yes WITHOUT_INNODB=yes install clean
装了N个服务器之后总结出来的,需要注意的几点:
make安装时候的参数
WITH_XCHARSET=all 不加这个的话会不支持GBK编码
BUILD_OPTIMIZED=yes
BUILD_STATIC=yes 这2项都是起到优化作用,都加上的好
mysql默认读取/etc目录下面的my.cnf,但是安装过程不会自动在这目录下创建本文件,默认这个文件在/usr/local/share/mysql目录下面,有3个版本:
my-large.cnf 一般高配置服务器或者mysql专用服务器用这个配置文件
my-medium.cnf 服务器配置并跑有其它应用时用这个配置文件
my-small.cnf 服务器资源紧张的就用这个好了
根据你的机器配置选择一个cp /usr/local/share/mysql/my-large.cnf /etc/my.cnf
安装过程并不会自动创建默认的数据库,需要手工创建
/usr/local/bin/mysql_install_db –user=mysql
并且需要更改数据库目录的权限,不然会启动不起来
chown -R mysql:mysql /var/db/mysql
启动mysql,好像第一次用脚本启动的话要使用
/usr/local/etc/rc.d/mysql-server onestart
使用/usr/local/etc/rc.d/mysql-server start不行
修改root密码,比如我们要修改成123456
mysqladmin -uroot -p password 123456
会提示你再次输入一次密码Enter password:,再输入一次123456即可
修改数据文件的默认目录
vi /etc/my.cnf中加入datadir=数据库的目录,记得把原/var/db/mysql中的文件都复制过去,再执行
chown -R mysql:mysql 数据库的目录
最后一点千万别忘记,要不然mysql又该启动不起来了
修改/usr/local/etc/rc.d/mysql-server文件中的mysql_dbdir=”/var/db/mysql”为你的新目录
或者在/etc/rc.conf中加入mysql_dbdir=”新目录”
最后在/etc/rc.conf加入mysql_enable=”yes”让mysql开机自启动

MySQL is suitable for beginners because it is simple to install, powerful and easy to manage data. 1. Simple installation and configuration, suitable for a variety of operating systems. 2. Support basic operations such as creating databases and tables, inserting, querying, updating and deleting data. 3. Provide advanced functions such as JOIN operations and subqueries. 4. Performance can be improved through indexing, query optimization and table partitioning. 5. Support backup, recovery and security measures to ensure data security and consistency.

Navicat itself does not store the database password, and can only retrieve the encrypted password. Solution: 1. Check the password manager; 2. Check Navicat's "Remember Password" function; 3. Reset the database password; 4. Contact the database administrator.

Create a database using Navicat Premium: Connect to the database server and enter the connection parameters. Right-click on the server and select Create Database. Enter the name of the new database and the specified character set and collation. Connect to the new database and create the table in the Object Browser. Right-click on the table and select Insert Data to insert the data.

MySQL is an open source relational database management system. 1) Create database and tables: Use the CREATEDATABASE and CREATETABLE commands. 2) Basic operations: INSERT, UPDATE, DELETE and SELECT. 3) Advanced operations: JOIN, subquery and transaction processing. 4) Debugging skills: Check syntax, data type and permissions. 5) Optimization suggestions: Use indexes, avoid SELECT* and use transactions.

Navicat for MariaDB cannot view the database password directly because the password is stored in encrypted form. To ensure the database security, there are three ways to reset your password: reset your password through Navicat and set a complex password. View the configuration file (not recommended, high risk). Use system command line tools (not recommended, you need to be proficient in command line tools).

MySQL and SQL are essential skills for developers. 1.MySQL is an open source relational database management system, and SQL is the standard language used to manage and operate databases. 2.MySQL supports multiple storage engines through efficient data storage and retrieval functions, and SQL completes complex data operations through simple statements. 3. Examples of usage include basic queries and advanced queries, such as filtering and sorting by condition. 4. Common errors include syntax errors and performance issues, which can be optimized by checking SQL statements and using EXPLAIN commands. 5. Performance optimization techniques include using indexes, avoiding full table scanning, optimizing JOIN operations and improving code readability.

You can create a new MySQL connection in Navicat by following the steps: Open the application and select New Connection (Ctrl N). Select "MySQL" as the connection type. Enter the hostname/IP address, port, username, and password. (Optional) Configure advanced options. Save the connection and enter the connection name.

Steps to perform SQL in Navicat: Connect to the database. Create a SQL Editor window. Write SQL queries or scripts. Click the Run button to execute a query or script. View the results (if the query is executed).
