CentOS

卸载mysql

1、查看安装包 rpm -aq |grep mysql

2、开始卸载

yum remove Mysql*****

一个一个卸载

安装mysql 

1、复制安装包到机器上

2、rpm -ivh Mysql-server***

3、rpm -ivh Mysql-client***

4、启动mysql service mysql start

5、登录mysql -uroot -p

6、成功后退出 exit

7、停止服务 service mysql stop

8、拷贝my.conf 到 /etc/my.conf

9、更改my.conf vi /etc/my.conf 配置一些参数,包括存储位置(存储位置新建的目录需要修改权限给指定的用户组和用户 chown -R mysql:mysql 修改的目录)

10、更改存储位置的时候 需要格式化硬盘

11、fdisk -l 查看未格式化的磁盘如 /dev/xvdd

12、格式化 fdisk /dev/xvdd

13、一次输入 n p 1 一直回车 然后 w(保存)

14、格式化分区 mkfs.ext3 /dev/xvdd1

15、完成后挂接到 /data

16、设置my.conf中的存储位置

17、完成后更改权限chown mysql:mysql *启动mysql

18、确认启动成功

19、执行/usr/local/mysql/bin/mysql_install_db --datadir=/opt/mysql/data --user=mysql

20、一般来说修改之后 使用 service mysql start 是启动不了了 要采用 /usr/bin/mysqld_safe &


注:

1、jdk的可执行权限要配置 chown -R mysql:mysql 修改的目录

2、挂载硬盘 需要写到/etc/fstab文件中/dev/xvdd1 /mnt/nfs ext3 defaults 1 1

3、设置环境变量

export JAVA_HOME=/usr/java/jdk1.6.0_29

export PATH=$PATH:$JAVA_HOME/bin

4、更改jvm参数,修改catalina.sh文件229行添加JAVA_OPTS="$JAVA_OPTS -server -Xms20480M -Xmx20480M -Xmn7680M -Xss20480k -XX:PermSize=1280M -XX:MaxPermSize=4096m -XX:+AggressiveOpts -XX:+UseParallelGC  -XX:+UseBiasedLocking"

5、采用nfs作为文件服务器的,需要配置/etc/fstab,添加行 IP:/mnt/nfs /usr/java/apache-tomcat-6.0.35/webapps/ROOT/uploads nfs nodev,rw,rsize=32768,wsize=32768 0 0

When might a full table scan be faster than using an index in MySQL? When might a full table scan be faster than using an index in MySQL? Apr 09, 2025 am 12:05 AM

Full table scanning may be faster in MySQL than using indexes. Specific cases include: 1) the data volume is small; 2) when the query returns a large amount of data; 3) when the index column is not highly selective; 4) when the complex query. By analyzing query plans, optimizing indexes, avoiding over-index and regularly maintaining tables, you can make the best choices in practical applications.

Explain InnoDB Full-Text Search capabilities. Explain InnoDB Full-Text Search capabilities. Apr 02, 2025 pm 06:09 PM

InnoDB's full-text search capabilities are very powerful, which can significantly improve database query efficiency and ability to process large amounts of text data. 1) InnoDB implements full-text search through inverted indexing, supporting basic and advanced search queries. 2) Use MATCH and AGAINST keywords to search, support Boolean mode and phrase search. 3) Optimization methods include using word segmentation technology, periodic rebuilding of indexes and adjusting cache size to improve performance and accuracy.

Difference between clustered index and non-clustered index (secondary index) in InnoDB. Difference between clustered index and non-clustered index (secondary index) in InnoDB. Apr 02, 2025 pm 06:25 PM

The difference between clustered index and non-clustered index is: 1. Clustered index stores data rows in the index structure, which is suitable for querying by primary key and range. 2. The non-clustered index stores index key values ​​and pointers to data rows, and is suitable for non-primary key column queries.

Can mysql and mariadb coexist Can mysql and mariadb coexist Apr 08, 2025 pm 02:27 PM

MySQL and MariaDB can coexist, but need to be configured with caution. The key is to allocate different port numbers and data directories to each database, and adjust parameters such as memory allocation and cache size. Connection pooling, application configuration, and version differences also need to be considered and need to be carefully tested and planned to avoid pitfalls. Running two databases simultaneously can cause performance problems in situations where resources are limited.

Explain different types of MySQL indexes (B-Tree, Hash, Full-text, Spatial). Explain different types of MySQL indexes (B-Tree, Hash, Full-text, Spatial). Apr 02, 2025 pm 07:05 PM

MySQL supports four index types: B-Tree, Hash, Full-text, and Spatial. 1.B-Tree index is suitable for equal value search, range query and sorting. 2. Hash index is suitable for equal value searches, but does not support range query and sorting. 3. Full-text index is used for full-text search and is suitable for processing large amounts of text data. 4. Spatial index is used for geospatial data query and is suitable for GIS applications.
