MySQL衍生版 Percona Server的更多资料请搜索~ 对于如今mysql在甲骨文的掌控下，最为开源软件来说前景堪忧~ mysql的衍生版倒是有几个，这些东西到底能不能用？ 红薯都用percona作为oschina的生产数据库了。我也不怕了！哈哈，上！坚决的上！因为我是先拿vps小内存的环境开刀（搞熟悉了上生产线），所以centos6系统为32位滴，那么64位、centos5等等，如法炮制即可~
对?Percona Server?的担忧，使用这个不会出问题吧，是不是和mysql都不一样。不用担心，mysql怎么用你他就怎么用，配置也是一样的。
? ? 安装
对于用源码编译安装，和用rpm安装的利弊，我这样理解。如果你需要进行二次开发、修改、定制化，那么你就选择源码编译安装。如果你就是用用，那么直接yum吧骚年，难道你要rpm一个一个手动安装？ok那也行。
如果你是32位
[root@s1 ~]# rpm -Uhv?http://www.percona.com/redir/downloads/percona-release/percona-release-0.0-1.i386.rpm
如果你是64位
[root@s1 ~]# rpm -Uhv?http://www.percona.com/redir/downloads/percona-release/percona-release-0.0-1.x86_64.rpm
检查下
[root@s1 ~]# yum list |grep percona

这样已经成功了，开始yum吧。里面有很多很多东东呢，还有备份工具什么的。还有不同的版本。选你需要的包。
这里一定要安装 Percona-Server-shared-compat 包，否则会报错的。

PLEASE REMEMBER TO SET A PASSWORD FOR THE MySQL root USER !
To do so, start the server, then issue the following commands:
/usr/bin/mysqladmin -u root password ‘new-password’
/usr/bin/mysqladmin -u root -h s1.us.iamle.com password ‘new-password’
Alternatively you can run:
/usr/bin/mysql_secure_installation
which will also give you the option of removing the test
databases and anonymous user created by default. This is
strongly recommended for production servers.
See the manual for more instructions.
Please report any problems with the /usr/bin/mysqlbug script!
Percona recommends that all production deployments be protected with a support
contract (http://www.percona.com/mysql-suppport/) to ensure the highest uptime,
be eligible for hot fixes, and boost your team’s productivity.
Percona Server is distributed with several useful UDF (User Defined Function) from Maatkit.
Run the following commands to create these functions:
mysql -e “CREATE FUNCTION fnv1a_64 RETURNS INTEGER SONAME ‘libfnv1a_udf.so’”
mysql -e “CREATE FUNCTION fnv_64 RETURNS INTEGER SONAME ‘libfnv_udf.so’”
mysql -e “CREATE FUNCTION murmur_hash RETURNS INTEGER SONAME ‘libmurmur_udf.so’”

到这里就已经成功了。
启动
/etc/init.d/mysql start
初始root密码为空，执行mysql_secure_installation进行初始化root操作·
mysql_secure_installation
设置root密码
/usr/bin/mysqladmin -u root password ‘new-password’
或者
/usr/bin/mysqladmin -u root -h s1.us.iamle.com password ‘new-password’
设置msyql安全，去掉远程登录等。密码为刚刚设置的密码。
/usr/bin/mysql_secure_installation
? ??Percona(mysql)配置文件
? ? ?my.cnf
可以通过percona官网在线生成percona(mysql) 配置文件my.cnf?https://tools.percona.com/?。强烈推荐，简单、快捷、可靠。 percona通过yum安装的rpm包默认没有my.cnf文件在 /etc/my.cnf 。vi /etc/my.cnf 加入生成的配置即可。 数据库默认路径 /var/lib/mysql/ 。
ps：如果你在配置文件中改变了/var/lib/mysql/路径，请mv过去。搞错data目录是无法启动的。
会报错
[root@s1 mysql]# /etc/init.d/mysql start
Starting MySQL (Percona Server)… ERROR! The server quit without updating PID file (/home/mysql/data//s1.us.iamle.com.pid).
? ??默认字符集
二进制安装的percona默认的字符集为latin1 ，这里我们需要为utf8，percona官网生产的配置文件没有指定字符集的，需要自己手动配置到my.cnf文件中。
# CLIENT #
#修改客户端默认字符编码格式为utf8
default-character-set=utf8
# GENERAL #
#修改服务器端默认字符编码格式为utf8
character_set_server=utf8
#重启mysql后在查询中查看当前字符集~
show variables like ‘character%’;
show variables like ‘collation%’;
#查看所有字符集
show character set;
如果以上都做了，数据库也设置为utf8了，但是还是会乱码。
那么直接在SQL文件的最前面加上：
SET NAMES ‘utf8′;
它相当于下面的三句指令：
SET character_set_client = utf8;
SET character_set_results = utf8;
SET character_set_connection = utf8;
? ??启动 percona(mysql)
和mysql完全一样,停止和重启也如法炮制
service mysql start
或者
/etc/init.d/mysql start

May 10, 2024 am 01:54 AM
Oracle database and MySQL are both databases based on the relational model, but Oracle is superior in terms of compatibility, scalability, data types and security; while MySQL focuses on speed and flexibility and is more suitable for small to medium-sized data sets. . ① Oracle provides a wide range of data types, ② provides advanced security features, ③ is suitable for enterprise-level applications; ① MySQL supports NoSQL data types, ② has fewer security measures, and ③ is suitable for small to medium-sized applications.
How to delete data from MySQL table using PHP?
Jun 05, 2024 pm 12:40 PM
PHP provides the following methods to delete data in MySQL tables: DELETE statement: used to delete rows matching conditions from the table. TRUNCATETABLE statement: used to clear all data in the table, including auto-incremented IDs. Practical case: You can delete users from the database using HTML forms and PHP code. The form submits the user ID, and the PHP code uses the DELETE statement to delete the record matching the ID from the users table.
