Xcache是一个使用比较多的Opcode缓存器,很多时候,我们为了让脚本的执行效率更加高,可以采取这种缓存器,它可以让脚本引擎不用每次都去编译执行,可以在一次编译后,把Opcode缓存起来,直接去执行,效率会提升30%-40%左右,当PHP文件被更改过以后,Xcache会自动讲该文件的缓存,从Opcode管理器中踢出,执行到该文件时,重新进行缓存,之前写过如何在Centos上部署安装Xcache。
在部署好以后,我们如何进一步去查看它的工作状态,是否为我们提升了效率呢,缓存命中率是多少呢,为它分配的内存占比达到了多少呢,需要清除某一个文件的缓存,该如何操作?
找到xcache的安装目录,把xcache下的htdocs目录,拷贝到网站根目录,重新命名,使用网址去访问,即可。
cp -a ./xcache-3.1.0/htdocs/ /usr/local/nginx/html/opcache
打开php.ini文件,配置好用户名和密码。
[xcache.admin]
xcache.admin.auth = On
xcache.admin.user = "mingkrcom"
; xcache.admin.pass = md5($your_password) 密码配置必须是MD5加密后的字符串
xcache.admin.pass = "ce9fc7cbd0f755edg293eh7ga0781f1"
如果在安装时,配置过了,不用重复添加。
可以看到分配的内存是128M,缓存占比剩下52.63M,以及命中率等参数。
以及诊断结果页面,看到了xcache针对你的服务器给出的建议。
PHP文件的缓存,显示了文件路径地址,可以看到文件的命中率,以及缓存大小。
也可以看到使用Xcache进行的变量缓存数据,建议不要使用xcache来缓存变量,如果要缓存变量,建议使用Memcache或者redis。
PHP脚本,建议安装一下该平台,可以实时查看缓存数据。

MySQL partitioning improves performance and simplifies maintenance. 1) Divide large tables into small pieces by specific criteria (such as date ranges), 2) physically divide data into independent files, 3) MySQL can focus on related partitions when querying, 4) Query optimizer can skip unrelated partitions, 5) Choosing the right partition strategy and maintaining it regularly is key.

How to grant and revoke permissions in MySQL? 1. Use the GRANT statement to grant permissions, such as GRANTALLPRIVILEGESONdatabase_name.TO'username'@'host'; 2. Use the REVOKE statement to revoke permissions, such as REVOKEALLPRIVILEGESONdatabase_name.FROM'username'@'host' to ensure timely communication of permission changes.

InnoDB is suitable for applications that require transaction support and high concurrency, while MyISAM is suitable for applications that require more reads and less writes. 1.InnoDB supports transaction and bank-level locks, suitable for e-commerce and banking systems. 2.MyISAM provides fast read and indexing, suitable for blogging and content management systems.

There are four main JOIN types in MySQL: INNERJOIN, LEFTJOIN, RIGHTJOIN and FULLOUTERJOIN. 1.INNERJOIN returns all rows in the two tables that meet the JOIN conditions. 2.LEFTJOIN returns all rows in the left table, even if there are no matching rows in the right table. 3. RIGHTJOIN is contrary to LEFTJOIN and returns all rows in the right table. 4.FULLOUTERJOIN returns all rows in the two tables that meet or do not meet JOIN conditions.

Common security vulnerabilities in MySQL include SQL injection, weak passwords, improper permission configuration, and unupdated software. 1. SQL injection can be prevented by using preprocessing statements. 2. Weak passwords can be avoided by forcibly using strong password strategies. 3. Improper permission configuration can be resolved through regular review and adjustment of user permissions. 4. Unupdated software can be patched by regularly checking and updating the MySQL version.

Identifying slow queries in MySQL can be achieved by enabling slow query logs and setting thresholds. 1. Enable slow query logs and set thresholds. 2. View and analyze slow query log files, and use tools such as mysqldumpslow or pt-query-digest for in-depth analysis. 3. Optimizing slow queries can be achieved through index optimization, query rewriting and avoiding the use of SELECT*.
