作者: admin 时间: 2021-7-3 09:06 标题: Discuz!X2.5+Redis+Memcached

笺注：这是在 CentOS8_lnmp1.7_LNMP 的基础上进行的。 Redis是一个基于内存、键值对的开源存储数据库；在内存中存储数据，防止高并发影响数据库性能，减少数据库压力，提高查询速度。 Discuz!X2.5使用Redis 管理中心》全局》性能优化》内存优化：图片1.png

注释：默认情况下，Redis是需要额外安装的。下载Redis的软件包：（可实现离线安装） http://download.redis.io/releases/redis-6.0.8.tar.gz http://pecl.php.net/get/redis-5.3.2.tgz 上传Redis的软件包： [root@centos8 src]# pwd /root/lnmp1.7-full/src [root@centos8 src]# ll redis-* -rw-r--r-- 1 root root 266814 7月 2 09:14 redis-5.3.2.tgz -rw-r--r-- 1 root root 2247528 3月 3 18:40 redis-6.0.8.tar.gz 安装Redis： [root@centos8 ~]# cd lnmp1.7-full [root@centos8 lnmp1.7-full]# ./addons.sh 图片2.png

安装或取消安装：

Redis安装成功：图片4.png

重启Redis： [root@centos8 ~]# systemctl restart redis Redis会随系统的启动而启动： [root@centos8 ~]# systemctl is-enabled redis enabled 查询Redis的配置文件： [root@centos8 ~]# php -i |grep redis Additional .ini files parsed => /usr/local/php/conf.d/007-redis.ini redis redis.arrays.algorithm => no value => no value redis.arrays.auth => no value => no value redis.arrays.autorehash => 0 => 0 redis.arrays.connecttimeout => 0 => 0 redis.arrays.consistent => 0 => 0 redis.arrays.distributor => no value => no value redis.arrays.functions => no value => no value redis.arrays.hosts => no value => no value redis.arrays.index => 0 => 0 redis.arrays.lazyconnect => 0 => 0 redis.arrays.names => no value => no value redis.arrays.pconnect => 0 => 0 redis.arrays.previous => no value => no value redis.arrays.readtimeout => 0 => 0 redis.arrays.retryinterval => 0 => 0 redis.clusters.auth => no value => no value redis.clusters.cache_slots => 0 => 0 redis.clusters.persistent => 0 => 0 redis.clusters.read_timeout => 0 => 0 redis.clusters.seeds => no value => no value redis.clusters.timeout => 0 => 0 redis.pconnect.connection_limit => 0 => 0 redis.pconnect.echo_check_liveness => 1 => 1 redis.pconnect.pool_pattern => no value => no value redis.pconnect.pooling_enabled => 1 => 1 redis.session.lock_expire => 0 => 0 redis.session.lock_retries => 10 => 10 redis.session.lock_wait_time => 2000 => 2000 redis.session.locking_enabled => 0 => 0 Registered save handlers => files user redis rediscluster This program is free software; you can redistribute it and/or modify Redis的配置文件： [root@centos8 ~]# cat /usr/local/php/conf.d/007-redis.ini extension = "redis.so" 在PHP测试页可以看到Redis的信息：图片5.png

现在Discuz!X2.5支持Redis了，但还要在Discuz!X2.5的全局配置文件config_global.php中打开：图片6.png

去到Discuz!X2.5的站点目录里修改config_global.php：图片7.png

[root@centos8 config]# vi config_global.php 图片8.png

修改为： $_config['memory']['redis']['server'] = '127.0.0.1'; 图片9.png

注释：修改完成后，保存文件即可生效。 Redis生效了：图片10.png

笺注： Redis开启后，不会使数据的更新发生延迟。对Redis进行内存清理：（点击“内存清理”即可）图片11.png

###### Memcached 是一个高性能的分布式内存对象缓存系统，用于动态Web应用以减轻数据库负载。它通过在内存中缓存数据和对象来减少读取数据库的次数，从而提高数据库的访问速度。安装Memcached的扩展php-memcache：下载Memcached的软件包：（可实现离线安装） https://soft.vpser.net/web/memcache/memcache-4.0.5.2.tgz https://soft.vpser.net/web/memcached/memcached-1.6.7.tar.gz 先上传Memcached的相关软件包： [root@centos8 src]# pwd /root/lnmp1.7-full/src [root@centos8 src]# ll memcache* -rw-r--r-- 1 root root 75061 7月 2 10:09 memcache-4.0.5.2.tgz -rw-r--r-- 1 root root 547791 3月 3 18:42 memcached-1.6.7.tar.gz [root@centos8 ~]# cd lnmp1.7-full [root@centos8 lnmp1.7-full]# bash addons.sh install memcached 图片13.png

注释： Memcached有两个PHP扩展，分别是php-memcache和php-memcached；根据实际需求选择php-memcache或php-memcached，discuz x使用的是php-memcache；功能上php-memcached更强大一些；安装或取消安装：图片14.png

Memcached的扩展php-memcache安装成功：图片15.png

现在Discuz!X2.5支持php-memcache了，但还要在Discuz!X2.5的全局配置文件config_global.php中打开：图片17.png

去到Discuz!X2.5的站点目录里修改config_global.php：图片18.png

[root@centos8 config]# vi config_global.php 修改为： $_config['memory']['memcache']['server'] = '127.0.0.1'; 图片19.png

注释：在discuz!中打开Memcached的扩展php-memcache 在discuz!中关闭Redis 修改完成后，保存文件即可生效。 php-memcache生效了：图片20.png

笺注：打开php-memcache后，不会使数据的更新发生延迟。 ###### 卸载Memcached： [root@centos8 ~]# cd lnmp1.7-full [root@centos8 lnmp1.7-full]# ./addons.sh uninstall memcached 图片21.png
