centos 7 memcache centos7.5安装

其实centos 7 memcache的问题并不复杂,但是又很多的朋友都不太了解centos7.5安装,因此呢,今天小编就来为大家分享centos 7 memcache的一些知识,希望可以帮助到大家,下面我们一起来看看这个问题的分析吧!

阿里云上的centos 7.2怎么yum安装php 5.6

因之前通过网易的 centos镜像,将阿里云的 centos升级到最新版了,乘自己的项目尚未开始正式开发,遂将所有的相应环境都升级到最高。

查看 centos版本:

[root@iZ23d~]# cat/etc/centos-release

CentOS Linux release 7.2.1511(Core)

1、删除之前的 php版本:

[root@iZ23d~]# yum remove php* php-common

Loaded plugins: langpacks

Repository base is listed more than once in the configuration

Repository updates is listed more than once in the configuration

Repository extras is listed more than once in the configuration

Repository centosplus is listed more than once in the configuration

No Match for argument: php-5.4.16

No Match for argument: php-5.4.16.tar.gz

No Match for argument: php-7.0.1RC1

No Match for argument: php-7.0.1RC1.tar.gz

No Match for argument: phpMyAdmin-4.4.0.tar.gz

No Match for argument: php-common

No Packages marked for removal

2、rpm安装 Php7相应的 yum源:

[root@iZ23d~]# rpm-Uvh

package webtatic-release-7-3.noarch is already installed

3、直接yum安装php7:

[root@iZ23d~]# yum install php70w

Loaded plugins: langpacks

Repository base is listed more than once in the configuration

Repository updates is listed more than once in the configuration

Repository extras is listed more than once in the configuration

4、检查 php版本:

[root@iZ23d~]# php-v

[root@iZ23d2e6hoqZ~]#

以上显示安装成功!

5、重启 Apache,查看 phpinfo:

[root@iZ23d~]# systemctl restart httpd.service

检查phpinfo:

LAMP平台安装Xcache和Memcached加速网站运行

在CentOS 7系统里搭建好LAMP环境后,就可以安装网站程序了,以最流行了Wordpess为例。为了加快网站的访问速度,除了花钱买更好的硬件设施外。我们可以通过优化网站的程序、主题。为服务器开启缓存功能,为网站提速。我们知道,互联网上缓存为王。

1.安装php加速器Xcache

XCache是一个国人开发的又快又稳定的 PHP opcode缓存器,通过共享编译内存从而降低服务器负载。

由于yum源仓库里面没有,先下载源文件,最新版3.2.0

在tmp目录下:cd/tmp下载:wget

解压缩:tar xvfz xcache-3.2.0.tar.gz

准备安装:cd xcache-3.2.0

安装前,先要准备编译环境:yum-y install php-devel gcc

运行phpize,非常重要:phpize

配置:./configure--enable-xcache

安装:make make install

复制配置文件 cp xcache.ini/etc/php.d(xcache.ini在源程序安装目录)

重新启动http服务:systemctl restart httpd

2.安装memcached

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,从而提供动态、数据库驱动网站的速度。

a.安装

yum-y install memcached

安装memcache关联php

yum-y install php-pecl-memcache

编译安装PHP的memcache扩展

下载 wget

tar xf memcache-3.0.8.tgz

cd memcache-3.0.8

依次执行

phpize

./configure

make make install

b.配置

在php.ini文件中添加memcache扩展

extension=/usr/lib64/php/modules/memcache.so(版本不同目录可能不同)

c.运行

memcached-d-m 128-c 1024-P/tmp/memcached.pid

d.测试

测试memcached是否工作正常,在网站目录下编辑一个文件如memtest.php,放入如下代码:

$memcache= new Memcache;

$memcache-connect('localhost', 11211) or die("Could not connect");

$version=$memcache-getVersion();

echo"Server's version:".$version."

/n";

$tmp_object= new stdClass;

$tmp_object-str_attr='test';

$tmp_object-int_attr= 123;

$memcache-set('key',$tmp_object, false, 10) or die("Failed to save data at the server");

echo"Store data in the cache(data will expire in 10 seconds)

/n";

$get_result=$memcache-get('key');

echo"Data from the cache:

/n";

var_dump($get_result);

?

访问后如果能现实版本号server's version: 1.4…… store date in the cache等信息说明memcached运行正常。

5.整合

Wordpress支持memcached

下载:wget

unzip memcached.2.0.2.zip

cd memcached.2.0.2

复制 object-cache.php到网站根目录 wp-content文件夹内,wordpress会自动调用缓存。

重启服务器:

sytemctl restart memcached

sytemctl restart httpd

3.开启Gzip压缩。

apache2.4版本默认添加了gzip模块,我们要同时开启deflate模块,压缩网页文件,提高服务器浏览速度。

vim/etc/httpd/conf/httpd.conf在最后加入如下几行:

DeflateCompressionLevel 9

AddOutputFilterByType DEFLATE text/html text/plain text/xml application/x-httpd-php

AddOutputFilter DEFLATE css js

重新启动http服务:systemctl restart httpd

怎么将python脚本 部署到虚拟centos7上去

1.安装centos VMware9下面安装centos2.在centos下面设置共享文件夹为你本地的论坛的代码,然后设置网络为桥接:直接连接到物理网络,赋值网络连接状态3.进入forum_svr.py目录下运行python forum_svr.py,当然是启动不了服务的4.安装easy_install(想办法)5.安装pymogo tornado memcache等一系列的模块。6.当然还是启动不了的7.还需要启动memcached,所以就要安装memcached,Memcached是由Danga Interactive开发的,高性能的,分布式的内存对象缓存系统,用于在动态应用中减少数据库负载,提升访问速度。所以你就要安装libevent8.libevent最新的稳定版:wget

# rpm-q libevent(首先检查系统是否安装了Libevent)

# yum-y install libevent*(我使用的Yum安装)或者可以使用编译安装

# tar zxvf libevent-1.4.14b-stable.tar.gz

# cd libevent-1.4.14b-stable

#./configure--prefix=/usr/local/libevent/# make

# make install

9.memcached最新的稳定版:wget tar-zxvf memcached-1.4.5.tar.gz

# cd memcached-1.4.5#./configure--prefix=/usr/local/memcached--with-libevent=/usr/local/libevent/# make

# make install

启动Memcached

# cd/usr/local/memcached/bin/#./memcached-u root-d

将Memcached加入系统自动启动

# vim/etc/rc.local

#/usr/local/memcached/bin/memcached-u root-d

查看Memcached

# ps-ef|grep memcached

10.然后你就要找到虚拟机的IP地址,可以在虚拟机下找运行ifconfig例如:inet addr:192.168.0.109

11.在course_form_edit.html和course_forum_viem.html下修改swf:地址:(我的)当然是了。(共六处)12.现在从虚拟机下启动forum_svr.py就能启动了。13.可能在windows下你访问时可能还是会报服务器拒绝的错误,说明虚拟机的链接地址还是请求不到虚拟机下的数据,可以在虚拟机下运行

iptables-I INPUT-i eth0-p tcp--dport 8086-j ACCEPT(为windows下实体机开辟一个8086端口),虚拟机防火墙不让请求数据。

OK,现在windows下就可以请求到数据了。方便本地的调试了。
