默认的版本太低了,手动安装有一些麻烦,想采用Yum安装的可以使用下面的方案:

1.检查当前安装的PHP包
yum list installed | grep php
如果有安装的PHP包,先删除他们
 yum remove php.x86_64 php-cli.x86_64 php-common.x86_64 php-gd.x86_64 php-ldap.x86_64 php-mbstring.x86_64 php-mcrypt.x86_64 php-mysql.x86_64 php-pdo.x86_64
2.Centos 5.X
  rpm -Uvh http://mirror.webtatic.com/yum/el5/latest.rpm
CentOs 6.x
rpm -Uvh http://mirror.webtatic.com/yum/el6/latest.rpm
CentOs 7.X
rpm -Uvh https://mirror.webtatic.com/yum/el7/epel-release.rpm
rpm -Uvh https://mirror.webtatic.com/yum/el7/webtatic-release.rpm
如果想删除上面安装的包,重新安装
rpm -qa | grep webstatic
rpm -e  上面搜索到的包即可

3.运行yum install

  yum install php55w.x86_64 php55w-cli.x86_64 php55w-common.x86_64 php55w-gd.x86_64 php55w-ldap.x86_64 php55w-mbstring.x86_64 php55w-mcrypt.x86_64 php55w-mysql.x86_64 php55w-pdo.x86_64

yum install php56w.x86_64 php56w-cli.x86_64 php56w-common.x86_64 php56w-gd.x86_64 php56w-ldap.x86_64 php56w-mbstring.x86_64 php56w-mcrypt.x86_64 php56w-mysql.x86_64 php56w-pdo.x86_64

注:如果想升级到5.6把上面的55w换成56w就可以了。

yum install php70w.x86_64 php70w-cli.x86_64 php70w-common.x86_64 php70w-gd.x86_64 php70w-ldap.x86_64 php70w-mbstring.x86_64 php70w-mcrypt.x86_64 php70w-mysql.x86_64 php70w-pdo.x86_64
4.安装PHP FPM

yum install php55w-fpm
yum install php56w-fpm
yum install php70w-fpm
注:如果想升级到5.6把上面的55w换成56w就可以了。

PHP遭弃用!Wordpress.com开源并转用Javascript

站长之家(Chianz.com)11月30日消息 据外媒消息称,Wordpress母公司Automattic将完全重写Wordpress.com网站代码,并将此项计划命名为“Calypso”,代码开源并被托管于Github平台。此外,最新的wordpress.com放弃了php,转而启用Javascript,且通过API调用数据。

以下为几个主要更新点:

1、如今的Wordpress.com为一个管理界面,完全独立于Wordpress的核心代码,且与其(wordpress核心代码)的交互方式类似于其他第三方接口、app。通过REST API来获取发布的内容、上传照片等数据。

2、Wordpress.com 不再使用PHP+MySQL的组合模式,而是采用了Javascript语言及API调用模式。也就是说,当你访问wordpress网站时,会触发服务器分发一个几乎完全运行于用户浏览器上的、功能齐全wordpress客户端。

上面所说的WP客户端实际上是一个单页应用(Single Page Application),这样一来就可大大减少用户与界面进行交互时页面加载的次数。此外,它采用的是响应式设计,因而对手机、平板等移动设备也十分友好。

在新版wordpress.com中,用户可以通过Wordpress原有的后台管理系统来维护博客。也可以通过Jetpack插件来管理wordpress站点,Jetpack插件里面还内置了社会化分享,社会化登录和社会化评论的功能。

3、重写后的Wordpress.com是完全开源的,托管于Github上(地址:https://github.com/Automattic/wp-calypso),用户可在遵从GNU GPL(General Public License)规定情况下查看完整代码、重新使用该代码。

除了wordpress.com开源外,wp团队还针对Mac用户推出了一款类似于桌面应用程序的app。这款App简化了用户访问、维护Wordpress.com的工作,后续还将推出Windows和Linux版本。

云计算用一个朋友的话来说:”做云计算最苦逼的就是得时时刻刻为一些可能一辈子都碰不到的事做

好准备。更苦逼的就是刚以为一个问题不会遇到,立刻就发生了。。。“。这个还真的没有办法,

谁让哥我是搞云计算的呢,简单一个虚拟化就搞的你蛋疼,你还能想其它的吗?一直纠结在做虚

拟化使用什么镜像格式,刚刚开始用了raw的file,后来发现LVM的很多特性对于虚拟化还是有比较

理想的能力,而且性能也很不错就用了LVM。后来被VMware骗了跑去搞Esxi接触了VMDK,最近

研究openstack发现了qcow2格式,貌似现在很流行呀。也说不上分析这些镜像格式的能力,就简单

说说自己的一些使用心得。

 

目前主要有那些格式来作为虚拟机的镜像:

raw


(default) the raw format is a plain binary image of the disc image, and is very portable. On filesystems that suppor

t sparse files, images in this format only use the space actually used by the data recorded in them.

老牌的格式了,用一个字来说就是裸,也就是赤裸裸,你随便dd一个file就模拟了一个raw格式的镜

像。由于裸的彻底,性能上来说的话还是不错的。目前来看,KVM和XEN默认的格式好像还是这

个格式。因为其原始,有很多原生的特性,例如直接挂载也是一件简单的事情。
裸的好处还有就是简单,支持转换成其它格式的虚拟机镜像对裸露的它来说还是很简单的(如果

其它格式需要转换,有时候还是需要它做为中间格式),空间使用来看,这个很像磁盘,使用多

少就是多少(du -h看到的大小就是使用大小),但如果你要把整块磁盘都拿走的话得全盘拿了

(copy镜像的时候),会比较消耗网络带宽和I/O。接下来还有个有趣的问题,如果那天你的硬盘

用着用着不够用了,你咋办,在买一块盘。但raw格式的就比较犀利了,可以在原来的盘上追加空间:
dd if=/dev/zero of=zeros.raw bs=1024k count=4096(先创建4G的空间)
cat foresight.img zeros.raw > new-foresight.img(追加到原有的镜像之后)

我们在各种VPS评测博客,以及在一些广告渠道看到各种优惠的VPS的优惠信息都比较心动其价格和配置性能,在选购的时候我们是要参考一些用户的评论以及自己的评价标准。最为实际的在我们卖到或者能得到免费测试机器的时候,可以通过下面简单实用的VPS性能测试方法看看我们即将选择的VPS产品性能如何,如果在自己的可选标准范围之内,那就选择,如果认为不可以,就放弃。

第一,CPU、内存、硬盘检测

cat /proc/cpuinfo (查看CPU信息)
cat /proc/meminfo (查看内存信息)
df -lh (查看硬盘信息)

这个命令可以看到我们购买的VPS CPU信息是否与官方标准一样,有些时候告诉我们的与实际检测的不同。

第二,硬盘IO性能测试

dd if=/dev/zero of=test bs=64k count=4k oflag=dsync
dd if=/dev/zero of=test bs=8k count=256k conv=fdatasync

在"VPS性能测试工具之三: dd硬盘读写命令"有详细介绍这个命令的使用及具体的性能对比。

第三,UB跑分测试

在"VPS性能测试工具之二: UnixBench"有介绍到UB跑分测试的方法,可以根据自己的跑分测试性能,如果低于100分的直接不考虑,一般肯定会在400分左右。

第四,WGET下载测试

wget http://cachefly.cachefly.net/100mb.test

测试下载速度。

第五,PING及TOP测试

我们在拿到VPS的IP之后,可以用第三方的PING工具进行PING测试速度,或者在我们本地机器上PING测试,可以反应器机器的速度,如果我们做中文站点,一般PING在250之内可以接受的,也有些机器PING速度比较高,但是打开速度还不错。所以说PING只能是参考。

我们还可以用top命令来测试CPU占用情况(扩展阅读:检测MySQL负载过高及解决方法(详解SSH TOP命令))

总之,通过上述的5个方法及参考命令基本上可以测试到这款机器的性能对比。

(3) 关闭yum fastestmirror 功能
shell> vi /etc/yum/pluginconf.d/fastestmirror.conf

enabled=0

介于机房不提供用户流量查询服务,故自行安装。

yum install mysql mysql-server php php-mysql zlib libpng freetype libjpeg fontconfig gd libxml2 rrdtool net-snmp net-snmp-utils net-snmp-devel cacti

 

以上便于记录

yum -y install wget --noplugins
wget freevps.us/downloads/nginx-centos-6.sh -O - | bash

注意安装完成后 php-fpm 默认跑在 apache 用户上。

安装完成后,如果你需要的 PHP 扩展未安装,可输入如下命令查询:

yum list | grep ^php*

找到了扩展的名字,就可以直接安装了:

# 以 php memcache 扩展为例
yum install -y php-pecl-memcached

此外还遇到的问题是 DOMDocument 找不到,直接 yum 安装 php-xml:

yum install -y php-xml

所有扩展 yum 安装完成后都需要重新启动 / 载入 php-fpm。

; - create a graph of FPM availability (rrd or such);
; - remove a server from a group if it is not responding (load balancing);
; - trigger alerts for the operating team (24/7).
; Note: The value must start with a leading slash (/). The value can be

; Possible Values: 'unlimited' or an integer greater or equal to 0
; Default Value: system defined value
;rlimit_core = 0

; Chroot to this directory at the start. This value must be defined as an
; absolute path. When this value is not set, chroot is not used.
; Note: chrooting is a great security feature and should be used whenever 
;       possible. However, all PHP paths will be relative to the chroot
;       (error_log, sessions.save_path, ...).
; Default Value: not set
;chroot = 

; Chdir to this directory at the start. This value must be an absolute path.
; Default Value: current directory or / when chroot

;env[TMP] = /tmp
;env[TMPDIR] = /tmp
;env[TEMP] = /tmp

; Additional php.ini defines, specific to this pool of workers. These settings
; overwrite the values previously defined in the php.ini. The directives are the
; same as the PHP SAPI:
;   php_value/php_flag             - you can set classic ini defines which can
;                                    be overwritten from PHP call 'ini_set'. 
;   php_admin_value/php_admin_flag - these directives won't be overwritten by
;                                     PHP call 'ini_set'
; For php_*flag, valid values are on, off, 1, 0, true, false, yes or no.

; Defining 'extension' will load the corresponding shared extension from
; extension_dir. Defining 'disable_functions' or 'disable_classes' will not
; overwrite previously defined php.ini values, but will append the new value
; instead.

; Default Value: nothing is defined by default except the values in php.ini and
;                specified at startup with the -d argument
;php_admin_value[sendmail_path] = /usr/sbin/sendmail -t -i -f www@my.domain.com

nginx: configuration file /opt/nginx/conf/nginx.conf test is successful

输入代码运行nginx服务

./sbin/nginx

ps au|grep nginx

如果显以类似下面的信息,即表示nginx已经启动

root 2013 0.0 0.0 103156 856 pts/0 S+ 03:22 0:00 grep nginx

输入代码检测是否支持加速

lsof -n | grep tcmalloc

如果显示类似下面的信息,即表示支持tcmalloc加速 (mysqld和nginx两个线程都支持)

mysqld 20818 mysql mem REG 253,0 2177570 281050 /usr/local/lib/libtcmalloc.so.0.2.2

nginx 29454 www 25w REG 253,0 0 288399 /tmp/tcmalloc/.29454

转:http://www.myhack58.com/Article/sort099/sort0102/2011/29472.htm

一、更改yum源为网易的源加快速度

vi /etc/yum.repos.d/CentOS-Base.repo
更改内容如下

# CentOS-Base.repo
#
# This file uses a new mirrorlist system developed by Lance Davis for CentOS.
# The mirror system uses the connecting IP address of the client and the

# update status of each mirror to pick mirrors that are updated to and
# geographically close to the client. You should use this for CentOS updates
# unless you are manually picking other mirrors.
#
# If the mirrorlist= does not work for you, as a fall back you can try the
# remarked out baseurl= line instead.
#
#

[base]
name=CentOS-$releasever - Base
#mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=os

gpgcheck=1
enabled=0
gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-5

二、update yum

yum -y update

三、利用CentOS Linux系统自带的yum命令安装、升级所需的程序库

LANG=C
yum -y install gcc gcc-c++ autoconf libjpeg libjpeg-devel libpng libpng-devel freetype freetype-devel libxml2 libxml2-devel zlib zlib-devel glibc glibc-devel glib2 glib2-devel bzip2 bzip2-devel ncurses ncurses-devel curl curl-devel e2fsprogs e2fsprogs-devel krb5 krb5-devel libidn libidn-devel openssl openssl-devel openldap openldap-devel nss_ldap openldap-clients openldap-servers

四、安装php和mysql

yum -y install php mysql mysql-server mysql-devel php-mysql php-cgi php-mbstring php-gd php-fastcgi

五、安装nginx
由于centos没有默认的nginx软件包,需要启用REHL的附件包

rpm -Uvh http://download.Fedora.RedHat.com/pub/epel/5/i386/epel-release-5-4.noarch.rpm
yum -y install nginx

设置开机启动

chkconfig nginx on

六、安装spawn-fcgi来运行php-cgi

yum install spawn-fcgi

七、下载spawn-fcgi 的启动脚本

wget http://bash.cyberciti.biz/dl/419.sh.zip
unzip 419.sh.zip
mv 419.sh /etc/init.d/php_cgi
chmod +x /etc/init.d/php_cgi

启动php_cgi

/etc/init.d/php_cgi start

查看进程

netstat -tulpn | grep :9000

若出现如下代表一切正常

tcp 0 0 127.0.0.1:9000 0.0.0.0:* LISTEN 4352/php-cgi

八、配置nginx(详细配置见nginx.conf详细说明)

location ~ \.php$ {
root html;
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME /usr/share/nginx/html$fastcgi_script_name;
include fastcgi_params;
}

九、查看phpinfo
编写脚本

phpinfo();

十、安装phpmyadmin
修改/var/lib/php/session的权限和nginx和php_cgi一致

chown -R www.www /var/lib/php/session
