将centos6的php5.3升级为5.6

在阿里云主机上，操作系统是Centos6，php版本是5.3。因为安装Yii2.0的需要，我要升级php为5.4。因为还有5.5和5.6，当然要升到高版本了。我决定升到5.6。

 

首先，按照这里的步骤

只有php-fpm没有正确安装，所以无法启动之。下面试图单独安装。

 

[root@AY14022011465274454aZ ~]# yum install php-fpm

Loaded plugins: fastestmirror

You could try using --skip-broken to work around the problem

You could try running: rpm -Va --nofiles --nodigest

# yum install php56w-fpm

# service php-fpm start

Starting php-fpm: Failed loading /usr/lib64/php/modules/ZendGuardLoader.so: /usr/lib64/php/modules/ZendGuardLoader.so: undefined symbol: zend_get_hash_value

[ OK ]

（这个错误信息是怎么回事？此后一直伴随，好在没有其它影响，先不管它）

后续：

1、执行数据库操作时，找不到PDO模块

试着用下面指令

# yum install -y libxml2-devel openssl-devel libcurl-devel libjpeg-devel libpng-devel libicu-devel openldap-devel freetype freetype-devel # --没用

 

# 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 #--出错

 

# yum install php56w-pdo #--成功

重启php-fpm服务，这次yii出现新的错误

CDbConnection failed to open the DB connection: could not find driver

 

# yum install php56w-mysql

重启服务，这次yii不出错了，但渲染一小块内容，确切地说，只渲染action自己的view的那一块东西，layout/main.php的没过来。

 

# yum install php56w-mbstring

这次渲染正确了。

 

发现在饭店查询时出现错误：

include(DOMDocument.php): failed to open stream: No such file or directory

 

# yum install php56w-dom

成功了。（估计是在解析xml的时候出错了。）

以上是为记录。留作备忘。
