1、升级前检测当前PHP版本 # php -v 2、检查当前php的安装包 # yum list installed | grep php 3、检查当前PHP的安装包 由于默认的YUM源无法升级PHP，所以需要添加第三方的YUM源，此处用到webtatic。 因为是CentOS 6.5，所以用以下URL # rpm -Uvh http://mirror.webtatic.com/yum/el6/latest.rpm 如果是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 4、查看YUM源上能用PHP安装包 ＃ yum list php* 5、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 (责任编辑：IT) |
