php7的内部结构与5截然不同,性能上的大突破,能比前一版PHP 5快上一倍,所以今天在centos7.2上部署Php7,体验一下它的性能。
一、查看centos版本
[root@localhost ~]# cat /etc/redhat-release CentOS Linux release 7.2.1511 (Core)
二、删除之前的 php 版本
如果是第一次安装省略...
[root@localhost ~]# yum remove php* php-common
三、rpm 安装 Php7 相应的 yum源
[root@localhost ~]# rpm -Uvh https://mirror.webtatic.com/yum/el7/webtatic-release.rpm
注意:如果报错,以下是报错信息:
Retrieving https://mirror.webtatic.com/yum/el7/webtatic-release.rpm warning: /var/tmp/rpm-tmp.o0rIru: Header V4 RSA/SHA1 Signature, key ID 62e74ca5: NOKEY error: Failed dependencies: epel-release >= 7 is needed by webtatic-release-7-3.noarch
在安装包后面加两个参数,如
[root@localhost ~]# rpm -Uvh https://mirror.webtatic.com/yum/el7/webtatic-release.rpm --nodeps --force
加上那两个参数的意义就在于,
安装时不再分析包之间的依赖关系而直接安装,
也就不会再提示error: Failed dependencies:这样的错误了
正确返回:
Retrieving https://mirror.webtatic.com/yum/el7/webtatic-release.rpm warning: /var/tmp/rpm-tmp.0nuQEZ: Header V4 RSA/SHA1 Signature, key ID 62e74ca5: NOKEY Preparing... ################################# [100%] Updating / installing... 1:webtatic-release-7-3 ################################# [100%]
四、直接yum安装php7
现在可以直接yum安装php7
[root@localhost ~]# yum install php70w
一路“y”
最后成功返回:
.... Installed: php70w.x86_64 0:7.0.10-1.w7 Dependency Installed: apr.x86_64 0:1.4.8-3.el7 apr-util.x86_64 0:1.5.2-6.el7 httpd.x86_64 0:2.4.6-40.el7.centos.4 httpd-tools.x86_64 0:2.4.6-40.el7.centos.4 mailcap.noarch 0:2.1.41-2.el7 php70w-cli.x86_64 0:7.0.10-1.w7 php70w-common.x86_64 0:7.0.10-1.w7 Complete!
五、检查 php 版本
[root@localhost ~]# php -v
返回:
PHP 7.0.10 (cli) (built: Aug 20 2016 07:47:25) ( NTS ) Copyright (c) 1997-2016 The PHP Group Zend Engine v3.0.0, Copyright (c) 1998-2016 Zend Technologies
5、重启 Apache或Nginx,查看 phpinfo :
Apache:
[root@localhost ~]# systemctl restart httpd.service
ngingx:
[root@localhost ~]# systemctl restart nginx.service
