Centos7下Vestacp面板升级php版本到7.1

PHP 7 使用新版的ZendEngine引擎，带来了许多新的特性。

PHP 7 相对于 php 5.x 版本在性能方面得到了极大的提高。

然而Vestacp面板一直是用php5.6，面对php7的性能提升，博主本人还是很想试试使用php7.1。

一、准备工作

1.一台安装了Vestacp的机器。

2.备份数据(防止出错后数据丢失)

二、升级php版本

Centos

Centos版本7.4

1.安装epel和remi源（这个不是必须的，先确定一下yum源里有这两个源）

ll /etc/yum.repos.d

如果没有，需要以下命令来安装

 # 如果是CentOS 6的话,就把地址里的7改成6
 wget https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm
 wget http://rpms.remirepo.net/enterprise/remi-release-7.rpm
 rpm -Uvh remi-release-7.rpm epel-release-latest-7.noarch.rpm
 # 升级remi源
 yum -y --enablerepo=remi update remi-release

2.停止httpd并卸载旧版本php

#如果仅安装了nginx，那么要停掉php-fpm
service php-fpm stop
#如果安装了apache，那要停止httpd
service httpd stop
#卸载旧版本php
yum -y remove php

3.安装php7.1

yum -y --enablerepo=remi-php71 install php php-pear php-bcmath php-mysqlnd php-gd php-common php-fpm php-intl php-cli php-xml php-pecl-apcu php-pdo php-gmp php-process php-pecl-imagick php-devel php-mbstring

这个时候可能会遇到一个错误，如下图所示：

 You could try using --skip-broken to work around the problem
 You could try running: rpm -Va --nofiles --nodigest

解决办法是：remove掉错误的包，我remove掉第一个包后就正常了！

yum remove php-pecl-igbinary-2.0.5~RC1-1.el7.remi.5.6.x86_64

4.安装memcache客户端以及opcache

yum -y --enablerepo=remi-php71 install php-opcache php-memcache

5.重启php-fpm或是httpd

#启动php-fpm
service php-fpm start
#启动httpd
service httpd start

最后php-v查看一下php版本
