[root@VM_0_10_centos ~]# yum list installed | grep php

2. 完全移除当前PHP安装包以免起冲突

1
[root@VM_0_10_centos ~]# yum remove php*

3. 查看当前yum源都提供了哪些可安装的PHP版本

1
[root@VM_0_10_centos ~]# yum list php*

注意：默认的yum源无法升级PHP，需要添加第三方yum源，我们选择webtatic库

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

4、安装PHP及相关插件，这里以PHP7.1.x为例

1
yum install php71w php71w-cli php71w-common php71w-devel php71w-embedded php71w-fpm php71w-gd php71w-mbstring php71w-mysqlnd php71w-opcache php71w-pdo php71w-xml php71w-ldap php71w-mcrypt php71w-bcmath

5、如果安装了PHP的扩展库，可以通过pecl命令安装

5.1 安装pecl

# 如果php < 7
$ yum install php-pear

# 如果php >= 7
$ wget http://pear.php.net/go-pear.phar
$ php go-pear.phar
# 否则会报PHP syntax error, unexpected 'new' (T_NEW) in /usr/share/pear/PEAR/Frontend.php on line 91

5.2 安装mongo扩展

1
$ pecl install mongodb

5.3 安装mosquitto扩展

1
$ pecl install mosquitto -c channel://pecl.php.net/mosquitto-0.4.0

5.4 查看使用pecl安装的扩展有哪些

$ pecl list
Installed packages, channel pecl.php.net:
=========================================
Package   Version State
Mosquitto 0.4.0   beta
mongodb   1.5.3   stable

6、如果服务器运行了PHP的web程序，需要重启php-fpm

1
[root@VM_0_10_centos ~]# systemctl restart php-fpm

7. 查看PHP版本
