linux 下php多版本安装
php-multi-version
ubuntu apt-get 安装php5.6
- 添加软件源
sudo add-apt-repository ppa:ondrej/php
sudo apt-get update
sudo apt-get install php5.6
sudo apt-get install php5
sudo apt-get install php7
/usr/local/bin 与/usr/bin
echo $PATH
/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games
如果安装了多个版本php，如apt-get 安装了php5 会放在/usr/bin/php ，如果再源码安装默认时/usr/local/bin/php
如果命令行下执行php -v执行的是/usr/local/bin/php。如果想让默认的执行/usr/bin/php，可以建立软链接
sudo mv /usr/local/bin/php /usr/local/bin/php5.5
sudo ln -s /usr/bin/php /usr/local/bin/php
相应的phpize php-config等也需要修改
源码安装
- 创建用户
useradd www-data -s /sbin/nologin -M
- 配制
