刚开始用LINUX没什么经验，CentOS 6.5自带PHP5，当时不会删就留着了，然后安装了PHP7. 现在查看php -v结果显示的是PHP 5.6. 怎么让系统默认使用PHP7呢？

刚刚把PHP全删了“yum remove php*”，然后用YUM安装了PHP7，现在php -v显示是PHP 7了。

但是运行php-fpm的时候提示找不到文件。我又用yum --enablerepo=remi install php php-fpm 安装了一下php-fpm，执行后提示：

yum install php php-fpm php-mysql Failed to set locale, defaulting to C Loaded plugins: refresh-packagekit, security Setting up Install Process Resolving Dependencies --> Running transaction check ---> Package php.x86_64 0:5.3.3-48.el6_8 will be installed --> Processing Dependency: php-common(x86-64) = 5.3.3-48.el6_8 for package: php-5.3.3-48.el6_8.x86_64 --> Processing Dependency: php-cli(x86-64) = 5.3.3-48.el6_8 for package: php-5.3.3-48.el6_8.x86_64 ---> Package php-fpm.x86_64 0:5.3.3-48.el6_8 will be installed ---> Package php-mysql.x86_64 0:5.3.3-48.el6_8 will be installed --> Running transaction check ---> Package php-cli.x86_64 0:5.3.3-48.el6_8 will be installed ---> Package php-common.x86_64 0:5.3.3-48.el6_8 will be installed --> Processing Conflict: php70w-common-7.0.15-1.w6.x86_64 conflicts php-common < 7.0 --> Finished Dependency Resolution Error: php70w-common conflicts with php-common-5.3.3-48.el6_8.x86_64 You could try using --skip-broken to work around the problem You could try running: rpm -Va --nofiles --nodigest

运行php-fpm依然提示“-bash: /usr/sbin/php-fpm: No such file or directory”

再试这个安装：
yum install php70-php-fpm.x86_64

运行 php-fpm
显示
-bash: php-fpm: command not found

该怎么解决呢？

安装完php-fpm之后，最后提示

--> Finished Dependency Resolution
Error: php70w-common conflicts with php-common-5.3.3-48.el6_8.x86_64
You could try using --skip-broken to work around the problem
You could try running: rpm -Va --nofiles --nodigest

感觉是PHP5没删干净，跟PHP7冲突。 怎么删掉 php-common-5.3.3-48.el6_8.x86_64 ？
