A. linux centos 7 下用yum 安装iso镜像里自带的php5.4.16版本的但是没有php-fqm文件不知道怎么重启php服务
systemctl restart php-fpm.service #这条命令是重启php服务
下面是一个比较靠谱的php安装步骤：
先删除已有的php版本 ，执行下面的命令删除php
yum remove php-common
然后像安装那样问你是否继续的，输入yes即可
添加 yum 源
CentOS 6.x 的源
# rpm -Uvh http://download.Fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm
# rpm -Uvh http://rpms.famillecollet.com/enterprise/remi-release-6.rpm
安装 PHP
# yum install --enablerepo=remi,remi-php56 php php-opcache php-pecl-apcu php-devel php-mbstring php-mcrypt php-mysqlnd php-phpunit-PHPUnit php-pecl-xdebug php-pecl-xhprof php-pdo php-pear php-fpm php-cli php-xml php-bcmath php-process php-gd php-common
注：安装5.6版本为remi-php56,安装5.5版本为remi-php55
B. 阿里云上的centos 7.2怎么yum安装php 5.6
因之前通过网易的 centos 镜像，将阿里云的 centos 升级到最新版了，乘自己的项目尚未开始正式开发，遂将所有的相应环境都升级到最高。
查看 centos 版本：
[root@iZ23d ~]# cat /etc/centos-release
CentOS Linux release 7.2.1511 (Core)
1、删除之前的 php 版本：
[root@iZ23d ~]# yum remove php* php-common
Loaded plugins: langpacks
Repository base is listed more than once in the configuration
Repository updates is listed more than once in the configuration
Repository extras is listed more than once in the configuration
Repository centosplus is listed more than once in the configuration
No Match for argument: php-5.4.16

No Match for argument: php-7.0.1RC1
No Match for argument: php-7.0.1RC1.tar.gz
No Match for argument: phpMyAdmin-4.4.0.tar.gz
No Match for argument: php-common
No Packages marked for removal
2、rpm 安装 Php7 相应的 yum源：
[root@iZ23d ~]# rpm -Uvh https://mirror.webtatic.com/yum/el7/webtatic-release.rpm
Retrieving https://mirror.webtatic.com/yum/el7/webtatic-release.rpm

Preparing... ################################# [100%]
package webtatic-release-7-3.noarch is already installed
3、 直接yum安装php7：
[root@iZ23d ~]# yum install php70w
Loaded plugins: langpacks
Repository base is listed more than once in the configuration
Repository updates is listed more than once in the configuration
Repository extras is listed more than once in the configuration
Repository centosplus is listed more than once in the configuration

4、检查 php 版本：
[root@iZ23d ~]# php -v

[root@iZ23d2e6hoqZ ~]#
以上显示安装成功！
5、重启 Apache，查看 phpinfo :
[root@iZ23d ~]# systemctl restart httpd.service
检查phpinfo:

C. make: *** [sapi/cli/php] 错误 1 centos源码安装php5.4 make的时候出现以上错误，请问如何解决，谢谢
yum install libxml2
后重新编译PHP看看
D. LINUX安装PHP的RPM包遇到的提示： [root@localhost ~]# rpm -ivh /mnt/cdrom/CentOS/php-cli-5.1.6-20.el5
遇到什么提示？
E. 如何在CentOS系统中把PHP 5.3.x更新到PHP 5.4.x
1.首页安装Webtatic EL6 YUM源
rpm -Uvh
2.停止web服务器
service nginx stop
或者
service httpd stop
3.删除当前的 php 安装 php5.4
yum remove php*
yum install php54w
4.重启web服务器
service php-fpm restart
service nginx start
或者
service httpd restart
5.查看php版本
php -v

F. centos怎么彻底卸载php
想把PHP卸载干净，直接用yum的remove命令是不行的，需要查看有多少rpm包，然后按照依赖顺序逐一卸载。
1.首先查看机器上安装的所有php相关的rpm包
[root@localhost nginx]# rpm -qa | grep php
php-cli-5.3.3-22.el6.x86_64
php-pdo-5.3.3-22.el6.x86_64
php-gd-5.3.3-22.el6.x86_64
php-fpm-5.3.3-22.el6.x86_64
php-common-5.3.3-22.el6.x86_64
php-5.3.3-22.el6.x86_64
php-xml-5.3.3-22.el6.x86_64
php-pear-1.9.4-4.el6.noarch
2.按依赖顺序进行删除
rpm -e php-fpm-5.3.3-22.el6.x86_64
rpm-e php-pdo-5.3.3-22.el6.x86_64
rpm -e php-pear-1.9.4-4.el6.noarch
rpm-e php-cli-5.3.3-22.el6.x86_64
rpm -e php-5.3.3-22.el6.x86_64
rpm-e php-xml-5.3.3-22.el6.x86_64
rpm -e php-gd-5.3.3-22.el6.x86_64
rpm-e php-common-5.3.3-22.el6.x86_64
G. CentOS怎样强制卸载PHP以及自定义安装PHP
查看php版本命令：
#php -v
这个命令是删除不干净的
#yum remove php
因为使用这个命令以后再用
#php -v
还是会看到有版本信息的。。。。。
必须强制删除
#rpm -qa|grep php
提示如下
#php-pdo-5.1.6-27.el5_5.3
#php-mysql-5.1.6-27.el5_5.3
#php-xml-5.1.6-27.el5_5.3
#php-cli-5.1.6-27.el5_5.3
#php-common-5.1.6-27.el5_5.3
#php-gd-5.1.6-27.el5_5.3
注意卸载要先卸载没有依赖的
pdo是mysql的依赖项；common是gd的依赖项；
例如：# rpm -e php-pdo-5.1.6-27.el5_5.3
error: Failed dependencies:
php-pdo is needed by (installed) php-mysql-5.1.6-27.el5_5.3.i386
所以正确的卸载顺序是：
# rpm -e php-mysql-5.1.6-27.el5_5.3
# rpm -e php-pdo-5.1.6-27.el5_5.3
# rpm -e php-xml-5.1.6-27.el5_5.3
# rpm -e php-cli-5.1.6-27.el5_5.3
# rpm -e php-gd-5.1.6-27.el5_5.3
# rpm -e php-common-5.1.6-27.el5_5.3
再用# php -v
查看版本信息已经没有提示
安装最新的PHP
wget
tar xzvf php-5.3.6.tar.gz
cd php-5.3.6
./configure --prefix=/usr/local/php
H. 如何在CentOS 6上通过YUM安装Nginx和PHP
在CentOS 6上通过YUM安装Nginx和PHP-FPM：
第一步，在/etc/yum.repos.d/目录下创建一个源配置文件nginx.repo：
cd /etc/yum.repos.d/
vim nginx.repo
填写如下内容：
[nginx]
name=nginx repo
baseurl=nginx.org/packages/centos/$releasever/$basearch/
gpgcheck=0
enabled=1
保存，则会产生一个/etc/yum.repos.d/nginx.repo文件。
下面直接执行如下指令即可自动安装好Nginx：
yum install nginx -y
安装完成，下面直接就可以启动Nginx了：
/etc/init.d/nginx start
现在Nginx已经启动了，直接访问服务器就能看到Nginx欢迎页面了的。
I. 安装centos时自动安装的php怎么卸载
