centos如何查看php版本

A. 阿里雲默認centos7上怎麼安裝php

首先更新系統軟體</str>
$ yum update
安裝nginx</str></str>
1.安裝nginx源
$ yum localinstall http://nginx.org/packages/centos/7/noarch/RPMS/nginx-release-centos-7-0.el7.ngx.noarch.rpm2.安裝nginx
$ yum install nginx
3.啟動nginx
$ service nginx start
Redirecting to /bin/systemctl start nginx.service4.訪問http://你的ip/
如果成功安裝會出來nginx默認的歡迎界面
安裝MySQL5.7.*
</str>
1.安裝mysql源</str>
$ yum localinstall http://dev.mysql.com/get/mysql57-community-release-el7-7.noarch.rpm2.安裝mysql
$ yum install mysql-community-server
確認一下mysql的版本，有時可能會提示mysql5.63.安裝mysql的開發包，以後會有用
$ yum install mysql-community-devel
4.啟動mysql
$ service mysqld start
Redirecting to /bin/systemctl start mysqld.service5.查看mysql啟動狀態
$ service mysqld status
出現pid
證明啟動成功
6.獲取mysql默認生成的密碼
$ grep 'temporary password' /var/log/mysqld.log2015-12-05T05:41:09.104758Z 1 [Note] A temporary password is generated for root@localhost: %G1Rgns!dD!v</str>
加粗的就是生成的密碼
7.換成自己的密碼
$ mysql -uroot -p
Enter password:輸入上面的密碼
成功輸入後進入一下步，這里你估計會輸入 好幾次才進去8. 更換密碼
mysql> ALTER USER 'root'@'localhost' IDENTIFIED BY 'MyNewPass4!';這個密碼一定要足夠復雜，不然會不讓你改，提示密碼不合法;9.退出mysql;
mysql> quit;
10.用新密碼再登錄，試一下新密碼
$ mysql -uroot -p
Enter password:輸入你的新密碼
11.確認密碼正確後，退出mysql;
mysql> quit;
編譯安裝php7.0.0
</str>
</str>
1.下載php7源碼包</str>
$ cd /root & wget -O php7.tar.gz http://cn2.php.net/get/php-7.0.1.tar.gz/from/this/mirror2.解壓源碼包</str>
$ tar -xvf php7.tar.gz
3.</str>
$ cd php-7.0.1
4.安裝php依賴包</str>
</str>
$ yum install libxml2 libxml2-devel openssl openssl-devel bzip2 bzip2-devel libcurl libcurl-devel libjpeg libjpeg-devel libpng libpng-devel freetype freetype-devel gmp gmp-devel libmcrypt libmcrypt-devel readline readline-devel libxslt libxslt-devel5.編譯配置，這一步我們會遇到很多configure error，我們一一解決，基本都是相關軟體開發包沒有安裝導致</str>

解決：
$ yum install libxml2 libxml2-devel
2.configure: error: Cannot find OpenSSL's <evp.h>
解決：
$ yum install openssl openssl-devel
3.configure: error: Please reinstall the BZip2 distribution解決：

6.編譯與安裝
$ make && make install
這里要make好久，要耐心一下
7.添加 PHP 命令到環境變數
$ vim /etc/profile
在末尾加入
PATH=$PATH:/usr/local/php/bin
export PATH
要使改動立即生效執行
$ ./etc/profile
或
$ source /etc/profile
查看環境變數
$ echo $PATH
查看php版本
$ php -v
8.配置php-fpm
$ cp php.ini-proction /etc/php.ini
$ cp /usr/local/php/etc/php-fpm.conf.default /usr/local/php/etc/php-fpm.conf$ cp /usr/local/php/etc/php-fpm.d/www.conf.default /usr/local/php/etc/php-fpm.d/www.conf$ cp sapi/fpm/init.d.php-fpm /etc/init.d/php-fpm$ chmod +x /etc/init.d/php-fpm
9.啟動php-fpm
$ /etc/init.d/php-fpm start
配置nginx虛擬機,綁定域名</str>
1.
</str>
$ vim /etc/nginx/conf.d/php7.thinkcmf.com.conf這里可以把php7.thinkcmf.com.conf改成自己的域名把下面的內容復制到php7.thinkcmf.com.conf里server{
listen 80;
server_name php7.thinkcmf.com;
root /var/www/html/php7.thinkcmf.com; # 該項要修改為你准備存放相關網頁的路徑location / {
index index.php index.html index.htm;
#如果請求既不是一個文件，也不是一個目錄，則執行一下重寫規則if (!-e $request_filename)
{
#地址作為將參數rewrite到index.php上。
rewrite ^/(.*)$ /index.php/$1;
#若是子目錄則使用下面這句，將subdir改成目錄名稱即可。
#rewrite ^/subdir/(.*)$ /subdir/index.php/$1;}
}
#proxy the php scripts to php-fpm
location ~ \.php {
include fastcgi_params;
##pathinfo支持start
#定義變數 $path_info ，用於存放pathinfo信息set $path_info "";
#定義變數 $real_script_name，用於存放真實地址set $real_script_name $fastcgi_script_name;#如果地址與引號內的正則表達式匹配
if ($fastcgi_script_name ~ "^(.+?\.php)(/.+)$") {#將文件地址賦值給變數 $real_script_name
set $real_script_name $1;
#將文件地址後的參數賦值給變數 $path_info
set $path_info $2;
}
#配置fastcgi的一些參數
fastcgi_param SCRIPT_FILENAME $document_root$real_script_name;fastcgi_param SCRIPT_NAME $real_script_name;fastcgi_param PATH_INFO $path_info;
###pathinfo支持end
fastcgi_intercept_errors on;
fastcgi_pass 127.0.0.1:9000;
}
}
2.重啟nginx
$ service nginx reload
3.
$ vim /var/www/html/php7.thinkcmf.com/index.php</str>
把下面的代碼復制到這個文件 里
<?php
phpinfo();
4.查看訪問http://php7.thinkcmf.com

B. centos 安裝php怎麼選擇版本

一般默認的版本比較低,你可以先添加源,然後yum list php* ,安裝你想要安裝的版本,如yum install php56w

C. 阿里雲上的centos 7.2怎麼yum安裝php 5.6

因之前通過網易的 centos 鏡像，將阿里雲的 centos 升級到最新版了，乘自己的項目尚未開始正式開發，遂將所有的相應環境都升級到最高。
查看 centos 版本：
[root@iZ23d ~]# cat /etc/centos-release
CentOS linux release 7.2.1511 (Core)
1、刪除之前的 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-5.4.16.tar.gz
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 安裝 Php7 相應的 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
warning: /var/tmp/rpm-tmp.LhJKKR: Header V4 RSA/SHA1 Signature, key ID 62e74ca5: NOKEY
Preparing... ################################# [100%]
package webtatic-release-7-3.noarch is already installed
3、 直接yum安裝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

Complete!
4、檢查 php 版本：
[root@iZ23d ~]# php -v
PHP 7.0.0 (cli) (built: Dec 2 2015 20:42:32) ( NTS )
Copyright (c) 1997-2015 The PHP Group
Zend Engine v3.0.0, Copyright (c) 1998-2015 Zend Technologies
[root@iZ23d2e6hoqZ ~]#
以上顯示安裝成功！
5、重啟 Apache，查看 phpinfo :
[root@iZ23d ~]# systemctl restart httpd.service
檢查phpinfo:

以上顯示 php7 安裝成功！

D. linux系統查看php版本的口令是什麼

linux系統查看php版本的命令是：

1. 登錄linux伺服器執行以下命令：

php-v

輸出：

PHP5.4.45(cli)(built:Oct11201623:35:56)
Copyright(c)1997-2014ThePHPGroup
ZendEnginev2.4.0,Copyright(c)1998-2014ZendTechnologies
withtheionCubePHPLoader(enabled)+.com(unconfigured)v6.0.6,Copyright(c)2002-2016,byionCubeLtd.
withZendGuardLoaderv3.3,Copyright(c)1998-2013,byZendTechnologies

說明：php -v會輸出php的版本。

注意事項：centos下可以執行php -v命令。

E. centos7系統Apache+php+mysql環境，怎麼升級PHP版本

yum install php php-devel
重啟apache使php生效
systemctl restart httpd.service
此時可以在目錄：/var/www/html/下建立一個PHP文件
代碼：
<?php phpinfo(); ?>

然後訪問這個文件，就能看到PHP的一些信息，php.ini配置文件的路徑可以在這個頁面上看到

安裝php的擴展
yum install php-mysql php-gd php-imap php-ldap php-odbc php-pear php-xml php-xmlrpc
安裝完擴展之後需要再次重啟apache
systemctl restart httpd.service

F. centos 如何檢測php安裝

需要准備的材料分別是：電腦、centos主機，linux連接工具。

1、首先連接上centos主機，進入等待輸入指令的linux命令行狀態。
