澹台星剑
一、检查当前系统是否已经安装PHP
# rpm -qa php1
二、查看yum是否有可安装的PHP软件
# yum list | grep php1
[root@localhost ~]# yum list | grep phpgraphviz-php.x86_64 2.30.1-19.el7 base php.x86_64 5.4.16-43.el7_4 updates php-bcmath.x86_64 5.4.16-43.el7_4 updates php-cli.x86_64 5.4.16-43.el7_4 updates php-common.x86_64 5.4.16-43.el7_4 updates php-dba.x86_64 5.4.16-43.el7_4 updates php-devel.x86_64 5.4.16-43.el7_4 updates php-embedded.x86_64 5.4.16-43.el7_4 updates php-enchant.x86_64 5.4.16-43.el7_4 updates php-fpm.x86_64 5.4.16-43.el7_4 updates php-gd.x86_64 5.4.16-43.el7_4 updates php-intl.x86_64 5.4.16-43.el7_4 updates php-ldap.x86_64 5.4.16-43.el7_4 updates php-mbstring.x86_64 5.4.16-43.el7_4 updates php-mysql.x86_64 5.4.16-43.el7_4 updates php-mysqlnd.x86_64 5.4.16-43.el7_4 updates php-odbc.x86_64 5.4.16-43.el7_4 updates php-pdo.x86_64 5.4.16-43.el7_4 updates php-pear.noarch 1:1.9.4-21.el7 base php-pecl-memcache.x86_64 3.0.8-4.el7 base php-pgsql.x86_64 5.4.16-43.el7_4 updates php-process.x86_64 5.4.16-43.el7_4 updates php-pspell.x86_64 5.4.16-43.el7_4 updates php-recode.x86_64 5.4.16-43.el7_4 updates php-snmp.x86_64 5.4.16-43.el7_4 updates php-soap.x86_64 5.4.16-43.el7_4 updates php-xml.x86_64 5.4.16-43.el7_4 updates php-xmlrpc.x86_64 5.4.16-43.el7_4 updates rrdtool-php.x86_64 1.4.8-9.el7 base uuid-php.x86_64 1.6.2-26.el7 base12345678910111213141516171819202122232425262728293031
三、安装PHP
# yum install php1
四、查看版本及支持的扩展
# php -v1

五、
当前系统已安装的mysql版本是：
# rpm -qi mysql-community-server1

安装php-mysqlnd
# yum install php-mysqlnd1
[root@localhost test]# ll /etc/php.d/总用量 48 -rw-r--r--. 1 root root 49 11月 16 00:36 curl.ini -rw-r--r--. 1 root root 57 11月 16 00:36 fileinfo.ini -rw-r--r--. 1 root root 49 11月 16 00:36 json.ini -rw-r--r--. 1 root root 55 11月 16 00:36 mysqlnd.ini -rw-r--r--. 1 root root 69 11月 16 00:36 mysqlnd_mysqli.ini -rw-r--r--. 1 root root 67 11月 16 00:36 mysqlnd_mysql.ini -rw-r--r--. 1 root root 47 11月 16 00:36 pdo.ini -rw-r--r--. 1 root root 63 11月 16 00:36 pdo_mysqlnd.ini -rw-r--r--. 1 root root 61 11月 16 00:36 pdo_sqlite.ini -rw-r--r--. 1 root root 49 11月 16 00:36 phar.ini -rw-r--r--. 1 root root 55 11月 16 00:36 sqlite3.ini -rw-r--r--. 1 root root 47 11月 16 00:36 zip.ini[root@localhost test]# ll /usr/lib64/php/modules/总用量 3772 -rwxr-xr-x. 1 root root 74688 11月 16 00:36 curl.so -rwxr-xr-x. 1 root root 2713376 11月 16 00:36 fileinfo.so -rwxr-xr-x. 1 root root 44688 11月 16 00:36 json.so -rwxr-xr-x. 1 root root 133136 11月 16 00:36 mysqlnd_mysqli.so -rwxr-xr-x. 1 root root 53584 11月 16 00:36 mysqlnd_mysql.so -rwxr-xr-x. 1 root root 256584 11月 16 00:36 mysqlnd.so -rwxr-xr-x. 1 root root 28784 11月 16 00:36 pdo_mysqlnd.so -rwxr-xr-x. 1 root root 116344 11月 16 00:36 pdo.so -rwxr-xr-x. 1 root root 29176 11月 16 00:36 pdo_sqlite.so -rwxr-xr-x. 1 root root 271992 11月 16 00:36 phar.so -rwxr-xr-x. 1 root root 51360 11月 16 00:36 sqlite3.so -rwxr-xr-x. 1 root root 58392 11月 16 00:36 zip.so12345678910111213141516171819202122232425262728
