CentOS7 は Apache+PHP+MariaDB をインストールします

まず、Apacheサーバーをインストールします

<code>yum <span>install</span> httpd</code>

2番目、PHPと一般的なソフトウェアパッケージをインストールします

<code>yum install php httpd<span>-manual</span> mod_ssl mod_perl mod_auth_mysql
yum install php<span>-gd</span> php<span>-xml</span> php<span>-mbstring</span> php<span>-ldap</span> php<span>-pear</span> php<span>-xmlrpc</span>
yum install mysql<span>-connector</span><span>-odbc</span> mysql<span>-devel</span> libdbi<span>-dbd</span><span>-mysql</span></code>

3番目、MariaDBをインストールします

<code>yum <span>install</span> mariadb* </code>

4番目、サービスを開始します

<code>systemctl <span><span>start</span> httpd.service
systemctl <span>start</span> mariadb.service</span></code>

5番目、4番目のステップが成功した場合は、セットアップします2 つのサービスを自動的に開始します

<code>systemctl enable httpd<span>.service</span>
systemctl enable mariadb<span>.service</span></code>

6 番目、データベースサーバーをセットアップします

<code>[root@rachel ~]<span>#  mysql -u root #无密码登录数据库</span>
