现在大家都在用一键包了，还有可视化的面板，如宝塔等，但是也有一些朋友在使用最原始的手工安装和编译，这样的好处是节省一些内存及硬盘，一些你平时根本用不的程序不会被安装，下面就给大家分享一下如果安装LAMP（Linux+apache+mysql+php）。

安装Apache

执行以下命令

yum -y install httpd httpd-manual mod_ssl mod_perl mod_auth_mysql

1	yum -y install httpd httpd-manual mod_ssl mod_perl mod_auth_mysql

返回类似如下图结果则表示安装成功。

执行如下命令，启动Apache服务。

systemctl <span class="hljs-operator"><span class="hljs-keyword">start</span> httpd.service</span>

1	systemctl <span class="hljs-operator"><span class="hljs-keyword">start</span> httpd.service</span>

测试Apache服务是否安装并启动成功。

Apache默认监听80端口，所以只需在浏览器访问ECS分配的IP地址http://<ECS公网地址>，如下图：

安装Mysql

执行如下命令，下载并安装MySQL官方的Yum Repository。

wget http:<span class="hljs-comment">//dev.mysql.com/get/mysql57-community-release-el7-10.noarch.rpm</span>

1	wget http:<span class="hljs-comment">//dev.mysql.com/get/mysql57-community-release-el7-10.noarch.rpm</span>

yum -y <span class="hljs-operator"><span class="hljs-keyword">install</span> mysql57-community-<span class="hljs-keyword">release</span>-el7-<span class="hljs-number">10.</span>noarch.rpm</span>

1	yum -y <span class="hljs-operator"><span class="hljs-keyword">install</span> mysql57-community-<span class="hljs-keyword">release</span>-el7-<span class="hljs-number">10.</span>noarch.rpm</span>

yum -y <span class="hljs-operator"><span class="hljs-keyword">install</span> mysql-community-<span class="hljs-keyword">server</span></span>

1	yum -y <span class="hljs-operator"><span class="hljs-keyword">install</span> mysql-community-<span class="hljs-keyword">server</span></span>

执行如下命令，启动 MySQL 数据库。

systemctl <span class="hljs-operator"><span class="hljs-keyword">start</span> mysqld.service</span>

1	systemctl <span class="hljs-operator"><span class="hljs-keyword">start</span> mysqld.service</span>

执行如下命令，查看MySQL运行状态。

<span class="hljs-title">systemctl</span> status mysqld.service

1	<span class="hljs-title">systemctl</span> status mysqld.service

执行如下命令，查看MySQL初始密码。

<span class="hljs-keyword">grep</span> <span class="hljs-string">"password"</span> /var/<span class="hljs-keyword">log</span>/mysqld.<span class="hljs-keyword">log</span>

1	<span class="hljs-keyword">grep</span> <span class="hljs-string">"password"</span> /var/<span class="hljs-keyword">log</span>/mysqld.<span class="hljs-keyword">log</span>

执行如下命令，登录数据库。

<span class="hljs-title">mysql</span> -uroot -p

1	<span class="hljs-title">mysql</span> -uroot -p

执行如下命令，修改MySQL默认密码。

说明?新密码设置的时候如果设置的过于简单会报错，必须同时包含大小写英文字母、数字和特殊符号中的三类字符。

<span class="hljs-operator"><span class="hljs-keyword">ALTER</span> <span class="hljs-keyword">USER</span> <span class="hljs-string">'root'</span>@<span class="hljs-string">'localhost'</span> <span class="hljs-keyword">IDENTIFIED</span> <span class="hljs-keyword">BY</span> <span class="hljs-string">'NewPassWord1.'</span>;</span>

1

<span class="hljs-operator"><span class="hljs-keyword">ALTER</span> <span class="hljs-keyword">USER</span> <span class="hljs-string">'root'</span>@<span class="hljs-string">'localhost'</span> <span class="hljs-keyword">IDENTIFIED</span> <span class="hljs-keyword">BY</span> <span class="hljs-string">'NewPassWord1.'</span>;</span>

?执行如下命令，创建wordpress库。

<span class="hljs-operator"><span class="hljs-keyword">create</span> <span class="hljs-keyword">database</span> wordpress;</span>

1	<span class="hljs-operator"><span class="hljs-keyword">create</span> <span class="hljs-keyword">database</span> wordpress;</span>

?执行如下命令，创建wordpress库。 执行如下命令，查看是否创建成功。

<span class="hljs-operator"><span class="hljs-keyword">show</span> <span class="hljs-keyword">databases</span>;</span>

1	<span class="hljs-operator"><span class="hljs-keyword">show</span> <span class="hljs-keyword">databases</span>;</span>

?输入exit退出数据库。

安装PHP

执行如下命令，安装PHP环境。

yum -y <span class="hljs-operator"><span class="hljs-keyword">install</span> php php-mysql gd php-gd gd-devel php-<span class="hljs-keyword">xml</span> php-common php-mbstring php-ldap php-pear php-xmlrpc php-imap</span>

1	yum -y <span class="hljs-operator"><span class="hljs-keyword">install</span> php php-mysql gd php-gd gd-devel php-<span class="hljs-keyword">xml</span> php-common php-mbstring php-ldap php-pear php-xmlrpc php-imap</span>

?执行如下命令创建PHP测试页面。

echo "<span class="php"><span class="hljs-preprocessor">&lt;?php</span> phpinfo(); <span class="hljs-preprocessor">?&gt;</span></span>" &gt; /var/www/html/phpinfo.php

1	echo "<span class="php"><span class="hljs-preprocessor">&lt;?php</span> phpinfo(); <span class="hljs-preprocessor">?&gt;</span></span>" &gt; /var/www/html/phpinfo.php

执行如下命令，重启Apache服务。

<span class="hljs-title">systemctl</span> restart httpd

1	<span class="hljs-title">systemctl</span> restart httpd

打开浏览器，访问http://<ECS公网地址>/phpinfo.php，显示如下页面表示PHP语言环境安装成功。
