CentOS7 LNMP+phpmyadmin环境搭建 第二篇LNMP环境搭建教程
<p>上一篇博客我们在虚拟机上安装了centos7，接下来，就开始安装lnmp环境吧。</p>
<p>
还是跟之前一样，进入命令行后，先使用su命令切换到root权限。</p>
<p>
首先<strong>配置防火墙</strong></p>
<p>
centos 7.0默认使用的是firewall作为防火墙</p>
<p>
1.关闭firewall：</p>
<div class="jb51code">
<div>
<div class="syntaxhighlighterbash" id="highlighter_212337">
<div class="toolbar">
<span>?</span>
</div>
<table border="0" cellpadding="0" cellspacing="0"><tbody><tr>
<td class="gutter">
<div class="line number1 index0 alt2">
1</div>
<div class="line number2 index1 alt1">
2</div>
</td>
<td class="code">
<div class="container">
<div class="line number1 index0 alt2">
<code class="bash plain">systemctl stop firewalld.service </code><code class="bash comments">#停止firewall </code>
</div>
<div class="line number2 index1 alt1">
<code class="bash plain">systemctl disable firewalld.service </code><code class="bash comments">#禁止firewall开机启动</code>
</div>
</div>
</td>
</tr></tbody></table>
</div>
</div>
</div>
<p>
2.关闭selinux：</p>
<div class="jb51code">
<div>
<div class="syntaxhighlighterbash" id="highlighter_774090">
<div class="toolbar">
<span>?</span>
</div>
<table border="0" cellpadding="0" cellspacing="0"><tbody><tr>
<td class="gutter">
<div class="line number1 index0 alt2">
1</div>
</td>
<td class="code">
<div class="container">
<div class="line number1 index0 alt2">
<code class="bash functions">vi</code> <code class="bash plain">/etc/selinux/config</code>
</div>
</div>
</td>
</tr></tbody></table>
</div>
</div>
</div>
<p>
#selinux=enforcing #注释掉</p>
<p>
selinux=disabled #增加</p>
<p>
:wq! #保存退出</p>
<p>
setenforce 0 #使配置立即生效</p>
<p>

<p>
通过随机密码登陆mysql（随机密码比较难辨认，多几次，我在登陆的时候就因为看错密码试了两次才成功）</p>

<p>
修改mysql登陆密码（注意不要漏掉分号，这是mysql的语句，修改完成后使用exit退出后再次登陆）</p>

<span><strong>注意：</strong></span>mysql5.7默认安装了密码安全检查插件（validate_password），默认密码检查策略要求密码必须包含：大小写字母、数字和特殊符号，并且长度不能少于8位。否则会提示error 1819 (hy000): your password does not satisfy the current policy requirements错误，如下所示：</p>
<p>
alter user ‘root'@'localhost' identified by ‘mynewpass4!';<br>
set password for ‘root'@'localhost'=password(‘mynewpass4!');<br>
通过msyql环境变量可以查看密码策略的相关信息：</p>

<p>
如果上面的方式不能修改可以使用下面安全模式修改root：<br>
关闭服务<br>
systemctl stop mysqld.service<br>
vi /etc/my.cnf<br>
mysqld下面添加skip-grant-tables 保存退出启动服务<br>
systemctl start mysqld.service<br>
mysql -u root 不用密码直接回车<br>
use mysql<br>
update user set authentication_string=password(‘root-123') where user='root'and host='localhost';<br>
flush privileges;<br>
exit;<br>
vi /etc/my.cnf 把 skip-grant-tables 一句删除保存退出重启mysql服务<br>
systemctl restart mysqld.service<br>
再次登录即可<br>
mysql -u root -proot-123</p>
<p>
如果进行操作出现下面的提示:<br>
you must reset your password using alter user statement before executing thisstatement.<br>
就再设置一遍密码<br>
set password = password(‘root-123');</p>
<p>
开放3306端口（允许使用用户名root密码root-123456从任何主机连接到mysql服务器）</p>

<p>
<strong>2.安装php</strong></p>
<p>
yum默认安装的php版本较低，这次，我们准备安装php5.6版本，所以需要先安装epel库，然后安装php。</p>
<div class="jb51code">
<div>
<div class="syntaxhighlighterbash" id="highlighter_930875">
<div class="toolbar">

</div>
</div>
</td>
</tr></tbody></table>
</div>
</div>
</div>
<p>
安装完成后键入php -v会显示出php的版本，代表我们php安装完成了。</p>

<p>
<strong>3.安装nginx</strong></p>
<p>
</p>
<div class="codetitle">
<span><u>复制代码</u></span> 代码如下:</div>
<div class="codebody" id="code80411">
wget http://nginx.org/packages/centos/7/noarch/rpms/nginx-release-centos-7-0.el7.ngx.noarch.rpm<br>
rpm -ivh nginx-release-centos-7-0.el7.ngx.noarch.rpm</div>
<p>
</p>
<p>
然后启动nginx</p>
<div class="jb51code">
<div>
<div class="syntaxhighlighterbash" id="highlighter_380404">
<div class="toolbar">
<span>?</span>
</div>
<table border="0" cellpadding="0" cellspacing="0"><tbody><tr>

<div class="line number2 index1 alt1">

<div class="line number3 index2 alt2">

<div class="line number4 index3 alt1">

</td>
<td class="code">
<div class="container">
<div class="line number1 index0 alt2">

</div>
</div>
</td>
</tr></tbody></table>
</div>
</div>
</div>
<p>
.更改nginx端口号（根据自己需求）</p>
<p>
cd /etc/nginx/conf.d/ <br>
vim default.conf <br>
把listen 80改成listen 81<br>
然后重启nginx<br>
systemctl restart nginx.service #重启nginx</p>
<p>
<img style="max-width:100%!important;height:auto!important;"title="CentOS7 LNMP+phpmyadmin环境搭建 第二篇LNMP环境搭建教程" alt="CentOS7 LNMP+phpmyadmin环境搭建 第二篇LNMP环境搭建教程" src="https://zhuji.jb51.net/uploads/img/202305/095b948c3082bde48edb5b71f7cbecd0.jpg"></p>
<p>
这时我们打开浏览器，访问localhost如果出现welcome to nginx!那么nginx就安装成功了</p>
<p>
<img style="max-width:100%!important;height:auto!important;"title="CentOS7 LNMP+phpmyadmin环境搭建 第二篇LNMP环境搭建教程" alt="CentOS7 LNMP+phpmyadmin环境搭建 第二篇LNMP环境搭建教程" src="https://zhuji.jb51.net/uploads/img/202305/b8200a0bc0f08cd92d47e2d7bd52007c.jpg"></p>
<p>
nginx安装完成了，那么该配置php-fpm了。让nginx与php联动起来。</p>
<p>
打开php-fpm配置文件</p>
<div class="jb51code">
<div>
<div class="syntaxhighlighterbash" id="highlighter_264300">
<div class="toolbar">
<span>?</span>
</div>
<table border="0" cellpadding="0" cellspacing="0"><tbody><tr>
<td class="gutter">
<div class="line number1 index0 alt2">
1</div>
</td>
<td class="code">
<div class="container">

<code class="bash functions">sudo</code> <code class="bash functions">vi</code> <code class="bash plain">/etc/php-fpm</code><code class="bash plain">.d</code><code class="bash plain">/www</code><code class="bash plain">.conf</code>
</div>
</div>
</td>
</tr></tbody></table>
</div>
</div>
</div>
<p>
修改以下内容（这里查找配置项时，可以使用斜杠加要查找的关键字回车查找，如下图所示）</p>
<div class="jb51code">
<div>
<div class="syntaxhighlighterbash" id="highlighter_938196">
<div class="toolbar">
<span>?</span>
</div>
<table border="0" cellpadding="0" cellspacing="0"><tbody><tr>
<td class="gutter">
<div class="line number1 index0 alt2">

<div class="line number2 index1 alt1">

<div class="line number3 index2 alt2">
3</div>
</td>
<td class="code">
<div class="container">
<div class="line number1 index0 alt2">
<code class="bash plain">listen.owner = nginx</code>
</div>
<div class="line number2 index1 alt1">
<code class="bash plain">listen.group = nginx</code>
</div>
<div class="line number3 index2 alt2">
<code class="bash plain">listen.mode = 0666</code>
</div>
</div>
</td>
</tr></tbody></table>
</div>
</div>
</div>
<p>

<p>
最后，把三个参数修改完成后:wq退出然后重启php-fpm服务</p>
<div class="jb51code">
<div>
<div class="syntaxhighlighterbash" id="highlighter_431847">
<div class="toolbar">
<span>?</span>
</div>

</div>
</div>
</td>
</tr></tbody></table>
</div>
</div>
</div>
<p>
然后，我们来修改nginx的配置，先使用find命令查找配置文件位置，我的配置文件位置如下图</p>
<div class="jb51code">
<div>
<div class="syntaxhighlighterbash" id="highlighter_852784">
<div class="toolbar">
<span>?</span>
</div>
<table border="0" cellpadding="0" cellspacing="0"><tbody><tr>
<td class="gutter">

</td>
<td class="code">
<div class="container">
<div class="line number1 index0 alt2">
<code class="bash functions">find</code> <code class="bash plain">/ -name nginx.conf</code>
</div>
</div>
</td>
</tr></tbody></table>
</div>
</div>
</div>
<p>

<p>
然后，使用vi 命令进入查看，在最后一行发现这个配置文件又引入了其他配置文件。</p>
<div class="jb51code">
<div>
<div class="syntaxhighlighterbash" id="highlighter_799892">
<div class="toolbar">

<p>
再次进入这个目录发现配置文件如下图</p>
<p>

<p>
使用vi命令修改它</p>
<div class="jb51code">
<div>
<div class="syntaxhighlighterbash" id="highlighter_104825">
<div class="toolbar">
<span>?</span>
</div>
<table border="0" cellpadding="0" cellspacing="0"><tbody><tr>

<code class="bash functions">vi</code> <code class="bash plain">default.conf</code>
</div>
</div>
</td>
</tr></tbody></table>
</div>
</div>
</div>
<p>
在localhost下加上同级，如下图所示</p>
<div class="jb51code">
<div>
<div class="syntaxhighlighterbash" id="highlighter_271710">
<div class="toolbar">
<span>?</span>

<p>

<p>
修改保存之后，使用nginx -t命令确认格式无错误，后重启nginx。如下图所示</p>
<div class="jb51code">
<div>
<div class="syntaxhighlighterbash" id="highlighter_601397">
<div class="toolbar">
<span>?</span>
</div>
<table border="0" cellpadding="0" cellspacing="0"><tbody><tr>
<td class="gutter">
<div class="line number1 index0 alt2">

</td>
<td class="code">
<div class="container">
<div class="line number1 index0 alt2">
<code class="bash plain">nginx -tnginx -s reload</code>
</div>
</div>
</td>
</tr></tbody></table>
</div>
</div>
</div>
<p>
之后，在刚刚设置的php目录下，新建一个php文件用于测试。</p>
<p>
在/var/www/html建立index.php</p>
<p>
<?php</p>
<p>
phpinfo();</p>
<p>
<img style="max-width:100%!important;height:auto!important;"title="CentOS7 LNMP+phpmyadmin环境搭建 第二篇LNMP环境搭建教程" alt="CentOS7 LNMP+phpmyadmin环境搭建 第二篇LNMP环境搭建教程" src="https://zhuji.jb51.net/uploads/img/202305/0b62b810cc9d1d570c2cbf5ccad62d47.jpg"></p>
<p>
然后，我们访问localhsot/index.php如果看到以下画面，则说明我们的nginx php 已经关联上了。</p>
<p>

<p>
至此，lnmp已经按装完成，这篇博客的篇幅已经够长了，下篇博客，我们再来安装phpmyadmin。</p>
<p>
以上就是本文的全部内容，希望对大家的学习有所帮助，也希望大家多多支持服务器之家。</p>
