1、如果是在弹性云服务器上部署就不用更换yum源，虚拟机上面模拟首先更换yum。

https://developer.aliyun.com/mirror/              ##阿里镜像源

2、开始安装LAMP服务

[root@localhost ~]# yum -y install httpd php php-fpm php-server php-mysql       ##分别安装httpd   php  php-server php-fpm  php-mysql等服务

3、重启httpd和php

[root@node-0002 ~]# nohup python -m SimpleHTTPServer 80 > /dev/null 2>&1 &      开放80端口
[1] 8110
[root@node-0002 ~]#  curl 127.0.0.1:80
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 3.2 Final//EN"><html>
<title>Directory listing for /</title>
<body>
<h2>Directory listing for /</h2>
<hr>
<ul>
<li><a href=".bash_history">.bash_history</a>
<li><a href=".bash_logout">.bash_logout</a>
<li><a href=".bash_profile">.bash_profile</a>
<li><a href=".bashrc">.bashrc</a>

<li><a href=".ssh/">.ssh/</a>
<li><a href=".tcshrc">.tcshrc</a>
</ul>
<hr>
</body>
</html>
[root@node-0002 ~]# touch SERVER1      ##创建一个文件



在这里出现了一个问题：（我们来一起看一下）
httpd服务启动不了
[root@node-0002 ~]# netstat -ntulp |grep 80         ##查看端口被python占用
tcp        0      0 0.0.0.0:80              0.0.0.0:*               LISTEN      8110/python  
解决：
[root@node-0002 ~]# ps -ef|grep python 
root       654     1  0 18:16 ?        00:00:00 /usr/bin/python2 -Es /usr/sbin/tuned -l -P
root      8110  8081  0 18:32 pts/0    00:00:28 python -m SimpleHTTPServer 80
root     18341  8081  0 19:43 pts/0    00:00:00 grep --color=auto python
[root@node-0002 ~]# kill -9 8110
再次查看端口：
[root@node-0002 ~]# netstat -ntulp |grep 80
[1]+  Killed                  nohup python -m SimpleHTTPServer 80 > /dev/null 2>&1

重启HTTP和php服务
[root@localhost ~]# systemctl restart httpd
[root@localhost ~]# systemctl enable httpd           ##重启http
Created symlink from /etc/systemd/system/multi-user.target.wants/httpd.service to /usr/lib/systemd/system/httpd.service.
[root@localhost ~]# systemctl restart php-fpm
[root@localhost ~]# systemctl enable php-fpm      ##重启php
Created symlink from /etc/systemd/system/multi-user.target.wants/php-fpm.service to /usr/lib/systemd/system/php-fpm.service.
[root@localhost ~]# 

[root@localhost ~]#echo "<?php echo phpinfo(); ?>" >/var/www/html/index.php     #编写php代码并查看 web界面
[root@localhost ~]# cat /var/www/html/index.php 
<?php echo phpinfo(); ?>
[root@localhost ~]# chmod -R 777 /var/www/html
[root@localhost ~]# systemctl restart httpd

4、web界面验证http是否启动

如果不能访问：

（1）弹性云主机去安全组添加：http 80端口

（2）虚拟机里面的话：

[root@localhost ~]# systemctl start firewalld       ##重启防火墙
[root@localhost ~]# firewall-cmd --list-ports       ##查看端口
          ##这里显示没有端口开启

[root@localhost ~]# firewall-cmd --zone=public --add-port=80/tcp --permanent        ##开启tcp/80这个端口
success
[root@localhost ~]#  firewall-cmd --reload         ##启动端口
success
[root@localhost ~]# firewall-cmd --list-ports
80/tcp             ##再次查看就会发现80端口已经开启

5、卸载Mariadb数据库（卸载mariadb数据库是为了防止密码冲突）

[root@localhost ~]# yum -y remove mariadb-server
已加载插件：fastestmirror
Loading mirror speeds from cached hostfile
 * base: mirrors.aliyun.com
 * extras: mirrors.aliyun.com
 * updates: mirrors.aliyun.com                    ##我这里用的是虚拟机源也是阿里的镜像源

6、重启Mariadb并重置密码：

[root@localhost ~]# wget http://dev.mysql.com/get/mysql57-community-release-el7-8.noarch.rpm
[root@localhost ~]# yum -y install mysql57-community-release-el7-8.noarch.rpm 
Loaded plugins: fastestmirror
[root@localhost ~]# yum -y install mysql-community-server
Loaded plugins: fastestmirror
Loading mirror speeds from cached hostfile
[root@localhost ~]# systemctl restart mysqld
[root@localhost ~]# systemctl enable mysqld
[root@localhost ~]# grep -Eo "for root@localhost:.*" /var/log/mysqld.log |sed -r "s/(for.*localhost:)(.*)/\2/"
 gc<F_aDZR5r?


[root@localhost ~]# mysql_secure_installation   ##初始化数据库密码

Securing the MySQL server deployment. 

Enter password for user root: gc<F_aDZR5r?

The existing password for the user account root has expired. Please set a new password.

New password: Huawei@123

Re-enter new password: Huawei@123

The 'validate_password' plugin is installed on the server.
The subsequent steps will run with the existing configuration
of the plugin.
Using existing password for root.

Estimated strength of the password: 100 
Change the password for root ? ((Press y|Y for Yes, any other key for No) : n
 ... skipping.
By default, a MySQL installation has an anonymous user,
allowing anyone to log into MySQL without having to have
a user account created for them. This is intended only for
testing, and to make the installation go a bit smoother.
You should remove them before moving into a production
environment.

Remove anonymous users? (Press y|Y for Yes, any other key for No) : y
Success.


Normally, root should only be allowed to connect from
'localhost'. This ensures that someone cannot guess at
the root password from the network.

Disallow root login remotely? (Press y|Y for Yes, any other key for No) : n

... skipping.
By default, MySQL comes with a database named 'test' that
anyone can access. This is also intended only for testing,
and should be removed before moving into a production
environment.


Remove yest database and access to it? (Press y|Y for Yes, any other key for No) : y
 - Dropping test database...
Success.

 - Removing privileges on test database...
Success.

Reloading the privilege tables will ensure that all changes
made so far will take effect immediately.

Reload privilege tables now? (Press y|Y for Yes, any other key for No) : y
Success.

All done! 
[root@localhost ~]# 
[root@localhost ~]#

7、登入数据库设置权限

[root@localhost ~]# mysql -uroot -pHuawei@123

-bash: wget: 未找到命令               ##没有安装wget这个命令
