Alibaba Cloud centOS7 installs MYSQL plus PHP plus Apache environment

The content shared in this article is the installation of MYSQL plus PHP plus Apache environment on Alibaba Cloud centOS7. Now I share it with everyone. Friends in need can refer to the content of this article.

1.Install apache:

##

yum install httpd httpd-devel

Start apache:

##

systemctl start httpd.service
设置开机自动启动：systemctl enable httpd.service

yum install php php-devel

systemctl restart httpd.service

<?php phpinfo(); ?>

Then access this file, you can see some information about PHP. The path of the php.ini configuration file can be seen on this page

Install php extension

yum install php-mysql php-gd php-imap php-ldap php-odbc php-pear php-xml php-xmlrpc

systemctl restart httpd.service

3. Install MYSQL and set up remote access

##

① yum install mysql

② yum install mysql-server

③ yum install mysql-devel

如果第②步没有可用的包则执行下面五个步骤(有则忽略)：

                                                                                                                                                                           The wget command #: Download mysql's repo source

## Step 3: Install mysql-community- release-el7-5.noarch.rpm package

            [root@master ~]# yum -y install wget

            [root@master ~]# wget http://repo.mysql.com/mysql-community-release-el7-5.noarch.rpm

会获得两个mysql的yum repo源：/etc/yum.repos.d/mysql-community.repo，/etc/yum.repos.d/mysql-community-source.repo。

第五步：安装mysql

            [root@master ~]# yum install mysql-server

然后，重启服务：

$ service mysqld restart

接下来登录重置密码：

$ mysql -u root
mysql > use mysql;
mysql > update user set password=password('123456') where user='root';
mysql > exit;

5. 开放3306端口

[plain] view plain copy

1. service iptables start/stop

   Copy after login

会报错Failed to start iptables.service: Unit iptables.service failed to load: No such file or directory.

CentOS 7或RHEL 7或Fedora中防火墙由firewalld来管理

firewall-cmd --zone= public --query-port=80/tcp

firewall-cmd --permanent --zone=public --add-port=3306/tcp

如果firewall is not running

通过systemctl start firewalld开启防火墙，没有任何提示即开启成功。

firewall-cmd --permanent --zone=public --add-port=3306/tcp，提示success，表示设置成功，这样就可以继续后面的设置了。

$ sudo vim /etc/sysconfig/iptables

添加以下内容：

-A INPUT -p tcp -m state --state NEW -m tcp --dport 3306 -j ACCEPT

保存后重启防火墙：

$ sudo service iptables restart

6. 创建普通用户并授权

示例（使用root用户登录）：

mysql > use mysql;

mysql > grant all privileges on *.* to 'root'@'%' identified by '123456';mysql > flushn privileges;
