yum upgradeyum install net-tools

安裝apache

關閉SELinux

編輯器打開 etc/selinux/config 文件，找到 SELINUX=enforcing 字段，將其改成 SELINUX=disabled ，并重啟設備。

yum -y install httpd mod_ssl

配置防火墻

firewall-cmd --permanent --add-port=80/tcpfirewall-cmd --permanent --add-port=443/tcpfirewall-cmd --reload

開機啟動

systemctl start httpdsystemctl enable httpd

終端輸入如下指令檢查httpd的運行狀態

sudo systemctl status httpd

安裝PHP7

添加源

rpm -Uvh https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpmrpm -Uvh https://mirror.webtatic.com/yum/el7/webtatic-release.rpm

安裝

yum install php70w

安裝mysql5.7

1.安裝wget

  yum -y install wget

2.安裝源

 wget http://dev.mysql.com/get/mysql57-community-release-el7-8.noarch.rpm  rpm -ivh mysql57-community-release-el7-8.noarch.rpm

3.安裝mysql

  yum install mysql-server

4.啟動mysql服務  

 systemctl start mysqld

5.查看MySQL的啟動狀態   

 systemctl status mysqld

6.開機啟動  

 systemctl enable mysqld  systemctl daemon-reload

7.修改root本地登錄密碼

    查找mysql生成的隨機密碼  

 grep 'temporary password' /var/log/mysqld.log  mysql -uroot -p

    修改密碼，注意：mysql5.7默認安裝了密碼安全檢查插件（validate_password），默認密碼檢查策略要求密碼必須包含：大小寫字母、數字和特殊符號，并且長度不能少于8位。否則會提示ERROR 1819 (HY000): Your password does not satisfy the current policy requirements錯誤

  ALTER USER 'root'@'localhost' IDENTIFIED BY 'MyNewPass4!';

8.配置默認編碼為utf8

    修改/etc/my.cnf配置文件，在[mysqld]下添加編碼配置   

 [mysqld]  character_set_server=utf8  init_connect='SET NAMES utf8'

9.配置mysql遠程連接

  mysql -uroot -p  use mysql;  Grant all on *.* to 'root'@'%' identified by 'root用戶的密碼' with grant option;flush privileges;

然后用以下命令查看哪些用戶和host可以訪問，%代表任意ip地址

select user,host from user;

防火墻添加3306端口

firewall-cmd --zone=public --add-port=3306/tcp --permanentfirewall-cmd --reload

10.mysql忘記密碼

1.修改MySQL的配置文件（默認為/etc/my.cnf）,在[mysqld]下添加一行skip-grant-tables

2.service mysqld restart后，即可直接用mysql進入

3.
