php7和apache与CentOS7和mysql5.7的配置教程详解

这篇文章主要介绍了CentOS7+apache+php7+mysql5.7配置教程详解,需要的朋友可以参考下

 yum upgrade
yum install net-tools

安装apache

关闭SELinux

编辑器打开 etc/selinux/config 文件，找到 SELINUX=enforcing 字段，将其改成 SELINUX=disabled ，并重启设备。

yum -y install httpd mod_ssl

配置防火墙

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

开机启动

systemctl start httpd
systemctl enable httpd

终端输入如下指令检查httpd的运行状态

sudo systemctl status httpd

安装PHP7

添加源

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

安装

yum install php70w

安装mysql5.7

1.安装wget

  yum -y install wget

2.安装源

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

3.安装mysql

  yum install mysql-server

4.启动mysql服务

 systemctl start mysqld

5.查看MySQL的启动状态

 systemctl status mysqld

6.开机启动

 systemctl enable mysqld
  systemctl daemon-reload

7.修改root本地登录密码

查找mysql生成的随机密码

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

修改密码，注意：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

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

8.配置默认编码为utf8

修改/etc/my.cnf配置文件，在[mysqld]下添加编码配置

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

9.配置mysql远程连接

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

然后用以下命令查看哪些用户和host可以访问，%代表任意ip地址

select user,host from user;

防火墙添加3306端口

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

10.mysql忘记密码

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

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

3.

mysql> update mysql.user set authentication_string=password('123qwe') where user='root' and Host = 'localhost';
  mysql> flush privileges;
  mysql> quit;

 将/etc/my.cnf文件还原，重新启动mysql:service mysql restart,这个时候可以使用mysql -u root -p'123qwe'进入了

 mysql>SET PASSWORD = PASSWORD('newpasswd'); 设置新密码
