php7和apache与CentOS7和mysql5.7的配置教程详解
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
