YUM方式安装LAMP PHP7.4 MYSQL8.0

在centos7中使用yum源安装LAMP
PHP7.4+MYSQL8
使用腾讯云的源安装LAMP
CENTOS8+HTTP2.4+MYSQL8+PHP74
下载新的 CentOS-Base.repo 到 /etc/yum.repos.d/
CentOS 8

wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.cloud.tencent.com/repo/centos8_base.repo
CentOS 7

wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.cloud.tencent.com/repo/centos7_base.repo

更新源以后，yum update 升级一下各软件

一、安装HTTP,
yum install httpd httpd-devel mod_ssl httpd-manual mod_perl -y
systemctl restart httpd && systemctl enable httpd
查看默认网页

二、安装php74
如果安装php74要使用remi源
yum install http://rpms.remirepo.net/enterprise/remi-release-7.rpm
2.安装YUM管理工具
yum install yum-utils
yum install php74 php74-php php74-php-gd php74-php-pdo php74-php-mbstring php74-php-cli php74-php-fpm php74-php-mysqlnd

####如果安装php72
yum -y install --enalberepo=remi-php72 php72w php72w-cli php72w-common php72w-devel php72w-embedded php72w-fpm php72w-gd php72w-mbstring php72w-mysqlnd php72w-opcache php72w-pdo php72w-xml php72w-process php-mysqli

三、安装mysql8
yum localinstall https://dev.mysql.com/get/mysql80-community-release-el7-4.noarch.rpm

yum install mysql-server

systemctl start mysqld && systemctl enable mysqld

启动mysqld
service mysqld start
查看初始化密码
grep ‘password’ /var/log/mysqld.log

mysql -uroot -p"上面查看到的密码"
修改密码
ALTER USER ‘root’@‘localhost’ IDENTIFIED WITH mysql_native_password BY ‘你的密码’;
例如：
ALTER USER ‘root’@‘localhost’ IDENTIFIED WITH mysql_native_password BY ‘Cgy@1984’;
FLUSH PRIVILEGES;

mysql8中必须要先创建一个用户，然后再进行授权，可以说是更加的规范了。

见官方说明：https://dev.mysql.com/doc/refman/8.0/en/adding-users.html

以下是创建和授权的命令：[更请参考官网的示例]

mysql> create user ‘newuser’@’%’ identified by ‘mima’;

mysql> grant all privileges on . to ‘username’@’%’ with grant option;

mysql> flush privileges;
