CentOS 7.3搭建LAMP

服务器 CentOS Linux release 7.3.1611 (Core) x64

安装

Apache2.4

[root]# yum install httpd
[root]# systemctl enable httpd.service 加入开机启动
[root]# systemctl start httpd 启动Apache
[root]# systemctl status httpd 查看状态

PHP7

添加RPM源
[root]# rpm -Uvh https://mirror.webtatic.com/yum/el7/webtatic-release.rpm
[root]# rpm -Uvh https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm

安装php以及常用扩展

[root]# yum install php70w php70w-common php70w-fpm php70w-opcache php70w-gd php70w-mysqlnd php70w-mbstring php70w-pecl-redis php70w-pecl-memcached php70w-devel


安装mysql之前先安装wget这个工具，命令yum install wget

Mysql 5.7[也可以使用MariaDB]

添加RPM源
[root]# wget http://dev.mysql.com/get/mysql57-community-release-el7-8.noarch.rpm

安装源 -ivh显示安装进度
[root]# rpm -ivh mysql57-community-release-el7-8.noarch.rpm

安装Mysql
[root]# yum install mysql-server

[root]# systemctl start mysqld.启动mysql服务
[root]# systemctl status mysqld查看MySQL的启动状态

.开机启动
[root]# systemctl enable mysqld
[root]# systemctl daemon-reload

修改Mysql生成的随机密码
[root]# grep 'temporary password' /var/log/mysqld.log
[root]# mysql -uroot -p

新密码须包含数字、大小写字母和特殊字符，否则通不过安全策略
mysql > ALTER USER 'root'@'localhost' IDENTIFIED BY 'newPassWord!';

配置默认编码

/etc/my.cnf

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


允许root用户远程连接Mysql
mysql > Grant all on *.* to 'root'@'%' identified by 'password' with grant option;
mysql > flush privileges;//一定要刷新

Mysql忘记密码
修改/etc/my.cnf
在[mysqld]下添加一行 skip-grant-tables

[root]# service mysqld restart
[root]# mysql
mysql> update mysql.user set authentication_string=password('newpassword') where user='root' and Host = 'localhost';
mysql> flush privileges;

为了安全，将/etc/my.cnf的修改恢复，重新启动mysql

设置新密码
mysql>update user set authentication_string=password('password') where user='root';

---

Mysql5.7密码字段已更改
原来的密码字段password变更成authentication_string
