最近在新的服务器上安装了lamp环境，现在整理一下方便下次安装
一、安装apache
1、centos7默认自带（Apache2.4.6）版本
yum -y install httpd
2、开启apache服务
systemctl start httpd.service
3、设置apache服务开机启动
systemctl enable httpd.service
4、打开浏览器输入IP地址，页面出现Testing 123..等字样，apache服务安装成功
二、安装php
1、默认centos7 自带的是php5.4版本，升级php5.6。不升级只有yum 安装
2、升级php5.6
# yum install epel-release
# rpm -ivh http://rpms.famillecollet.com/enterprise/remi-release-7.rpm
3、安装php5.6
# yum install --enablerepo=remi --enablerepo=remi-php56 php php-opcache php-devel php-mbstring php-mcrypt php-mysqlnd php-phpunit-PHPUnit php-pecl-xdebug php-pecl-xhprof php-gd php-redis
4、安装php-fpm
yum install --enablerepo=remi --enablerepo=remi-php56 php-fpm
5、重启apache
systemctl restart httpd.service
6、验证是否成功
在/var/www/html地址里新建一个index.php页面
index.php页面写上
<?php phpinfo();?>
浏览器地址输入ip/index.php，会出现php的配置信息，安装成功
三、安装数据库
一、方法一安装mysql
1、官网下载mysql
# wget http://dev.mysql.com/get/mysql-community-release-el7-5.noarch.rpm
# rpm -ivh mysql-community-release-el7-5.noarch.rpm
2、安装mysql
# yum install mysql-community-server
3、安装成功后重启mysql服务
# service mysqld restart
4、修改信息
初次安装mysql，root是没有密码的。需要设置密码
# mysql -u root
mysql>set password for 'root'@'localhost' =password('password');
mysql>exit;
二、方法二安装mariadb
1、centos7自带mariadb可以直接安装
yum install mariadb mariadb-server mariadb-libs mariadb-devel
2、开启服务
systemctl start mariadb
3、设置开机自启动
systemctl enable mariadb
4、检查状态
systemctl status mariadb
5、安全设置
[root@nmserver-7 ~]# mysql_secure_installation
NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MariaDB
SERVERS IN PRODUCTION USE! PLEASE READ EACH STEP CAREFULLY!
In order to log into MariaDB to secure it, we'll need the current
password for the root user. If you've just installed MariaDB, and
you haven't set the root password yet, the password will be blank,
so you should just press enter here.
Enter current password for root (enter for none):
OK, successfully used password, moving on...
Setting the root password ensures that nobody can log into the MariaDB
root user without the proper authorisation.
Set root password? [Y/n] y
New password:
Re-enter new password:
Password updated successfully!
Reloading privilege tables..
... Success!
By default, a MariaDB installation has an anonymous user, allowing anyone
to log into MariaDB without having to have a user account created for
them. This is intended only for testing, and to make the installation
go a bit smoother. You should remove them before moving into a
production environment.
Remove anonymous users? [Y/n] y
... Success!
Normally, root should only be allowed to connect from 'localhost'. This
ensures that someone cannot guess at the root password from the network.
Disallow root login remotely? [Y/n] n
... skipping.
By default, MariaDB comes with a database named 'test' that anyone can
access. This is also intended only for testing, and should be removed
before moving into a production environment.
Remove test database and access to it? [Y/n] y
- Dropping test database...
... Success!
- Removing privileges on test database...
... Success!
Reloading the privilege tables will ensure that all changes made so far
will take effect immediately.
Reload privilege tables now? [Y/n] y
... Success!
Cleaning up...
All done! If you've completed all of the above steps, your MariaDB
installation should now be secure.
Thanks for using MariaDB!
6、登录测试
[root@nmserver-7 ~]# mysql -uroot -p
Enter password:
