搭建LAMP环境以及shell脚本搭建(yum安装)

CentOS搭建LAMP

1、配置防火墙
打开防火墙配置文件

vi /etc/sysconfig/iptables

 

--------------------------

-A INPUT -m state –state NEW -m tcp -p tcp –dport 22 -j ACCEPT
-A INPUT -m state –state NEW -m tcp -p tcp –dport 80 -j ACCEPT #允许80端口通过防火墙
-A INPUT -m state –state NEW -m tcp -p tcp –dport 3306 -j ACCEPT #允许3306端口通过防火墙

--------------------------
设置80、3306端口可以通过防火墙

重启防火墙

/etc/init.d/iptables restart #最后重启防火墙使配置生效或者是【service iptables restart 】

 

2、安装Apache
卸载自带httpd:

 yum -y remove httpd

 

 

安装

yum -y install httpd httpd-devel 

 

安装完成后，启动apache ,执行命令：

service httpd start #或者是【/etc/init.d/httpd start】

 

设为开机启动，执行命令:

chkconfig httpd on

 

 

3.安装mysql
卸载自带mysql

yum -y remove mysql mysql-server mysql-libs compat-mysql51

 

安装

yum -y remove mysql mysql-server mysql-libs compat-mysql51

 

停止mysql，执行命令：

mysqld_safe --user=mysql --skip-grant-tables --skip-networking &

 

进入mysql

mysql -u root mysql

 

mysql的使用
----------------------------------

mysql>USE mysql; 
mysql> UPDATE user SET Password=PASSWORD('123') where USER='root'; #修改新密码为123
mysql> FLUSH PRIVILEGES;
mysql> quit;

 

----------------------------------
重启mysql

service mysqld restart #或者是【/etc/init.d/mysql restart】

 

再次重设mysql的密码

mysql -uroot -p

 

Enter password: <输入新设的密码newpassword>

 

4、安装php

yum -y remove php php-mysql php-common php-gd php-mbstring php-mcrypt php-devel php-xml 
yum -y install php php-mysql php-common php-gd php-mbstring php-mcrypt php-devel php-xml 

 

重启http服务

service httpd start #或者是【/etc/init.d/httpd start】

 

 

5、测试

vi /var/www/html/test.php

 

写入内容
-------------------------
<?php
phpinfo();
?>
-------------------------
重启http服务

/etc/init.d/httpd restart
