开机启动Apache
chkconfig --list | grep httpd

[root@localhost 桌面]# chkconfig --list |grep httpd
httpd 0:关闭 1:关闭 2:关闭 3:关闭 4:关闭 5:关闭 6:关闭

chkconfig httpd on 	设置httpd每次开机自己启动，但并不现在就启动。运行级别2345都为on
service httpd start 	现在启动httpd服务，但是下次开机不会自动启动

[root@localhost 桌面]# chkconfig --list |grep httpd
httpd 0:关闭 1:关闭 2:启用 3:启用 4:启用 5:启用 6:关闭
service httpd status
[root@localhost 桌面]# service httpd status
httpd (pid 3346) 正在运行...
iptables中开放80端口
此时只能虚拟机本机访问80端口，因为iptables中没有开放80端口
此时iptables的运行级别2345都是on
关闭iptables
关闭命令： service iptables stop
永久关闭防火墙：chkconfig iptables off
查看iptables状态 ：service iptables status

查看当前iptables状态
	iptables -L -n
	service iptables status

默认iptables中只开放了22端口
/sbin/iptables -I INPUT -p tcp --dport 80 -j ACCEPT
/etc/rc.d/init.d/iptables save  或者 service iptables save #保存配置 
/etc/rc.d/init.d/iptables restart 或者 service iptables restart #重启服务

[root@localhost 桌面]# yum list installed | grep mysql
mysql-libs.i686 5.1.66-2.el6_3 @anaconda-CentOS-201303020136.i386/6.4

安装命令
yum install mysql
yum install mysql-server
yum install mysql-devel
(yum -y install mysql-server mysql mysql-devel)
安装过程没有出现输入用户名密码的地方，也没有远程访问的设置

安装成功后检查

[root@localhost 桌面]# rpm -qa |grep mysql
mysql-libs-5.1.73-7.el6.i686
mysql-devel-5.1.73-7.el6.i686
mysql-5.1.73-7.el6.i686

开机启动MySQL
service mysqld status
chkconfig --list | grep mysqld
chkconfig mysqld on
service mysqld start

查看端口：netstat -tnlp,显示3306 已经开启
查看iptables开放端口：service iptables status

ptables中添加3306端口
/sbin/iptables -I INPUT -p tcp --dport 3306 -j ACCEPT
/etc/rc.d/init.d/iptables save  或者 service iptables save #保存配置 
/etc/rc.d/init.d/iptables restart 或者 service iptables restart #重启服务

[root@localhost 桌面]# service iptables status

root 可以空密码登陆
匿名账户也可以登陆
设置root密码

mysql -u root root空密码登陆
select user,host,password from mysql.user; 查看用户信息

设置root用户的密码
set password for root@localhost=password ('在这里填入root密码');
set password for root@127.0.0.1=password ('在这里填入root密码');
set password for root@localhost.localdomain=password ('在这里填入root密码'); 绿色的是主机名

匿名账户登录

删除匿名账户登录

删除匿名登录账号
delete from mysql.user where user='';
刷新
flush privileges;

允许远程连接

CREATE USER 'root'@'%' IDENTIFIED BY '您的密码'; ← 增加root用户指定可以任意IP登录，如果想限制只能让指定IP登录请把%替换成IP地址

GRANT ALL PRIVILEGES ON * . * TO 'root'@'%' IDENTIFIED BY '你的密码' WITH GRANT OPTION MAX_QUERIES_PER_HOUR 0 MAX_CONNECTIONS_PER_HOUR 0 MAX_UPDATES_PER_HOUR 0 MAX_USER_CONNECTIONS 0 ; ← 给新添加的root增加权限

刷新
flush privileges;
