lamp安装

8. lamp安装 contos 7.0

作者： 1944988418@qq.com
 CentOS 7.0默认使用的是firewall作为防火墙，这里改为iptables防火墙。
#停止firewall服务
systemctl stop firewalld.service
#禁止firewall开机启动
systemctl disable firewalld.service
 
#安装
yum install iptables-services
#编辑防火墙配置文件
vi /etc/sysconfig/iptables
加入红色的两行代码，请注意位置一定要对应。
 
# Firewall configuration written by system-config-firewall
# Manual customization of this file is not recommended.
*filter
:INPUT ACCEPT [0:0]
:FORWARD ACCEPT [0:0]
:OUTPUT ACCEPT [0:0]
-A INPUT -m state --state ESTABLISHED,RELATED -j ACCEPT
-A INPUT -p icmp -j ACCEPT
-A INPUT -i lo -j ACCEPT
-A INPUT -m state --state NEW -m tcp -p tcp --dport 22 -j ACCEPT

-A INPUT -j REJECT --reject-with icmp-host-prohibited
-A FORWARD -j REJECT --reject-with icmp-host-prohibited
COMMIT
:wq! #保存退出
#最后重启防火墙使配置生效
systemctl restart iptables.service
#设置防火墙开机启动
systemctl enable iptables.service
3. 关闭seinux
#修改配置文件
vi /etc/selinux/config
#SELINUX=enforcing #注释掉
#SELINUXTYPE=targeted #注释掉
SELINUX=disabled #增加
:wq! #保存退出
#使配置立即生效
setenforce 0

　　2.2 开启mysql服务，并设置开机启动，检查mysql状态

[root@nmserver-7 ~]# systemctl start mariadb
[root@nmserver-7 ~]# systemctl enable mariadb
Created symlink from /etc/systemd/system/multi-user.target.wants/mariadb.service to /usr/lib/systemd/system/mariadb.service.

　　2.3 数据库安全设置

[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 MariaDBinstallation should now be secure.
 
Thanks for using MariaDB!
 

　　2.4 登陆数据库测试

[root@nmserver-7 ~]# mysql -uroot -p
Enter password:
Welcome to the MariaDB monitor. Commands end with ; or \g.
Your MariaDB connection id is 11
Server version: 5.5.52-MariaDB MariaDB Server
 
Copyright (c) 2000, 2016, Oracle, MariaDB Corporation Ab and others.
 
Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.
 
MariaDB [(none)]> show databases;

| mysql |
| performance_schema |

MariaDB [(none)]>
 

3、安装PHP

　　3.1 安装php

[root@nmserver-7 ~]# yum -y install php
[root@nmserver-7 ~]# rpm -ql php
/etc/httpd/conf.d/php.conf
/etc/httpd/conf.modules.d/10-php.conf
/usr/lib/httpd/modules/libphp5.so
/usr/share/httpd/icons/php.gif
/var/lib/php/session
 

　　3.2 将php与mysql关联起来

[root@nmserver-7 ~]# yum install php-mysql
[root@nmserver-7 ~]# rpm -ql php-mysql
/etc/php.d/mysql.ini
/etc/php.d/mysqli.ini
/etc/php.d/pdo_mysql.ini
/usr/lib/php/modules/mysql.so
/usr/lib/php/modules/mysqli.so
/usr/lib/php/modules/pdo_mysql.so
 

　　3.3 安装常用PHP模块

[root@nmserver-7 ~]# yum install -y php-gd php-ldap php-odbc php-pear php-xml php-xmlrpc php-mbstring php-snmp php-soap curl curl-devel php-bcmath
 

　　3.4 测试PHP

给www设置最高权限  chmod -R 777 www
 
[root@nmserver-7 ~]# cd /var/www/html/
[root@nmserver-7 html]# ls
[root@nmserver-7 html]# pwd
/var/www/html
[root@nmserver-7 html]# vi info.php
 
<?php
phpinfo();
?>
~
~
~
~
~
~
~
~
:wq
 

　　3.5重启apache服务器

[root@nmserver-7 html]# systemctl restart http

　　3.6测试PHP

　　在自己电脑浏览器输入 192.168.8.9/info.php，你可以看到已经安装的模块；
 
 
 
contos6.4 升级php
 
忘记密码操作
 
、修改配置文件my.cnf 按i编辑
?
1
[root@iZ2ze14tbj23jllo85kuh1Z ~]# vim /etc/my.cnf
 
在[mysqld]中添加
?
1
skip-grant-tables
 
例如：
?
1
2
3
4
[mysqld]
**skip-grant-tables**
datadir=/var/lib/mysql
socket=/var/lib/mysql/mysql.sock
 
键盘 Esc 保存修改  :wq退出
2、重启mysql服务
?
1
service mysqld restart
 
3、用户登录
?
1
mysql -uroot -p (直接点击回车，密码为空)
 
选择数据库
?
1
use mysql;
 
下面我们就要修改密码了
以前的版本我们用的是以下修改
?
1
update user set password=password('root') where user='root';
 
但是在5.7版本中不存在password字段，所有我们要用以下修改进行重置密码
?
1
update user set authentication_string=password('123456') where user='root';
 
执行
?
1
flush privileges;
 
4、退出mysql
?
1
quit;
 
5、将最开始修改的配置文件my.cnf中的skip-grant-tables删除
