分享一下我老师大神的人工智能教程吧。零基础！通俗易懂！风趣幽默！还带黄段子！希望你也加入到我们人工智能的队伍中来！http://www.captainbed.net

1.获取PHP安装文件： downloads 或直接下载 php-5.5.9.tar.gz

获取安装php需要的支持文件： libxml2 或直接下载 libxml2-2.9.1.tar.gz

2.安装libxml2

tar zxvf libxml2-2.9.1.tar.gz
cd libxml2-2.6.32./configure --prefix=/usr/local/libxml2
make
make install

如果安装成功以后，在/usr/local/libxml2/目录下将生成bin、include、lib、man和share五个目录。在后面安装PHP5源代码包的配置时，会通过在configure命令的选项中加上"--with-libxml-dir=/usr/ local/libxml2"选项，用于指定安装libxml2库文件的位置。

3.安装php5

#tar zvxf php-5.3.8.tar.gz

#cd php-5.3.8
#./configure \
--prefix=/usr/local/php \
--with-mysql=/usr/local/mysql \
--with-apxs=/usr/local/apache2/bin/apxs --with-libxml-dir=/usr/local/libxml2
#make
#make install

4.重新配置apache2让他支持php

配置 httpd.conf 让apache支持PHP：

　　# vi /usr/local/apache/conf/httpd.conf

　　找到 AddType application/x-gzip .gz .tgz 在其下添加如下内容

　　AddType application/x-httpd-php .php (.前面有空格)

　　AddType application/x-httpd-php-source .phps (.前面有空格)

然后CPOPY PHP的配置文件

　　cp php-5.3.8/php.ini.dist /usr/local/php/lib/php.ini

（如果没有php.ini.dist 则把php.ini-development php.ini-production中的任何一个重命名为php.ini.dist即可。）

　　修改php.ini文件 register_globals = On

重启apache

　　service apache restart

5.测试php是否成功安装

写一个php测试页info.php，放到apache2/htdocs中。

<?php

phpinfo();

?>;

在浏览器中输入：服务器地址/info.php

如果能正常显示出php的信息，则说明Apche+Mysql+PHP安装成功！

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

CentOS 5.5使用yum来安装LAMP

1. 换源，使用sohu安装源
1.1 备份CentOS-Base.repo
cd /etc/yum.repos.d/
cp CentOS-Base.repo CentOS-Base.repo.bak
1.2 替换源
用vi打开CentOS-Base.repo，并将内容清空，然后将下面的内容复制进去，并保存。
# CentOS-Base.repo
#
# This file uses a new mirrorlist system developed by Lance Davis for CentOS.
# The mirror system uses the connecting IP address of the client and the
# update status of each mirror to pick mirrors that are updated to and
# geographically close to the client. You should use this for CentOS updates
# unless you are manually picking other mirrors.
#
# If the mirrorlist= does not work for you, as a fall back you can try the
# remarked out baseurl= line instead.
#
#
[base]
name=CentOS-$releasever - Base
baseurl=http://mirrors.sohu.com/centos/$releasever/os/$basearch/
gpgcheck=1
gpgkey=http://mirrors.sohu.com/centos/RPM-GPG-KEY-CentOS-5
#released updates

gpgcheck=1
enabled=0
gpgkey=http://mirrors.sohu.com/centos/RPM-GPG-KEY-CentOS-5
1.3更新一下 yum -y update

2. 用yum安装Apache、Mysql、PHP
2.1 安装Apache
yum install httpd httpd-devel
安装完成后，启动apache

/etc/init.d/httpd start
设为开机启动:chkconfig httpd on
2.2 安装mysql
yum install mysql mysql-server mysql-devel
完成后，启动mysql

/etc/init.d/mysqld start
2.2.2 设置mysql密码

mysql -uroot
mysql> USE mysql;
mysql> UPDATE user SET Password=PASSWORD(‘newpassword‘) WHERE user=‘root‘; FLUSH PRIVILEGES;
2.2.3 允许远程登录
mysql -u root -p
Enter Password: <your new password>
mysql>GRANT ALL PRIVILEGES ON *.* TO ‘username‘@‘%‘ IDENTIFIED BY ‘password‘ WITH GRANT OPTION; FLUSH PRIVILEGES;
完成后就能用mysql-front远程管理mysql了。
2.2.4 设为开机启动
chkconfig mysqld on
3. 安装php
yum install php php-mysql php-common php-gd php-mbstring php-mcrypt php-devel php-xml
/etc/init.d/httpd start
4. 测试一下
4.1在/var/www/html/新建个test.php文件，将以下内容写入，然后保存。
<?php
phpinfo();
?>
4.2 防火墙配置
a.添加.允许访问端口{21: ftp, 80: http}.
iptables -I RH-Firewall-1-INPUT -m state –state NEW -m tcp -p tcp –dport 21 -j ACCEPT
iptables -I RH-Firewall-1-INPUT -m state –state NEW -m tcp -p tcp –dport 80 -j ACCEPT
b.关闭防火墙{不推荐}.
service iptables stop
c.重置加载防火墙
service iptables restart
4.3然后在客户端浏览器里打开http://serverip/test.php，若能成功显示，则表示安装成功。
至此，安装完毕。感慨，yum真是太好用了。

PHP 升级

1.先查看当前php版本
#php -v

2.升级php版本
rpm --import http://repo.webtatic.com/yum/RPM-GPG-KEY-webtatic-andy

wget -P /etc/yum.repos.d/ http://repo.webtatic.com/yum/webtatic.repo

yum --enablerepo=webtatic update php mysql
升级php最好是连mysql一起升级,好了可以看到php已经升级成5.3.28

3、查看升级后的php版本

#php -v

PHP 5.3.28 (cli) (built: Dec 15 2013 17:43:05)
Copyright (c) 1997-2013 The PHP Group
Zend Engine v2.3.0, Copyright (c) 1998-2013 Zend Technologies

可以看到php的版本已经更新到5.3.X

重启 /etc/init.d/httpd restart 或 apache service httpd restart

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

升级 2（推荐）

1）预安装

yum --enablerepo=remi,remi-php55 install php-pecl-apc php-cli php-pear php-pdo php-mysqlnd php-pgsql php-pecl-mongo php-sqlite php-pecl-memcache php-pecl-memcached php-gd php-mbstring php-mcrypt php-xml

2）升级php

yum --enablerepo=remi,remi-php55 install php-opcache

Unable to load dynamic library ‘/usr/lib64/php/modules/gd.so

[root@ithomer ~]# php -v
PHP Warning: PHP Startup: Unable to load dynamic library ‘/usr/lib64/php/modules/gd.so‘ - libvpx.so.0: cannot map zero-fill pages: Cannot allocate memory in Unknown on line 0

libcurl.so.3

Error: Package: php-common-5.3.28-2.w5.x86_64 (webtatic)
Requires: libcurl.so.3()(64bit)
You could try using --skip-broken to work around the problem
You could try running: rpm -Va --nofiles --nodigest

yum install libcurl libcurl-devel

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

MySQL 升级

CentOS 5.5的源mysql目前还停留在5.0.19上，要做数据库主从的时候，必须升级到5.1以上，索性直接到5.5.36

1、安装MySQL 5.5.x的yum源：

rpm -Uvh http://repo.webtatic.com/yum/centos/5/latest.rpm

2、安装MySQL客户端的支持包：

yum install libmysqlclient15 --enablerepo=webtatic

3、卸载MySQL老版本的软件包：

yum remove mysql mysql-*

4、安装MySQL 5.5的客户端和服务端：

yum install mysql55 mysql55-server --enablerepo=webtatic

5、启动MySQL系统服务，更新数据库：

/etc/init.d/mysqld restart

mysql_upgrade -uroot -proot

升级完毕

/etc/init.d/mysqld restart

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

升级 1（推荐）

To list Old MySql
yum list installed | grep -i mysql

To remove Old MySql
yum remove mysql mysql-*

Remi Dependency on CentOS 6 and Red Hat (RHEL) 6
rpm -Uvh http://dl.fedoraproject.org/pub/epel/6/i386/epel-release-6-8.noarch.rpm
rpm -Uvh http://rpms.famillecollet.com/enterprise/remi-release-6.rpm

Install MySQL server
yum --enablerepo=remi,remi-test install mysql mysql-server

To list New MySql
yum list installed | grep -i mysql
start MySql server

/etc/init.d/mysqld start ## use restart after update
OR
service mysqld start ## use restart after update

chkconfig --levels 235 mysqld on

Last
mysql_upgrade -u root -p
Now my MySql version is 5.5.32

update MySQL version from 5.1 to 5.5 in CentOS 6.2

Centos 使用YUM安装MariaDB

1、在 /etc/yum.repos.d/ 下建立 MariaDB.repo
$ cd /etc/yum.repos.d
$ vim /etc/yum.repos.d/MariaDB.repo

添加如下配置：

# MariaDB 10.0 CentOS repository list - created 2013-08-23 13:08 UTC
# http://mariadb.org/mariadb/repositories/
[mariadb]
name = MariaDB
baseurl = http://yum.mariadb.org/10.0/centos6-amd64
gpgkey=https://yum.mariadb.org/RPM-GPG-KEY-MariaDB
gpgcheck=1

如果是其他的操作系统，可以在这里找到相关信息。

2、使用YUM安装MariaDB
$ sudo yum -y install MariaDB-client MariaDB-server MariaDB-devel

3、启动数据库
$ sudo service mysql start

4、修改Root的密码

$ mysqladmin -u root password ‘passwd’

5、配置远程访问，MariaDB为了安全起见，默认情况下绑定ip（ 127.0.0.1）。

$ mysql -u root -p
Enter password:
Welcome to the MariaDB monitor. Commands end with ; or \g.
Your MariaDB connection id is 4
Server version: 10.0.4-MariaDB MariaDB Server

Type ‘help;‘ or ‘\h‘ for help. Type ‘\c‘ to clear the current input statement.

MariaDB [(none)]>GRANT ALL PRIVILEGES ON *.* TO ‘root‘@‘%‘ IDENTIFIED BY ‘passwd’ WITH GRANT OPTION;

MariaDB [(none)]> flush privileges;

第一句中"%"表示任何主机都可以远程登录到该服务器上访问。如果要限制只有某台机器可以访问，将其换成相应的IP即可，如：

GRANT ALL PRIVILEGES ON *.* TO root@"172.168.193.25" IDENTIFIED BY "root";

第二句表示从mysql数据库的grant表中重新加载权限数据。因为MySQL把权限都放在了cache中，所以在做完更改后需要重新加载。

6、防火墙配置

如果系统的防火墙开着(or behind a hardware firewall or NAT)你必须放开mysql使用的TCP端口，通常都是3306。

7、大小写敏感

用root帐号登录后，在/etc/my.cnf 中的[mysqld]后添加添加lower_case_table_names=1，重启MYSQL服务，这时已设置成功：不区分表名的大小写;
lower_case_table_names参数详解：
lower_case_table_names = 0
其中 0：区分大小写，1：不区分大小写

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

ERROR 1045 (28000): Access denied for user ‘ithomer‘@‘localhost‘ (using password: YES)

/etc/init.d/mysqld stop
