Linux下Apache+Mysql+PHP的安装与配置
（1）Apache的安装与配置 思路：首先在官网下载APACHE源码，本系统下载版本为httpd-2.2.17.tar.gz，下面几步为在终端的配置命令 tar zxvf httpd-2.2.17.tar.gz cd httpd-2.2.17 ./configure --prefix=/usr/local/apache make make install service httpd sta
（1） Apache的安装与配置
思路：首先在官网下载APACHE源码，本系统下载版本为httpd-2.2.17.tar.gz，下面几步为在终端的配置命令
tar zxvf httpd-2.2.17.tar.gz
cd httpd-2.2.17
./configure --prefix=/usr/local/apache
make
make install
service httpd start
如果出现：
|
Starting httpd: httpd: Could not reliably determine the server's fully qualified domain name, using 222.31.76.227 for ServerName [ OK ] |
说明安装成功！
如果希望apache开机自启动的话，可以通过以下命令在/etc/rc.d/rc.local加入自启动命令：
echo "service httpd start">>/etc/rc.d/rc.local
测试Apache
在/var/www/html目录下建立index.html文件
|
Welcome to Apache!! |
保存后，在浏览器上输入http://XXX.XXX.XXX.XXX（Web服务器的IP）查看结果
注意：iptables必须关闭或者将80端口加到iptables中
（2） Mysql-client的安装与配置
思路：由于MYSQL没有源码包可以下载，所以本系统使用MYSQL的二进制安装包，使用版本为mysql-5.5.10-linux2.6-x86_64.tar.gz，下面几步为在终端的配置命令（可直接粘贴）
tar zxvf mysql-5.5.10-linux2.6-x86_64.tar.gz
cd /usr/local
ln -s /home/software/mysql-5.5.10-linux2.6-x86_64 mysql
cd mysql/
vi INSTALL-BINARY
看到以下部分为安装步骤
|
To install and use a MySQL binary distribution, the basic command sequence looks like this: shell> groupadd mysql shell> useradd -r -g mysql mysql shell> cd /usr/local shell> tar zxvf /path/to/mysql-VERSION-OS.tar.gz shell> ln -s full-path-to-mysql-VERSION-OS mysql shell> cd mysql shell> chown -R mysql . shell> chgrp -R mysql . shell> scripts/mysql_install_db --user=mysql shell> chown -R root . shell> chown -R mysql data # Next command is optional shell> cp support-files/my-medium.cnf /etc/my.cnf shell> bin/mysqld_safe --user=mysql & # Next command is optional shell> cp support-files/mysql.server /etc/init.d/mysql.server //开机自启动(后面还需几步)
|
如果已经安装在安装操作系统时已经安装过MYSQL，那么前6步（高亮部分）目前已经完成
（需要注意的是 data目录下存放的就是一个又一个数据库，所以，必须将权限设置为mysql，否则，mysql本身进不去，配置就会失败）
chown -R mysql.mysql .
scripts/mysql_install_db --user=mysql --datadir=/usr/local/mysql/data/
chown -R root .
chown -R mysql data
cp support-files/my-medium.cnf /etc/my.cnf
bin/mysqld_safe --user=mysql &
service mysqld start
若显示：
Starting MySQL.. [ OK ]
则说明mysql已成功启用！
使用 mysql_install_db --user=mysql 创建新的MySQL授权表，使用者为mysql
使用 mysqld_safe --user=mysql & 以用户名user_name或数字用户ID user_id运行mysqld服务器。(本文中的“用户”指系统登录账户，而不是 授权表中的MySQL用户)
让MYSQL自启动
cp support-files/mysql.server /etc/init.d/mysqld
chmod 700 /etc/init.d/mysqld
chkconfig --add mysqld
如果遇到以下问题：
启动MYSQL出错，提示：
Starting mysqld daemon with databases from /usr/local/mysql/data
STOPPING server from pid file /usr/local/mysql/data/xmcncn.pid
061103 15:25:32 mysqld ended
解决方法：
vi /etc/my.cnf
看看[mysqld]下有没有
port = 3306
添加上就可以了
touch /tmp/mysql.sock
killall -9 mysqld
/usr/local/mysql/bin/mysqld_safe -user=mysql &
成功启动
（3）php的安装与配置
首先，安装php前，以下包可能会需要安装：zlib-1.2.3.tar.gz、libpng-1.2.24.tar.gz、freetype-2.3.11.tar.gz、libtool-2.4.tar.gz、jpegsrc.v6b.tar.gz、autoconf-2.61.tar.gz、gd-2.0.35.tar.gz、libxml2-2.7.3.tar.gz
在官网下载php源码，本系统下载版本为php-5.3.6.tar，下面几步为在终端的配置命令（可直接粘贴）
cd /home/software/
tar -xvf php-5.3.6.tar
cd php-5.3.6
./configure --prefix=/usr/local/php --with-apxs2=/usr/local/apache/bin/apxs --with-mysql=/usr/local/mysql --with-openssl-dir=/usr/lib/openssl --with-openssl
配置后若如下显示License，则说明成功，否侧可能还缺少上述的包。

Thank you for using PHP. |
make
make test //可以不做
make install
cp php.ini-development /etc/php.ini
vi /usr/local/apache/conf/httpd.conf
加入一句话：
|
AddType application/x-httpd-php .php |
cd /var/www/html
vi index.php
新建php测试代码为：
|
phpinfo(); ?> |
重启apache，重启前要先修改/etc/selinux/config，将SELINUX=enforcing 改成SELINUX=disabled：
vi /etc/selinux/config
|
# This file controls the state of SELinux on the system. # SELINUX= can take one of these three values: # enforcing - SELinux security policy is enforced. # permissive - SELinux prints warnings instead of enforcing. # disabled - SELinux is fully disabled. SELINUX=disabled # SELINUXTYPE= type of policy in use. Possible values are: # targeted - Only targeted network daemons are protected. # strict - Full SELinux protection. SELINUXTYPE=targeted |
service httpd restart
出现以下语句说明重启成功：
|
Stopping httpd: [ OK ] Starting httpd: httpd: Could not reliably determine the server's fully qualified domain name, using 222.31.76.227 for ServerName [ OK ] |
在浏览器输入http://XXX.XXX.XXX.XXX/index.php，若显示phpinfo信息说明php配置成功。
若能显示phpinfo信息，但发现无法连接数据库(没有MYSQL的信息)，说明php与mysql相连的模块包没有安装成功，可尝试下载安装php-mysql的rpm包(php-mysql-5.1.6-27.el5.x86_64.rpm)，安装它还需先安装php-pdo的rpm包(php-pdo-5.1.6-27.el5.x86_64.rpm)，pdo就是专门用于连接php和mysql的。
在以后的web端配置安装时，若phpinfo的基本信息能正常显示，但缺少某个模块功能，可单独下载其对应的rpm包，安装即可。
在/var/www/html下新建一个test.php，用于测试连接远程数据库：
|
echo "Hello World!"; $db=mysql_connect("远程服务器IP","用户名","password") or die ("mysql connected failed! "); mysql_select_db("数据库名",$db); $sql="select * from users"; $result=mysql_fetch_row(mysql_query($sql)); print_r($result); ?> |
