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

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/$basearch/ gpgcheck=1 gpgkey=http://mirrors.sohu.com/centos/RPM-GPG-KEY-CentOS-5 #released updates [updates] name=CentOS-$releasever - Updates baseurl=http://mirrors.sohu.com/centos/$releasever/updates/$basearch/ gpgcheck=1 gpgkey=http://mirrors.sohu.com/centos/RPM-GPG-KEY-CentOS-5 #packages used/produced in the build but not released [addons] name=CentOS-$releasever - Addons baseurl=http://mirrors.sohu.com/centos/$releasever/addons/$basearch/ gpgcheck=1 gpgkey=http://mirrors.sohu.com/centos/RPM-GPG-KEY-CentOS-5 #additional packages that may be useful [extras] name=CentOS-$releasever - Extras baseurl=http://mirrors.sohu.com/centos/$releasever/extras/$basearch/ gpgcheck=1 gpgkey=http://mirrors.sohu.com/centos/RPM-GPG-KEY-CentOS-5 #additional packages that extend functionality of existing packages [centosplus] name=CentOS-$releasever - Plus baseurl=http://mirrors.sohu.com/centos/$releasever/centosplus/$basearch/ 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

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 PHP 5.5.9 (cli) (built: Feb 18 2014 14:51:49) Copyright (c) 1997-2014 The PHP Group Zend Engine v2.5.0, Copyright (c) 1998-2014 Zend Technologies with Zend OPcache v7.0.3, Copyright (c) 1999-2014, by Zend Technologies

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 Ref: http://www.webtatic.com/packages/mysql55/ http://www.if-not-true-then-false.com/2010/install-mysql-on-fedora-centos-red-hat-rhel/ 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 mysqld_safe --skip-grant-tables & mysql -u root mysql> use mysql;

mysql> grant all privileges on *.* to "root"@"%" identified by "password" with grant option; flush privileges; # 添加用户

mysql> grant Select on your_dbname.* to "username"@"%" identified by "password" with grant option; flush privileges; # 赋值只读权限（Select） mysql> update user set password=PASSWORD("newrootpassword") where User='root'; flush privileges; # 修改密码 mysql> quit /etc/init.d/mysqld restart /etc/init.d/mysqld stop /etc/init.d/mysqld start
