64位CentOS 5.5手动安装lamp，要求curl、json、pdo_mysql、gd，记录如下。
centos 5.4、5.5、5.6的内核都是2.6.18，都可以安装php 5.3。
卸载旧版本apache、php、mysql：sudo yum erase httpd sudo yum erase php php-cli sudo yum erase mysql 下载编译安装apache 2.2.19： cd ~ wget tar -jxvf httpd-2.2.19.tar.bz2 cd httpd-2.2.19 sudo yum install gcc ./configure --prefix=/opt/httpd --enable-so --enable-rewrite make sudo make install sudo /opt/httpd/bin/httpd -k start安装完apache，用浏览器访问，能正常显示说明装好了。
下载安装mysql 5.5.13：下载这2个（64位的）： MySQL-client MySQL-server
sudo yum install libaio sudo rpm -i MySQL-client-5.5.13-1.rhel5.x86_64.rpm sudo rpm -i MySQL-server-5.5.13-1.rhel5.x86_64.rpm sudo /etc/init.d/mysql start /usr/bin/mysqladmin -u root password '1' sudo cp /usr/share/mysql/my-medium.cnf /etc/my.cnf sudo /etc/init.d/mysql restart mysql -uroot -p1 下载编译安装php 5.3.6： sudo yum install libxml2 libxml2-devel curl curl-devel libjpeg libjpeg-devel libpng libpng-devel libmcrypt libmcrypt-devel tar -jxvf php-5.3.6.tar.bz2 cd php-5.3.6 ./configure --prefix=/opt/php -with-apxs2=/opt/httpd/bin/apxs --with-curl --with-mcrypt --enable-mbstring --with-iconv --with-gd -with-jpeg-dir=/usr/local/lib --enable-pdo --with-pdo-mysql=mysqlnd --with-mysqli=mysqlnd make sudo make install sudo cp php.ini-development /opt/php/lib/php.ini sudo ln -s /opt/php/bin/php /usr/bin/php sudo vi /opt/php/lib/php.ini 把include_path前面的分号删除，改成include_path = "/opt/php/lib/php" sudo vi /opt/httpd/conf/httpd.conf 在最下面加入一行AddHandler application/x-httpd-php .php sudo /opt/httpd/bin/httpd -k restart sudo vi /opt/httpd/htdocs/phpinfo.phpphpinfo.php的内容如下：
<?php phpinfo(); ?>安装完php，重启apache，用浏览器访问，能正常显示说明php装好了。搜索mysqlnd、pdo_mysql、mysqli，如果有，则说明php能访问mysql。
把apache加入系统service，开机自启动sudo cp /opt/httpd/bin/apachectl /etc/init.d/httpd sudo vi /etc/init.d/httpd 在文件开头加入下面几行： #!/bin/sh # chkconfig: 2345 85 15 # description: Apache is a World Wide Web server. sudo chmod +x /etc/init.d/httpd sudo /sbin/chkconfig --add httpd sudo /sbin/chkconfig --list httpd sudo ln -s /sbin/chkconfig /usr/bin/chkconfig sudo ln -s /sbin/service /usr/bin/service 把mysql加入系统service，开机自启动sudo /sbin/chkconfig --list mysql通过rpm安装的mysql，已经开机自启动了。
安装php扩展ssh2先安装libssh2
./configure
make
sudo make install
再安装ssh2
/opt/php/bin/phpize && ./configure --with-ssh2 && make
sudo make install
在/opt/php/lib/php.ini中加1行：
extension=ssh2.so
centos 5.4升级到5.6： 先修改更新源为国内的更新源cd /etc/yum.repos.d sudo mv CentOS-Base.repo CentOS-Base.repo.save sudo wget 清理残留文件然后更新标准库，再升级sudo yum clean all sudo yum update glibc\* sudo yum update yum\* rpm\* Python\* sudo yum clean all sudo yum update sudo reboot Linux 设置服务器时区 UTC 0区Linux服务器使用UTC 0区Atlantic/Reykjavik，这样各个程序都比较简单，时间不用算来算去的。
sudo tzselect 6) Atlantic Ocean 6 5) Iceland 5 You can make this change permanent for yourself by appending the line TZ='Atlantic/Reykjavik'; export TZ to the file '.profile' in your home directory; then log out and log in again. Here is that TZ value again, this time on standard output so that you can use the /usr/bin/tzselect command in shell scripts: Atlantic/Reykjavik
