centOs下的php+mysql+apache+ftp配置
在安装服务器时做了相应的笔记，这个方法是亲身经验成功的，随着版本的不断更新，也许会有一些地方不同，但是基本原理都是一样的。
1.安装CentOS 6 ,可以选择最小安装，也可以安装桌面
2.升级系统
yum update
3.安装mysql,并设置mysql开机自启动，同时启动mysql
yum install mysql
yum install mysql-server
chkconfig --levels 35 mysqld on
service mysqld start
4.配置mysql的root密码
mysql>; USE mysql;
mysql>; UPDATE user SET Password=PASSWORD('newpassword') WHERE user='root';
mysql>; FLUSH PRIVILEGES;
设置mysql密码还可以用：mysql_secure_installation 命令
mysql_secure_installation
Enter current password for root (enter for none): ( 回车)
OK, successfully used password, moving on...
Setting the root password ensures that nobody can log into the MySQL
root user without the proper authorisation.
Set root password? [Y/n] (Y)
New password: (123456)
Re-enter new password: (123456)
Password updated successfully!
Reloading privilege tables..
... Success!
By default, a MySQL installation has an anonymous user, allowing anyone
to log into MySQL 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]
(是否移出数据库的默认帐户，如果移出，那么在终端中直接输入mysql是会提示连接错误的)Y
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]
(是否禁止root的远程登录)Y
By default, MySQL 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
Reload privilege tables now? [Y/n] Y
**后来设置是否允许远程登录
mysql -u root -p
Enter Password: <your new password>
mysql>GRANT ALL PRIVILEGES ON *.* TO '用户名'@'%' IDENTIFIED BY '密码' WITH GRANT OPTION;
完成后就能用mysql-front远程管理mysql了。
设为开机启动
chkconfig mysqld on
5.安装apache,并设置开机启动
yum install httpd
chkconfig --levels 35 httpd on
service httpd start
这时候可以测试apache是否正常工作
直接浏览器访问localhost应该没问题，但是如果别的机子访问不了的话，是因为防火墙的关系，配置防火墙
（后面的ssl还会有这个问题的）
6.安装php
如果安装php53以下的版本的话，可能会导致项目放在这个环境中不能运行的情况，当时装的是php5.2结果发
现项目根本运行不起来，找了好久的原因才发现是php版本太低了（在这之前一直是以为json的原因，因为
php5.2没有json扩展），所以在安装前一定要看好版本在安装，否则以后项目出现问题不好找出原因。
yum install php53
yum install php53-mysql php53-gd php53-imap php53-ldap php53-odbc php53-pear php53-xml php53-
xmlrpc
这个时候php就安装完成拉，写个脚本测试一下
vi /var/www/html/info.php
输入
<?php
phpinfo();?>
访问localhost/info.php即可～
7.安装phpMyAdmin
首先先给系统安装epel 和rpmfushion两个软件大仓库
rpm -Uvh http://download.fedoraproject.org/pub/epel/6/i386/epel-release-6-5.noarch.rpm
rpm -Uvh http://download1.rpmfusion.org/free/el/updates/testing/6/i386/rpmfusion-free-release-
6-0.1.noarch.rpm http://download1.rpmfusion.org/nonfree/el/updates/testing/6/i386/rpmfusion-
nonfree-release-6-0.1.noarch.rpm
如果是centos 5 的话执行下面
rpm -Uvh http://download.fedora.redhat.com/pub/epel/5/i386/epel-release-5-4.noarch.rpm
rpm -Uvh http://download1.rpmfusion.org/free/el/updates/testing/5/i386/rpmfusion-free-release-
5-0.1.noarch.rpm http://download1.rpmfusion.org/nonfree/el/updates/testing/5/i386/rpmfusion-
nonfree-release-5-0.1.noarch.rpm
接着安装起来就很方便拉，～根本不需要去下载就可以获得最新的版本
yum install phpmyadmin
安装完成后还需要配置一下访问权限，使得出了本机外，其他机子也能访问phpMyAdmin
vi /etc/httpd/conf.d/phpMyAdmin.conf
找到两个directory的权限设置，Allow from 改成All
<Directory /usr/share/phpMyAdmin/>
Order Deny,Allow
Deny from All
Allow from 127.0.0.1
Allow from All
</Directory>
<Directory /usr/share/phpMyAdmin/setup/>
Order Deny,Allow
Deny from All
Allow from 127.0.0.1
Allow from All
</Directory>
重启服务器
service httpd restart
测试localhost/phpMyAdmin
用户名密码:root 123456
OK～ LAMP搭建完毕,
8.搭建SSL,让apache支持https
yum install mod_ssl
其实安装完这个模块后，重启完apache 就可以用https://localhost测试了，因为他创建了默认的证书
在/etc/pki/tls下
当然我们也可以用openssl创建自己的证书
yum install openssl
生成证书文件
创建一个rsa私钥,文件名为server.key
openssl genrsa -out server.key 1024
Generating RSA private key, 1024 bit long modulus
............++++++
............++++++
e is 65537 (0x10001)
用 server.key 生成证书签署请求 CSR
openssl req -new -key server.key -out server.csr
Country Name:两个字母的国家代号
State or Province Name:省份名称
Locality Name:城市名称
Organization Name:公司名称
Organizational Unit Name:部门名称
Common Name:你的姓名
Email Address:地址
至于 'extra' attributes 不用输入.直接回车
生成证书CRT文件server.crt。
openssl x509 -days 365 -req -in server.csr -signkey server.key -out server.crt
修改ssl.conf指定我们自己生成的证书
vi /etc/httpd/conf.d/ssl.conf
找到如下位置，修改路径
# Server Certificate:
# Point SSLCertificateFile at a PEM encoded certificate. If
# the certificate is encrypted, then you will be prompted for a
# pass phrase. Note that a kill -HUP will prompt again. A new
# certificate can be generated using the genkey(1) command.
SSLCertificateFile /etc/pki/tls/certs/localhost.crt
# Server Private Key:
# If the key is not combined with the certificate, use this
# directive to point at the key file. Keep in mind that if
# you've both a RSA and a DSA private key you can configure
# both in parallel (to also allow the use of DSA ciphers, etc.)
SSLCertificateKeyFile /etc/pki/tls/private/localhost.key
OK
service httpd restart
yum install vsftpd
2.启动/重启/关闭vsftpd服务器
/sbin/service vsftpd restart
Shutting down vsftpd: [ OK ]
Starting vsftpd for vsftpd: [ OK ]
OK表示重启成功了.
启动和关闭分别把restart改为start/stop即可.
如果是源码安装的,到安装文件夹下找到start.sh和shutdown.sh文件,执行它们就可以了.
根据下面修改
vi /etc/vsftpd/vsftpd.conf
# Allow anonymous FTP? (Beware - allowed by default if you comment this out).
anonymous_enable=NO
# if your users expect that (022 is used by most other ftpd's)
local_umask=022
local_root=/
vi /etc/vsftpd/ftpusers
# Users that are not allowed to login via ftp
#root
vi /etc/vsftpd/user_list
# for users that are denied.
#root
防火墙配置
a.添加.允许访问端口{80: http}.
-A 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
