centOs下的php+mysql+apache+ftp配置，centosapache_PHP教程

centOs下的php+mysql+apache+ftp配置，centosapache

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:
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

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

Order Deny,Allow
Deny from All
Allow from 127.0.0.1
Allow from All


Order Deny,Allow
Deny from All
Allow from 127.0.0.1
Allow from All

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
