操作系统是CENTOS 6.5
yum中最新的也是Python 2.6.6，只能下载Python 2.7.9的源代码自己编译安装。
操作步骤如下：
1）安装devtoolset
yum groupinstall "Development tools"
2）安装编译Python需要的包包
yum install zlib-devel
yum install bzip2-devel
yum install openssl-devel
yum install ncurses-devel
yum install sqlite-devel
安装Python2.7
用root登陆之后使用命令
wget https://www.python.org/ftp/python/2.7.10/Python-2.7.10.tgz
使用解压命令tar解压刚刚下载的文件
tar xf Python-2.7.10.tgz
进入解压之后的文件
cd Python-2.7.10.tgz
运行检查目录结构
./configure --prefix=/usr/local
编译
make && make install
安装成功之后，你可以在 /usr/local/bin/python2.7
找到 Python 2.7
将python命令指向Python 2.7.9
ln -s /usr/local/bin/python2.7 /usr/local/bin/python
检查Python版本
sh
sh-4.1# python -V
Python 2.7.9
安装PIP
To install pip, securely download
wget https://bootstrap.pypa.io/get-pip.py
Then run the following (which may require administrator access):
python get-pip.py
使用VIM编辑
vim开始使用
：wq保存退出
yum命令不兼容python2.7，需修改/usr/bin/yum文件，将第一行由“#!/usr/bin/python”改为“#!/usr/bin/python2.6"
安装Mysql
1.使用yum命令安装mysql
yum -y install mysql-server
2.设置开机启动
chkconfig mysqld on
3.启动MySQL服务
service mysqld start
4.设置MySQL的root用户设置密码
mysql -u root
mysql> select user,host,password from mysql.user;
+------+-----------+----------+
| user | host | password |
+------+-----------+----------+
| root | localhost | |
| root | bogon | |
| root | 127.0.0.1 | |
| | localhost | |
| | bogon | |
+------+-----------+----------+
5 rows in set (0.01 sec)
查询用户的密码，都为空，用下面的命令设置root的密码为root
mysql> set password for root@localhost=password('root');
mysql> exit
5.用新密码登陆
mysql -u root -p
Enter password:
6.创建mysql新用户test_user
mysql> create user 'test_user'@'%' identified by 'test_user';
Query OK, 0 rows affected (0.00 sec)
7.给新用户test_user授权，让他可以从外部登陆和本地登陆注意：@左边是用户名，右边是域名、IP和%，表示可以访问mysql的域名和IP，%表示外部任何地址都能访问。
mysql> grant all privileges on . to 'test_user'@'localhost' identified by 'test_user';
Query OK, 0 rows affected (0.00 sec)
mysql> grant all privileges on . to 'test_user'@'%' identified by 'test_user';
Query OK, 0 rows affected (0.00 sec)
mysql> select user,host,password from mysql.user;
+----------+-----------+-------------------------------------------+
| user | host | password |
+----------+-----------+-------------------------------------------+
| root | localhost | *81F5E21E35407D884A6CD4A731AEBFB6AF209E1B |
| root | bogon | |
| root | 127.0.0.1 | |
| | localhost | |
| | bogon | |
| test_user | % | *3046CF87132BBD4FDDF06F321C6859074843B7D3 |
| test_user | localhost | *3046CF87132BBD4FDDF06F321C6859074843B7D3 |
+----------+-----------+-------------------------------------------+
7 rows in set (0.00 sec)
mysql> flush privileges;
Query OK, 0 rows affected (0.01 sec)
8.查看mysql5.1的默认存储引擎从下面的执行结果可以看出，mysql的默认引擎是MyISAM，这个引擎是不支持事务的。
mysql> show engines;
+------------+---------+------------------------------------------------------------+--------------+------+------------+
| Engine | Support | Comment | Transactions | XA | Savepoints |
+------------+---------+------------------------------------------------------------+--------------+------+------------+
| MRG_MYISAM | YES | Collection of identical MyISAM tables | NO | NO | NO |
| CSV | YES | CSV storage engine | NO | NO | NO |
| MyISAM | DEFAULT | Default engine as of MySQL 3.23 with great performance | NO | NO | NO |
| InnoDB | YES | Supports transactions, row-level locking, and foreign keys | YES | YES | YES |
| MEMORY | YES | Hash based, stored in memory, useful for temporary tables | NO | NO | NO |
+------------+---------+------------------------------------------------------------+--------------+------+------------+
5 rows in set (0.00 sec)
也可以以下面的方式查看
mysql> show variables like 'storage_engine';
+----------------+--------+
| Variable_name | Value |
+----------------+--------+
| storage_engine | MyISAM |
+----------------+--------+
1 row in set (0.00 sec)
9.修改mysql的默认引擎为InnoDB
9.1 停止mysql
mysql> exit;
service mysqld stop
9.2 修改/etc/my.cnf
[mysqld] 后加入
default-storage-engine=InnoDB
加入后my.cnf的内容为：
more my.cnf
[mysqld]
datadir=/var/lib/mysql
socket=/var/lib/mysql/mysql.sock
user=mysql
default-storage-engine=InnoDB
[mysqld_safe]
log-error=/var/log/mysqld.log
pid-file=/var/run/mysqld/mysqld.pid
9.3 启动mysql
service mysqld start
Starting mysqld: [ OK ]
9.4 查看mysql默认存储引擎
mysql> show variables like 'storage_engine';
10.CentOS6.5开放mysql端口3306CentOS6.5默认是不开放端口的，如果要让外部的系统访问CentOS6.5上的mysql，必须开放mysql的端口330610.1 修改/etc/sysconfig/iptables添加下面一行
-A INPUT -m state --state NEW -m tcp -p tcp --dport 3306 -j ACCEPT
修改后iptables中的内容是
more /etc/sysconfig/iptables
11.重启防火墙
service iptables restart
这样就可以从外部访问mysql了。
至此，mysql在CentOS6.5上的安装过程、用户创建、外部访问的步骤全部完成。
安装nginx
1、安装prce(重定向支持)和openssl(https支持，如果不需要https可以不安装。)
yum -y install pcre*
yum -y install openssl*
CentOS 6.5 我安装的时候是选择的“基本服务器”，默认这两个包都没安装全，所以这两个都运行安装即可。
2、下载nginx 1.8.0
3、解压编译安装
tar -zxvf nginx-1.8.0.tar.gz
然后进入目录编译安装
cd nginx-1.8.0
./configure --prefix=/usr/local/nginx-1.8.0 --with-http_ssl_module --with-http_spdy_module --with-http_stub_status_module --with-pcre
如果没有error信息，就可以执行下边的安装了：
make
make install
4、开启nginx进程
/usr/local/nginx-1.8.0/sbin/nginx
重启或关闭进程：
/usr/local/nginx-1.8.0/sbin/nginx -s reload
/usr/local/nginx-1.8.0/sbin/nginx -s stop
5、关闭防火墙，或者添加防火墙规则就可以测试了。
service iptables stop
或者编辑配置文件：
vi /etc/sysconfig/iptables
添加这样一条开放80端口的规则后保存：
-A INPUT -m state --state NEW -m tcp -p tcp --dport 80 -j ACCEPT
重启服务即可:
service iptables restart
ok，，可以浏览器访问了。Welcome to nginx!
6、配置nginx.conf
vim /usr/local/nginx-1.8.0/conf/nginx.conf
运行用户去掉注释
user www-data;
安装MYSQL-python
首先安装 setuptools，下载源代码包：
wget http://pypi.python.org/packages/source/s/setuptools/setuptools-0.6c11.tar.gz
tar -xzvf setuptools-0.6c11.tar.gz
python setup.py build
python setup.py install
然后安装一些扩展库
yum -y install rpm-build gcc-c++ mysql-devel python-devel
最后安装MySQL-python 下载源代码包：
wget http://download.sourceforge.net/sourceforge/mysql-python/MySQL-python-1.2.3.tar.gz
tar -zxvf MySQL-python-1.2.3.tar.gz
编辑 site.cfg
把 mysql_config 那一行取消注释，并改为：
mysql_config = /usr/lib64/mysql/mysql_config （根据自己mysql安装位置定义）
python setup.py build
python setup.py install
