阿里云 centos 环境配置与 django 部署

1. 免密码登陆

# 本机生成密钥, 并将 pub 复制到阿里云服务器上
$ ssh-keygen -t rsa -P ''  # -P表示密码，-P '' 就表示空密码
$ scp ~/.ssh/FILENAME.pub root@server_ip:/root

# 阿里云服务器上将 pub 放入 authorized_keys 中
# cat FILENAME.pub >> ~/.ssh/authorized_keys
# chmod 600 ~/.ssh/authorized_keys

2. yum

默认的环境并不 OK.

1) 运行出错提示    No module named yum

解决方案: #vi /usr/bin/yum 将 #!/usr/bin/python 修改为  #!/usr/bin/python2.4

2) 下载yum的配置源

mkdir /etc/yum.repos.d/
cd /etc/yum.repos.d/
wget http://docs.linuxtone.org/soft/lemp/CentOS-Base.repo

3) 运行yum makecache生成缓存

若重新安装 yum

查看yum包  rpm -qa|grep yum 

卸载  rpm -qa|grep yum|xargs rpm -e --nodeps 

安装:

1) 下载安装所需的三个文件, 下载地址: http://centos.ustc.edu.cn/centos/5/os/x86_64/CentOS/

yum-3.2.22-40.el5.centos.noarch.rpm
yum-fastestmirror-1.1.16-21.el5.centos.noarch.rpm
yum-metadata-parser-1.1.2-4.el5.x86_64.rpm

2)  安装命令

rpm -ivh yum-*

注意：yum和yum-fastestmirror相互依赖，所以需要同时安装。

3) 恢复 /etc/yum.conf 文件, 一般卸载时会自动备份.

3. 开发环境依赖包更新

$ yum update
$ yum -y install gcc g++ autoconf
$ yum -y install openssl openssl-devel zlib zlib-devel

4. python

手动编译安装 Python, 官网下载源码即可.

./configure  --enable-shared  # if not, error -- libpython2.7.a:  could not read symbols: Bad value
make
make install

此时运行 python 可能报错: 

python: error while loading shared  libraries: libpython2.7.so.1.0:

  cannot open shared object file: No such file or

 解决方案:

$ vim /etc/ld.so.conf.d/python2.7.conf
# 加入内容：
/usr/local/lib

#保存退出后运行：
$ ldconfig

pip 与 库. 源码 setup.py 安装 setuptools 与 pip

yum install -y  python-setuptools python-devel
sudo easy_install -U distribute

5. 手动安装 git

http://distfiles.macports.org/git/ 下载最新 git

$ yum install gettext-devel

$ wget http://distfiles.macports.org/git/git-2.1.1.tar.gz
$ tar zxvf git-2.1.1.tar.gz
$ cd git-2.1.1
$ autoconf 
$ ./configure
$ make 
$ make install

6. MySQL

# rpm -Uvh http://repo.webtatic.com/yum/centos/5/latest.rpm  # 导入第三方源webtatic
# yum remove mysql mysql-*
# yum install libmysqlclient15 --enablerepo=webtatic
# yum install mysql55 mysql55-server --enablerepo=webtatic
# service mysqld start

安全性配置

# mysql_secure_installation  # secure settings

 字符编码设置:

http://www.cnblogs.com/misspy/p/4033352.html

开机自动启动

# chkconfig --levels 235 mysqld on
# service mysqld restart

7. apache2 与 mod_wsgi

# yum install httpd httpd-devel

# chkconfig --levels 235 httpd on
# service httpd restart

源码安装 mod_wsgi https://github.com/GrahamDumpleton/mod_wsgi
