在 RedHat 6.5 上安装OET¶
注意：如没有特殊说明，本文档中所有命令都是通过 root 用户来执行的
系统的基本配置¶
配置本地Yum源¶
进入yum源配置文件所在的目录:
# cd /etc/yum.repos.d
创建备份文件夹，将不需要的配置文件移动到备份文件夹内:
# mkdir bak
# mv * bak
建立新的配置文件，配置好本地yum源:
# touch local-source.repo
向配置文件中添加如下内容并保存:
[local-source]
name=server
baseurl=file:///mnt
enabled=1
gpgcheck=0
挂载光盘，并 mount 至 /mnt 路径下:
# mount -o ro /dev/cdrom /mnt
通过yum命令，测试是否配置成功:
# yum clean all
# yum list mysql*
如果看到类似下面的输出，则说明配置成功:
.........

关闭防火墙与selinux¶
临时关闭防火墙服务:
# service iptables stop
防止防火墙开机自启:
# chkconfig iptables off
# chkconfig --list iptables
iptables 0:off 1:off 2:off 3:off 4:off 5:off 6:off
临时关闭selinux:
# getenforce
Enforcing
# setenforce 0
# getenforce
Permissive
防止selinux开机自启:
# grep '^SELINUX=' /etc/selinux/config
SELINUX=enforcing
# sed -i 's/^SELINUX=enforcing/SELINUX=disabled/' /etc/selinux/config
# grep '^SELINUX=' /etc/selinux/config
SELINUX=disabled
安装并配置MySQL¶
使用yum快速安装MySQL:
# yum install mysql mysql-server mysql-devel -y
初始化并启动MySQL:
# service mysqld start
为MySQL的超级用户 root 设置密码，本例中密码为123456，读者可以自行修改:
# mysqladmin -u root password 123456
使用root用户登录MySQL，如果成功登录，说明配置成功:
# mysql -uroot -p123456 -s
mysql>
使用yum快速安装所需的包¶
上传并解压 oet 包¶
建立路径，用以存放程序相关文件，本文档中以 /software 为例:
# mkdir /software
使用SSH或FTP工具，将文件上传到 /software 路径中，并解压释放相关文件:
# cd /software
# tar -xf oet-1.0.0-el6.tar
将解压后的 oet 文件夹放入要安装的路径中，本文档中以 /oet 为例。 然后进入 /oet 路径中，查看路径下的内容:
# mv oet /
# cd /oet
# ls
collected common data docs etc manage.py oet perfmon setup util
安装Redis¶
进入相关路径下，执行安装脚本，输入服务器发行版本，安装其rpm包:
# cd /oet/setup/redis
# ./install.sh
==== input your system version ====
if it's RedHat 5, then input 5
if it's RedHat 6, then input 6
if it's RedHat 7, then input 7

your choice is 6
==== installing rpms ====
...........
...........

rpms install success
修改Redis的配置文件，查找到databases配置项，将16改为1600，确保数据库号码足够使用:
# vim /etc/redis.conf
databases 1600
开启redis服务，并登陆验证安装是否成功:
# service redis start
Starting redis-server: [ OK ]
# redis-cli
redis 127.0.0.1:6379>
安装Nginx¶
进入相关路径下，执行安装脚本，输入服务器发行版本，安装其rpm包:
# cd /oet/setup/nginx
# ./install.sh
==== input your system version ====
if it's RedHat 5, then input 5
if it's RedHat 6, then input 6
if it's RedHat 7, then input 7

# service nginx start
Starting nginx: [ OK ]
# curl localhost 2>/dev/null|grep title
<title>Welcome to nginx!</title>

# cd /oet/setup/tick
# ./install.sh

安装OIC¶
OIC（Oracle Instant Client），是Oracle官方的精简版客户端，为了使产品可以正常连接用户的Oracle数据库，必须要安装这一工具。
进入相关路径下，执行安装脚本:
# cd /oet/setup/oic
# ./install.sh
==== installing oic rpms to system ====
find oic files,handing..
...............
...............
Installed:
oracle-instantclient11.2-basic.x86_64 0:11.2.0.4.0-1
oracle-instantclient11.2-devel.x86_64 0:11.2.0.4.0-1

basic oic files install success
==== echo environments to /root/.bash_profile ====
echo environments complete.
==== shell job done,please help as behind ====
Please execute the command:"source /root/.bash_profile",and test with "sqlplus" command.
按照提示运行相关命令，使root用户 bash_profile 文件中新添加的环境变量生效，并测试安装结果:
# source /root/.bash_profile
# sqlplus -v
SQL*Plus: Release 11.2.0.4.0 Production
如果您执行 sqlplus -v 时不能立即响应，则需要正确配置 /etc/hosts 文件中的主机名，保持hostname与hosts文件中127.0.0.1对应的名称一致即可，本例中主机名为 mini-server-a
# hostname
mini-server-a
# vim /etc/hosts
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
127.0.0.1 mini-server-a
# sqlplus -v
SQL*Plus: Release 11.2.0.4.0 Production
确保Python版本大于2.7.9（不支持Python3）¶
检查python版本¶
检查python当前的版本:
# python --version
Python 2.6.6
如果您的版本为 2.7.9, 2.7.10, 2.7.11等，且不是python3，可以跳过此步骤，直接安装相关组件
如果发现python版本低于2.7.9，则需要对pyhon进行升级。然而有些系统组件只依赖旧版本。因此，我们采用安装python版本管理器的方式，来管理多个版本的python。
安装pyenv¶
进入相关路径下，执行安装脚本:
# cd /oet/setup/pyenv
# ./install.sh
==== installing basic softwares with yum ====
.................
.................
Complete!
basic install success
==== copying basic files to /root/.pyenv ====
find files,handing..
basic files copy success
==== echo environments to /root/.bash_profile ====
echo environments complete.
==== shell job done,please help as behind ====
Please execute the command:"source /root/.bash_profile",and test with "pyenv" command.
按照提示运行相关命令，使root用户 bash_profile 文件中新添加的环境变量生效，并测试安装结果:
# source /root/.bash_profile
# pyenv -v
pyenv 20160509
使用pyenv安装python 2.7.9¶
您可以手动来操作这一步骤，来了解pyenv的简单用法。或者您也可以跳过这一步骤，直接进行到下一步骤：通过pip安装Python组件，在这一步骤中，如果您没有安装过2.7.9，安装脚本会自动帮您安装。
检查操作系统当前有哪些版本的python:
# pyenv versions
* system (set by /root/.pyenv/version)
通过安装2.7.9版本的python，这一步骤可能需要耐心等待几分钟:
# pyenv install 2.7.9
Installing Python-2.7.9...
patching file ./Lib/site.py
patching file ./Lib/ssl.py
Installed Python-2.7.9 to /root/.pyenv/versions/2.7.9
验证一下是否安装成功，可以看到，版本列表里多了2.7.9，不过系统的默认版本仍然是系统自带版本:
# pyenv versions
* system (set by /root/.pyenv/version)
2.7.9
# python --version
Python 2.6.6
通过pyenv，将系统默认的python版本改为2.7.9，并验证效果:
# pyenv global 2.7.9
# pyenv versions
system
* 2.7.9 (set by /root/.pyenv/version)
# python --version
Python 2.7.9
通过pip安装Python组件¶
进入相关路径下，执行安装脚本。注意，此步骤会做以下操作：
- 通过pyenv安装2.7.9版本的python。
- 将默认的python版本改为2.7.9。
- 建立名为 oet 的虚拟python环境，
- 将依赖的组件安装到此虚拟环境中。
在此过程中，由于编译安装python等步骤需要大量消耗CPU资源，可能会导致系统短暂卡顿几分钟，耐心等待即可。:
# cd /oet/setup/wheel/
# ./install.sh
=== make sure pyenv is installed ===
system (set by /root/.pyenv/version)
yes,we do have pyenv
=== make sure python 2.7.9 is installed ===
pyenv: version `2.7.9' not installed
no,we don't have python 2.7.9,try to install it.
Installing Python-2.7.9...
patching file ./Lib/site.py
patching file ./Lib/ssl.py
Installed Python-2.7.9 to /root/.pyenv/versions/2.7.9

可以看到，所有的包都是安装在了虚拟环境 oet 中，而全局的python 2.7.9的环境没有受到影响。
安装产品¶
安装并配置MySQL¶
在MySQL数据库中建立django数据库及相关用户，并删除匿名用户:
# mysql -uroot -p123456
mysql> create database oet character set utf8;
Query OK, 1 row affected (0.00 sec)
mysql> delete from mysql.user where user='';
Query OK, 2 rows affected (0.03 sec)
mysql> create user 'oet'@'%' identified by 'oet';
Query OK, 0 rows affected (0.02 sec)
mysql> grant all on *.* to oet;
Query OK, 0 rows affected (0.00 sec)
mysql> flush privileges;
Query OK, 0 rows affected (0.00 sec)
mysql> Bye
使用刚建立的用户，测试是否执行成功:
# mysql -uoet -poet oet
mysql>
配置并测试Django¶
进入相关目录并激活虚拟环境:
# cd /oet
# pyenv activate oet
在数据库中创建相关的表结构并导入数据:
# ./manage.py migrate

部署Django项目¶
进入相关目录，开启supervisor服务:
# cd /oet
# supervisord
注意，supervisor相关的命令，只有在产品根路径中（即/oet），才可以生效。
查看supervisor服务开启的状态:
# bash util/checkproc.sh
