从最干净的环境安装 ?
- vim
- tmux
- mysql
- nginx
- uwsgi
- pylibmc
源里有的并且版本较新的直接yum装就可以了.
yum里比较有用的指令包括
- yum install 软件名 安装软件
- yum search 名字 查询有关的软件信息
- yum info 名字 查寻软件源的相关信息
-
yum install vim?文本编辑器 -
yum install python-setuptools?python库安装工具 easy_install -
yum install mysql-server mysql?mysql -
yum install make gcc gcc-c++?编译软件时用到的安装工具 -
yum install wget?下载工具
基本软件安装完成,现在编一个最简单的软件练手.
安装 tmux
下载源码 http://tmux.sourceforge.net/
解压 tar -xvf tmux*.tar.gz
切换到tmux源码目录 cd tmux*
检测安装环境,生成make文件 ?./configure
最后一行报错:
configure: error: "libevent not found"
可以google一下这个错误也会有解决方法,不过感觉提示可以知道是libevent这个库没有安装
yum search可以查看这些库的相关信息
yum search libevent
Matched: libevent libevent-devel.i686 : Header files, libraries and development documentation for: libevent libevent.i686 : Abstract asynchronous event notification library
估计libevent-devel和libevent都有用,都装一下.
yum install libevent libevent-devel
再./configure
这次提示的是
configure: error: “curses not found”
同上yum search然后yum install
再./configure, 没有提示error了,并且提示生成了make文件.
make make install
练手完毕,开始安装web环境需要的软件.
编译安装nginx,源里的nginx是7.X的,但是8.0的nginx才支持uwsgi,所以要自己编译.
先看一下这个网页里有nginx的依赖库,直接yum装一下就好了
yum -y install gcc gcc-c++ glibc glibc-devel glib2 glib2-devel autoconf libmcrypt libmcrypt-devel mhash mhash-devel pcre pcre-devel libjpeg libjpeg-devel libpng libpng-devel freetype freetype-devel libxml2 libxml2-devel libidn libidn-devel zlib zlib-devel bzip2 bzip2-devel ncurses ncurses-devel curl curl-devel e2fsprogs e2fsprogs-devel krb5 krb5-devel openssl openssl-devel mysql mysql-server mysql-devel
基本上该装的库都装了, 然后去官网下载稳定版本的库的源码.
然后
./configure make make install
如果需要自己定制编译参数的话可以看下面的文章:
- 1
- 2
这两篇文章讲了nginx的编译参数,和如何把nginx添加到系统的服务里,使用service启动和停止的方法,值得注意的是如果使用了自定义编译参数,需要更改nginx启动文件的相应的路径.
我的编译参数如下:
nginx: configure arguments: –prefix=/usr/sbin –sbin-path=/usr/sbin/nginx –conf-path=/etc/nginx/nginx.conf –error-log-path=/var/log/nginx/error.log –pid-path=/var/run/nginx.pid –lock-path=/var/lock/subsys/nginx –http-log-path=/var/log/nginx/access.log
安装py库
easy_install web.py 不用说了 easy_install bpython 一个增强型的python命令行工具,代码提示很不错
安装uwsgi
uwsgi 下载 http://projects.unbit.it/uwsgi/wiki/WikiStart
make 出错, 安装python-devel
make 出错, python setup.py install
安装pylibmc
下面文章讲解了pylibmc的安装过程
link
libevent直接yum安装就可以了,记得安装libevent-devel,不用编译安装
libmemcached 5.0,需要如下编译参数,如果没有据说话报错,另外最好更改一下安装路径,因为so库默认会安装在/usr/local/lib/里,但是so库的查找路径默认没有这个文件夹,当然可以更改一下so的查找路径,有兴趣可以google一下,为了简单,这里直接改安装路径了
./configure –prefix /usr –disable-64bit CFLAGS=”-O3 -march=i686″ –prefix=/usr
下载pylibmc的源码,是上面那个c库的py封装,据说可用性比较强 pylibmc 1.2.0
这个库直接运行python setup.py install就可以了,如果没有出错就安装完成了
安装好以下,在源码路径下有runtest.py,可以测试一下是否安装成功了, 但是测试的时候要确保memcached处于运行状态.
如果提示一下错误按一下nose就可以了
Traceback (most recent call last): File “./runtests.py”, line 15, in import nose ImportError: No module named nose
最后按一下py的mysql库easy_install MySQL-python
之后就是mysql添加用户的配置了 mysql
之后是配置的工作
首先找到nginx的配置文件nginx.conf, 如果是编译安装的话,同级目录下会有一个default的拷贝,所以放心改就是了.
去掉里面的server块,然后include自己的server配置文件.
如我的配置文件/home/user/conf/nginx.conf
就把
server{
listen 80;
……………………
}
替换为
include /home/user/conf/nginx.conf;
自己的server配置文件内容如下:
server{
listen 80;
server_name localhost;
root /home/hao/code/webpy/;
location / {
index index.html;
uwsgi_pass 127.0.0.1:9090;
include uwsgi_params;
}
}
uwsgi程序监听在9090端口, index.py文件内容如下:
import web
urls = (
‘/(.*)’, ‘hello’
)
app = web.application(urls, globals())
class hello:
def GET(self, name):
if not name:
name = ‘World’
return ‘Hello, ‘ + name + ‘!’
application = app.wsgifunc()
注意不是app.run()
uwsgi的启动参数可以去官网看,http://projects.unbit.it/uwsgi/wiki/Doc
下面附带自己的启停脚本
start.sh要记得chmode +x start.sh,给予执行权限.
#!/bin/bash rm log/*.log uwsgi -s :9090 -w index -p 4 -t 10 -M –limit-as 128 -d log/uwsgi.log –harakiri-verbose –listen 10 #–disable-logging memcached -d -vv > log/memcached.11211.log 2>&1 memcached -d -p 11212 -u 11212 -vv > log/memcached.11212.log 2>&1
删除log文件,uwsgi启动监听在9090端口,并且起两个memcached服务器
stop.sh 要记得chmode +x stop.sh,给予执行权限
#!/bin/bash killall -9 uwsgi killall -9 memcached
很粗暴,杀死所有相关进程
restart.sh 同上
#!/bin/bash ./stop.sh ./start.sh
就是掉一下停,再调一下启..
