因系统Ubuntu12.04，官方源能升级到最新的PHP版本为5.3.10，感觉版本太旧有漏洞，所以决定编译升级到最新的nginx和php。下面是安装笔记。

注：MySQL用的依然是源里的二进制包，编译MySQL耗时太久，所以就放弃了。

1.编译安装Nginx

#安装nginx依赖
apt-get install build-essential libpcre3-dev libssl-dev
wget http://nginx.org/download/nginx-1.5.4.tar.gz
tar -zxf nginx-1.5.4.tar.gz
cd nginx-1.5.4/
./configure --with-http_ssl_module
make
make install

安装后默认目录在/usr/local/nginx，执行/usr/local/nginx/sbin/nginx 测试是否安装成功。

2.编译安装PHP

#安装PHP依赖，重要
apt-get install libiconv-hook-dev libmcrypt-dev libxml2-dev libmysqlclient-dev libcurl4-openssl-dev libjpeg8-dev libpng12-dev libfreetype6-dev

#下载源码，用的是美国镜像
wget -O php5.5.3.tar.gz http://cn2.php.net/get/php-5.5.3.tar.gz/from/us1.php.net/mirror
tar -zxf php5.5.3.tar.gz
cd php-5.5.3/

#配置，MySql用的是mysqlnd
./configure -prefix=/usr/local/php --with-config-file-path=/usr/local/php/etc --with-iconv-dir --with-freetype-dir --with
-jpeg-dir --with-png-dir --with-zlib --with-libxml-dir=/usr -enable-xml -disable-rpath -enable-bcmath -enable-shmop -enable-sysv
sem -enable-inline-optimization --with-curl  -enable-mbregex -enable-fpm -enable-mbstring --with-mcrypt -enable-ftp --with-gd -e
nable-gd-native-ttf --with-openssl --with-mhash -enable-pcntl -enable-sockets --with-xmlrpc -enable-zip -enable-soap --without-p
ear --with-gettext --with-mysqli=mysqlnd --with-mysql=mysqlnd --with-pdo-mysql

make
make install

默认安装目录在/usr/local/php

3.配置nginx+php

#进入/usr/local/php/etc目录，复制一份php-fpm配置
cp php-fpm.conf.default php-fpm.conf

#从源码目录复制一份php.ini文件到/usr/local/php
cp {PHP_SOURCE_PATH}/php.ini-production /usr/local/php/etc/php.ini

#准备php-fpm服务脚本
cp {PHP_SOURCE_PATH}/sapi/fpm/init.d.php-fpm /etc/init.d/php-fpm
chmod +x /etc/init.d/php-fpm

 4.结束

启动php-fpm
/etc/init.d/php-fpm start

启动nginx
/usr/local/nginx/sbin/nginx

最后收尾工作就是权限配置和nginx的站点配置了。

禁用掉终端CTRL+S快捷键功能
“CTRL-S：挂起终端（XON）
“CTRL-Q：恢复终端（XOFF）
“要禁止这些键盘映射，在~/.bashrc中加入
stty -ixon
然后修改vim中的按键映射，在 ~/.vimrc中加入

nmap <C-S> :update<CR>
vmap <C-S> <C-C>:update<CR>
imap <C-S> <C-O>:update<CR>

错误大概是：

这是个bug，打上补丁即可解决

USAssh.com 最早成立于2009年，是一家注重用户体验、高速稳定、诚信专业、老牌资深的美国SSH代理服务提供商，专注于给用户提供优质稳定的SSH代理和VPN代理服务。

2012-7-23 update：更新ruby获取密码脚本！

最近发现usassh提供的有免费测试，美中不足的是每整点更换密码。经过摸索自己写了个脚本实现自动抓取密码并自动重新连接。(如果您觉得服务不错，请购买付费账户，也算支持别人的工作 🙂 )

脚本使用了工具expect，Ubuntu用户可以用sudo apt-get install expect安装。

1.expect脚本内容如下，主要实现自动登录的处理。

有时候用root登录或者一些Server版的Ubuntu中遇到过apt-get install安装新包时，输入包名前几个字符按TAB建无法自动匹配提示，只需按下面方法解决便可。

1. 安装bash-completion包。apt-get install bash-completion
2. 加载环境。source /etc/bash_completion

apt-get install autoconf=2.50

更改keymap设置为非Eclipse即可解决。

关于SSH动态转发变成Socket代理情况这里就不说了。

本文适用于：

假如你有一台国外的SSH主机C(目的大家都懂～ o(∩∩)o…)，自己电脑A用SSH做代理访问C网络状况不佳，时不时丢包，或者速度特别慢的时候。

同时需要主机B，与A和C连接速度都很快，一般是国内主机。

1. SSH登录B，执行：
   ssh -g -D 9001 C用户@C主机IP
   会自动监听9001端口接受下一步发来的数据。
2. SSH登录A，执行：
   ssh -g -L 9000:localhost:9001 B用户名@B主机IP
   开启本地端口转发，将会在A主机开启9000端口，发往9000端口的数据会经过SSH隧道转发到B机本地的9001端口，同时B机的ssh会再次把数据转发往第一步的C主机。

然后在A本机设置FireFox或者其他应用程序的Socks代理为127.0.0.1:9000即可上网。
