[root@Web-175 ~]# uname -a
Linux Web-175 2.6.32-220.el6.x86_64 #1 SMP Tue Dec 6 19:48:22 GMT 2011 x86_64 x86_64 x86_64 GNU/Linux
[root@Web-175 ~]# cat /etc/issue
CentOS release 6.2 (Final)
Kernel \r on an \m所需软件版本：（由于线上跑的的是之前搭建的老环境，为了避免因版本不同，出现问题，安装的就与之前的版本一致了）apache-tomcat-7.0.29.tar.gz
jdk-6u25-linux-x64.bin
nginx-0.8.33.tar.gz二、nginx+tomcat环境搭建1.安装gcc编译器及相关工具和依赖库：[root@Web-175 ~]# yum -y install gcc gcc-c++ autoconf libjpeglibjpeg-devel libpng libpng-devel freetype freetype-devel libxml2 libxml2-develzlib zlib-devel glibc glibc-devel glib2 glib2-devel bzip2 bzip2-devel ncursesncurses-devel curl curl-devel e2fsprogs e2fsprogs-devel krb5 krb5-devel libidnlibidn-devel openssl openssl-devel openldap openldap-devel nss_ldapopenldap-clients nfs-utils make patch openldap-servers2.系统基本限制vim /etc/security/limits.conf (在行尾添加)
* soft noproc 10240
* hard noproc 10240
* soft nofile 65536
* hard nofile 65536
# End of file说明： * 代表针对所有用户noproc 是代表最大进程数nofile 是代表最大文件打开数（1）limits.conf描述limits.conf文件实际是Linux PAM（插入式认证模块，Pluggable AuthenticationModules）中 pam_limits.so 的配置文件，而且只针对于单个会话（2）limits.conf工作原理limits.conf是 pam_limits.so的 配置文件，然后/etc/pam.d/下的应用程序调用pam_***.so模块。譬如说，当用户 访问服务器，服务程序将请求发送到PAM模块，PAM模块根据服务名称在/etc/pam.d目 录下选择一个对应的服务文件，然后根据服务文件的内容选择具体的PAM模块进行处理3.修改一下linux操作系统的登陆配置文件打开/etc/pam.d/login这个配置文件
在最后添加一行内容
session required /lib64/security/pam_limits.so
# tail -1 /etc/pam.d/login
session required /lib64/security/pam_limits.so4.关闭防火墙和selinux.# /etc/init.d/iptables stop
[root@Web-175 ~]# setenforce 05.安装jdk.[root@Web-175 opt]#chmod +x jdk-6u25-linux-x64.bin
[root@Web-175 opt]# ./jdk-6u25-linux-x64.bin
[root@Web-175 opt]# tar -zxvf apache-tomcat-7.0.29.tar.gz
[root@Web-175 opt]# mv apache-tomcat-7.0.29 tomcat36.设置系统环境变量.[root@Web-175 opt]# vim /etc/profile(在末尾添加三行代码，设置系统环境变量)
export CLASSPATH=".:/opt/jdk1.6.0_25/jre/lib/rt.jar:/opt/jdk1.6.0_25/lib/dt.jar:/opt/jdk1.6.0_25/lib/tools.jar"
export PATH=$PATH:/opt/jdk1.6.0_25/bin
export JAVA_HOME="/opt/jdk1.6.0_25"
[root@Web-175 opt]# source /etc/profile 让变量生效7.修改tomcat的server.xml文件（修改端口为9080，并且添加memcache共享session）[root@Web-175 conf]# vim /opt/tomcat3/conf/server.xml
<Connector port="9080"protocol="HTTP/1.1"
connectionTimeout="20000"
URIEncoding="utf-8"
redirectPort="8443"
maxThreads="500" />
<Context path=""docBase="/opt/newWebshop" useHttpOnly="false">
<ManagerclassName="de.javakaffee.web.msm.MemcachedBackupSessionManager"
copyCollectionsForSerialization="false"
sessionBackupTimeout="100"
sessionBackupAsync="false"
sticky="false"
requestUriIgnorePattern=".*\.(ico|png|gif|jpg|css|js)$"
memcachedNodes="n1:192.168.5.11:11211,n2:192.168.5.15:11211"/>
</Context>8.增加虚拟机可以使用的最大内存[root@Web-175 conf]# vim ../bin/catalina.sh +99在99行，添加下边这段代码JAVA_OPTS="-server -Djava.awt.headless=true -Xms728m-Xmx1024m -XX:PermSize=128m -XX:MaxPermSize=256m"注意：tomcat中lib目录下的jar包，要跟174和176服务器上的一样，要是不一样，可以直接从174或176上拷贝一份。[root@Web-175 tomcat3]# ls ../lib/
annotations-api.jar ecj-3.7.2.jar memcached-session-manager-1.6.3.jar tomcat-coyote.jar tomcat-jdbc.jar
catalina-ant.jar el-api.jar memcached-session-manager-tc7-1.6.3.jar tomcat-dbcp.jar tomcat-util.jar

catalina-tribes.jar jsp-api.jar tomcat-api.jar tomcat-i18n-ja.jar
[root@Web-175 conf]# cd ../webapps/
[root@Web-175 webapps]# ls
host-manager manager ROOT
webapps下只要三个文件就可以,其余的可以删除9.安装nginx编译安装pcre库PCRE(Perl Compatible RegularExpressions)是一个Perl库，包括 perl 兼容的正规表达式。Pcre的作用主要是使nginx支持HTTPrewrite模块。[root@Web-175 ~]# cd /opt/
[root@Web-175 opt]# tar -zxvf pcre-7.6.tar.gz
[root@Web-175 pcre-7.6]# ./configure
[root@Web-175 pcre-7.6]# make && make install编译安装jpegJpeg是一个基本的图像压缩方式。[root@Web-175 opt]# tar -zxvf jpegsrc.v7.tar.gz
[root@Web-175 opt]# cd jpeg-7/
[root@Web-175 opt]# ./configure --enable-shared --enable-static
[root@Web-175 opt]# make && make install创建nginx用户和组useradd -s /sbin/nologin -M nginx
groupadd ngnix
[root@Web-175 opt]# tar -zxvfnginx-upstream-jvm-route-0.2.tar.gz
[root@Web-175 opt]# tar -zxvf nginx-0.8.33.tar.gz
[root@Web-175 opt]# mv nginx-0.8.33 nginx5
[root@Web-175 opt]# cd nginx5实现基于 Cookie 的 Session Sticky 的功能patch -p0 < /opt/nginx_upstream_jvm_route/jvm_route.patch编译安装nginx
[root@Web-175 nginx5]# ./configure --prefix=/opt/nginx6--with-http_stub_status_module --with-pcre=/opt/pcre-7.6--add-module=../nginx_upstream_jvm_route/ --with-openssl=/usr/bin/openssl
[root@Web-175 nginx5]# make && make install为了方便，直接可以拷贝174或176上的nginx.conf的配置文件修改下代理转发的端口即可.[root@Web-175 nginx5]# catnginx6/conf/nginx.conf

从tomcat的日志来看，是正常的，说明tomcat正常开启，而且运行正常。到此为止，nginx+tomcat的环境，已经搭建完毕。测试：
测试正常，说明nginx结合tomcat，安装成功了。我想为Heroku构建一个Rails3应用程序。他们使用Postgres作为他们的数据库，所以我通过MacPorts安装了postgres9.0。现在我需要一个postgresgem并且共识是出于性能原因你想要pggem。但是我对我得到的错误感到非常困惑当我尝试在rvm下通过geminstall安装pg时。我已经非常明确地指定了所有postgres目录的位置可以找到但仍然无法完成安装:$envARCHFLAGS='-archx86_64'geminstallpg--\--with-pg-config=/opt/local/var/db/postgresql90/defaultdb/po
我正在使用的第三方API的文档状态:"[O]urAPIonlyacceptspaddedBase64encodedstrings."什么是“填充的Base64编码字符串”以及如何在Ruby中生成它们。下面的代码是我第一次尝试创建转换为Base64的JSON格式数据。xa=Base64.encode64(a.to_json) 最佳答案 他们说的padding其实就是Base64本身的一部分。它是末尾的“=”和“==”。Base64将3个字节的数据包编码为4个编码字符。所以如果你的输入数据有长度n和n%3=1=>"=="末尾用于填充n%
我打算为ruby脚本创建一个安装程序，但我希望能够确保机器安装了RVM。有没有一种方法可以完全离线安装RVM并且不引人注目(通过不引人注目，就像创建一个可以做所有事情的脚本而不是要求用户向他们的bash_profile或bashrc添加一些东西)我不是要脚本本身，只是一个关于如何走这条路的快速指针(如果可能的话)。我们还研究了这个很有帮助的问题:RVM-isthereawayforsimpleofflineinstall?但有点误导，因为答案只向我们展示了如何离线在RVM中安装ruby。我们需要能够离线安装RVM本身，并查看脚本https://raw.github.com/wayn

我刚刚为fedora安装了emacs。我想用emacs编写ruby。为ruby提供代码提示、代码完成类型功能所需的工具、扩展是什么？ 最佳答案 ruby-mode已经包含在Emacs23之后的版本中。不过，它也可以通过ELPA获得。您可能感兴趣的其他一些事情是集成RVM、feature-mode(Cucumber)、rspec-mode、ruby-electric、inf-ruby、rinari(用于Rails)等。这是我当前用于Ruby开发的Emacs配置:https://github.com/citizen428/emacs
我的瘦服务器配置了nginx，我的ROR应用程序正在它们上运行。在我发布代码更新时运行thinrestart会给我的应用程序带来一些停机时间。我试图弄清楚如何优雅地重启正在运行的Thin实例，但找不到好的解决方案。有没有人能做到这一点？ 最佳答案 #Restartjustthethinserverdescribedbythatconfigsudothin-C/etc/thin/mysite.ymlrestartNginx将继续运行并代理请求。如果您将Nginx设置为使用多个上游服务器，例如server{listen80;server
