Linux服务器配置（一）

jdk,tomcat,nginx记录

最近公司买了三台服务器System x3650 M5用来跑公司的项目。现，记录一下真机部署与后期维护历程~

因为系统是服务器买来就装好的，所以避免不了有一些不符合应用场景的程序，服务等，首先使用yum grouplist命令来看看当前系统中已经包含哪些东西~

系统默认安装了java平台，看看是不是我们想要的。

[root@hart ~]# java -version

java version "1.7.0_45"

OpenJDK Runtime Environment (rhel-2.4.3.3.el6-x86_64 u45-b15)

OpenJDK 64-Bit Server VM (build 24.45-b08, mixed mode)

原来安装的是OpenJDK,好吧。我们自己动手换成我们自己常用的oracle jdk.那么首先我们要将OpenJDK卸载。

[root@hart ~]# rpm -qa | grep jdk

java-1.7.0-openjdk-1.7.0.45-2.4.3.3.el6.x86_64

java-1.6.0-openjdk-1.6.0.0-1.66.1.13.0.el6.x86_64

[root@hart ~]# yum -y remove java-1.6.0-openjdk-1.6.0.0-1.66.1.13.0.el6.x86_64 java-1.7.0-openjdk-1.7.0.45-2.4.3.3.el6.x86_64

....

....

....

Complete!

[root@hart ~]#

ok 卸载完成。

http://www.oracle.com/technetwork/java/javase/downloads/index.html

自行下载jdk



[root@hart hart]# tar -zxvf jdk-7u80-linux-x64.gz //解压jdk到当前目录下

[root@hart hart]# mkdir /usr/java

[root@hart hart]# mv jdk1.7.0_80/ /usr/java/jdk1.7

[root@hart jdk1.7]# vi /etc/profile

//在文件最后面添加

export JAVA_HOME=/usr/java/jdk1.7/

export PATH=$PATH:$JAVA_HOME\bin

export CLASSPATH=.

//保存 退出 :wq

[root@hart jdk1.7]# source /etc/profile

[root@hart jdk1.7]# java

[root@hart jdk1.7]# javac

[root@hart jdk1.7]# java -version

java version "1.7.0_80"

Java(TM) SE Runtime Environment (build 1.7.0_80-b15)

Java HotSpot(TM) 64-Bit Server VM (build 24.80-b11, mixed mode)

Ok~JDK安装配置完成。下面安装tomcat

[root@hart tomcat]# ls

apache-tomcat-7.0.69.tar.gz

[root@hart tomcat]# tar -zxvf apache-tomcat-7.0.69.tar.gz

[root@hart tomcat]# ls

apache-tomcat-7.0.69  apache-tomcat-7.0.69.tar.gz

[root@hart tomcat]# mv apache-tomcat-7.0.69 tomcat7.0

[root@hart tomcat]# ls

apache-tomcat-7.0.69.tar.gz  tomcat7.0

配置tomcat

[root@hart tomcat]# cd tomcat7.0/conf/

[root@hart conf]# ls

catalina.policy      context.xml         server.xml        web.xml

catalina.properties  logging.properties  tomcat-users.xml

[root@hart conf]# vi server.xml

<Connector port="8080" protocol="HTTP/1.1"

               connectionTimeout="20000"

               redirectPort="8443" URIEncoding="UTF-8" />

//port自行修改，最后加上URIEncoding="UTF-8"可以避免地址栏路径中文乱码问题

//在<Host>标签中添加以下代码，可以使tomcat访问虚拟路径

<Context docBase="/usr/filePath" path="/file" />

//此外,在context.xml中配置也可以

[root@hart conf]# vi web.xml

<servlet>

        <servlet-name>default</servlet-name>

        <servlet-class>org.apache.catalina.servlets.DefaultServlet</servlet-class>

        <init-param>

            <param-name>debug</param-name>

            <param-value>0</param-value>

        </init-param>

        <init-param>

            <param-name>listings</param-name>

            <!-- 将false改为true-->

            <param-value>true</param-value>

        </init-param>

        <load-on-startup>1</load-on-startup>

    </servlet>

Ok,安装nginx

[root@hart nginx]# ls

nginx-1.8.1.tar.gz

[root@hart nginx]# tar -zxvf nginx-1.8.1.tar.gz

[root@hart nginx]# cd nginx-1.8.1

[root@hart nginx-1.8.1]# ./configure

[root@hart nginx-1.8.1]# ./configure

checking for OS

 + Linux 2.6.32-431.el6.x86_64 x86_64

checking for C compiler ... not found

./configure: error: C compiler cc is not found

//没有gcc,安装

[root@hart nginx-1.8.1]# yum -y install gcc

Complete!

[root@hart nginx-1.8.1]# ./configure

./configure: error: the HTTP rewrite module requires the PCRE library.

You can either disable the module by using --without-http_rewrite_module

option, or install the PCRE library into the system, or build the PCRE library

statically from the source with nginx by using --with-pcre=<path> option.

//安装pcre-devel

[root@hart nginx-1.8.1]# yum install pcre-devel

Total download size: 516 k

Is this ok [y/N]: y

Complete!

[root@hart nginx-1.8.1]# ./configure

./configure: error: the HTTP gzip module requires the zlib library.

You can either disable the module by using --without-http_gzip_module

option, or install the zlib library into the system, or build the zlib library

statically from the source with nginx by using --with-zlib=<path> option.

//哎= =！安装zlib-devel

[root@hart nginx-1.8.1]# yum -install zlib-devel

Total download size: 44 k

Installed size: 115 k

Is this ok [y/N]: y

Complete!

[root@hart nginx-1.8.1]# ./configure

Configuration summary

  + using system PCRE library

  + OpenSSL library is not used

  + using builtin md5 code

  + sha1 library is not found

//终于哦了~~~make

[root@hart nginx-1.8.1]# make install

nginx代理tomcat

//在/usr/local/nginx/conf/nginx.conf中:

//配置tomcat节点:在http节点内部,server节点外部

	upstream tomcat-servers {

		server ip:tomcatport;

	}

//server节点内部:

	location / {

		proxy_pass http://tomcat-servers;

		proxy_redirect    off;

		proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

		proxy_set_header X-Real-IP $remote_addr;

		proxy_set_header Host $http_host;

		proxy_next_upstream http_502 http_504 error timeout invalid_header;

	}

只是现在从别的机器还访问不了，怎么办呢？

[root@hart sbin]# vi /etc/rc.d/init.d/iptables

//加入以下这条规则

-A INPUT -m state --state NEW -m tcp -p tcp --dport 80 -j ACCEPT

[root@hart sbin]# service iptables restart

ok.这样就可以访问啦~~

先这样简单的记录一下步骤。深入的运维管理，让我们一起慢慢学习。
