Linux工具安装配置

1、修改主机名/添加别名访问

修改/etc/sysconfig/network中的hostname
NETWORKING=yes
HOSTNAME=dlserver01;

修改/etc/hosts文件

172.16.50.123 dlserver01 # Added by NetworkManager
127.0.0.1 localhost.localdomain localhost
::1 dlserver01 localhost6.localdomain6 localhost6
172.16.50.124 dlserver02
172.16.50.125 dldb01

2、时间设置

设置时区

cp /usr/share/zoneinfo/Asia/Shanghai /etc/localtime

date -R
date -s 20140915
date -s 15:57:30

3、jdk

3.1、

/etc/profile
export JAVA_HOME=/usr/lib/jvm/java-7
export JRE_HOME=${JAVA_HOME}/jre
export CLASSPATH=.:${JAVA_HOME}/lib:${JRE_HOME}/lib
export PATH=${JAVA_HOME}/bin:$PATH

3.2、

chmod 777 bin

source ~/.bashrc
3.3、
java -version

4、tomcat
tar zxvf apache-tomcat-6.0.39.tar.gz
4.1、server.xml 8080 -- 8081

4.2、tomcat-users.xml

<role rolename="tomcat"/>
<role rolename="role1"/>
<role rolename="manager"/>
<role rolename="admin"/>
<user username="tomcat" password="tomcat" roles="tomcat"/>
<user username="both" password="tomcat" roles="tomcat,role1"/>
<user username="role1" password="tomcat" roles="role1"/>
<user username="admin" password="admin" roles="manager"/>

4.2、配置开机自动启动
vi /etc/rc.local

export JAVA_HOME=/usr/lib/jvm/java-7
/dinglicom/tomcat/bin/startup.sh

4.3、其它机器不能访问，开启8080端口或者关闭防火墙

4.3.1、 开启8080端口。
在/ect/sysconfig下编写iptables文件
加入一行
-A RH-Firewall-1-INPUT –m state NEW –m tcp –p tcp –dport 8080 –j ACCEPT
4.3.2、关闭防火墙
(1)关闭立即生效，重启后又开启
service iptables stop
同理：立即开启 service iptable start
(2)重启后生效
chkconfig iptables off
同理：重启后开启 chkconfig service on

第一处端口修改：
<!--  修改port端口：18006 俩个tomcat不能重复，端口随意，别太小-->
<Server port="18006" shutdown="SHUTDOWN">
 
第二处端口修改：
<!-- port="18081" tomcat监听端口，随意设置，别太小 -->
<Connector port="18081" protocol="HTTP/1.1"
connectionTimeout="20000"
redirectPort="8443" />
 
第三处端口修改：
<Connector port="8009" protocol="AJP/1.3" redirectPort="8443" />

5、yum

5.1、http://blog.itpub.net/25313300/viewspace-708509/

wget http://mirrors.163.com/centos/6/os/x86_64/Packages/yum-cron-3.2.29-40.el6.centos.noarch.rpm
wget http://mirrors.163.com/centos/6/os/x86_64/Packages/yum-metadata-parser-1.1.2-16.el6.x86_64.rpm
wget http://mirrors.163.com/centos/6/os/x86_64/Packages/yum-plugin-fastestmirror-1.1.30-14.el6.noarch.rpm
wget http://mirrors.163.com/centos/6/os/x86_64/Packages/python-iniparse-0.3.1-2.1.el6.noarch.rpm

rpm -ivh python-iniparse-0.3.1-2.1.el6.noarch.rpm
rpm -ivh yum-metadata-parser-1.1.2-16.el6.x86_64.rpm
rpm -ivh yum-cron-3.2.29-40.el6.centos.noarch.rpm rpm -ivh yum-plugin-fastestmirror-1.1.30-14.el6.noarch.rpm

5.2、更新repo文件
mv /etc/yum.repos.d/rhel-debuginfo.repo /etc/yum.repos.d/rhel-debuginfo.repo.repo.bak
vi /etc/yum.repos.d/rhel-debuginfo.repo
内容为：
[base]
name=CentOS-$releasever - Base
baseurl=http://mirrors.163.com/centos/6/os/$basearch/
gpgcheck=1
gpgkey=http://mirrors.163.com/centos/RPM-GPG-KEY-CentOS-6

#released updates
[updates]
name=CentOS-$releasever - Updates
baseurl=http://mirrors.163.com/centos/6/updates/$basearch/
gpgcheck=1
gpgkey=http://mirrors.163.com/centos/RPM-GPG-KEY-CentOS-6

#packages used/produced in the build but not released
#[addons]
#name=CentOS-$releasever - Addons
#baseurl=http://mirrors.163.com/centos/$releasever/addons/$basearch/
#gpgcheck=1
#gpgkey=http://mirrors.163.com/centos/RPM-GPG-KEY-CentOS-6
#additional packages that may be useful
[extras]
name=CentOS-$releasever - Extras

gpgcheck=1
gpgkey=http://mirrors.163.com/centos/RPM-GPG-KEY-CentOS-6
#additional packages that extend functionality of existing packages
[centosplus]
name=CentOS-$releasever - Plus
baseurl=http://mirrors.163.com/centos/6/centosplus/$basearch/
gpgcheck=1
enabled=0

6、MySQL（linux下使用yum安装mysql）

1、安装
查看有没有安装过：
yum list installed mysql*
rpm -qa | grep mysql*

查看有没有安装包：
yum list mysql*

安装mysql客户端：
yum install mysql

安装mysql 服务器端：
yum install mysql-server
yum install mysql-devel

2、启动&&停止

数据库字符集设置
mysql配置文件/etc/my.cnf中加入default-character-set=utf8

启动mysql服务：
service mysqld start或者/etc/init.d/mysqld start
停止：
service mysqld stop

开机启动

chkconfig --list

> chkconfig mysqld off

> chkconfig mysqld on

2、登录

创建root管理员：
mysqladmin -u root password zxc

登录：
mysql -u root -p输入密码即可。
忘记密码：
service mysqld stop
mysqld_safe --user=root --skip-grant-tables
mysql -u root
use mysql
update user set password=password("new_pass") where user="root";
flush privileges;

3、远程访问
开放防火墙的端口号
mysql增加权限：mysql库中的user表新增一条记录host为“%”，user为“root”。

4、Linux MySQL的几个重要目录
数据库目录
/var/lib/mysql/
配置文件
/usr/share /mysql（mysql.server命令及配置文件）
相关命令
/usr/bin（mysqladmin mysqldump等命令）
启动脚本
/etc/rc.d/init.d/（启动脚本文件mysql的目录）

7、nginx

7.1、rpm -ivh http://nginx.org/packages/centos/6/noarch/RPMS/nginx-release-centos-6-0.el6.ngx.noarch.rpm

7.2、查看yum的nginx信息

yum info nginx

7.3、安装并启动nignx

[root@server ~]# yun install nignx
[root@server ~]# service nginx start
Starting nginx:                                            [  OK  ]

7.4、然后进入浏览器，输入http://192.168.128.134/测试，如果看到

Welcome to nginx!

If you see this page, the nginx web server is successfully installed and working. Further configuration is required.

For online documentation and support please refer to nginx.org.
Commercial support is available at nginx.com.

Thank you for using nginx.

恭喜你，你成功了！

nginx.conf

upstream 192.168.128.137{
    server 192.168.128.137:8081;
    #server 192.168.128.137:9081;
}
server {
    listen       80;
    server_name  192.168.128.137;
    location / {
        #root   /dsm;
        index  index.html index.htm index.jsp;
        proxy_connect_timeout   3;
        proxy_send_timeout      30;
        proxy_read_timeout      30;
        proxy_pass http://192.168.128.137;
    }
}

-- 停止

nginx -s stop

-- 重启

/usr/sbin/nginx

-- 验证

nginx -t

问题：还是不晓得怎么配置到tomcat里的具体应用

7、web.py

wget http://webpy.org/static/web.py-0.37.tar.gz

python setup.py install

安装flup来提供WSGI接口（WSGI是Python应用程序和Web服务器之间的一种接口，类似于java的Servlet

wget http://www.saddi.com/software/flup/dist/flup-1.0.2.tar.gz

python setup.py install

-- 数据库

http://initd.org/psycopg/ 下载psycopg2-2.5.4.tar.gz

yum install postgresql-server

yum install postgresql-devel

8、nmon

chmod 777 nmon

./nmon –fT –s 5 –c 100
