linux环境配置

1.   Ip地址配置 

1.修改主机名

vi /etc/sysconfig/network

NETWORKING=yes

HOSTNAME=node0

2.修改ip地址

vi /etc/sysconfig/network-scripts/ifcfg-eth0

DEVICE=eth0

TYPE=Ethernet

ONBOOT=yes

BOOTPROTO=static

IPADDR=192.168.240.101

NETMASK=255.255.255.0

service network restart

3.修改ip地址和主机名的映射关系

vi /etc/hosts

127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4

::1         localhost localhost.localdomain localhost6 localhost6.localdomain6

192.168.240.101 node0

4.关闭iptables并设置其开机启动/不启动

service iptables stop

chkconfig iptables on

chkconfig iptables off

2.   安装JDK

1.上传jdk-7u45-linux-x64.tar.gz到Linux上

2.解压jdk到/usr/local目录

tar -zxvf jdk-7u45-linux-x64.tar.gz -C /usr/local/

3.设置环境变量，在/etc/profile文件最后追加相关内容

vi /etc/profile

export JAVA_HOME=/usr/local/jdk1.7.0_45

export PATH=$PATH:$JAVA_HOME/bin

4.刷新环境变量

source /etc/profile

5.测试java命令是否可用

java -version

3.   安装Tomcat

1.上传apache-tomcat-7.0.68.tar.gz到Linux上

2.解压tomcat

tar -zxvf apache-tomcat-7.0.68.tar.gz -C /usr/local/

3.启动tomcat

/usr/local/apache-tomcat-7.0.68/bin/startup.sh

4.查看tomcat进程是否启动

jps 

5.查看tomcat进程端口

netstat -anpt | grep 2465

6.通过浏览器访问tomcat

http://192.168.0.101:8080/

4.   安装MySQL

1.上传MySQL-server-5.5.48-1.linux2.6.x86_64.rpm、MySQL-client-5.5.48-1.linux2.6.x86_64.rpm到Linux上

2.使用rpm命令安装MySQL-server-5.5.48-1.linux2.6.x86_64.rpm，缺少perl依赖

rpm -ivh MySQL-server-5.5.48-1.linux2.6.x86_64.rpm

3.安装perl依赖，上传6个perl相关的rpm包

 

rpm -ivh perl-*

4.再安装MySQL-server，rpm包冲突

rpm -ivh MySQL-server-5.5.48-1.linux2.6.x86_64.rpm

 

5.卸载冲突的rpm包

rpm -e mysql-libs-5.1.73-5.el6_6.x86_64 --nodeps

6.再安装MySQL-client和MySQL-server

rpm -ivh MySQL-client-5.5.48-1.linux2.6.x86_64.rpm

rpm -ivh MySQL-server-5.5.48-1.linux2.6.x86_64.rpm

7.启动MySQL服务，然后初始化MySQL

service mysql start

/usr/bin/mysql_secure_installation

8.测试MySQL

mysql -u root -p
