centos6.5实践（2）：搭建Java Web生产环境

来源：互联网发布：ftp服务器默认端口号编辑：程序博客网时间：2024/04/30 15:11

准备工作

已安装centos 6.5系统
jdk下载，笔者下的是rpm版的
Tomcat下载，笔者下的是tar.gz版的

做法

安装jdk

mkdir /usr/java

sudo mv ‘/home/weijiang/Desktop/jdk-8u73-linux-x64.rpm’ /usr/java

note:
可自行选择安装方式(rpm or tar.gz)
tar -zxvf jdk-8u73-linux-x64.tar.gz // 将之前下载的jdk解压缩并安装

cd /usr/java
sudo rpm -ivh jdk-8u73-linux-x64.rpm

note:
i是安装，v是校验，h是散列的显示安装进度

在profile文件中加入java环境变量
vi /etc/profile

export JAVA_HOME=/usr/java/jdk1.8.0_73 export CLASSPATH=.:%JAVA_HOME%/lib/dt.jar:%JAVA_HOME%/lib/tools.jar  export PATH=$PATH:$JAVA_HOME/bin

JAVA_HOME=/usr/java/jdk1.8.0_73CLASSPATH=$JAVA_HOME/lib:$JAVA_HOME/jre/libPATH=$PATH:$JAVA_HOME/bin:$JAVA_HOME/jre/binexport PATH CLASSPATH JAVA_HOME

使文件立即生效
source /etc/profile //或者reboot
检测是否安装成功

java -version  // 出现下面的信息则表示安装成功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)

安装Tomcat

mv ‘/home/weijiang/Desktop/apache-tomcat-8.0.33.tar.gz’ /usr/local
tar -zxvf apache-tomcat-8.0.33.tar.gz
mv apache-tomcat-8.0.33 tomcat8 // 重命名
cd /usr/local/tomcat8/bin/
./startup.sh
note：无法访问时，关闭防火墙
service iptables stop
设置tomcat开机自启动

gedit /etc/rc.d/rc.local // 打开rc.local文件文件最后增加内容(假设JDK目录是/usr/java，Tomcat目录是/usr/local/tomcat)：export JDK_HOME=/usr/java/jdk1.7.0  export JAVA_HOME=/usr/java/jdk1.7.0  /usr/local/tomcat/bin/startup.sh note:1.使用gedit可能出现No protocol specified (gedit:14333): Gtk-WARNING **: cannot open display: :0.0错误,[解决方案](http://blog.csdn.net/wche1990/article/details/8153248)2.rc.local先于/etc/profile执行，所以会得不到JAVA环境变量，所以在startup.sh前加入代码JAVA_HOME

安装MySQL

由于新安装的CentOS系统默认一般都装有MySQL，检测系统是否自带安装mysql

yum list installed | grep mysqlorrpm -qa | grep mysql

如果有安装MySQL，删除系统自带的mysql及其依赖

yum -y remove mysql-libs.x86_64

查看系统里面有没有mysql 的repo

yum repolist all | grep mysql

如果没有发现，则需要配置repo

vim /etc/yum.repos.d/mysql-community.repo  // 打开repo文件

# Enable to use MySQL 5.6[mysql56-community]name=MySQL 5.6 Community Serverbaseurl=http://repo.mysql.com/yum/mysql-5.6-community/el/6/$basearch/enabled=1gpgcheck=1gpgkey=

再次检查是否存在mysql的repo

# yum repolist enabled | grep mysql出现mysql56-community   MySQL 5.6 Community Server    248 即成功

安装MySQLyum install mysql-community-server
如果出现如下错误，则安装失败，失败处理参考；否则一路选择Y下去

mysql-community-server-5.6.28-2.el6.x86_64.rpm     |  53 MB     00:10     warning: rpmts_HdrFromFdno: Header V3 DSA/SHA1 Signature, key ID 5072e1f5: NOKEYRetrieving key from file:///etc/pki/rpm-gpg/RPM-GPG-KEY-mysql获取 GPG 密钥失败：[Errno 14] Could not open/read file:///etc/pki/rpm-gpg/RPM-GPG-KEY-mysql

一般会出现如下警告，解决方法如下
note:Public key for mysql-community-client-5.6.30-2.el6.x86_64.rpm is not installed

rpm --import /etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-6(我的版本是CentOS6.5)查看centos版本命令 cat /etc/centos-release

一般这个方法是没用的。笔者的处理如下：
1 进入cd /etc/pki/rpm-gpg
2 新建一个RPM-GPG-KEY-mysql文件cp -b RPM-GPG-KEY-CentOS-6 RPM-GPG-KEY-mysql
3 在RPM-GPG-KEY-mysql中写入如下内容

4 修改第四步的repo内容

# Enable to use MySQL 5.6[mysql56-community]name=MySQL 5.6 Community Serverbaseurl=http://repo.mysql.com/yum/mysql-5.6-community/el/6/$basearch/enabled=1gpgcheck=1gpgkey=file:/etc/pki/rpm-gpg/RPM-GPG-KEY-mysql

5 执行第6步,一路选择Y下去

启动MySQL

service mysqld start   --启动service mysqld stop    --停止service mysqld status  --状态

查看mysql是否自启动,并且设置开启自启动

chkconfig --list | grep mysqldchkconfig mysqld on

可以看到有7个level水平
note：引用于网络

 等级0表示：表示关机 等级1表示：单用户模式 等级2表示：无网络连接的多用户命令行模式 等级3表示：有网络连接的多用户命令行模式 等级4表示：不可用 等级5表示：带图形界面的多用户模式 等级6表示：重新启动 chkconfig –level 12 httpd on  将Level1和Level2设置成on

初始化root密码

mysqladmin -u root password 123456 // 初始化root密码

设置root新密码

mysqladmin -u root -p 123456(初始密码) newpassword(新密码) //修改root密码

登录MySQL

mysql -u root -p  // 登录MySQLshow databases;  // 显示数据库use mysql; // 进入mysql数据库select host,user from user;  // 查看主机暨对应的用户，前提是进入某个数据库

允许远程登录(详情参考)

grant all privileges on *.* to 'root'@'%' with grant option; FLUSH PRIVILEGES; // 重载授权表：exit // 退出数据库service mysqld restart  // 重启mysql数据库netstat -ntlp  // 查看mysql的端口是否为3306自己用本地测试远程连接，笔者用的是MySQLWorkbench客户端如果连接不上，记得先关掉下防火墙测试下service iptables restart/stop/start 关掉防火墙后可以连接，则是端口问题方案1/sbin/iptables -I INPUT -p tcp --dport 3306 -j ACCEPT  // 开放端口:3306/etc/rc.d/init.d/iptables save  // 保存/etc/init.d/iptables restart  or  service iptables restart // 重启防火墙方案2：1. gedit /etc/sysconfig/IPtables 2. 新增一行-A RH-Firewall-1-INPUT -m state –state NEW -m tcp -p tcp –dport 8080 -j ACCEPT3.service iptables restart

上面的步奏执行完后，迎接success的喜悦吧…
笔者的远程操作简图如下（基于MySQLWorkbench客户端）:
1. 登录数据库

2. 进行数据库的某些操作

3. centos数据库查看

安装Redis

待续~

安装Nginx

待续~
