本篇文章主要介绍了"centOs安装配置jdk+mysql+tomcat"，主要涉及到方面的内容，对于MySql感兴趣的同学可以参考一下： 更换yum1] 首先备份/etc/yum.repos.d/CentOS-Base.repomv /etc/yum.repos.d/CentOS-Base.rep...

更换yum

1] 首先备份/etc/yum.repos.d/CentOS-Base.repo

mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.backup
[2] 进入yum源配置文件所在文件夹

[root@localhost yum.repos.d]# cd /etc/yum.repos.d/
[3] 下载163的yum源配置文件，放入/etc/yum.repos.d/(操作前请做好相应备份)

[root@localhost yum.repos.d]# wget http://mirrors.163.com/.help/CentOS6-Base-163.repo
[4] 运行yum makecache生成缓存

[root@localhost yum.repos.d]# yum makecache
[5] 更新系统

[root@localhost yum.repos.d]# yum -y update

# 1. 安装JDK  

yum list java*  
yum install java-1.7.0-openjdk* -y 

//2安装Tomcat 先上传到usr/local下
   

 #cd /usr/local/ /再执行下面的命令
　　#tar zxvf apache-tomcat-7.0.64.tar.gz /解压
　　#mv apache-tomcat-7.0.64 tomcat7 /更名
　　#cd /usr/local//tomcat7/bin/ /打开此目录
　　#chmod 777 *.sh /加777权限
　　#bash catalina.sh start /启动

    //设置service.xml为utf-8

    //mysql

# yum install  mysql mysql-server mysql-libs mysql-server;
# mysqladmin -u root password ''   /设置密码
# service mysqld start  //启动
# chkconfig mysqld on  //设置开机启动
# chkconfig --list | grep mysql
# mysqladmin -u root password ''  //设置密码
GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY '' WITH GRANT OPTION;   //设置允许navicate

update user set password=password('123456') where user='';

# wget http://repo.mysql.com/mysql-community-release-el7-5.noarch.rpm  //三步安装
# sudo rpm -ivh mysql-community-release-el7-5.noarch.rpm
# sudo yum install mysql-server
# mysql -u root            //基本配置
# sudo chown -R openscanner:openscanner /var/lib/mysql      //把/var/lib/mysql的拥有者改为当前用户
# service mysqld restart
# chkconfig mysqld on     //设置开机启动
# mysql -u root
mysql>>use mysql;
       update user set password=password(‘123456‘) where user=‘root‘;
       GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY '' WITH GRANT OPTION;

最后centos ，mysql区分大小写，所以设置 
etc/my.cnf 设置不区分大小写，并且设置UTF-8

[mysqld]
lower_case_table_names=1
character_set_server=utf8  
init_c NAMES utf8' 

以上就介绍了centOs安装配置jdk+mysql+tomcat，包括了方面的内容，希望对MySql有兴趣的朋友有所帮助。
