centos 安装mysql,tomcat,jdk

以前用的公共的高配centos，环境什么都好，最近花了10块钱买了个屌丝阿里云，配环境配了好久，写下来以后自己看，。。。

我的环境JDK+TOMCAT+MYSQL

// 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
　　<Connector port="8080" protocol="HTTP/1.1"
connectionTimeout="20000"
redirectPort="8443"
URIEncoding="UTF-8" />

//3安装mysql。。。搞了好久，阿里云yum没有

# 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_connect='SET NAMES utf8'
