安装Apache

yum install httpd httpd-devel
service httpd start
/bin/systemctl start httpd.service
systemctl start httpd
service httpd status

安装mysql

MySQL 依赖 libaio，所以先要安装 libaio

yum search libaio # 检索相关信息
yum install libaio # 安装依赖包

检查 MySQL 是否已安装

yum list installed | grep mysq
如果有，就先全部卸载，命令如下
yum -y remove mysql-libs.x86_64

下载 MySQL Yum Repository

wget http://dev.mysql.com/get/mysql-community-release-el7-5.noarch.rpm

安装

添加 MySQL Yum Repository 到你的系统 repository 列表中，执行
yum localinstall mysql-community-release-el7-5.noarch.rpm

验证下是否添加成功

yum repolist enabled | grep "mysql.-community."

选择要启用 MySQL 版本

查看 MySQL 版本，执行

yum repolist all | grep mysql

可以通过类似下面的语句来启动某些版本

yum-config-manager --disable mysql56-community
yum-config-manager --enable mysql57-community-dmr

通过 Yum 来安装 MySQL

yum install mysql-community-server
rpm -qi mysql-community-server.x86_64 0:5.6.24-3.el7
whereis mysql

启动和关闭 MySQL Server

启动 MySQL Server

systemctl start mysqld

查看 MySQL Server 状态

systemctl status mysqld

关闭 MySQL Server

systemctl stop mysqld

防火墙设置

远程访问 MySQL， 需开放默认端口号 3306.

firewall-cmd --permanent --zone=public --add-port=3306/tcp
firewall-cmd --permanent --zone=public --add-port=3306/udp
firewall-cmd --reload

设置字符集

vim /etc/my.cnf
[mysqld]
character_set_server = utf8

[mysql]
default-character-set = utf8

查看字符集

SHOW VARIABLES LIKE 'character%';

安装jdk

yum search java|grep jdk
yum install java-1.7.0-openjdk
//安装完之后，默认的安装目录是在: /usr/lib/jvm/java-1.7.0-openjdk-1.7.0.75.x86_64

配置环境变量

vi /etc/profile

set java environment

JAVA_HOME=/usr/lib/jvm/java-1.7.0-openjdk-1.7.0.75.x86_64
JRE_HOME=$JAVA_HOME/jre
CLASS_PATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar:$JRE_HOME/lib
PATH=$PATH:$JAVA_HOME/bin:$JRE_HOME/bin
export JAVA_HOME JRE_HOME CLASS_PATH PATH

让修改生效

source /etc/profile

如果javac无效

yum install java-devel
