安裝Apache
yum install httpd httpd-devel
service httpd start
/bin/systemctl start httpd.service
systemctl start httpd
service httpd status
安裝mysql
MySQL 依賴 libaio，所以先要安裝 libaio
yum search libaio # 檢索相關(guān)信息
yum install libaio # 安裝依賴包
檢查 MySQL 是否已安裝
yum list installed | grep mysq
如果有，就先全部卸載，命令如下
yum -y remove mysql-libs.x86_64
下載 MySQL Yum Repository
wget http://dev.mysql.com/get/mysql-community-release-el7-5.noarch.rpm
安裝
添加 MySQL Yum Repository 到你的系統(tǒng) repository 列表中，執(zhí)行
yum localinstall mysql-community-release-el7-5.noarch.rpm
驗(yàn)證下是否添加成功
yum repolist enabled | grep "mysql.-community."
選擇要啟用 MySQL 版本
查看 MySQL 版本，執(zhí)行
yum repolist all | grep mysql
可以通過類似下面的語(yǔ)句來啟動(dòng)某些版本
yum-config-manager --disable mysql56-community
yum-config-manager --enable mysql57-community-dmr
通過 Yum 來安裝 MySQL
yum install mysql-community-server
rpm -qi mysql-community-server.x86_64 0:5.6.24-3.el7
whereis mysql
啟動(dòng)和關(guān)閉 MySQL Server
啟動(dòng) MySQL Server
systemctl start mysqld
查看 MySQL Server 狀態(tài)
systemctl status mysqld
關(guān)閉 MySQL Server
systemctl stop mysqld
防火墻設(shè)置
遠(yuǎn)程訪問 MySQL， 需開放默認(rèn)端口號(hào) 3306.
firewall-cmd --permanent --zone=public --add-port=3306/tcp
firewall-cmd --permanent --zone=public --add-port=3306/udp
firewall-cmd --reload
設(shè)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%';
安裝jdk
yum search java|grep jdk
yum install java-1.7.0-openjdk
//安裝完之后，默認(rèn)的安裝目錄是在: /usr/lib/jvm/java-1.7.0-openjdk-1.7.0.75.x86_64
配置環(huán)境變量
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
讓修改生效
source /etc/profile
如果javac無效
yum install java-devel
