一、安装jdk

1，上传jdk包至服务器，解压

tar -zxvf jdk-8u73-linux-x64.tar.gz

2，配置全局变量

mv jdk1.8.0_73 jdk8
    vi /etc/profile
    #添加以下至配置文件
    export JAVA_HOME=/home/jdk8
    export JAVA_BIN=/home/jdk8/bin
    export PATH=$PATH:$JAVA_HOME/bin
    export CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar
    export JAVA_HOME JAVA_BIN PATH CLASSPATH

3，重启配置文件，查看jdk是否配置完成

#将配置文件立即生效
    source /etc/profile
    #查看jdk是否配置成
    java -version

二、安装tomcat

1、上传包至服务器，解压

tar -zxvf apache-tomcat-8.0.33.tar.gz
    mv apache-tomcat-8.0.33 tomcat

2、启动、关闭tomat

cd /tomcat/bin
    ./startup.sh 
    ./shutdown.sh

三、安装redis

1、上传包至服务器，解压

tar -zxvf redis-5.0.7.tar.gz

2，进入解压的安装包，并且执行安装命令

#进入redis目录
    cd redis-5.0.7/
    #执行make安装
    make

3，进入src目录

#在redis安装目录中
    cd /src
    
    make install

./redis-server /home/redis-5.0.7/redis.conf

四、 安装 Nginx：

yum -y install nginx  
    # 查看 Nginx 版本
    nginx -v
    # 查看 Nginx 安装目录
    rpm -ql nginx
    # 启动 Nginx
    service nginx start

五、mysql安装

1，下载并安装mysql官方的仓库

#下载安装用的Yum仓库
    wget -i -c http://dev.mysql.com/get/mysql57-community-release-el7-10.noarch.rpm
    #安装Yum Repository
    yum -y install mysql57-community-release-el7-10.noarch.rpm
    #安装mysql服务器，耗时会比较久
    yum -y install mysql-community-server

2，MySQL数据库设置

#启动MySQL
    systemctl start  mysqld.service
    # 查看MySQL运行状态
    systemctl status mysqld.service
    #查看初始密码
    grep "password" /var/log/mysqld.log
    #进入数据库（输入初始密码）
    mysql -uroot -p
    #修改密码
    ALTER USER 'root'@'localhost' IDENTIFIED BY '新密码';
    #设置简单的密码会出现如下错误，设置复杂点的就可以了
    ERROR 1819 (HY000): Your password does not satisfy the current policy requirements

出现如下图说明是安装成功并已经在运行了![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2JhaWR1XzM4MjI2MjMz_size_16_color_FFFFFF_t_70 2][]

下面就可正常使用了
