首先是前戏，推荐一个远程工具Xshell和Xftp搭配使用，以下是Xshell的官网

1.openjdk

How to download and install prebuilt OpenJDK packages
JDK 8
Debian, Ubuntu, etc.
On the command line, type:
$ sudo apt-get install openjdk-8-jre
The openjdk-8-jre package contains just the Java Runtime Environment. If you want to develop Java programs then please install the openjdk-8-jdk package.
Fedora, Oracle Linux, Red Hat Enterprise Linux, etc.
On the command line, type:
$ su -c “yum install java-1.8.0-openjdk”
The java-1.8.0-openjdk package contains just the Java Runtime Environment. If you want to develop Java programs then install the java-1.8.0-openjdk-devel package.

以上说了不同系统的安装方式，还指出命令只是安装了JRE，如果你需要开发应用程序，还需要另外安装（已经用加粗标识），想安装其它版本详情看openjdk官网介绍
http://openjdk.java.net/install/

[root@VM_207_229_centos ~]# java -version
openjdk version "1.8.0_71"
OpenJDK Runtime Environment (build 1.8.0_71-b15)
OpenJDK 64-Bit Server VM (build 25.71-b15, mixed mode)

2.tomcat

# cd /usr/local
# wget https://mirrors.tuna.tsinghua.edu.cn/apache/tomcat/tomcat-8/v8.0.36/bin/apache-tomcat-8.0.36.tar.gz
# tar xzf apache-tomcat-8.0.36.tar.gz
# mv apache-tomcat-8.0.36 tomcat
# ls
apache-tomcat-8.0.36.tar.gz  etc    include  lib64    logs    sa    share  tomcat   bin   games  lib   libexec  qcloud  sbin  src

个人习惯把tomcat放在/user/local下，下载后解压，再更名为tomcat
想要其它版本的话……在以下地址找好路径下载
https://mirrors.tuna.tsinghua.edu.cn/apache/tomcat/

修改配置文件conf/server.xml改为监听80端口，默认编码utf-8，并开启gzip压缩

<Connector port="80" protocol="HTTP/1.1"
               connectionTimeout="20000"
               redirectPort="8443" executor="tomcatThreadPool" URIEncoding="utf-8"   
               compression="on"   
               compressionMinSize="50" noCompressionUserAgents="gozilla, traviata"   
               compressableMimeType="text/html,text/xml,text/javascript,text/css,text/plain" />
    <!-- A "Connector" using the shared thread pool-->

启动tomcat，在浏览器输入ip地址访问，看到tomcat小猫页面就行了。CentOS7开放80端口，Centos 7使用firewalld代替了原来的iptables。

<!-- 启动防火墙 -->
# systemctl start  firewalld
<!-- 开启80端口，出现success表明添加成功 -->
# firewall-cmd --zone=public --add-port=80/tcp --permanent
<!-- 重启防火墙 -->
# systemctl restart firewalld.service
<!-- 检查端口 -->
# firewall-cmd --permanent --zone=public --list-ports
<!-- 自启动防火墙 -->
#systemctl enable firewalld

还有更改默认访问地址，不想见到tomcat小猫（此步骤看个人需要）

<Engine name="Catalina" defaultHost="www.caihongwen.cn">

     <Realm className="org.apache.catalina.realm.LockOutRealm">
       <Realm className="org.apache.catalina.realm.UserDatabaseRealm"
               resourceName="UserDatabase"/>
      </Realm>

      <Host name="www.caihongwen.cn"  appBase="webapps"
            unpackWARs="true" autoDeploy="true">
        <Context docBase="blog" path="" debug="0"  reloadable="true"/>
               <!-- Access log processes all example.
             Documentation at: /docs/config/valve.html
             Note: The pattern used is equivalent to using pattern="common" -->
        <Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs"
               prefix="localhost_access_log" suffix=".txt"
               pattern="%h %l %u %t "%r" %s %b" />

      </Host>
    </Engine>

请在意Host之间添加了一段代码

<Context docBase="blog" path="" debug="0"  reloadable="true"/>

这个blog是放在webapps的项目war包名，通过ip或域名直接进入博客，不会出现tomcat小猫管理页面，第一次启动tomcat稍慢，新增加的war包需要重启一次才能起效。还有一个要点是对外开启80端口。

3.mysql

使用RPM包进行安装，这种安装进程会自动完成系统的相关配置，比较方便。
另外有.tar.gz的压缩文件安装方式，推荐一个博客的介绍。

卸载原有MySQL或者Mariadb安装程序
1、CentOs7版本默认情况下安装了mariadb-libs，必须先卸载才可以继续安装MySql。
a) 查找以前是否安装mariadb-libs

# rpm -qa | grep -i mariadb-libs

b)卸载已经安装的mariadb-libs

# yum remove mariadb-libs-5.5.44-2.el7.centos.x86_64

2、查找以前是否安装MySQL

# rpm -qa | grep -i mysql

有的话，也删除

安装MySQL

# wget http://dev.mysql.com/get/mysql-community-release-el7-5.noarch.rpm
# rpm -ivh mysql-community-release-el7-5.noarch.rpm
# yum install mysql-community-server

成功安装之后重启mysql服务

# service mysqld restart

初次安装mysql是root账户是没有密码的，设置密码的方法

# mysql -uroot
mysql> set password for 'root'@'localhost' = password('mypasswd');

远程授权连接mysql

mysql> GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY 'mypasswd' WITH GRANT OPTION;
FLUSH   PRIVILEGES;

修改mysql默认编码

# vim /etc/my.cnf

作出以下修改

[client]
default-character-set=utf8
[mysqld]
character_set_server=utf8

然后重启mysql

# service mysqld restart
# mysql -uroot -p
mysql> show variables like 'character%';
+--------------------------+----------------------------+
| Variable_name            | Value                      |
+--------------------------+----------------------------+
| character_set_client     | utf8                       |
| character_set_connection | utf8                       |
| character_set_database   | utf8                       |
| character_set_filesystem | binary                     |
| character_set_results    | utf8                       |
| character_set_server     | utf8                       |
| character_set_system     | utf8                       |
| character_sets_dir       | /usr/share/mysql/charsets/ |
+--------------------------+----------------------------+
8 rows in set (0.00 sec)

mysql> show variables like 'collation%';
+----------------------+-----------------+
| Variable_name        | Value           |
+----------------------+-----------------+
| collation_connection | utf8_general_ci |
| collation_database   | utf8_general_ci |
| collation_server     | utf8_general_ci |
+----------------------+-----------------+
3 rows in set (0.00 sec)
