阿里云云服务器Centos7部署JDK8+Nginx+Tomcat8+Mysql5.7

sudo yum -y install wget

1.JDK8

1.1 下载JDK1.8，wget http://download.oracle.com/otn/java/jdk/8u102-b14/jdk-8u102-linux-x64.rpm,嫌弃阿里云速度慢，可以自己本地下载下来了再传到阿里云上。
1.2 rpm -ivh jdk-8u102-linux-x64.rpm 等待指令执行完毕

1.3 执行 java -version查看是否安装好

2.Nginx

2.1 下载Nginx wget http://nginx.org/packages/centos/7/x86_64/RPMS/nginx-1.10.2-1.el7.ngx.x86_64.rpm
2.2 rpm -ivh nginx-1.10.2-1.el7.ngx.x86_64.rpm 等待指令执行完毕

2.3 执行 nginx 启动（nginx -s stop 停止，nginx -s reload 重启）

3.Tomcat

3.1 wget http://mirrors.hust.edu.cn/apache/tomcat/tomcat-8/v8.0.39/bin/apache-tomcat-8.0.39.tar.gz
3.2 tar -zxvf apache-tomcat-8.0.39.tar.gz

4.MySQL5.7.17

PS:为了安装这个最新版，我真的是郁闷惨了，这也怪mysql越做越大，下载越来越不方便。

4.1 磨刀，找个国内的mysql镜像，阿里云没有，在souhu找到了：http://mirrors.sohu.com/mysql/MySQL-5.7/mysql-5.7.17-1.el5.x86_64.rpm-bundle.tar，这个镜像在阿里云的速度能达到3M/s,足矣。

4.2 wget http://mirrors.sohu.com/mysql/MySQL-5.7/mysql-5.7.17-1.el5.x86_64.rpm-bundle.tar
4.3 解压：tar –xvf mysql-5.7.17-1.el5.x86_64.rpm-bundle.tar 解压出来rpm包，具体几个忘了

4.4 安装这些RPM包：

需要按顺序去安装

第一：rpm -ivh mysql-community-common-5.7.13-1.el7.x86_64.rpm

这时候有可能会遇到包冲突，错误如下：

file /usr/share/mysql/slovak/errmsg.sys from install of mysql-community-common-5.7.13-1.el7.x86_64 conflicts with file from package mariadb-libs-1:5.5.41-2.el7_0.x86_64

file /usr/share/mysql/spanish/errmsg.sys from install of mysql-community-common-5.7.13-1.el7.x86_64 conflicts with file from package mariadb-libs-1:5.5.41-2.el7_0.x86_64

file /usr/share/mysql/swedish/errmsg.sys from install of mysql-community-common-5.7.13-1.el7.x86_64 conflicts with file from package mariadb-libs-1:5.5.41-2.el7_0.x86_64

file /usr/share/mysql/ukrainian/errmsg.sys from install of mysql-community-common-5.7.13-1.el7.x86_64 conflicts with file from package mariadb-libs-1:5.5.41-2.el7_0.x86_64

file /usr/share/mysql/charsets/Index.xml from install of mysql-community-common-5.7.13-1.el7.x86_64 conflicts with file from package mariadb-libs-1:5.5.41-2.el7_0.x86_64

file /usr/share/mysql/charsets/armscii8.xml from install of mysql-community-common-5.7.13-1.el7.x86_64 conflicts with file from package mariadb-libs-1:5.5.41-2.el7_0.x86_64

这只是部分

卸载掉冲突的包：yum remove mariadb-libs-1*

卸载完了继续安装：

第一个： rpm -ivh mysql-community-common-5.7.13-1.el7.x86_64.rpm

第二个：rpm -ivh mysql-community-libs-5.7.13-1.el7.x86_64.rpm

第三个：rpm -ivh mysql-community-client-5.7.13-1.el7.x86_64.rpm

第四个：rpm -ivh mysql-community-server-5.7.13-1.el7.x86_64.rpm

最后启动mysql：

service mysqld restart

mysql

这时候又会碰到困难，没有密码进不去：

exit

vi /ect/my.cnf 的最后面加上一行：

skip-grant-tables

:wq!保存退出

重启mysql服务：service mysqld restart

然后再连接mysql就可以了

进入mysql：

use mysql；

update mysql.user set authentication_string=password('123123') where user='root'；

然后再把my.cnf里面加的那行删掉，然后再用root账号和密码进入mysql

进去之后需要重新设置root密码：

ALTER USER 'root'@'localhost' IDENTIFIED BY '密码';

这个密码必须符合密码规范

flush privileges;（使立即生效）

设置远程可以登录：

GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY '密码' WITH GRANT OPTION；

FLUSH PRIVILEGES;

然后用远程访问吧。
