Linux部署知途云课进行测试上传查看

一键部署web网页：

注意：
本次实验由阿里云官方提供资源
由于实验所需centos版本比较低为centos6.8
所以7以上版本可能会出现报错情况自行选择即可
实验所需压缩包可以根据官网进行自取：

加载环境变量使其生效：

[root@LYX ~]# source /etc/profile

再次进入一键部署web目录下：

[root@LYX ~]# cd cnmcs-web-env-installer

先进行停止避免出现缓存启动失败：

浏览器访问IP测试tomcat网页：

导入项目数据

注意：因为实验环境已经安装好Mysql所以不需要手动编译或下载

由于默认安装的mysql数据库root没有密码，用mysqladmin命令设置数据库root用户名密码为123456，如下所示：

mysqladmin -u root password "123456"

[root@LYX ~]# mysqladmin -u root password "123456"
Warning: Using a password on the command line interface can be insecure.
[root@LYX ~]#

使用mysql命令连接数据库，如下所示：

mysql --host=127.0.0.1 --port=3306 --user=root --password=123456

[root@LYX ~]# mysql --host=127.0.0.1 --port=3306 --user=root --password=123456
Warning: Using a password on the command line interface can be insecure.

执行/root目录下数据脚本zhituyunke-db.sql，如下所示：

\. /root/zhituyunke-db.sql

mysql> \. /root/zhituyunke-db.sql
Query OK, 1 row affected (0.00 sec)

Database changed
Query OK, 0 rows affected (0.00 sec)

Query OK, 0 rows affected (0.00 sec)

该脚本执行完成后，将创建名称为“zhituyunke”数据库和项目所需的表,如下所示：

show databases;

mysql> show databases;
+--------------------+
| Database           |
+--------------------+
| information_schema |
| mysql              |
| performance_schema |
| test               |
| zhituyunke         |
+--------------------+
5 rows in set (0.00 sec)

进入“zhituyunke”数据库，使用show tables查看数据库表，如下所示：

use zhituyunke;
 
show tables ;

mysql> use zhituyunke;
Database changed
 
mysql> show tables ;
+----------------------+

使用nginx+tomcat发布WEB程序

1，创建/usr/local/chinamoocs/mooc/webapp目录，将zhituyunke-web.zip解压到该目录下，如下所示：

[root@LYX ~]# mkdir -p /usr/local/chinamoocs/mooc/webapp

[root@LYX ~]# unzip -d /usr/local/chinamoocs/mooc/webapp -o /root/zhituyunke-web.zip

2，更改nginx配置:

进入/usr/local/chinamoocs/nginx/conf，修改nginx.conf文件

将/usr/local/chinamoocs/tomcat/webapps/ROOT修改成/usr/local/chinamoocs/mooc/webapp

如下图所示：

# 进入修改第64行
[root@LYX ~]# vim /usr/local/chinamoocs/nginx/conf/nginx.conf

3，重启nginx，如下所示：

[root@LYX ~]# /usr/local/chinamoocs/nginx/sbin/nginx -s reload

4，设置tomcat，将mysql的 jdbc 驱动jar (mysql-connector-java-5.1.30-bin.jar)复制到/usr/local/chinamoocs/tomcat/lib目录下，如下所示：

[root@LYX ~]# cp /root/mysql-connector-java-5.1.30-bin.jar /usr/local/chinamoocs/tomcat/lib
[root@LYX ~]#

5，将ROOT.xml文件复制到/usr/local/chinamoocs/tomcat/conf/Catalina/localhost目录下，如下所示：

[root@LYX ~]# mkdir -p /usr/local/chinamoocs/tomcat/conf/Catalina/localhost
[root@LYX ~]#
[root@LYX ~]# cp /root/ROOT.xml  /usr/local/chinamoocs/tomcat/conf/Catalina/localhost
[root@LYX ~]#

6，修改ROOT.xml中数据库连接相关信息：

[root@LYX ~]# vim /usr/local/chinamoocs/tomcat/conf/Catalina/localhost/ROOT.xml
[root@LYX ~]#
[root@LYX ~]# 修改第29行输入刚才设置的数据库密码

7，重启tomcat，如下所示：先停止再启动

[root@LYX ~]# cd /usr/local/chinamoocs/tomcat/bin
[root@LYX bin]# ./shutdown.sh
Using CATALINA_BASE:   /usr/local/chinamoocs/tomcat
Using CATALINA_HOME:   /usr/local/chinamoocs/tomcat
Using CATALINA_TMPDIR: /usr/local/chinamoocs/tomcat/temp
Using JRE_HOME:        /usr/local/chinamoocs/java
Using CLASSPATH:       /usr/local/chinamoocs/tomcat/bin/bootstrap.jar:/usr/local/chinamoocs/tomcat/bin/tomcat-juli.jar
[root@LYX bin]# ./startup.sh
Using CATALINA_BASE:   /usr/local/chinamoocs/tomcat
Using CATALINA_HOME:   /usr/local/chinamoocs/tomcat
Using CATALINA_TMPDIR: /usr/local/chinamoocs/tomcat/temp
Using JRE_HOME:        /usr/local/chinamoocs/java
Using CLASSPATH:       /usr/local/chinamoocs/tomcat/bin/bootstrap.jar:/usr/local/chinamoocs/tomcat/bin/tomcat-juli.jar
Tomcat started.
[root@LYX bin]#

重启成功后再次访问公网IP进行验证：

账号：admin        密码：123456       数据库密码

挂载云磁盘

步骤1：文件备份

当前系统上传的文件均保存在/usr/local/chinamoocs/mooc/webapp/repositry目录下（可以在系统后台上传视频文件查看该目录），也就是和web程序一样存放在系统盘，对于扩容来说会比较麻烦，现将上传文件存储到可扩容的数据盘上，下面开始挂载云磁盘的操作。

上传测试图片：进行提交

将原/usr/local/chinamoocs/mooc/webapp/repositry目录重命名为repositrybak，如下所示：

[root@LYX ~]# mv /usr/local/chinamoocs/mooc/webapp/repositry /usr/local/chinamoocs/mooc/webapp/repositrybak

步骤2：查看当前磁盘挂载情况

输入命令fdisk  -l，查询当前系统中的数据盘，可以看到当前有未挂载的数据盘信息

[root@LYX ~]# fdisk -l

Disk /dev/vda: 42.9 GB, 42949672960 bytes

Disk /dev/vdb: 21.5 GB, 21474836480 bytes
16 heads, 63 sectors/track, 41610 cylinders
Units = cylinders of 1008 * 512 = 516096 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x00000000

[root@LYX ~]#

步骤3：对数据盘进行分区

执行fdisk  /dev/vdb对数据盘进行分区，在弹出的命令行中依次输入的参数是：

[root@LYX ~]# fdisk /dev/vdb

Device contains neither a valid DOS partition table, nor Sun, SGI or OSF disklabel
Building a new DOS disklabel with disk identifier 0x7b5fa38a.
Changes will remain in memory only, until you decide to write them.
After that, of course, the previous content won't be recoverable.

Warning: invalid flag 0x0000 of partition table 4 will be corrected by w(rite)

WARNING: DOS-compatible mode is deprecated. It's strongly recommended to
         switch off the mode (command 'c') and change display units to
         sectors (command 'u').

Command (m for help): w

[root@LYX ~]#

再次执行命令fdisk  -l，如果看到显示分区/dev/vdb1的信息,则说明数据盘分区成功

[root@LYX ~]# fdisk -l

Disk /dev/vda: 42.9 GB, 42949672960 bytes
255 heads, 63 sectors/track, 5221 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

16 heads, 63 sectors/track, 41610 cylinders

/dev/vdb1               1       41610    20971408+  83  Linux
[root@LYX ~]#

步骤4：对数据盘进行格式化

使用命令mkfs.ext3  /dev/vdb1对数据盘进行格式化，如下所示：

[root@LYX ~]# mkfs.ext3 /dev/vdb1
mke2fs 1.41.12 (17-May-2010)
Filesystem label=
OS type: Linux
Block size=4096 (log=2)
Fragment size=4096 (log=2)

Writing superblocks and filesystem accounting information: done

This filesystem will be automatically checked every 28 mounts or
180 days, whichever comes first.  Use tune2fs -c or -i to override.
[root@LYX ~]#

步骤5：创建挂载点

使用mkdir创建一个挂载点，然后使用命令mount将磁盘挂载上去，最后使用命令In映射目录，如下所示：

[root@LYX ~]# mkdir /home/work
[root@LYX ~]# mount /dev/vdb1 /home/work
[root@LYX ~]# mkdir /home/work/repositry
[root@LYX ~]# ln -s /home/work/repositry /usr/local/chinamoocs/mooc/webapp/repositry


# 进行查看发现/dev/vdb1已经挂载成功
[root@LYX ~]# df -TH
Filesystem     Type   Size  Used Avail Use% Mounted on
/dev/vda1      ext4    43G  4.0G   36G  10% /
tmpfs          tmpfs  985M     0  985M   0% /dev/shm
/dev/vdb1      ext3    22G  181M   20G   1% /home/work
[root@LYX ~]#

将/usr/local/chinamoocs/mooc/webapp/repositrybak目录下文件迁移到/usr/local/chinamoocs/mooc/webapp/repositry下，如下所示：

[root@LYX ~]# mv /usr/local/chinamoocs/mooc/webapp/repositrybak/* /usr/local/chinamoocs/mooc/webapp/repositry
[root@LYX ~]#

步骤5：验证磁盘挂载效果

在/usr/local/chinamoocs/mooc/webapp/repositry目录下可以查看到新上传的视频文件。

[root@LYX ~]# cd /usr/local/chinamoocs/mooc/webapp/repositry
[root@LYX repositry]# ll
total 8
drwxr-xr-x 4 root root 4096 Apr 21 15:54 resource
drwxr-xr-x 2 root root 4096 Apr 21 15:54 temp
[root@LYX repositry]#

[root@LYX ~]# cd /usr/local/chinamoocs/mooc/webapp/repositry/

[root@LYX ~]# cd /usr/local/chinamoocs/mooc/webapp/repositry/resource/

[root@LYX ~]# cd /usr/local/chinamoocs/mooc/webapp/repositry/resource/v/2304/21/
[root@LYX 21]# ll

[root@LYX 21]#

可以看到新上传的mp4视频文件。
