应用商城案例发布项目

实验需求

搭建一个gpmall应用商城系统，所使用的技术有：数据库主从+书写分离、zookeeper+Kafka、redis、

nginx部署负载均衡

主机 ip地址 服务部署
node1 192.168.100.10 zookeeper、Kafka、部署mycat
node2/db1 192.168.100.20 zookeeper、Kafka、数据库主库
node3/db2 192.168.100.30 zookeeper、Kafka、数据库从库
node4 192.168.100.40 httpd

Kafka+zookeeper之前已部署

配置环境具体示例：

四台主机已关闭防火墙与selinux

4台主机设置时钟同步：

复制代码 
[root@node1 ~]# systemctl restart chronyd
[root@node1 ~]# systemctl enable chronyd
Created symlink from /etc/systemd/system/multi-user.target.wants/chronyd.service to /usr/lib/systemd/system/chronyd.service.
[root@node1 ~]# hwclock -w

[root@db1 ~]# systemctl restart chronyd
[root@db1 ~]# systemctl enable chronyd
Created symlink from /etc/systemd/system/multi-user.target.wants/chronyd.service to /usr/lib/systemd/system/chronyd.service.
[root@db1 ~]# hwclock -w

[root@db2 ~]# systemctl restart chronyd
[root@db2 ~]# systemctl enable chronyd
Created symlink from /etc/systemd/system/multi-user.target.wants/chronyd.service to /usr/lib/systemd/system/chronyd.service.
[root@db2 ~]# hwclock -w

[root@node4 ~]# systemctl restart chronyd
[root@node4 ~]# systemctl enable chronyd
Created symlink from /etc/systemd/system/multi-user.target.wants/chronyd.service to /usr/lib/systemd/system/chronyd.service.
[root@node4 ~]# hwclock -w

node4主机配置yum仓库：

复制代码 
[root@node4 ~]# cd /etc/yum.repos.d/
[root@node4 yum.repos.d]# ls
CentOS-Base.repo  epel.repo  epel-testing.repo
[root@node4 yum.repos.d]# rm -rf *
[root@node4 yum.repos.d]# vim server.repo
[aa]
name=aa1
baseurl=file:///mnt
enabled=1
gpgcheck=0
~  
[root@node4 yum.repos.d]# mount /dev/cdrom /mnt/
mount: /dev/sr0 is write-protected, mounting read-only

安装httpd：

复制代码 
[root@node4 ~]# yum -y install httpd

传输需要的文件：

复制代码 
[root@node4 ~]# cd /var/www/html/
[root@node4 html]# ls
project4
[root@node4 html]# cd project4/
[root@node4 project4]# ls
gpmall-cluster         Mycat-server-1.6-RELEASE-20161028204710-linux.tar.gz
gpmall-cluster.tar.gz  zabbix
gpmall-repo            zookeeper-3.4.14.tar.gz
kafka_2.11-1.1.1.tgz
[root@node4 project4]# cd ..
[root@node4 html]# systemctl restart httpd
[root@node4 html]# systemctl enable httpd
Created symlink from /etc/systemd/system/multi-user.target.wants/httpd.service to /usr/lib/systemd/system/httpd.service.

配置db1、db2的/etc/hosts解析文件：

复制代码 
[root@db1 ~]# vim /etc/hosts
192.168.100.20 db1
192.168.100.30 db2
~  

[root@db2 ~]# vim /etc/hosts
192.168.100.20 db1
192.168.100.30 db2
~

db1、db2配置 yum 仓库：

db1：

复制代码 
[root@db1 ~]# cd /etc/yum.repos.d/
[root@db1 yum.repos.d]# ls
CentOS-Base.repo  CentOS-Debuginfo.repo  CentOS-Media.repo    CentOS-Vault.repo
CentOS-CR.repo    CentOS-fasttrack.repo  CentOS-Sources.repo
[root@db1 yum.repos.d]# rm -rf *
[root@db1 yum.repos.d]# vim server.repo

复制代码 
[root@db1 ~]# mysql_secure_installation 

NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MariaDB
      SERVERS IN PRODUCTION USE!  PLEASE READ EACH STEP CAREFULLY!

In order to log into MariaDB to secure it, we'll need the current
password for the root user.  If you've just installed MariaDB, and
you haven't set the root password yet, the password will be blank,
so you should just press enter here.

Enter current password for root (enter for none): 
OK, successfully used password, moving on...

Setting the root password ensures that nobody can log into the MariaDB
root user without the proper authorisation.

Set root password? [Y/n] y
New password: 
Re-enter new password: 
Password updated successfully!
Reloading privilege tables..
 ... Success!


By default, a MariaDB installation has an anonymous user, allowing anyone
to log into MariaDB without having to have a user account created for
them.  This is intended only for testing, and to make the installation
go a bit smoother.  You should remove them before moving into a
production environment.

Remove anonymous users? [Y/n] y
 ... Success!

Normally, root should only be allowed to connect from 'localhost'.  This
ensures that someone cannot guess at the root password from the network.

Disallow root login remotely? [Y/n] n
 ... skipping.

By default, MariaDB comes with a database named 'test' that anyone can
access.  This is also intended only for testing, and should be removed
before moving into a production environment.

Remove test database and access to it? [Y/n] y
 - Dropping test database...
 ... Success!
 - Removing privileges on test database...
 ... Success!

Reloading the privilege tables will ensure that all changes made so far
will take effect immediately.

Reload privilege tables now? [Y/n] y
 ... Success!

Cleaning up...

All done!  If you've completed all of the above steps, your MariaDB
installation should now be secure.

Thanks for using MariaDB!

mycat 做数据库读写分离：

复制代码

在mycat节点安装java环境------mycat是基于java的：

复制代码 
[root@node1 ~]# rpm -qa | grep java
python-javapackages-3.4.1-11.el7.noarch
tzdata-java-2018e-3.el7.noarch
javapackages-tools-3.4.1-11.el7.noarch

上传压缩包：

复制代码 
[root@node1 ~]# rz -E
rz waiting to receive.
[root@node1 ~]# tar -zxvf jdk-8u181-linux-x64.tar.gz -C /usr/local/
.....
[root@node1 ~]# cd /usr/local/
[root@node1 local]# ls
bin  etc  games  include  jdk1.8.0_181  lib  lib64  libexec  sbin  share  src
[root@node1 local]# vim /etc/profile
....
export JAVA_HOME=/usr/local/jdk1.8.0_181
export PATH=$PATH:$JAVA_HOME/bin
export CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar
~  
[root@node1 local]# source /etc/profile
[root@node1 local]# java -version
java version "1.8.0_181"
Java(TM) SE Runtime Environment (build 1.8.0_181-b13)
Java HotSpot(TM) 64-Bit Server VM (build 25.181-b13, mixed mode)

部署mycat服务，将Mycat-server-1.6-RELEASE-20161028204710-linux.tar.gz上传到mycat的/root目录下，并解压到/use/local：

复制代码 
[root@node1 ~]# rz -E
rz waiting to receive.
[root@node1 ~]# tar -xzvf Mycat-server-1.6-RELEASE-20161028204710-linux.tar.gz -C /usr/local/
.....
[root@node1 ~]# cd /usr/local/
[root@node1 local]# ls
bin  etc  games  include  jdk1.8.0_181  lib  lib64  libexec  mycat  sbin  share  src

定义环境变量：

复制代码 
[root@node1 local]# vim /etc/profile
....
export MYCAT_HOME=/usr/local/mycat
~   
[root@node1 local]# source /etc/profile

编辑mycat服务读写分离的schema.xml，设置数据库写入节点为db1，读取节点db2，注意IP要修改：

复制代码 
[root@node1 local]# cd mycat/conf/
[root@node1 conf]# ls
autopartition-long.txt       rule.xml
auto-sharding-long.txt       schema.xml
auto-sharding-rang-mod.txt   sequence_conf.properties
cacheservice.properties      sequence_db_conf.properties
ehcache.xml                  sequence_distributed_conf.properties
index_to_charset.properties  sequence_time_conf.properties
log4j2.xml                   server.xml
migrateTables.properties     sharding-by-enum.txt
myid.properties              wrapper.conf
partition-hash-int.txt       zkconf
partition-range-mod.txt      zkdownload

[root@node1 conf]# vim schema.xml 
<?xml version="1.0"?>
<!DOCTYPE mycat:schema SYSTEM "schema.dtd">
<mycat:schema xmlns:mycat="http://io.mycat/">
<schema name="USERDB" checkSQLschema="true" sqlMaxLimit="100" dataNode="dn1"></schema> 
<dataNode name="dn1" dataHost="localhost1" database="test" />  
<dataHost name="localhost1" maxCon="1000" minCon="10" balance="3" dbType="mysql" dbDriver="native" writeType="0" switchType="1"  slaveThreshold="100">  
    <heartbeat>select user()</heartbeat>
    <writeHost host="hostM1" url="192.168.100.20:3306" user="root" password="123456">
        <readHost host="hostS1" url="192.168.100.30:3306" user="root" password="123456" />
    </writeHost></dataHost>
</mycat:schema>
~

编辑mycat用户的/usr/local/mycat/conf/目录下的server.xml，修改root用户的密码123456，访问mycat的逻辑库为USERDB，注意删除后几行

复制代码 
[root@node1 conf]# vim server.xml 
删除如下5行，在文件最末尾处
        <user name="user">
                <property name="password">user</property>
                <property name="schemas">TESTDB</property>
                <property name="readOnly">true</property>
        </user>

然后需要修改一出地方-----改成USERDB：

复制代码 
        <user name="root">
                <property name="password">123456</property>
                <property name="schemas">USERDB</property>

启动mycat服务：

复制代码 
[root@node1 conf]# cd ..
[root@node1 mycat]# ls
bin  catlet  conf  lib  logs  version.txt
[root@node1 mycat]# cd bin/
[root@node1 bin]# ls
dataMigrate.sh   mycat      startup_nowrap.sh     wrapper-linux-x86-32
init_zk_data.sh  rehash.sh  wrapper-linux-ppc-64  wrapper-linux-x86-64
[root@node1 bin]# ./mycat start
Starting Mycat-server...

（查看8066、9066端口是否开启，如果有开放8066和9066端口，则表示mycat服务开启成功 mycat服务默认的数据端口是8066，而9066端口则是mycat管理端口，用于管理mycat的整个集群状态）

安装MariaDB-client客户端：

mycat：

复制代码 
[root@node1 ~]# yum -y install MariaDB-client

在本地使用数据端口登录到mysql数据中，查询和插入数据，然后使用管理端口查看读写分离效果：

复制代码 
[root@node1 ~]# mysql -h127.0.0.1 -P8066 -uroot -p123456
