ippbx cti 应用节点部署

1. 文件准备

  • 拷贝文件 zs招商copy.tar.gz 到跳板机，
  • 从跳板机上拷贝到每个机器的/root下，
  • 解压得到 keepalived,freeswtich,a生产环境部署三个目录

zs招商copy.tar.gz

2 准备本地镜像文件

准备应用节点镜像文件

  • load freeswtich压缩文件到docker 镜像，并上传到harbor仓库：

(a) 在deploy节点，即100.67.33.10上操作：

  • 准备工作
[root@nodecti2 ~]# cd /root
[root@nodecti2 ~]# tar -xzvf zs*.tar.gz  
[root@nodecti2 ~]# ls
bin  slogs  zs????copy.tar.gz  zs招商copy
[root@nodecti2 ~]# cd zs招商copy/
[root@nodecti2 zs招商copy]# ls
a生产环境部署  freeswitch  keepalived
[root@nodecti2 zs招商copy]# cd freeswitch/
[root@nodecti2 freeswitch]# ls
freeswitch.tar.bz2  fsdeb.tar  rainny.tar.bz2
  • load freeswtich压缩文件到docker 镜像
[root@nodecti2 freeswitch]# docker load -i fsdeb.tar

b) 上传镜像到Harbor仓库

  • 浏览器打开100.67.33.9 harbor仓库（登陆置灰，也能点击登陆），打开library 项目，可以查看到一些镜像，此时不需要在界面上做任何操作。
  • 在deploy节点上执行：

3 四个node-worker节点安装和配置keepalived

a 本地安装keepalived

此处在 100.67.33.7 上执行，其它三个节点类似：

[root@nodeippbx1 ~]# cd zs招商copy/
[root@nodeippbx1 zs招商copy]# ls
a生产环境部署  freeswitch  keepalived
[root@nodeippbx1 zs招商copy]# cd keepalived/
[root@nodeippbx1 keepalived]# ls
keepalived-1.3.5-8.el7_6.x86_64.rpm  lm_sensors-libs-3.4.0-6.20160601gitf9185e5.el7.x86_64.rpm  net-snmp-agent-libs-5.7.2-37.el7.x86_64.rpm  net-snmp-libs-5.7.2-37.el7.x86_64.rpm
  • 本地安装keepalived
    与上面路径一致
[root@nodeippbx1 keepalived]# yum localinstall *.rpm -y
...
Installed:

Complete!
[root@nodeippbx1 keepalived]# 
systemctl enable keepalived.service;systemctl start keepalived.service

b 配置ippbx

注意keepavlied.conf 里面，主从的virtual_router_id 必须一致，最好不要大于255，而 router_id 必须不一样，主从的router_id，state，priority 不能一样，具体如下。

  • 100.67.33.7
 # Backup
cp /etc/keepalived/keepalived.conf /etc/keepalived/keepalived.conf.ori



vim /etc/keepalived/keepalived.conf
  ###### begin
  [root@nodeippbx1 keepalived]# cat /etc/keepalived/keepalived.conf
! Configuration File for keepalived

global_defs {
   router_id ippbx_master
}

vrrp_instance VI_1 {
    state MASTER
    interface eth0
    virtual_router_id 188
    priority 100
    advert_int 1
    authentication {
        auth_type PASS
        auth_pass 1111
    }
    virtual_ipaddress {
       100.67.33.16/23 dev eth0 label eth0:1
    }
}
###### end
  • 100.67.33.8
###### begin
[root@nodeippbx2 keepalived]# cat /etc/keepalived/keepalived.conf
! Configuration File for keepalived

global_defs {
   router_id ippbx_backup
}

vrrp_instance VI_1 {
    state BACKUP
    interface eth0
    virtual_router_id 188
    priority 20
    advert_int 1
    authentication {
        auth_type PASS
        auth_pass 1111
    }
    virtual_ipaddress {
       100.67.33.16/23 dev eth0 label eth0:1
    }
}
 ###### end
  • 补充
 两台主机分别：  systemctl  enable keepalived     && systemctl start keepalived   && ps -ef | grep keepalived
 分别查看ip:   ifconfig，会发现在主节点上有：
   eth0:1: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
        inet 100.67.33.16  netmask 255.255.254.0  broadcast 0.0.0.0
        ether fa:16:3e:dd:97:61  txqueuelen 1000  (Ethernet)
 在主节点关闭keepalived,再分别查看ip，会发现从节点出现,主节点没有此vip了：
   eth0:1: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
        inet 100.67.33.16  netmask 255.255.254.0  broadcast 0.0.0.0
        ether fa:16:3e:06:a4:f6  txqueuelen 1000  (Ethernet)

c 配置两台CTI

  • 100.67.33.9
##################begin
[root@nodecti1 keepalived]# cat keepalived.conf
! Configuration File for keepalived

global_defs {
   router_id cti_master
}

vrrp_instance VI_1 {
    state MASTER
    interface eth0
    virtual_router_id 189
    priority 100
    advert_int 1
    authentication {
        auth_type PASS
        auth_pass 2222
    }
    virtual_ipaddress {
       100.67.33.17/23 dev eth0 label eth0:1
    }
}
##################end
  • 100.67.33.10
 ##################begin
 [root@nodecti2 keepalived]# cat /etc/keepalived/keepalived.conf
global_defs {
   router_id cti_backup
}

vrrp_instance VI_1 {
    state BACKUP
    interface eth0
    virtual_router_id 189
    priority 20
    advert_int 1
    authentication {
        auth_type PASS
        auth_pass 2222
    }
    virtual_ipaddress {
       100.67.33.17/23 dev eth0 label eth0:1
    }
}

d 测试Keepalived

两台节点分别执行：

[root@nodecti1 keepalived]# systemctl enable keepalived
[root@nodecti1 keepalived]# systemctl start keepalived 
[root@nodecti1 keepalived]# ps -ef | grep keep
root      1780     1  0 Jan29 ttyS0    00:00:00 /sbin/agetty --keep-baud 115200 38400 9600 ttyS0 vt220
root     16941     1  0 19:20 ?        00:00:00 /usr/sbin/keepalived -D
root     16942 16941  0 19:20 ?        00:00:00 /usr/sbin/keepalived -D
root     16943 16941  0 19:20 ?        00:00:00 /usr/sbin/keepalived -D
root     18826  4506  0 19:22 pts/1    00:00:00 grep --color=auto keep

[root@nodecti1 keepalived]# ifconfig | grep eth0   ## 在主节点能查到两个ip，从节点只有一个，当主节点停止keepalived服务后，从节点多了vip
eth0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
eth0:1: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
[root@nodecti1 keepalived]# ifconfig | grep 67
        inet 100.67.33.9  netmask 255.255.254.0  broadcast 100.67.33.255

4 配置fs app 的yaml文件

a 本地安装bzip2 包并解压文件

  • rpm包准备
    需要从外拷贝bzip2-1.0.6-13.el7.x86_64.rpm 到deploy机器，并 yum localinstall ./bzip2-1.0.6-13.el7.x86_64.rpm

  • 本地安装安装bzip2

yum localinstall ./bzip2-1.0.6-13.el7.x86_64.rpm
  • 解压rainny.tar.bz2与freeswitch.tar.bz2
[root@nodecti2 freeswitch]# yum localinstall ./bzip2-1.0.6-13.el7.x86_64.rpm
[root@nodecti2 freeswitch]# pwd
/root/zs招商copy/freeswitch
[root@nodecti2 freeswitch]# ls
freeswitch.tar.bz2  fsdeb.tar  rainny.tar.bz2    
[root@nodecti2 freeswitch]# tar -xjvf rainny.tar.bz2  
[root@nodecti2 freeswitch]# tar -xjvf freeswitch.tar.bz2
[root@nodecti2 freeswitch]# ls
freeswitch  freeswitch.tar.bz2  fsdeb.tar  rainny  rainny.tar.bz2

b 准备映射到pod内的host目录

  • 为四个node_worker节点打标签
    运行节点：在master上执行：
[root@master1 ~]# kubectl get nodes -o wide
NAME         STATUS    ROLES     AGE       VERSION
master1      Ready     master    1d        v1.11.8
master2      Ready     master    1d        v1.11.8
master3      Ready     master    1d        v1.11.8
nodecti1     Ready     <none>    1d        v1.11.8
nodecti2     Ready     <none>    1d        v1.11.8
nodeippbx1   Ready     <none>    1d        v1.11.8
nodeippbx2   Ready     <none>    1d        v1.11.8
[root@master1 ~]# kubectl label node nodeippbx1 pcc/ippbx=true
[root@master1 ~]# kubectl label node nodeippbx2 pcc/ippbx=true
[root@master1 ~]# kubectl label node nodecti1 pcc/cti=true
[root@master1 ~]# kubectl label node nodecti2 pcc/cti=true
  • [?]配置免密传输
免密登陆
  • 准备映射到pod内的host目录：
    将上面解压的rainny目录，拷贝到四个工作节点的 /data (单独逻辑卷)目录下：
 scp -r rainny 100.67.33.7:/data
 scp -r rainny 100.67.33.8:/data
 scp -r rainny 100.67.33.9:/data
 scp -r rainny 100.67.33.10:/data

补充脚本

IPPBX

 cp /root/zs招商copy/freeswitch/config/rc.local-pbbxc rc.local

c 修改配置文件 pcc.yaml

  • Path: /data
  • command

Keepalived config

code

运维

常用的命令

  • 搜索文件
  252  [2019-03-27 11:43:11] find -name "*.yml"
  253  [2019-03-27 11:44:24] find -name "*.yaml"
Action Command Remarks
kubectl logs -f pod/ippbx-0 -n pcc
kubectl describe pod/ippbx-0 -n pcc
kubectl get nodes,pod -n pcc
restart systemctl start keepalived
check process ` ps -ef grep keepalived `
