docker基本命令

yum -y update
yum install -y docker 
service docker start 或systemctl start docker                                
service docker stop  

（若是systemctl start docker啓動不了 可使用這個命令查看下狀態systemctl status docker.service）（解決辦法以下）https://www.jianshu.com/p/e637b217e9c8

修改/etc/docker/daemon.json這個文件（就這樣粘貼複製，別多逗號）

  建立的目錄是/var/lib/docker/volumes/xx/_data 
 查看數據卷信息是 docker volume inspect data_3
 查看所有是 docker volume list

 

 

 

 

 

新篇章# 《Docker環境下的先後端分離部署與運維》課程腳本

 ## Docker虛擬機經常使用命令更多資源聯繫 1. 先更新軟件包 ```shell yum -y update ``` 2. 安裝Docker虛擬機 ```shell yum install -y docker ``` 3. 運行、重啓、關閉Docker虛擬機 ```shell service docker start service docker start service docker stop ``` 4. 搜索鏡像 ```shell docker search 鏡像名稱 ``` 5. 下載鏡像 ```shell docker pull 鏡像名稱 ``` 6. 查看鏡像和重名鏡像 ```shell docker images ``` 7. 刪除鏡像 ```shell docker rmi 鏡像名稱 ``` 8. 運行容器 ```shell docker run 啓動參數 鏡像名稱 ``` 9. 查看容器列表 ```shell docker ps -a ``` 10. 中止、掛起、恢復容器 ```shell docker stop 容器ID docker pause 容器ID docker unpase 容器ID ``` 11. 查看容器信息 ```shell docker inspect 容器ID ``` 12. 刪除容器 ```shell docker rm 容器ID ``` 13. 數據卷管理 ```shell docker volume create 數據卷名稱 #建立數據卷 docker volume rm 數據卷名稱 #刪除數據卷 docker volume inspect 數據卷名稱 #查看數據卷 ``` 14. 網絡管理 ```shell docker network ls 查看網絡信息 docker network create --subnet=網段 網絡名稱 docker network rm 網絡名稱 ``` 15. 避免VM虛擬機掛起恢復以後，Docker虛擬機斷網 ```shell vi /etc/sysctl.conf ``` 文件中添加`net.ipv4.ip_forward=1`這個配置 ​```shell #重啓網絡服務 systemctl restart network ​``` ## 安裝PXC集羣，負載均衡，雙機熱備 1. 安裝PXC鏡像 ```shell docker pull percona/percona-xtradb-cluster ``` 2. 爲PXC鏡像更名 ```shell docker tag percona/percona-xtradb-cluster pxc ``` 3. 建立net1網段 ```shell docker network create --subnet=172.18.0.0/16 net1 ``` 4. 建立5個數據卷 ```shell docker volume create --name v1 docker volume create --name v2 docker volume create --name v3 docker volume create --name v4 docker volume create --name v5 ``` 5. 建立備份數據卷（用於熱備份數據） ```shell docker volume create --name backup ``` 6. 建立5節點的PXC集羣 注意，每一個MySQL容器建立以後，由於要執行PXC的初始化和加入集羣等工做，耐心等待1分鐘左右再用客戶端鏈接MySQL。另外，必須第1個MySQL節點啓動成功，用MySQL客戶端能鏈接上以後，再去建立其餘MySQL節點。 ```shell #建立第1個MySQL節點 docker run -d -p 3306:3306 -e MYSQL_ROOT_PASSWORD=abc123456 -e CLUSTER_NAME=PXC -e XTRABACKUP_PASSWORD=abc123456 -v v1:/var/lib/mysql -v backup:/data --privileged --name=node1 --net=net1 --ip 172.18.0.2 pxc #建立第2個MySQL節點 docker run -d -p 3307:3306 -e MYSQL_ROOT_PASSWORD=abc123456 -e CLUSTER_NAME=PXC -e XTRABACKUP_PASSWORD=abc123456 -e CLUSTER_JOIN=node1 -v v2:/var/lib/mysql -v backup:/data --privileged --name=node2 --net=net1 --ip 172.18.0.3 pxc #建立第3個MySQL節點 docker run -d -p 3308:3306 -e MYSQL_ROOT_PASSWORD=abc123456 -e CLUSTER_NAME=PXC -e XTRABACKUP_PASSWORD=abc123456 -e CLUSTER_JOIN=node1 -v v3:/var/lib/mysql --privileged --name=node3 --net=net1 --ip 172.18.0.4 pxc #建立第4個MySQL節點 docker run -d -p 3309:3306 -e MYSQL_ROOT_PASSWORD=abc123456 -e CLUSTER_NAME=PXC -e XTRABACKUP_PASSWORD=abc123456 -e CLUSTER_JOIN=node1 -v v4:/var/lib/mysql --privileged --name=node4 --net=net1 --ip 172.18.0.5 pxc #建立第5個MySQL節點 docker run -d -p 3310:3306 -e MYSQL_ROOT_PASSWORD=abc123456 -e CLUSTER_NAME=PXC -e XTRABACKUP_PASSWORD=abc123456 -e CLUSTER_JOIN=node1 -v v5:/var/lib/mysql -v backup:/data --privileged --name=node5 --net=net1 --ip 172.18.0.6 pxc ``` 7. 安裝Haproxy鏡像 ```shell docker pull haproxy ``` 8. 宿主機上編寫Haproxy配置文件 ```shell vi /home/soft/haproxy.cfg ``` 配置文件以下： ```properties global #工做目錄 chroot /usr/local/etc/haproxy #日誌文件，使用rsyslog服務中local5日誌設備（/var/log/local5），等級info log 127.0.0.1 local5 info #守護進程運行 daemon defaults log global mode http #日誌格式 option httplog #日誌中不記錄負載均衡的心跳檢測記錄 option dontlognull #鏈接超時（毫秒） timeout connect 5000 #客戶端超時（毫秒） timeout client 50000 #服務器超時（毫秒） timeout server 50000 #監控界面 listen admin_stats #監控界面的訪問的IP和端口 bind 0.0.0.0:8888 #訪問協議 mode http #URI相對地址 stats uri /dbs #統計報告格式 stats realm Global\ statistics #登錄賬戶信息 stats auth admin:abc123456 #數據庫負載均衡 listen proxy-mysql #訪問的IP和端口 bind 0.0.0.0:3306 #網絡協議 mode tcp #負載均衡算法（輪詢算法） #輪詢算法：roundrobin #權重算法：static-rr #最少鏈接算法：leastconn #請求源IP算法：source balance roundrobin #日誌格式 option tcplog #在MySQL中建立一個沒有權限的haproxy用戶，密碼爲空。Haproxy使用這個帳戶對MySQL數據庫心跳檢測 option mysql-check user haproxy server MySQL_1 172.18.0.2:3306 check weight 1 maxconn 2000 server MySQL_2 172.18.0.3:3306 check weight 1 maxconn 2000 server MySQL_3 172.18.0.4:3306 check weight 1 maxconn 2000 server MySQL_4 172.18.0.5:3306 check weight 1 maxconn 2000 server MySQL_5 172.18.0.6:3306 check weight 1 maxconn 2000 #使用keepalive檢測死鏈 option tcpka ``` 9. 建立兩個Haproxy容器 ```shell #建立第1個Haproxy負載均衡服務器 docker run -it -d -p 4001:8888 -p 4002:3306 -v /home/soft/haproxy:/usr/local/etc/haproxy --name h1 --privileged --net=net1 --ip 172.18.0.7 haproxy #進入h1容器，啓動Haproxy docker exec -it h1 bash haproxy -f /usr/local/etc/haproxy/haproxy.cfg #建立第2個Haproxy負載均衡服務器 docker run -it -d -p 4003:8888 -p 4004:3306 -v /home/soft/haproxy:/usr/local/etc/haproxy --name h2 --privileged --net=net1 --ip 172.18.0.8 haproxy #進入h2容器，啓動Haproxy docker exec -it h2 bash haproxy -f /usr/local/etc/haproxy/haproxy.cfg ``` 10. Haproxy容器內安裝Keepalived，設置虛擬IP ```shell #進入h1容器 docker exec -it h1 bash #更新軟件包 apt-get update #安裝VIM apt-get install vim #安裝Keepalived apt-get install keepalived #編輯Keepalived配置文件（參考下方配置文件） vim /etc/keepalived/keepalived.conf #啓動Keepalived service keepalived start #宿主機執行ping命令 ping 172.18.0.201 ``` 配置文件內容以下： ``` vrrp_instance VI_1 { state MASTER interface eth0 virtual_router_id 51 priority 100 advert_int 1 authentication { auth_type PASS auth_pass 123456 } virtual_ipaddress { 172.18.0.201 } } ``` ```shell #進入h2容器 docker exec -it h2 bash #更新軟件包 apt-get update #安裝VIM apt-get install vim #安裝Keepalived apt-get install keepalived #編輯Keepalived配置文件 vim /etc/keepalived/keepalived.conf #啓動Keepalived service keepalived start #宿主機執行ping命令 ping 172.18.0.201 ``` 配置文件內容以下： ```shell vrrp_instance VI_1 { state MASTER interface eth0 virtual_router_id 51 priority 100 advert_int 1 authentication { auth_type PASS auth_pass 123456 } virtual_ipaddress { 172.18.0.201 } } ``` 11. 宿主機安裝Keepalived，實現雙擊熱備 ```shell #宿主機執行安裝Keepalived yum -y install keepalived #修改Keepalived配置文件 vi /etc/keepalived/keepalived.conf #啓動Keepalived service keepalived start ``` Keepalived配置文件以下： ```shell vrrp_instance VI_1 { state MASTER interface ens33 virtual_router_id 51 priority 100 advert_int 1 authentication { auth_type PASS auth_pass 1111 } virtual_ipaddress { 192.168.99.150 } } virtual_server 192.168.99.150 8888 { delay_loop 3 lb_algo rr lb_kind NAT persistence_timeout 50 protocol TCP real_server 172.18.0.201 8888 { weight 1 } } virtual_server 192.168.99.150 3306 { delay_loop 3 lb_algo rr lb_kind NAT persistence_timeout 50 protocol TCP real_server 172.18.0.201 3306 { weight 1 } } ``` 12. 熱備份數據 ```shell #進入node1容器 docker exec -it node1 bash #更新軟件包 apt-get update #安裝熱備工具 apt-get install percona-xtrabackup-24 #全量熱備 innobackupex --user=root --password=abc123456 /data/backup/full ``` 13. 冷還原數據 中止其他4個節點，並刪除節點 ```shell docker stop node2 docker stop node3 docker stop node4 docker stop node5 docker rm node2 docker rm node3 docker rm node4 docker rm node5 ``` node1容器中刪除MySQL的數據 ```shell #刪除數據 rm -rf /var/lib/mysql/* #清空事務 innobackupex --user=root --password=abc123456 --apply-back /data/backup/full/2018-04-15_05-09-07/ #還原數據 innobackupex --user=root --password=abc123456 --copy-back /data/backup/full/2018-04-15_05-09-07/ ``` 從新建立其他4個節點，組件PXC集羣 ## 安裝Redis，配置RedisCluster集羣 1. 安裝Redis鏡像 ```shell docker pull yyyyttttwwww/redis ``` 2. 建立net2網段 ```shell docker network create --subnet=172.19.0.0/16 net2 ``` 3. 建立6節點Redis容器 ```shell docker run -it -d --name r1 -p 5001:6379 --net=net2 --ip 172.19.0.2 redis bash docker run -it -d --name r2 -p 5002:6379 --net=net2 --ip 172.19.0.3 redis bash docker run -it -d --name r3 -p 5003:6379 --net=net2 --ip 172.19.0.4 redis bash docker run -it -d --name r4 -p 5004:6379 --net=net2 --ip 172.19.0.5 redis bash docker run -it -d --name r5 -p 5005:6379 --net=net2 --ip 172.19.0.6 redis bash ``` 4. 啓動6節點Redis服務器 ```shell #進入r1節點 docker exec -it r1 bash cp /home/redis/redis.conf /usr/redis/redis.conf cd /usr/redis/src ./redis-server ../redis.conf #進入r2節點 docker exec -it r2 bash cp /home/redis/redis.conf /usr/redis/redis.conf cd /usr/redis/src ./redis-server ../redis.conf #進入r3節點 docker exec -it r3 bash cp /home/redis/redis.conf /usr/redis/redis.conf cd /usr/redis/src ./redis-server ../redis.conf #進入r4節點 docker exec -it r4 bash cp /home/redis/redis.conf /usr/redis/redis.conf cd /usr/redis/src ./redis-server ../redis.conf #進入r5節點 docker exec -it r5 bash cp /home/redis/redis.conf /usr/redis/redis.conf cd /usr/redis/src ./redis-server ../redis.conf #進入r6節點 docker exec -it r6 bash cp /home/redis/redis.conf /usr/redis/redis.conf cd /usr/redis/src ./redis-server ../redis.conf ``` 5. 建立Cluster集羣 ```shell #在r1節點上執行下面的指令 cd /usr/redis/src mkdir -p ../cluster cp redis-trib.rb ../cluster/ cd ../cluster #建立Cluster集羣 ./redis-trib.rb create --replicas 1 172.19.0.2:6379 172.19.0.3:6379 172.19.0.4:6379 172.19.0.5:6379 172.19.0.6:6379 172.19.0.7:6379 ``` ## 打包部署後端項目 1. 進入人人開源後端項目，執行打包（修改配置文件，更改端口，打包三次生成三個JAR文件） ```shell mvn clean install -Dmaven.test.skip=true ``` 2. 安裝Java鏡像 ```shell docker pull java ``` 3. 建立3節點Java容器 ```shell #建立數據卷，上傳JAR文件 docker volume create j1
 
 附加經常使用命令docker volume list docker volume inspect data_3
