1、本节架构 2、创建启动脚本 3、创建supervisor配置 4、启动服务并检查 5、检查master节点
1、本节架构
2、创建启动脚本
cat > /opt/kubernetes/server/bin/kube-controller-manager.sh <<'eof' #!/bin/sh ./kube-controller-manager \ --cluster-cidr 172.7.0.0/16 \ --leader-elect \ --log-dir /data/logs/kubernetes/kube-controller-manager \ --master http://127.0.0.1:8080 \ --service-account-private-key-file ./certs/ca-key.pem \ --service-cluster-ip-range 192.168.0.0/16 \ --root-ca-file ./certs/ca.pem \ --v 2 eof chmod +x /opt/kubernetes/server/bin/kube-controller-manager.sh mkdir -p /data/logs/kubernetes/kube-controller-manager
3、创建supervisor配置
cat > /etc/supervisord.d/kube-conntroller-manager.ini <<'eof' [program:kube-controller-manager-7-21] command=/opt/kubernetes/server/bin/kube-controller-manager.sh ; the program (relative uses PATH, can take args) numprocs=1 ; number of processes copies to start (def 1) directory=/opt/kubernetes/server/bin ; directory to cwd to before exec (def no cwd) autostart=true ; start at supervisord start (default: true) autorestart=true ; retstart at unexpected quit (default: true) startsecs=30 ; number of secs prog must stay running (def. 1) startretries=3 ; max # of serial start failures (default 3) exitcodes=0,2 ; 'expected' exit codes for process (default 0,2) stopsignal=QUIT ; signal used to kill process (default TERM) stopwaitsecs=10 ; max num secs to wait b4 SIGKILL (default 10) user=root ; setuid to this UNIX account to run the program redirect_stderr=true ; redirect proc stderr to stdout (default false) stdout_logfile=/data/logs/kubernetes/kube-controller-manager/controller.stdout.log ; stderr log path, NONE for none; default AUTO stdout_logfile_maxbytes=64MB ; max # logfile bytes b4 rotation (default 50MB) stdout_logfile_backups=4 ; # of stdout logfile backups (default 10) stdout_capture_maxbytes=1MB ; number of bytes in 'capturemode' (default 0) stdout_events_enabled=false ; emit events on stdout writes (default false) eof
4、启动服务并检查
supervisorctl update supervisorctl status etcd-server-7-22 RUNNING pid 14199, uptime 0:10:55 kube-apiserver-7-22 RUNNING pid 14198, uptime 0:10:55 kube-controller-manager-7-22 RUNNING pid 14357, uptime 0:00:38 kube-scheduler-7-22 RUNNING pid 14197, uptime 0:10:55 netstat -tulnp | grep kube-con tcp6 0 0 :::10252 :::* LISTEN 14757/./kube-contro tcp6 0 0 :::10257 :::* LISTEN 14757/./kube-contro
5、检查master节点
ln -s /opt/kubernetes/server/bin/kubectl /usr/bin/kubectl
kubectl get cs
Warning: v1 ComponentStatus is deprecated in v1.19+
