部署controller-manager

在10.4.7.21和10.4.7.22服务器上

一、创建启动脚本

vi /opt/kubernetes/server/bin/kube-controller-manager.sh
#!/bin/sh
./kube-controller-manager   --cluster-cidr 172.7.0.0/16   --leader-elect true   --log-dir /data/logs/kubernetes/kube-controller-manager   --master http://127.0.0.1:8080   --service-account-private-key-file ./cert/ca-key.pem   --service-cluster-ip-range 192.168.0.0/16   --root-ca-file ./cert/ca.pem   --v 2 

二、给权限，创建目录

chmod +x /opt/kubernetes/server/bin/kube-controller-manager.sh
mkdir -p /data/logs/kubernetes/kube-controller-manager

三、创建superviso的配置

vi /etc/supervisord.d/kube-conntroller-manager.ini        // 另一台只修改红色的21==》22
[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)

启动服务查看

supervisorctl update

部署kube-scheduler

在10.4.7.21和10.4.7.22主机

一、创建脚本

vi /opt/kubernetes/server/bin/kube-scheduler.sh
#!/bin/sh
./kube-scheduler   --leader-elect    --log-dir /data/logs/kubernetes/kube-scheduler   --master http://127.0.0.1:8080 
  --v 2

二、授权限，创建目录

chmod +x  /opt/kubernetes/server/bin/kube-scheduler.sh
mkdir -p /data/logs/kubernetes/kube-scheduler

三、创建superviso的配置

vi /etc/supervisord.d/kube-scheduler.ini      // 另一台只修改红色的21==》22

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)

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)
