K8S(七)——部署主控节点控制器和调度器
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
[program:kube-scheduler-7-21]
command=/opt/kubernetes/server/bin/kube-scheduler.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-scheduler/scheduler.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
检查节点的健康状态
一、创建软链接
ln -s /opt/kubernetes/server/bin/kubectl /usr/bin/kubectl
二、出现下图，即全部健康
