注意：排错仅供参考！！！都是本人遇到问题时解决方法。

问题1：harbor

环境Ubuntu 1804

报错信息

# docker login harbor.123.com
Username: admin
Password: 
Error saving credentials: error storing credentials - err: exit status 1, out: `Failed to execute child process “dbus-launch” (No such file or directory)`

解决方法：

#1.删除包
sudo apt-get remove golang-docker-credential-helpers
#2。再次登录即可
docker login harbor.123.com

问题2：haproxy

环境Ubuntu 1804

报错信息

# systemctl status haproxy
● haproxy.service - HAProxy Load Balancer
   Loaded: loaded (/lib/systemd/system/haproxy.service; enabled; vendor preset: enabled)
   Active: failed (Result: exit-code) since Mon 2021-03-06 13:36:23 CST; 8min ago

Mar 06 13:36:23 ha2 systemd[1]: Failed to start HAProxy Load Balancer.

解决方法：负载服务器上都要部署

#1.修改内核参数
vim /etc/sysctl.conf
net.ipv4.ip_nonlocal_bind = 1    <--允许非本地IP地址socket监听

#2.使内核参数生效
sysctl -p

#3.启动服务&&开机启动
systemctl restart haproxy && systemctl enable haproxy

问题3：harbor改为本地拉取镜像、因为老超时所以暂时搁置

环境Ubuntu 1804

node1110

网络插件

#拉取镜像
docker pull mirrorgooglecontainers/pause-amd64:3.1

#修改tag号
docker tag mirrorgooglecontainers/pause-amd64:3.1 harbor.123.com/baseimages/pause-amd64:3.1

#登录 账号：admin 密码：123456
docker login harbor.123.com

#上传
docker push harbor.123.com/baseimages/pause-amd64:3.1

Master101

vim ./roles/kube-node/defaults/main.yml

# 默认使用kube-proxy的 'iptables' 模式，可选 'ipvs' 模式(experimental)
PROXY_MODE: "iptables"

# 基础容器镜像
SANDBOX_IMAGE: "harbor.123.com/baseimages/pause-amd64:3.1"    <--改成内部地址
#SANDBOX_IMAGE: "mirrorgooglecontainers/pause-amd64:3.1"    <--注释掉
#SANDBOX_IMAGE: "registry.access.redhat.com/rhel7/pod-infrastructure:latest"

# Kubelet 根目录
KUBELET_ROOT_DIR: "/var/lib/kubelet"

# node节点最大pod 数
MAX_PODS: 110

修改配置

vim /etc/systemd/system/kubelet.service

  --max-pods=5000 \
#  --pod-infra-container-image=mirrorgooglecontainers/pause-amd64:3.1 \      <--注释掉
  --pod-infra-container-image=harbor.123.com/baseimages/pause-amd64:3.1 \    <--修改此行

重启服务

systemctl daemon-reload
systemctl restart kubelet

calico镜像下载地址:github.com/projectcali…

点击下载release-v3.4.4.tgz

上传后解压、打镜像

cd /opt
tar xvf release-v3.4.4.tgz
cd release-v3.4.4/images

#导入镜像1
docker load -i calico-cni.tar
#修改tag号
docker tag calico/cni:v3.4.4 harbor.123.com/baseimages/calico-cni:v3.4.4
#上传镜像
docker push harbor.123.com/baseimages/calico-cni:v3.4.4

#导入镜像2
docker load -i calico-node.tar
#修改tag号
docker tag calico/node:v3.4.4 harbor.123.com/baseimages/calico-node:v3.4.4
#上传镜像
docker push harbor.123.com/baseimages/calico-node:v3.4.4

#导入镜像3
docker load -i calico-kube-controllers.tar
#修改tag号
docker tag calico/kube-controllers:v3.4.4 harbor.123.com/baseimages/kube-controllers:v3.4.4
#上传镜像
docker push harbor.123.com/baseimages/kube-controllers:v3.4.4

此步骤不要出错、否则后期排错非常麻烦！！！

vim /etc/ansible/roles/calico/templates/calico-v3.4.yaml.j2

        - name: install-cni
        #注释掉下行后、添加新的
        #  image: calico/cni:{{ calico_ver }}
          image: harbor.123.com/baseimages/calico-cni:v3.4.4
          
        - name: calico-node
        #注释掉下行后、添加新的
        #  image: calico/node:{{ calico_ver }}
          image: harbor.123.com/baseimages/calico-node:v3.4.4
          
        - name: calico-kube-controllers
        #注释掉下行后、添加新的
        #  image: calico/kube-controllers:{{ calico_ver }}        
          image: harbor.123.com/baseimages/kube-controllers:v3.4.4

问题4：没有Redis模块

环境Ubuntu 1804

报错信息

# python3 redis_monitor.sh
Traceback (most recent call last):
  File "redis_monitor.sh", line 4, in <module>
    import redis
ModuleNotFoundError: No module named 'redis'

解决方法：使用pip安装redis

apt install python-pip -y
pip install redis

#查看版本pip 9.0.1（python 2.7）
# pip --version
pip 9.0.1 from /usr/lib/python2.7/dist-packages (python 2.7)

问题5：更改gem源

环境Ubuntu 1804

国内网站：gems.ruby-china.com/

#安装
# apt install gem && apt install ruby
#查看gem源列表
# gem source list
*** CURRENT SOURCES ***

https://rubygems.org/

#添加新的源地址并删除旧的
# gem sources --add https://gems.ruby-china.com/ --remove https://rubygems.org/

#查看gem源列表（以换成新的）
# gem source list
*** CURRENT SOURCES ***

https://gems.ruby-china.com/

问题6：MYsql初始密码查询及修改

环境CentOS 7
# cat /var/log/mysqld.log|grep 'temporary password'
2023-01-08T05:18:55.845852Z 1 [Note] A temporary password is generated for root@localhost: di*:!33jtdjM
# mysql -uroot -p
Enter password:  #输入密码'!33jtdjM'后、即可连接到MYsql

#修改密码、密码为'IT123.com'
mysql> ALTER USER 'root'@'localhost' IDENTIFIED BY 'IT123.com';

#查询MySQL中当前连接的客户数量
mysql> SHOW STATUS LIKE 'Threads_connected';
+-------------------+-------+
| Variable_name     | Value |
+-------------------+-------+
| Threads_connected | 2     |  <--连接数为2、代表2个人正在使用
+-------------------+-------+
1 row in set (0.00 sec)

问题7：缺少依赖

环境Ubuntu 1804

报错：

checking for OS
+ Linux 4.15.0-29-generic x86_64 
checking for C compiler ... not found 

./configure: error: C compiler cc is not found

1.直接使用命令安装

pcre

apt-get install libpcre3 libpcre3-dev

gcc g++

apt-get install build-essential
apt-get install libtool

zlib

apt-get install zlib1g-dev

openssl

apt-get install openssl
apt-get install libssl-dev

2.再继续nginx的安装配置

不过要在./configure 后面加上参数配置https，加了这个参数https才能找到ssl模块

./configure --prefix=/usr/local/nginx

3.再make编译make install安装就不会在make报错了

问题8：服务器：Connecting to github.com (github.com)|20.205.243.166|:443... connected.

环境CentOS 7

报错信息

# wget https://github.com/prometheus/alertmanager/releases/download/v0.25.0/alertmanager-0.25.0.linux-amd64.tar.gz
--2024-04-04 18:53:47--  https://github.com/prometheus/alertmanager/releases/download/v0.25.0/alertmanager-0.25.0.linux-amd64.tar.gz
正在解析主机 github.com (github.com)... 20.205.243.166
正在连接 github.com (github.com)|20.205.243.166|:443... 失败：拒绝连接。

解决方案检查yum源，并更新nss

yum update nss

问题9：Docker缺少依赖

环境CentOS 7

报错信息

[root@rip10 ~]# yum install --setopt=obsoletes=0 docker-ce-18.06.3.ce-3.el7 -y
已加载插件：fastestmirror, langpacks
Loading mirror speeds from cached hostfile
正在解决依赖关系
--> 正在检查事务
---> 软件包 docker-ce.x86_64.0.18.06.3.ce-3.el7 将被 安装
--> 正在处理依赖关系 container-selinux >= 2.9，它被软件包 docker-ce-18.06.3.ce-3.el7.x86_64 需要
--> 解决依赖关系完成
错误：软件包：docker-ce-18.06.3.ce-3.el7.x86_64 (docker-ce-stable)
          需要：container-selinux >= 2.9
 您可以尝试添加 --skip-broken 选项来解决该问题
 您可以尝试执行：rpm -Va --nofiles --nodigest

解决方案安装epel源与安装包

[root@rip10 ~]# wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo
[root@rip10 ~]# yum install epel-release -y
[root@rip10 ~]# yum install container-selinux -y

持续更新...
