2226:C 20 Apr 2024 17:10:45.039 # WARNING Memory overcommit must be enabled! Without it, a background save or replication may fail under low memory condition. Being disabled, it can also cause failures without low memory condition, see https://github.com/jemalloc/jemalloc/issues/1328. To fix this issue add 'vm.overcommit_memory = 1' to /etc/sysctl.conf and then reboot or run the command 'sysctl vm.overcommit_memory=1' for this to take effect.

Redis在启动时可能会出现这样的日志：在分析这个问题之前， 首先要弄清楚什么是overcommit？ Linux操作系统对大部分申请内存的请求都回复yes， 以便能运行更多的程序。 因为申请内存后， 并不会马上使用内存， 这种技术叫做overcommit。如果Redis在启动时有上面的日志， 说明vm.overcommit_memory=0， Redis提示把它设置为1。
vm.overcommit_memory用来设置内存分配策略， 有三个可选值， 如表：可用内存代表物理内存与swap之和

image-20240420171525086

解决办法：

echo "vm.overcommit_memory=1" >> /etc/sysctl.conf
sysctl vm.overcommit_memory=1
redis-server redis.conf

再重新启动就可以查看版本和端口号了

大坑来了，之前找了两个星期都没解决的

到此，harbor安装完成，但是你在网页可能会出现不能用admin登入，会显示密码错误你需要进行下一步安装证书

原因：首先pg数据库在安装harbor时创建的admin是用sha256协议加密的

image-20240430182121148

而在我们harbor页面，我们并没有配置ssl证书，是http方式访问并没有sha256加密协议，意味着harbor再登入的时候，会出现密码错误，就是：网页登入验证===/===pg数据库验证，配置openssl证书，可以解决此问题,openssl包含sha256协议，这样就可以登入了。

OpenSSL是一个强大的加密库，广泛应用于互联网的各个角落，用于保护数据传输的安全。它实现了SSL和TLS协议，这些协议是现代网络安全的基石。

配置ssl证书

操作节点：[harbor1,harbor2]

生成ca证书

创建一个放置证书相关的目录，并使用cd进入该目录

1
2
3
4
5
6
7
8
mkdir /var/harbor/cert&& cd  /var/harbor/cert
## 1. 生成CA证书私钥
openssl genrsa -out ca.key 4096
## 2. 生成CA证书，可调整 -subj 选项来表明域名名称等信息
openssl req -x509 -new -nodes -sha512 -days 3650 \
 -subj "/C=CN/ST=Beijing/L=Beijing/O=example/OU=Personal/CN=192.168.48.100" \
 -key ca.key \
 -out ca.crt

生成服务器证书

认证证书通常包含证书请求.csr文件、签名证书.crt文件及私钥.key文件，我这里harbor配置的hostname是192.168.48.100，所以最终需要生成192.168.48.100.crt、192.168.48.100.csr、192.168.48.100.key三个文件。

  • key：证书私钥，一般利用rsa等算法生成
  • csr：证书请求文件，利用证书私钥生成证书请求文件，该文件包含了服务器和地址等信息，申请人将该文件提交给CA机构，CA机构会根据该文件所携带的私钥信息来进行签名生成证书
  • crt：证书文件

## 1. 生成私钥
openssl genrsa -out 192.168.48.100.key 4096
## 2. 生成csr文件
openssl req -sha512 -new \
    -subj "/C=CN/ST=Beijing/L=Beijing/O=example/OU=Personal/CN=192.168.48.100" \
    -key 192.168.48.100.key \
    -out 192.168.48.100.csr
## 3. 生成ssl匹配多域名文，例如既想使用域名又需要通过127.0.0.1本地地址登陆测试，可使用subjectAltName参数来进行配置
cat > v3.ext <<-EOF
authorityKeyIdentifier=keyid,issuer
basicConstraints=CA:FALSE
keyUsage = digitalSignature, nonRepudiation, keyEncipherment, dataEncipherment
extendedKeyUsage = serverAuth
subjectAltName = @alt_names

[alt_names]
DNS.1=192.168.48.100
DNS.2=127.0.0.1
IP.1=192.168.48.100
EOF
## 4. 根据v3.ext及csr文件请求生成crt证书文件
openssl x509 -req -sha512 -days 3650 \
    -extfile v3.ext \
    -CA ca.crt -CAkey ca.key -CAcreateserial \
    -in 192.168.48.100.csr \
    -out 192.168.48.100.crt

# 此时直接使用docker login登陆到harbor中，会报错，下面hostname和port是harbor的配置文件中设置的名称及端口
#以下是格式
[root@xxxx harbor]# docker login [hostname]:[port]

可能会出现以下情况
#192.168.48.100是高可用vip
[root@harbor1 ~]# docker login 192.168.48.100
Username: admin
Password:
Error response from daemon: Get "https://192.168.48.100/v2/": tls: failed to verify certificate: x509: certificate signed by unknown authority

[root@qianyios ~]# docker login 192.168.48.106:8081
Username: admin
Password:
Error response from daemon: Get "https://192.168.48.106:8081/v2/": http: server gave HTTP response to HTTPS client
[root@qianyios ~]#

# 客户端默认使用的是https协议，所以需要对docker做以下修改,在文件末尾添加insecure-registries
[root@qianyios ~]# vim /etc/docker/daemon.json
{
   ................
  "registry-mirrors": [],#无关紧要，不用看,
  "insecure-registries": [ "192.168.48.100" ],#重要加这行，别忘了如果他不是最后一行一定要在末尾加逗号
 ................
}

# 修改后，重启docker使其生效
systemctl daemon-reload
systemctl restart docker

# 利用docker info查看是否添加上
[root@qianyios ~]# docker info
