=========openssl生成檔案報錯====================
ssl生成檔案報錯：
[root@localhost ~]# openssl rand -base64 741 > key.file openssl: error while loading shared libraries: libssl.so.1.1: cannot open shared object file: No such file or directory 這是由於openssl庫的位置不正確造成的。 解決方法： 在root使用者下執行： ln-s /usr/local/lib64/libssl.so.1.1 /usr/lib64/libssl.so.1.1 ln -s /usr/local/lib64/libcrypto.so.1.1 /usr/lib64/libcrypto.so.1.1
==========以下每臺都執行========================

檔案複製指令碼
路徑：vi /home/soft/mongoCluster/second_mv.sh

docker-compose 檔案

======檔案構建完成，開始執行指令碼===================
// 進入臨時目錄 cd /home/soft/mongoCluster/ // 授權目錄下sh等檔案 chmod 777 *.sh // 建立目錄 ./first_mkdir.sh // 惟一金鑰檔案複製。都是用同一個檔案，並授權 // key.file 檔案分別複製到相應的目錄 chmod 600 /home/soft/mongodbcompose/key.file chown 999 /home/soft/mongodbcompose/key.file // 將配置檔案移動到相應的目錄 ./second_mv.sh // 啟動容器 docker-compose up -d
新增副本集
配置伺服器
連線任意一個節點 mongo --host 192.168.5.201 --port 10021
docker exec -it rs_config_server bash mongo --port 27019 rs.initiate({ _id: "rs-config-server", configsvr: true, members: [ { _id : 0, host : "192.168.5.201:10021" }, { _id : 1, host : "192.168.5.202:10021" }, { _id : 2, host : "192.168.5.203:10021" }, ] });
分片1
連線任意一個節點 mongo --host 192.168.5.201 --port 10031
docker exec -it rs_shard_server1 bash mongo --port 27018 rs.initiate({ _id: "rs-shard1-server", members: [ { _id : 0, host : "192.168.5.201:10031" }, { _id : 1, host : "192.168.5.202:10031" }, { _id : 2, host : "192.168.5.203:10031" }, ] });

配置mongos
確保mongos服務起來之後，連線到192.168.1.125:10011執行以下命令新增分片伺服器資訊
docker exec -it rs_mongos_server bash // 啟動副本集 mongos -f /etc/mongod/mongos.conf --configdb rs-config-server/192.168.5.201:10021,192.168.5.202:10021,192.168.5.203:10021 mongo --port 27020 sh.addShard("rs-shard1-server/192.168.5.201:10031,192.168.5.202:10031,192.168.5.203:10031") sh.addShard("rs-shard2-server/192.168.5.201:10041,192.168.5.202:10041,192.168.5.203:10041")
新增使用者認證
連線任意的mongos
use admin db.createUser( { user:"root", pwd:"root123456", roles:[{role:"root",db:"admin"}] } )
驗證是否建立成功
db.auth('root','root123456')
