=========openssl生成文件报错====================
ssl生成文件报错：
[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 这是由于openssl库的位置不正确造成的。 解决方法： 在root用户下执行： 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

======文件构建完成，开始执行脚本===================
// 进入临时目录 cd /home/soft/mongoCluster/ // 授权目录下sh等文件 chmod 777 *.sh // 创建目录 ./first_mkdir.sh // 惟一密钥文件复制。都是用同一个文件，并授权 // key.file 文件分别复制到相应的目录 chmod 600 /home/soft/mongodbcompose/key.file chown 999 /home/soft/mongodbcompose/key.file // 将配置文件移动到相应的目录 ./second_mv.sh // 启动容器 docker-compose up -d
添加副本集
配置服务器
连接任意一个节点 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
连接任意一个节点 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" }, ] });
分片2
连接任意一个节点 mongo --host 192.168.5.201 --port 10041
docker exec -it rs_shard_server2 bash mongo --port 27018 rs.initiate({ _id: "rs-shard2-server", members: [ { _id : 0, host : "192.168.5.201:10041" }, { _id : 1, host : "192.168.5.202:10041" }, { _id : 2, host : "192.168.5.203:10041" }, ] });
配置mongos
确保mongos服务起来之后，连接到192.168.1.125:10011执行以下命令添加分片服务器信息
docker exec -it rs_mongos_server bash // 启动副本集 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")
添加用户认证
连接任意的mongos
use admin db.createUser( { user:"root", pwd:"root123456", roles:[{role:"root",db:"admin"}] } )
验证是否创建成功
db.auth('root','root123456')
=============如果一开始就加上了密码。那就不需要下面步骤了=======================
将配置文件的用户认证全部打开 security: cd /home/soft/mongocompose/file vi mongod.conf 去掉# 注释 vi mongos.conf 重新覆盖之前的配置文件 // 停掉服务 docker-compose stop ./second_mv.sh 删除存储目录lock文件 mongod.lock find /home/soft/mongocompose/ -name mongod.lock rm -rf /home/soft/mongocompose/conf/db/mongod.lock rm -rf /home/soft/mongocompose/shard1/db/mongod.lock rm -rf /home/soft/mongocompose/shard2/db/mongod.lock rm -rf /home/soft/mongocompose/shard3/db/mongod.lock chmod 400 mongodb.key chown 999 mongodb.key // 启动服务 docker-compose start // 查看服务是否启动正常 docker ps -a | grep rs // 验证 docker exec -it rs_mongos_server mongo --port 27017 use admin db.auth('root','root123456') // 插入些许测试数据 for(var i=1;i<200;i++){db.books.insert({id:i,book_name:"PHP",book_id:"888"});} // 查询插入结果 db.books.find().count(); 能查询到数据，集群成功
