安装前准备

        参考官方手册安装前准备，本文将基于CentOS7.9及YashanDB Personal 23.2.3 (Linux X86)进行个人版的安装。

       另：YashanDB Personal 23.2.3最低依赖OpenSSL1.1.1l，而CentOS7.9默认的openssl版本为1.0.2k，在正式安装还需要升级openssl，可参考CentOS7.9升级OpenSSL1.1.1w

创建安装目录

        YashanDB的安装使用安装前准备阶段创建的yashan系统用户执行。

cd ~  mkdir install

安装程序准备

        将安装包上传到/home/yashan/install目录下，并解压

[yashan@yasdb1 ~]$ cd ./install/ [yashan@yasdb1 install]$ ls -la *.tar.gz -rw-rw-r--. 1 yashan yashan 183555278 Jul 29 10:18 yashandb-personal-23.2.3.100-linux-x86_64.tar.gz [yashan@yasdb1 install]$  [yashan@yasdb1 install]$ tar -zxf yashandb-personal-*.tar.gz [yashan@yasdb1 install]$ ll total 179296 drwxrwxr-x. 6 yashan yashan        70 Jul  8 05:12 admin drwxrwxr-x. 2 yashan yashan       229 Jul  8 05:12 bin drwxrwxr-x. 2 yashan yashan       199 Jul 30 10:00 conf drwxrwxr-x. 4 yashan yashan        33 Jul  8 05:12 ext -rw-rw-r--. 1 yashan yashan     10698 Jul  8 05:12 gitmoduleversion.dat drwxrwxr-x. 2 yashan yashan        42 Jul  8 05:12 include drwxrwxr-x. 3 yashan yashan        17 Jul  8 05:12 java drwxrwxr-x. 2 yashan yashan      4096 Jul  8 05:12 lib -rw-r-----. 1 yashan yashan     14989 Jul  8 05:12 LICENSE drwxrwxr-x. 3 yashan yashan        41 Jul 30 09:59 om drwxrwxr-x. 3 yashan yashan        21 Jul  8 05:12 plug-in drwxrwxr-x. 2 yashan yashan        61 Jul  8 05:12 scripts -rw-rw-r--. 1 yashan yashan 183555278 Jul 29 10:18 yashandb-personal-23.2.3.100-linux-x86_64.tar.gz [yashan@yasdb1 install]$  

生成参数文件

        执行如下yasboot package命令生成安装参数文件，ssh登录密码为创建yashan用户时指定的密码，请将--ip参数后面的值更换成安装服务端所在服务器的IP地址（使用127.0.0.1会导致客户端无法连接至服务端），执行成功后，生成host.toml文件

[yashan@yasdb1 install]$ ./bin/yasboot package se gen --cluster yashandb -u yashan -p Yasdb123 --ip 192.168.99.165 --port 22 --install-path /data/yashan/yasdb_home  --data-path /data/yashan/yasdb_data --begin-port 1688   [yashan@yasdb1 install]$ [yashan@yasdb1 install]$ ll hosts.toml -rw-------. 1 yashan yashan 462 Aug  2 21:37 hosts.toml [yashan@yasdb1 install]$ cat hosts.toml uuid = "66ad89d9b08c38dc405e90ed2b69173f" cluster = "yashandb" yas_type = "SE" secret_key = "3c5aa474550beb76" add_yasdba = true  [om]   hostid = "host0001"   [om.config]     LISTEN_ADDR = "192.168.99.165:1675"  [[host]]   hostid = "host0001"   group = "yashan"   user = "yashan"   password = "Yasdb123"   ip = "192.168.99.165"   port = 22   path = "/data/yashan/yasdb_home"   [host.yasagent]     [host.yasagent.config]       LISTEN_ADDR = "192.168.99.165:1676" [yashan@yasdb1 install]$ 

执行安装

        执行如下命令安装YashanDB数据库，如实际安装数据库版本与示例中版本不同，请将-i参数后的软件包名称更改成实际名称，安装成功后，会生产yashandb.toml文件

[yashan@yasdb1 install]$  ./bin/yasboot package install -t hosts.toml -i yashandb-personal-23.2.3.100-linux-x86_64.tar.gz checking install package... install version: yashandb 23.2.3.100 host0001 100% [====================================================================]   27s update host to yasom...  [yashan@yasdb1 install]$  [yashan@yasdb1 install]$ ll yashandb.toml -rw-------. 1 yashan yashan 775 Aug  2 21:37 yashandb.toml [yashan@yasdb1 install]$ cat yashandb.toml cluster = "yashandb" create_simple_schema = false uuid = "66ad89d9b08c38dc405e90ed2b69173f" yas_type = "SE"  [[group]]   database_role = "primary"   group_type = "db"   name = "dbg1"   [group.config]     CHARACTER_SET = "utf8"     ISARCHIVELOG = true     REDO_FILE_NUM = 4     REDO_FILE_SIZE = "128M"    [[group.node]]     data_path = "/data/yashan/yasdb_data"     hostid = "host0001"     role = 1     [group.node.config]       CGROUP_ROOT_DIR = "/sys/fs/cgroup"       LISTEN_ADDR = "192.168.99.165:1688"       REPLICATION_ADDR = "192.168.99.165:1689"       RUN_LOG_FILE_PATH = "/data/yashan/yasdb_home/yashandb/23.2.3.100/log/yashandb/db-1-1/run"       RUN_LOG_LEVEL = "INFO"       SLOW_LOG_FILE_PATH = "/data/yashan/yasdb_home/yashandb/23.2.3.100/log/yashandb/db-1-1/slow" [yashan@yasdb1 install]$ 

执行部署

        执行如下命令部署YashanDB数据库，当出现status: SUCCESS则表示部署成功。

$ ./bin/yasboot cluster deploy -t yashandb.toml ...... task completed, status: SUCCESS

环境变量配置

        执行如下命令配置环境变量，使用source命令即时生效。

$ cd /data/yashan/yasdb_home/yashandb/23.2.3.100/conf # 如~/.bashrc中已存在YashanDB相关的环境变量，将其清除  $ cat yashandb.bashrc >> ~/.bashrc $ source ~/.bashrc 

设置SYS用户密码

        为了安全考虑，初始安装后，SYS密码是需要单独设置的，不提供初始密码，使用yaspwd密码设置密码。

$ cd /data/yashan/yasdb_data/db-1-1/instance $ mv yasdb.pwd yasdb1.pwd $ yaspwd file=yasdb.pwd Enter password for SYS: 

查看数据库状态

        执行如下命令查看YashanDB数据库状态，如显示出数据库状态信息即为安装成功。

[yashan@yasdb1 install]$ yasboot cluster status -c yashandb  host_id  | node_type | nodeid | pid ---------------------------------------  host0001 | db        | 1-1:1  | 12870 ----------+-----------+--------+------- [yashan@yasdb1 install]$ 

       注意：通过yasboot安装的YashanDB默认不具备守护进行monitor相关功能，当服务器重启后，查看数据库状态会报connection refused的错误，需按顺序启动yasom，yasagent，待yasom和yasagent进程启动后，才能启动数据库。

       可参考守护进程进行安装后的环境配置，开启monitor功能。

[yashan@yasdb1 install]$ yasboot cluster status -c yashandb dial tcp 192.168.99.165:1675: connect: connection refused [yashan@yasdb1 install]$ yasboot process yasom start -c yashandb warning: watch yasom error:  monitor failed, stdout: , stderr: bash: monit: command not found  start yasom successfully [yashan@yasdb1 install]$ yasboot process yasagent start -c yashandb warning: watch yasagent error:  monitor failed, stdout: , stderr: bash: monit: command not found  start local agent successfully! [yashan@yasdb1 install]$ yasboot cluster status -c yashandb  host_id  | node_type | nodeid | pid -------------------------------------  host0001 | db        | 1-1:1  | off ----------+-----------+--------+----- [yashan@yasdb1 install]$ yasboot cluster start -c yashandb  type | uuid             | name              | hostid | index    | status  | return_code | progress | cost -----------------------------------------------------------------------------------------------------------  task | 064038ce55c353e0 | StartYasdbCluster | -      | yashandb | SUCCESS | 0           | 100      | 7 ------+------------------+-------------------+--------+----------+---------+-------------+----------+------ task completed, status: SUCCESS [yashan@yasdb1 install]$ 

使用yasql连接数据库
