安装部署YashanDB

主机环境：CentOS 7.8.2003 Intel X86 8GB 2C 192.168.0.214

操作系统调整

ulimit -c unlimited 
echo "soft core unlimited" >> /etc/security/limits.conf
echo "hard core unlimited" >> /etc/security/limits.conf

# 设置主机DNS域名解析
hostnamectl set-hostname yanshan01
echo "192.168.0.214 yanshan01" >> /etc/hosts

# 关闭透明大页
echo 'never' > /sys/kernel/mm/transparent_hugepage/enabled
echo 'never' > /sys/kernel/mm/transparent_hugepage/defrag


# 调整交换分区，在性能与稳定性（避免OOM）之间的选择
sysctl -w vm.swappiness=5
echo "vm.swappiness=5">> /etc/sysctl.conf

# 调整自动分配本地端口范围
sysctl -w net.ipv4.ip_local_port_range='32768 60999'
echo "net.ipv4.ip_local_port_range = 32768 60999" >> /etc/sysctl.conf

# 调整进程的VMA上限
sysctl -w vm.max_map_count=2000000
echo "vm.max_map_count=2000000" >> /etc/sysctl.conf

# 使调整变量生效
sysctl -p

关闭防火墙和开机自启

systemctl stop firewalld 
systemctl disable firewalld

规划准备安装YashanDB

下载YashanDB个人版数据库

# 创建YashanDB用户
useradd yashan
passwd yashan

# 调整资源限制值
cat >> /etc/security/limits.conf << EOF
yashan  soft nofile 65536
yashan  hard nofile 65536
yashan  soft nproc 65536
yashan  hard nproc 65536
yashan  soft rss unlimited
yashan  hard rss unlimited
yashan  soft stack 8192
yashan  hard stack 8192
EOF

# 上传下载的安装包到/tmp目录，调整授权
chown yashan.yashan /tmp/yashandb-personal-23.2.3.100-linux-x86_64.tar.gz

# 切换到yashan用户操作解压安装包
su - yashan
mkdir /home/yashan/install/
cd /home/yashan/install/
mv /tmp/yashandb-personal-23.2.3.100-linux-x86_64.tar.gz .
tar xzvf yashandb-personal-23.2.3.100-linux-x86_64.tar.gz

采用命令行在服务端安装

# 执行yasboot package命令生成配置文件
./bin/yasboot package se gen --cluster yashandb -u yashan -p Test@123 --ip 192.168.0.214 --port 22 --install-path /home/yashan/yasdb_home  --data-path /home/yashan/yasdb_data --begin-port 1688

直接安装

./bin/yasboot package install -t hosts.toml -i yashandb-personal-23.2.3.100-linux-x86_64.tar.gz

如果机器内存少于4GB，可以添加 -f 强制安装跳过检查

部署数据库

./bin/yasboot cluster deploy -t yashandb.toml -d

配置环境变量

cd /home/yashan/yasdb_home/yashandb/23.2.3.100/conf/
cat yashandb.bashrc >> ~/.bashrc
source ~/.bashrc

检查安装结果

cd /home/yashan/install
# 通过yasboot工具设置数据库sys用户的密码
./bin/yasboot cluster password set -n Test#123 -c yashandb
# 查看数据库状态
./bin/yasboot cluster status -c yashandb -d -u sys -p Test#123
# 查看实例状态
./bin/yasboot sql -d sys/Test#123@192.168.0.214:1688

SELECT STATUS,VERSION,STARTUP_TIME,INSTANCE_NAME FROM V$INSTANCE;
select DATABASE_NAME,OPEN_MODE,STATUS from v$database;

实例启停：

# 关闭与开启
yasboot cluster stop -c yashandb -p Test#123
yasboot cluster start -c yashandb -p Test#123

卸载

yasboot cluster clean --cluster yashandb --purge
yasboot package uninstall --cluster yashandb

特性

O记 + 有界计算
DDL 默认自动提交
DML 默认非自动提交，退出连接时会触发隐式提交
新版本yasboot操作需要带上密码

问题记录

openssl版本不对导致安装失败

openssl version

下载1.1.1l版本安装：
https://openssl-library.org/source/

github_openssl1.1.1l

# 清理低版本openssl
yum remove openssl
yum remove openssl-devel

# 下载1.1.1版本并编译安装
wget https://openssl.org/source/old/1.1.1/openssl-1.1.1l.tar.gz
tar -xzvf openssl-1.1.1l.tar.gz
cd openssl-1.1.1l
./config --prefix=/usr/local/openssl
make  
make install

# 配置软连接检查版本
ln -s /usr/local/openssl/bin/openssl /usr/bin/openssl
ln -s /usr/local/openssl/include/openssl/ /usr/include/openssl
echo "/usr/local/openssl/lib/" >> /etc/ld.so.conf
ldconfig -v
openssl version -a
