1 MySQL 部署

服务器
192.168.1.12

创建 MySQL 用户、新建安装目录、授权目录

useradd mysql
passwd mysql

mkdir /mysql
chown -R mysql:mysql /mysql

切换至 MySQL 用户、下载安装包、解压、重命名目录

su - mysql
cd /mysql
wget https://cdn.mysql.com/archives/mysql-5.7/mysql-5.7.36-linux-glibc2.12-x86_64.tar.gz
tar -zxvf mysql-5.7.36-linux-glibc2.12-x86_64.tar.gz
mv mysql-5.7.36-linux-glibc2.12-x86_64  mysql

初始化 MySQL

cd /mysql/mysql
bin/mysqld --initialize-insecure --user=mysql --basedir=/mysql/mysql --datadir=/mysql/mysql/data

编辑 my.cnf 配置文件

cat > /mysql/mysql/my.cnf << EOF

socket=/mysql/mysql/mysql.sock  
default-character-set=utf8

[mysqld]

启动 MySQL

echo "LimitNOFILE=65535
LimitNPROC=65535 " >> /mysql/mysql/bin/mysqld_safe
cd /mysql/mysql
bin/mysqld_safe --defaults-file=/mysql/mysql/my.cnf  --user=mysql &

配置环境变量、登陆 MySQL 、修改 root 密码

echo "PATH=\$PATH:/mysql/mysql/bin" >> ~/.bash_profile
source ~/.bash_profile

mysql -uroot 
set password=password('j9sCpEMTxM8Zr');
grant all privileges on *.* to 'root'@'%' identified by 'j9sCpEMTxM8Zr' with grant option;
flush privileges;
exit
#创建 dataease 数据库
mysql -uroot -pj9sCpEMTxM8Zr
CREATE DATABASE `dataease` DEFAULT CHARACTER SET utf8mb4 COLLATE utf8mb4_general_ci;

编写启动脚本

cat > /mysql/start.sh <<EOF
#!/bin/bash
cd /mysql/mysql && \
bin/mysqld_safe --defaults-file=/mysql/mysql/my.cnf  --user=mysql &
sleep 5 && \
echo -e "\n"
EOF
chmod +x /mysql/start.sh

加入开机启动

exit
#退出mysql回到root用户

chmod +x /etc/rc.d/rc.local
echo "su - mysql -c \"/mysql/start.sh\"" >> /etc/rc.d/rc.local

2 Doris 部署

Doris是一个高性能的分析型数据库，分为前端（FE）和后端（BE）；
FE：主要负责用户请求的接入、查询解析规划、元数据的管理、节点管理相关工作；
BE：主要负责数据存储、查询计划的执行；

Apache Doris 官方建议生产环境的配置方案：

2.1 服务器环境

（本次演示环境）

doris-fe:
192.168.1.13

doris-be:
192.168.1.14

2.2 系统优化

echo  "* soft nofile 65536
* hard nofile 65536 " >> /etc/security/limits.conf 

swapoff -a
sed -i 's/^[^#].*swap*/#&/g' /etc/fstab 
mount -a

systemctl stop firewalld
systemctl disable firewalld

2.3 配置 JDK 环境

wget -O jdk.tgz https://download.oracle.com/otn/java/jdk/8u331-b09/165374ff4ea84ef0bbd821706e29b123/jdk-8u331-linux-x64.tar.gz?AuthParam=1659681156_5e03cd86d25a21f27920eddfa4194a76 && \

tar -zxvf jdk.tgz -C /usr/local/ && \
echo "export JAVA_HOME=/usr/local/jdk1.8.0_341/
export PATH=\$JAVA_HOME/bin:\$PATH
export CLASSPATH=.\$JAVA_HOME/lib/dt.jar:\$JAVA_HOME/lib/tools.jar" >> ~/.bash_profile && \
source ~/.bash_profile && \
java -version

2.4 部署 fe

本环境 1 个 fe 节点，以下操作在 1 个 fe 节点进行

下载 doris 安装包、解压、配置环境变量

wget https://dist.apache.org/repos/dist/release/doris/1.1/1.1.1-rc03/apache-doris-1.1.1-bin-x86.tar.gz && \
tar -zxvf apache-doris-1.1.1-bin-x86.tar.gz -C /opt/ && \
cd /opt/
mv apache-doris-1.1.1-bin-x86/ doris/
#添加doris环境变量
echo "DORIS_HOME=/opt/doris" >> ~/.bash_profile
source ~/.bash_profile

配置 fe

cp /opt/doris/fe/conf/fe.conf /opt/doris/fe/conf/fe.conf.bak

sed -i "s/8192/4096/g" /opt/doris/fe/conf/fe.conf
echo "meta_dir = \${DORIS_HOME}/doris-meta
priority_networks = 192.168.1.0/24
qe_max_connection = 65535
max_conn_per_user = 1024
sys_log_delete_age=1d
audit_log_delete_age=3d
exec_mem_limit=4294967296
tablet_create_timeout_second=30
catalog_trash_expire_second = 60
enable_batch_delete_by_default=true
max_layout_length_per_row=10000000" >> /opt/doris/fe/conf/fe.conf

启动 fe

#fe1启动：
/opt/doris/fe/bin/start_fe.sh --daemon

#查看启动日志
tail -100f /opt/doris/fe/log/fe.out
#检查端口监听
ss -lnt

添加开机启动

cat > /opt/doris/fe/start.sh << EOF
#!/bin/bash
ulimit -n 65536
source /root/.bash_profile
/opt/doris/fe/bin/start_fe.sh --daemon
EOF
chmod +x /opt/doris/fe/start.sh
echo -e "sleep 10\n/opt/doris/fe/start.sh" >> /etc/rc.d/rc.local
chmod +x /etc/rc.d/rc.local

2.5 部署 be

本环境 1 个 be 节点，以下操作在 1 个节点进行

下载 doris 安装包、解压、配置环境变量

wget https://dist.apache.org/repos/dist/release/doris/1.1/1.1.1-rc03/apache-doris-1.1.1-bin-x86.tar.gz && \
tar -zxvf apache-doris-1.1.1-bin-x86.tar.gz -C /opt/ && \
cd /opt/
mv apache-doris-1.1.1-bin-x86/ doris/
#添加doris环境变量
echo "DORIS_HOME=/opt/doris" >> ~/.bash_profile
source ~/.bash_profile

配置 be

cp /opt/doris/be/conf/be.conf /opt/doris/be/conf/be.conf.bak

echo "priority_networks = 192.168.1.0/24
storage_root_path = /disk/s1
sys_log_roll_num = 1
load_error_log_reserve_hours=1
trash_file_expire_time_sec = 60
snapshot_expire_time_sec = 60
pending_data_expire_time_sec = 60
enable_spilling = true" >> /opt/doris/be/conf/be.conf

启动 be

/opt/doris/be/bin/start_be.sh --daemon
#查看启动日志
tail -100f /opt/doris/be/log/be.out
#检查端口监听
ss -lnt

添加开机启动

cat > /opt/doris/be/start.sh << EOF
#!/bin/bash
ulimit -n 65536
source /root/.bash_profile
/opt/doris/be/bin/start_be.sh --daemon
EOF
chmod +x /opt/doris/be/start.sh
echo -e "sleep 10\n/opt/doris/be/start.sh" >> /etc/rc.d/rc.local
chmod +x /etc/rc.d/rc.local

2.6 添加 be 到 fe

通过 MySQL 服务器添加 be 节点

#登录 MySQL 服务器操作
mysql -h10.102.48.20 -P9030  -uroot

#10.102.48.2 为fe节点IP
#-P9030 为fe.conf 中的 query_port
#默认使用 root 账户，无密码登录

#10.102.48.25为be节点
#9050 为 be.conf 中的 heartbeat_service_port 
ALTER SYSTEM ADD BACKEND "192.168.1.14:9050";

SHOW PROC '/backends';
#确认 Alive 为 true

2.7 创建 DataEase 库并改密

CREATE DATABASE dataease;
SET PASSWORD FOR 'root' = PASSWORD('Password123@doris');
