报错3: swapon: command not found

【报错】

➜  be git:(master) sh bin/start_be.sh --daemon
bin/start_be.sh: line 86: swapon: command not found

---

【解决】

修改 doris/output/be/bin/start_be.sh，将 swapon 部分注释掉

# if [[ "$(swapon -s | wc -l)" -gt 1 ]]; then
#     echo "Please disable swap memory before installation."
#     exit 1
# fi

报错4: command not found: mysql → 未解决

【报错】

➜  bin git:(master) mysql -h 127.0.0.1 -P 9030 -u root
zsh: command not found: mysql

---

【解决】

下载 mysql client:

brew install mysql-client

因为与 mysql (which contains client libraries) 冲突，需要配置环境变量：

echo 'export PATH="/usr/local/opt/mysql-client/bin:$PATH"' >> ~/.zshrc
~ source ~/.zshrc

错误：

➜  bin git:(master) mysql -h 127.0.0.1 -P 9030 -u root
ERROR 2003 (HY000): Can't connect to MySQL server on '127.0.0.1:9030' (61)
