InfluxData【搭建 04】shell脚本离线安装InfluxDB及mkdir xxx/data/

为了能够快速部署，编写了离线安装配置的 shell 脚本，安装文件为influxdb-1.7.6.x86_64.rpm脚本内容如下：

#!/bin/bash 
# yum -y remove influxdb.x86_64

echo "1.安装InfluxDB..."
yum localinstall -y influxdb-1.7.6.x86_64.rpm
echo "1.安装InfluxDB完毕"

echo "2.InfluxDB配置..."
mkdir -p /home/influxdb/meta
mkdir -p /home/influxdb/data
mkdir -p /home/influxdb/wal

chown -R influxdb:influxdb /home/influxdb

sed -i "26c dir = "/home/influxdb/meta"" /etc/influxdb/influxdb.conf
sed -i "45c dir = "/home/influxdb/data"" /etc/influxdb/influxdb.conf
sed -i "48c wal-dir = "/home/influxdb/wal"" /etc/influxdb/influxdb.conf
sed -i "247c enabled = true" /etc/influxdb/influxdb.conf
echo "2.InfluxDB配置完毕"

echo "3.启动InfluxDB..."
systemctl start influxd
sleep 2
systemctl status influxd
echo "3.启动InfluxDB完毕"

echo "4.创建用户及数据库..."
influx  -execute 'create user "dsj" with password '''dsj''' with all privileges;' -format 'json' -pretty
influx  -execute 'create database "sjzt";' -format 'json' -pretty
echo "4.创建用户及数据库完毕"

echo "5.开启权限认证并重启InfluxDB..."
sed -i "259c auth-enabled = true" /etc/influxdb/influxdb.conf
systemctl restart influxd
systemctl status influxd
echo "5.开启权限认证并重启InfluxDB完毕"

echo "6.配置InfluxDB开机启动..."
cat <> /etc/rc.loal
systemctl start influxd
EOF
echo "6.配置InfluxDB开机启动完毕"

使用systemctl start influxd启动过一会儿就停止了，但是使用/usr/bin/influxd -config /etc/influxdb/influxdb.conf命令可以正常启动，

# 查看系统的日志信息
tail -f /var/log/messages

# 报错
run: open server: open tsdb store: mkdir /home/influxdb/data/_internal/_series: permission denied
# 处理
chown -R influxdb:influxdb /home/influxdb/data

# 再次启动后报错
error="mkdir /home/influxdb/wal/_internal: permission denied"

# 最终处理
chown -R influxdb:influxdb /home/influxdb

调整 1️⃣ 启动后睡眠2s保证数据库启动完成，否则创建用户或数据库会报错。

echo "3.启动InfluxDB..."
systemctl start influxd
sleep 2
systemctl status influxd
echo "3.启动InfluxDB完毕"
