LightDB单机安装

LightDB官网：https://www.hs.net/lightdb

下载安装包：lightdb-x-13.8-22.3-7953-el7.x86_64.zip

前置准备

防火墙配置(选择一种操作)

firewall防火墙

firewall-cmd --permanent --add-port=5432/tcp
firewall-cmd --permanent --add-port=123/udp

iptables防火墙

iptables -A INPUT -p tcp --dport 5432 -j ACCEPT
iptables -A INPUT -p udp --dport 123 -j ACCEPT

直接关闭防火墙

systemctl stop firewalld.service
systemctl disable firewalld.service
systemctl stop NetworkManager.service
systemctl disable NetworkManager.service

关闭 SELINUX

sed -i "s/SELINUX=enforcing/SELINUX=disabled/g" /etc/selinux/config
setenforce 0

检查时间和时区

[root@localhost lib64]# timedatectlLocal time: 五 2023-01-06 16:06:20 CST
Universal time: 五 2023-01-06 08:06:20 UTCRTC time: 五 2023-01-06 08:06:20Time zone: Asia/Shanghai (CST, +0800)NTP enabled: yes
NTP synchronized: yes
RTC in local TZ: noDST active: n/a如果需要修改可以执行：#时区列表$ timedatectl list-timezones#设定时区$ timedatectl set-timezone Asia/Shanghai

安装依赖包

以下执行命令过多，可以创建一个bash可执行文件，统一运行(示例)
$ touch pack.sh
$ vi pack.sh
$ chmod 777 pack.sh
$ ./pack.sh# 安 装 包 通 用 运 行 依 赖 ，GUI安 装 和 命 令 行 安 装 均 需 要
yum install -y procps-ng
yum install -y coreutils
# GUI安 装 运 行 依 赖 ， 仅GUI安 装 需 要
yum install -y gtk2
yum install -y libXtst
yum install -y dejavu-fonts # 麒 麟v10sp1可 能 需 要 安 装 字 体
# 数 据 库 的 运 行 依 赖
yum install -y readline
yum install -y zlib
yum install -y libxml2
yum install -y openssl-libs
yum install -y uuid
yum install -y c-ares libpcap snappy # tshark
yum install -y ncurses-libs # iftop
yum install -y libnl3 # keepalived ipv6
yum install -y libzstd # canopy
yum install -y sysstat
yum install -y json-c
yum install -y libicu

创建 lightdb 用户并设置 sudo 免密

#创建组(lightdb)
$ groupadd lightdb
#创建用户(lightdb)
$ useradd -g lightdb -m lightdb
#设置密码
$ passwd lightdb#设置免密
#修改sudoers文件权限
$ chmod 755 /etc/sudoers
$ vi /etc/sudoers追加一行：lightdb   ALL=(ALL)      NOPASSWD: ALL
$ chmod 440 /etc/sudoers

#创建安装目录
$ mkdir -p /usr/local/lightdb
# 修改目录所属用户和组
$ chown -R lightdb:lightdb /usr/local/lightdb实例目录默认路径为：安装目录下
修改默认实例目录示例：
$ mkdir -p /data/lightdb_data
$ chown -R lightdb:lightdb /data/lightdb_data

配置操作系统内核参数

echo "kernel.shmmni=4096" >> /etc/sysctl.conf
echo "kernel.shmmax=$(expr $(getconf _PHYS_PAGES) / 2 \* $(getconf PAGE_SIZE))" \
>> /etc/sysctl.conf
echo "kernel.shmall=$(expr $(getconf _PHYS_PAGES) / 2)" >> /etc/sysctl.conf
echo "kernel.sem=500 2048000 200 4096" >> /etc/sysctl.conf
echo "fs.aio-max-nr=1048576" >> /etc/sysctl.conf
echo "fs.file-max=524288" >> /etc/sysctl.conf

echo "vm.dirty_ratio=40" >> /etc/sysctl.conf
echo "vm.dirty_expire_centisecs=500" >> /etc/sysctl.conf
echo "vm.dirty_writeback_centisecs=250" >> /etc/sysctl.conf
echo "net.core.somaxconn=2000" >> /etc/sysctl.conf
echo "net.ipv4.tcp_max_syn_backlog=2000" >> /etc/sysctl.conf
echo "net.ipv4.tcp_tw_reuse=1" >> /etc/sysctl.conf
echo "net.ipv4.tcp_syn_retries=3" >> /etc/sysctl.conf
echo "net.ipv4.tcp_retries2=5" >> /etc/sysctl.conf
echo "net.ipv4.tcp_slow_start_after_idle=0" >> /etc/sysctl.conf执行: sysctl -p

配置 limits.conf

echo "lightdb hard core unlimited" >> /etc/security/limits.conf
echo "lightdb soft core unlimited" >> /etc/security/limits.conf
echo "lightdb hard nofile 524288" >> /etc/security/limits.conf
echo "lightdb soft nofile 524288" >> /etc/security/limits.conf
echo "lightdb hard nproc 16384" >> /etc/security/limits.conf
echo "lightdb soft nproc 16384" >> /etc/security/limits.conf

切换到lightdb用户执行

$ su lightdb
$ ulimit -c
$ ulimit -n
$ ulimit -u
