检查和配置环境
- 配置内存参数
若内核参数与参考值不一致，您可通过编辑/etc/sysctl.conf 文件修改参数，如下所示：
fs.aio-max-nr= 1048576
fs.file-max= 6815744
kernel.shmall= 2097152
kernel.shmmax= 4294967295
kernel.shmmni= 4096
kernel.sem= 250 32000 100 128
net.ipv4.ip_local_port_range= 9000 65500
net.core.rmem_default= 262144
net.core.rmem_max= 4194304
net.core.wmem_default= 262144
net.core.wmem_max= 1048576
内核参数修改完毕后，重启 Linux 系统，并输入如下命令查看内核参数的修改是否正确：
/sbin/sysctl -p
/sbin/sysctl -a
预安装工作
1 创建安装用户
如下命令创建 kingbase 用户：
useradd -m kingbase
passwd kingbase
2 安装目录
KingbaseES 默认的安装目录是/opt/Kingbase/ES/V8。如果不存在，您需要使用 root 用户先创建该目录，并赋
予 kingbase 用户对该目录的读写权限。
mkdir -p /opt/Kingbase/ES/V8
chmod o+rwx /opt/Kingbase/ES/V8
也可以自定义安装路径。如自定义安装路径为/home/kingbase/kdb，使用 kingbase 用户创建目录的命令如下：
su - kingbase
mkdir -p /home/kingbase/kdb
3 数据目录
数据目录是 KingbaseES 中存放数据文件的目录，默认是在安装目录下的 data 目录。也可以与安装目录分开单独
设置。您可以根据业务系统数据量来单独设置数据目录路径，例如将数据目录初始化在本机硬盘或者挂载在盘阵上。
您可以运行如下命令创建数据目录：
mkdir -p /opt/Kingbase/ES/V8/data
注意: 数据目录不必事先创建。安装过程中会提示指定数据目录，如果目录不存在安装程序会自动创建。
4 安装包的挂载与取消
iso 格式的安装程序包需要先挂载才能使用。挂载 iso 文件需要使用 root 用户。比如挂载的目录是 iso 文件同级
目录 KingbaseES，您可以运行如下命令进行挂载：
cd KingbaseES_V008R006C008B0014_Lin64_install.iso 所在目录
su
mount KingbaseES_V008R006C008B0014_Lin64_install.iso ./KingbaseESV8
KingbaseES 目录下可以看到 setup 目录和 setup.sh 脚本。安装完成后您可以运行如下命令取消挂载 iso 文件：
su
umount ./KingbaseESV8
此时 KingbaseES 已经和 iso 文件解除挂载关系，您在 KingbaseES 目录下不会再看到安装相关文件。
命令行安装
官网说明：https://bbs.kingbase.com.cn/docHtml?recId=d16e9a1be637c8fe4644c2c82fe16444&url=aHR0cHM6Ly9iYnMua2luZ2Jhc2UuY29tLmNuL2tpbmdiYXNlLWRvYy92OS9pbnN0YWxsLXVwZGF0YS9pbnN0YWxsLWxpbnV4L2luZGV4Lmh0bWw
启动安装程序：
命令行安装支持中文和英文的文字提示。
根据操作系统的语言设置会显示对应语言的提示信息。您可以执行如下
命令查看操作系统的语言设置：
echo $LANG
如果系统显示值包含“zh_CN”，则为中文语言，安装程序会显示中文内容。否则，您可以执行如下命令修改
语言设置为中文：
export LANG=zh_CN.UTF-8
接下来开始进行命令行安装过程。您首先进入安装程序中 setup.sh 所在目录，以 kingbase 用户执行如下命令：
sh setup.sh -i console
后续按需输入，选择即可。
设置如下初始化数据库参数:
默认端口为:54321(可自定义)
。默认账户为:system(可自定义)
密码(自定义)
默认字符集编码为:UTF8(可选 GBK、GB18030)。
默认数据库兼容模式为:ORACLE(可选 PG、MySQL)
默认大小写敏感为:是(可选否)
。默认数据块大小为:8k(可选 16k、32k)
默认加密方法为 sm4(可选 rc4)。
默认身份认证方法为 scram-sha-256(可选 scram-sm3，sm4，sm3)
项目选择上 数据库兼容模式（ PG、MySQL、ORACLE），结合项目上的情况选择，不同模式下功能不同。
- 解决缺库问题
如果安装机器操作系统缺少必要的 so 库文件，您可通过如下命令查看到有缺少 so 库文件的情况。在 ${安
装目录}/Server/bin 目录下执行：
ldd * | grep “not found”
在 ${安装目录}/Server/lib 下, 执行如下命令检查是否存在缺少的 so 库文件：
ls
若检查到 ${安装目录}/Server/lib 下存在缺少的 so 库文件，则在 安装目录 / S e r v e r / l i b 下 , 执行 e x p o r t L D L I B R A R Y P A T H = {安装目录}/Server/lib 下, 执行 export LD_LIBRARY_PATH= 安装目录/Server/lib下,执行exportLDLIBRARYPATH=LD_LIBRARY_PATH:pwd
若在 ${安装目录}/Server/lib 下, 未找到缺少的 so 库文件，请联系客服人员。
此外，完成安装 KingbaseES 软件后，可继续参考《数据库部署工具使用说明》，学习如何通过数据库部署工具
安装部署集群、启停集群服务、修改配置、查看日志。
日常运维
更新连接数：
1 使用安装 kingbase 数据库的用户，修改kingbase.conf文件，在kingbase.conf配置文件后面加入： max_connections=1500 注意：这里修改数据库的最大连接数为1500，请根据实际情况修改。
2 重启数据库生效
3 查看连接数 show max_connections
4注意事项 对于数据库使用开发版本的授权，该参数max_connections超过10无效，开发版本的授权默认是10。
对于有限制连接数的授权，该参数max_connections的值不能超过授权文件中限制的连接数。
5如果通过数据库加大连接数都没有解决，需要考虑下当前的业务并发数，以及应用的连接池是否配置了最大连接数限制。
修改数据库参数文件中参数内容
vim kingbase.conf
max_connections=1000
重启金仓数据库
cd /opt/Kingbase/ES/V8/Server/bin
./sys_ctl restart -D /opt/Kingbase/ES/V8/data/
./sys_ctl start -D /opt/Kingbase/ES/V8/data/
```
[kingbase@localhost bin]$ ./sys_ctl start -D /opt/Kingbase/ES/V8/data/

V8R6版本单机数据库出现授权到期的问题需要及时更换授权文件，下面以单机数据库替换授权为例进行演示。
-
备份数据库的数据 替换授权文件前需要对数据库进行备份，执行时确保应用与数据库断开连接，避免备份时产生新的数据，导致数据丢失。
-
上传授权文件 将 新的授权文件 上传到数据库服务器上，上传后还需要检查授权文件的版本号和安装的数据库的版本是否一致，正式授权需要比对授权文件中的mac地址与本机是否一致，临时授权则不需要。
-
找到授权文件
(1)进入数据库安装路径下找到授权文件(根据现场的安装路径进行操作)
(2)find命令找到授权文件
操作命令如下：
find / -name license.dat
将找到的license.dat文件都替换成新的license.dat文件
更新软连接的文件即可 /opt/Kingbase/ES/V8/KESRealPro/V008R006C008B0014/license.dat -
修改授权文件的名字 操作命令如下： mv license.dat license.dat.bak
-
替换新的授权文件 将新的授权文件移到旧license.dat的位置，并修改新的授权文件属主和权限，使文件名属主文件权限与旧的授权文件保持一致。
操作命令如下： mv 新licese.dat /安装路径/licese.dat
chown -R kingbase:kingbase license.dat
chmod 751 license.dat -
授权文件生效
新的授权文件替换完成后需要加载才能生效。
操作命令如下：
切换账号下 su - kingbase
cd /opt/Kingbase/ES/V8/Server/bin
./sys_ctl -D /opt/Kingbase/ES/V8/data/ reload -
查看授权文件的时间 登录数据库查看授权文件的时间是否生效。
./ksql -USYSTEM -dTEST
select get_license_validdays();（用来检查数据库授权文件到期时间的函数）
如果返回值为 -2 ，表示永久license
TEST=# select get_license_info();
get_license_info
