最近在研究金仓数据库的读写分离集群（KingbaseRWC），看着大家有写过不少图形化部署的教程了，我打算试一下静默安装的方式，本文记录一下部署过程！
PS：看着跟 Oracle ADG 有点相似。
KingbaseES 读写分离集群（KingbaseRWC）： KingbaseES 读写分离集群通过物理复制保障企业数据的高可用性、数据保护和灾难恢复并具备读请求的负载均衡能力。相比数据守护集群，该类集群中所有备库均可对外提供查询能力，从而减轻了主库的读负载压力，可实现更高的事务吞吐率；该软件支持在多个备库间进行读负载均衡。
KingbaseRWC 读写分离集群架构：
其成员可能包括主节点（primary node）、备节点（standby node）、辅助节点（witness node）、备份节点（repo node）。
KingbaseRWC 功能特点：
官方推荐配置如下：
本文演示部署一套 1 主 1 备的 KingbaseRWC 集群。
本文演示环境：
检查操作系统版本信息：
1## 以节点一为例2[root@kesrwc01 ~]# cat /etc/os-release3NAME="Kylin Linux Advanced Server"4VERSION="V10 (Halberd)"5ID="kylin"6VERSION_ID="V10"7PRETTY_NAME="Kylin Linux Advanced Server V10 (Halberd)"8ANSI_COLOR="0;31"建议配置主机名解析：
1## 以节点一为例2[root@kesrwc01 ~]# cat<<-EOF>>/etc/hosts3192.168.6.87 kesrwc014192.168.6.88 kesrwc025EOF数据库安装均建议关闭防火墙：
1## 以节点一为例2[root@kesrwc01 ~]# systemctl stop firewalld3[root@kesrwc01 ~]# systemctl disable firewalld4Removed /etc/systemd/system/multi-user.target.wants/firewalld.service.5Removed /etc/systemd/system/dbus-org.fedoraproject.FirewallD1.service.所有节点建议关闭 SELNUX，防止造成一些不必要的问题：
1## 以节点一为例2## 这里使用 setenforce 0 临时生效3[root@kesrwc01 ~]# /usr/sbin/setenforce 04/usr/sbin/setenforce: SELinux is disabled5[root@kesrwc01 ~]# sed -i 's/SELINUX=enforcing/SELINUX=disabled/g' /etc/selinux/config6[root@kesrwc01 ~]# sestatus7SELinux status: disabled将 SELINUX 参数设置为 disabled，即 SELINUX=disabled 保存退出后，需要重新启动才能生效。
建议在所有服务器上创建 KES 产品的安装用户 kingbase，而非使用 root 身份执行安装部署：
1## 以节点一为例2[root@kesrwc01 ~]# useradd -u 2000 -d /home/kingbase -m kingbase3[root@kesrwc01 ~]# echo "kingbase:kingbase" | chpasswd4[root@kesrwc01 ~]# id kingbase5用户id=2000(kingbase) 组id=2000(kingbase) 组=2000(kingbase)如果有密码复杂性要求，不想设置密码太复杂的话，可以取消密码复杂度：
1## 以节点一为例2[root@kesrwc01 ~]# sed -i 's/^password\+[[:space:]]\+requisite[[:space:]]\+pam_pwquality.so/#&/g' /etc/pam.d/system-auth3[root@kesrwc01 ~]# sed -i 's/use_authtok$//' /etc/pam.d/system-auth为了利于数据库的日常运维、持续使用、存储扩容等，我们在安装前必须做好选项、存储目录规划。
创建安装所需目录并且授权：
1## 以节点一为例2[root@kesrwc01 ~]# mkdir -p /KingbaseES/V9 /backup /archive /install /data3[root@kesrwc01 ~]# chown -R kingbase:kingbase {/KingbaseES,/backup,/archive,/install,/data}4[root@kesrwc01 ~]# chmod -R 775 {/KingbaseES,/backup,/archive,/install,/data}为了避免在 KingbaseES 安装和使用过程中出现问题，官方建议调整系统内核参数：
注意：这里关于 shmmax 和 shmall 参数值的计算，我们可以参考 Oracle 来设置：
1# 物理内存（KB）2os_memory_total=$(awk '/MemTotal/{print $2}' /proc/meminfo)3# 获取系统页面大小，用于计算内存总量4pagesize=$(getconf PAGE_SIZE)5((shmall = (os_memory_total - 1) * 1024 / pagesize))6((shmmax = os_memory_total * 1024 - 10))7# 如果 shmall 小于 2097152，则将其设为 20971528((shmall < 2097152)) && shmall=20971529# 如果 shmmax 小于 4294967295，则将其设为 429496729510((shmmax < 4294967295)) && shmmax=4294967295复制以上命令，直接执行即可计算得出这两个参数值：
1## 以节点一为例2[root@kesrwc01 ~]# echo $shmall320971524[root@kesrwc01 ~]# echo $shmmax57008071670根据官方建议值，配置系统参数文件：

1## 以节点一为例2[root@kesrwc01 ~]# sed -i 's/#RemoveIPC=no/RemoveIPC=no/' /etc/systemd/logind.conf3[root@kesrwc01 ~]# grep RemoveIPC /etc/systemd/logind.conf4RemoveIPC=no5[root@kesrwc01 ~]# sed -i 's/#DefaultTasksAccounting=yes/DefaultTasksAccounting=no/' /etc/systemd/system.conf6[root@kesrwc01 ~]# sed -i 's/#DefaultTasksMax=80%/DefaultTasksMax= 65536/' /etc/systemd/system.conf7[root@kesrwc01 ~]# cat /etc/systemd/system.conf | grep DefaultTask8DefaultTasksAccounting=no9DefaultTasksMax= 6553610# 重新加载 systemd 守护进程并重启 systemd-logind 服务生效11[root@kesrwc01 ~]# systemctl daemon-reload12[root@kesrwc01 ~]# systemctl restart systemd-logind.serviceKES 安装对于 /tmp 目录有一定要求，至少需要 10G 空间，否则安装时会报警并使用 kingbase 用户家目录作为替代：
1Now launch installer...2正在准备进行安装3警告:/tmp 磁盘空间不足！正在尝试将 /home/kingbase 用于安装基础和 tmp dir。手动挂载 /tmp 目录空间：

1[kingbase@kesrwc01 ~]$ source ~/.bash_profile配置好环境变量之后就可以不需要到指定路径下执行命令了。
这个不是必须配置，但是建议配置，用于在系统中配置 NTP 实现时间同步。
⭐️ 配置 Linux 时间同步可以参考为之前写的文章：Linux 一键配置时钟同步全攻略
安装 KingbaseRWC 之前需要在主节点安装 KingbaseES 数据库软件。
在主节点都上传 KES 最新的安装包：
KingbaseES_V009R001C002B0014_Lin64_install.iso到 /install 目录下，直接官网下载即可！
以节点一为例：
1## 挂载 iso 文件需要使用 root 用户，安装包上传在 /install 目录，挂载到 /mnt 目录下2[root@kesrwc01 ~]# umount /mnt3[root@kesrwc01 ~]# mount -o loop /install/KingbaseES_V009R001C002B0014_Lin64_install.iso /mnt/4## 将挂载出来的安装文件拷贝到 /install 目录下5[root@kesrwc01 ~]# cp -r /mnt/* /install6## 复制完成后取消安装 iso 的挂载7[root@kesrwc01 ~]# umount /mnt8## 由于之前 root 复制的安装文件权限为 root，所以需要重新授权 kingbase 用户9[root@kesrwc01 ~]# chown -R kingbase:kingbase /install10[root@kesrwc01 ~]# chmod -R 775 /install11[root@kesrwc01 ~]# su - kingbase12[kingbase@kesrwc01 ~]$ cd /install/setup13## 修改 silent.cfg 模板文件14[kingbase@kesrwc01:/install/setup]$ cat<<-EOF>/install/setup/silent.cfg15KB_LICENSE_PATH=16CHOSEN_INSTALL_SET=Custom17CHOSEN_FEATURE_LIST=DEPLOY18USER_INSTALL_DIR=/KingbaseES/V919USER_SELECTED_DATA_FOLDER=/data20DB_PORT=5432121DB_USER=system22DB_PASS=23DB_PASS2=24ENCODING_PARAM=UTF825LOCALE_PARAM=zh_CN.UTF-826INITCUSTOM=27DATABASE_MODE_PARAM=ORACLE28CASE_SENSITIVE_PARAM=YES29BLOCK_SIZE_PARAM=8k30AUTHENTICATION_METHOD_PARAM=scram-sha-25631EOF32## 静默安装33[kingbase@kesrwc01:/install/setup]$ cd /install34[kingbase@kesrwc01:/install]$ ./setup.sh -i silent -f /install/setup/silent.cfg35Now launch installer...36 Verifying JVM...Complete.安装成功后，在 ${USER_INSTALL_DIR}/ClientTools/guitools/DeployTools/zip/ 目录下拷贝安装文件到 /install 目录下：

静默安装需要先配置 install.conf 文件：
1[kingbase@kesrwc01 install]$ vi install.conf2## 修改以下几个必要参数，具体参数请参考官方文档，根据实际情况进行修改34all_ip=(192.168.6.87 192.168.6.88)5install_dir="/KingbaseES/V9/cluster/"6zip_package="/install/db.zip"7data_directory="/data"8trusted_servers="192.168.6.254"静默安装需要配置免密，使用 root 用户执行 trust_cluster.sh 脚本即可：

1/KingbaseES/V9/cluster/kingbase/bin/sys_ctl -w -t 60 -l /KingbaseES/V9/cluster/kingbase/logfile -D /data start那这看起来不就是 data_directory 的值取错了吗？应该是取 KINGBASE_HOME 环境变量才对吧！
