SinoDB 安装与手动创建实例
安装环境说明
SinoDB 是一款典型的事务型数据库，类似于Oracle，MySQL等。这款数据库对安装环境要求不高，完全可以在虚拟机上安装和学习。
操作系统的安装
我安装的操作系统是CentOS 7.3。在安装时，选择的是开发和创新工作站，安装后，大概有1500多个rpm包。安装后，关闭了SELinux和防火墙。在使用这样的操作系统安装时，可以非常顺利的进行 SinoDB 的安装。对于采用最小化安装操作系统的同学，可能需要手动安装jre环境和unzip命令：
yum install -y java-1.8. 0-openjdk.x86_ 64
yum install -y unzip-6.0-16.e17 .x86_ 64
使用yum安装软件包时，需要做一些基本的配置，具体方法可以自行在网上查看。
手动安装成功后，可以通过下面的命令确认。
[root@vm84145 ~]# java -version
openjdk version "1.8.0_181"
OpenJDK Runtime Environment (build 1.8.0_181-b13)
OpenJDK 64-Bit Server VM (build 25.181-b13, mixed mode)
[root@vm84145 ~]# which unzip
/usr/bin/unzip
[root@vm84145 ~]#
至此，我们就准备好了安装 SinoDB 的软件环境。其实说这句话，我还是比较心虚的。SinoDB 需要下面列出的rpm包，不过这些rpm在使用最小化安装操作系统时，已经全部安装过了。喜欢使用Docker的同学，需要认真检查一下，这些rpm包是不是真的已经安装成功。
audit-libs-2.6.5-3.el7.x86_ 64
elfutils-libelf-0.166-2.e17.x86_ 64
expat-2.1.0-8.e17.x86_ 64
fontconfig-2.10. 95-10.el7.x86_ 64
freetype-2.4.11-12.el7.x86_ 64
glibc-2.17-157.e17.x86_ _64
libcap-ng-0.7.5-4.e17 .x86_ 64
1ibgcc-4.8.5-11.el7.x86_ 64
libstdc++-4.8.5-11.el7.x86_ 64
libX11-1.6.3-3.el7.x86_ _64
libXau-1.0.8-2.1.e17.x86_ 64
libxcb-1.11-4.e17.x86_ _64
libXext-1.3.3-3.e17.x86_ _64
libXrender-0.9.8-2.1.e17.x86_ 64
ncurses-libs-5.9-13. 20130511.e17.x86_ 64
nss-softokn-freebl-3.16.2.3-14.4.el7.x86_ _64
pam-1.1.8-18.el7.x86_ 64
readline-6.2-9.e17.x86_ 64
zlib-1.2.7-17.el7.x86_ 64
unzip-6.0-16.e17 .x86_ 64
java-1.8.0-openjdk. x86_ _64
安装程序需要的命令有很多，都是一些基础的Linux命令，如rm，grep，gzip，cut，md5sum，echo，awk，ls，tar，tr，eval，expr等，我还没有时间认真的统计一下。不过这些命令在操作系统安装时，多数已经安装成功（除了unzip），大家在安装时，基本不会因为这些命令不存在而导致安装失败。
硬件环境检查
SinoDB 的数据库组件安装完成后，大约有500M，但存储物理日志，逻辑日志，智能大对象，临时数据和业务数据都需要使用磁盘存储空间，建议至少有10G以上的磁盘空闲空间。当希望练习一些需要数据量较大的操作时，这一点尤为重要。
我演示用的安装环境，是一台安装了CentOS Linux release 7.6.1810 (Core) 操作系统的VMware虚拟机，4核CPU，8G内存，千兆网卡，预分配了160G的磁盘空间。
1.查看服务器内存
[root@vm84145 ~]# free -m

[root@vm84145 ~]#
2.查看可用磁盘空间
[root@vm84145 ~]# df -h

4.查看操作系统版本
[root@vm84145 ~]# cat /etc/redhat-release
CentOS Linux release 7.6.1810 (Core)
[root@vm84145 ~]#
安装前的准备
创建用户和组
SinoDB安装，需要一个名称为informix的用户和组，做为数据库的超级管理员。
[root@vm84145 ~]# groupadd informix
[root@vm84145 ~]# useradd -g informix -d /home/informix -s /bin/bash -m informix
[root@vm84145 ~]#
上传安装包和解压缩
可以通过ftp或其它第三方工具，将安装包上传到root用户下的一个目录中。
[root@vm84145 tmp]# ls
iif.12.10.FC8.linux-x86_64-GIT-4bcde202b.tar
[root@vm84145 tmp]#
数据库安装路径目录准备（ /home/informix/sinodb）
[root@vm84145 ~]# mkdir /home/informix/sinodb
[root@vm84145 ~]#
数据库的数据文件目录准备（ /home/informix/dbs ）
[root@vm84145 ~]# mkdir /home/informix/dbs
[root@vm84145 ~]#
修改目录文件权限
[root@vm84145 ~]# ll /home/informix/
total 0
drwxr-xr-x 2 root root 6 Feb 14 18:32 dbs
drwxr-xr-x 2 root root 6 Feb 14 18:32 sinodb
[root@vm84145 ~]# chown -Rf informix:informix /home/informix
[root@vm84145 ~]# ll /home/informix/
total 0
drwxr-xr-x 2 informix informix 6 Feb 14 18:32 dbs
drwxr-xr-x 2 informix informix 6 Feb 14 18:32 sinodb
为后续的OAT配置更新目录权限：
[root@vm84145 ~]# chmod 755 /home/informix
[root@vm84145 ~]# ll /home/informix/
total 0
drwxr-xr-x 2 informix informix 6 Feb 14 18:32 dbs
drwxr-xr-x 2 informix informix 6 Feb 14 18:32 sinodb
使用root用户将安装包接解压到sinodb目录中
[root@vm84145 ~]# tar -xvf /tmp/iif.12.10.FC8.linux-x86_64-GIT-4bcde202b.tar -C /home/informix/sinodb

安装程序开始安装工作。大概经过1分钟多一点时间，即可完成数据库程序的安装。
安装完成后，回车退出安装程序。记得在显示PRESS
至此，数据库程序安装完成。
创建数据库实例
如果你想更深入的了解 SinoDB 数据库，可以学习如果手动安装一个数据库实例。采用这样的方式可能会让你暂时遇到一点点困难，但这项技能很重要，为了掌握这个方法付出努力是值得的。理解如何手动部署实例，让我们后面学习单机多实例部署，基于共享存储的高可用集群部署和多机的同城灾备集群部署更轻松。
使用informix用户进行数据库实例的创建操作，手动创建数据库实例的步骤主要有：
1.配置环境变量
2.配置sqlhosts
3.配置onconfig
4.初始化数据库实例
5.创建数据库空间
6.将逻辑日志从根数据库空间，迁移到正式的逻辑日志空间。
7.将物理日志从根数据库空间，迁移到正式的物理日志空间。
8.根据创建的数据库空间，更新onconfig
规划数据库空间
在正式开始创建数据库实例前，我们先规划一下我们的数据库。
SinoDB 中可以创建多种类型的数据库空间
本次实验我们规划创建的数据库空间如下(注意：使用informix用户进行操作)：

通过env命令查看，配置的环境变量已经生效。
配置sqlhosts
参考环境变量中设置的$INFORMIXSERVER与$INFORMIXSQLHOSTS，生成sqlhosts的配置文件。
[informix@vm84145 ~]$ cp $INFORMIXDIR/etc/sqlhosts.std $INFORMIXSQLHOSTS
[informix@vm84145 ~]$ ls $INFORMIXSQLHOSTS
/home/informix/sinodb/etc/sqlhosts.sinodb

# Title: sqlhosts.demo
# Description: Default sqlhosts file for running demos.
#
#**************************************************************************
# The connectivity information for each database server includes four fields
# of required information and one optional field. You can also configure
# database server groups.
#
# The format for the five fields of connectivity information for a database
# server is one line in the UNIX sqlhosts file, as follows:
#
# <dbservername> <nettype> <hostname> <servicename> <options>
#
# dbservername is the name of a database server on the network.
#
# nettype is an 8-character string specifying the protocol in this format:
#
# ddiiippp
#
# where
# dd = Database product [|ol|on|dr]
# iii = Interface type [ipc|soc|tli|sql]
# ppp = Protocol [imc|nmp|shm|spx|str|tcp|ssl|mux]
#
# hostname is the name of the computer where the database server resides.
#
# servicename is a service name entry from the services file.
#
# options in the fifth field:
#
# b=<connection buffer size>
# c=<connection redirection>
# g=<group name>
# i=<group identifier>
# e=<end of group>
# m=<multiplexed connection>
# k=<keep alive setting>
# r=<client security setting>
# s=<server security setting>
# csm=<communication support module>
# cfd=<communication files directory>
#
# To create an entry for a group, put a group name in the dbservername field,
# the word group in the nettype field, a hyphen in both the hostname and the
# servicename fileds, and i=<group identifier> in the options field.
#
# For additional information on the parameters, see the IBM Informix
# Administrator's Guide.

sinodb onsoctcp 192.168.84.145 1526
sqlhosts文件配置信息的第一部分，指定了数据库实例名称，第二部分指定了通讯协议，第三部分指定了服务器监听的IP地址，第四部分指定了服务器监听的端口号。
配置onconfig
onconfig文件的配置，是手动创建实例中比较关键的步骤。我们可以复制一个标准onconfig模板内容，经过适当的修改，做为我们的onconfig。
根据环境变量配置的$ONCONFIG值，我们在$INFORMIXDIR/etc目录下，创建名称为$ONCONFIG值的文件，即配置参数文件为/home/informix/onconfig.sinodb
。
通过标准配置文件，复制数据库实例的配置文件。
[informix@vm84145 etc]$ pwd
/home/informix/sinodb/etc
[informix@vm84145 etc]$ ls onconfig.*
onconfig.std
[informix@vm84145 etc]$ cp onconfig.std $ONCONFIG
[informix@vm84145 etc]$ ls onconfig.*
onconfig.sinodb onconfig.std
[informix@vm84145 etc]$ vi $INFORMIXDIR/etc/$ONCONFIG
数据库实例关键参数信息标准文件默认值
ROOTPATH /home/informix/dbs/rootdbs
ROOTSIZE 2048000 #测试环境分配2GB空间，根据实际情况修改
DBSERVERNAME sinodb #与环境变量保持一致
TAPEDEV /dev/null
LTAPEDEV /dev/null
初始化实例
在初始化实例前，需要保证rootdbs对应的文件已经存在，并有正确的访问权限（一般为660）。在前面我们已经创建了根数据库空间rootdbs，并授权。现在我们可以通过oninit -ivy命令初始化数据库实例。

添加表空间
只有root数据库空间的实例，无法应用于生产环境的部署。我们可以根据生产环境实际要求，创建适合自己需要的多个数据库空间。SinoDB 提供了onspaces命令，用于数据库空间的创建。

我们可以使用onparams命令，将逻辑日志和物理日志进行迁移，该命令的语法如下：
[informix@vm84145 ~]$ onparams --
Usage: onparams { -a -d <DBspace> [-s <size>] [-i] } |
{ -b -g <pagesize> [-n <number of buffers>]
[-r <number of LRUs>] [-x <maxdirty>] [-m <mindirty>] } |
{ -d -l <log file number> [-y] } |
{ -p -s <size> [-d <DBspace>] [-y] }
-a - Add a logical log file
-b - Add a buffer pool
-i - Insert after current log
-d - Drop a logical log file
-p - Change physical log size and location
-y - Automatically responds "yes" to all prompts
[informix@vm84145 ~]$
使用下面的语法，进行物理日志的迁移。
onparams -p -d plogdbs -s 2047890 -y

must be taken of the following spaces before an incremental archive will be
permitted for them: rootdbs plogdbs

至此，逻辑日志迁移成功。
更新onconfig文件
由于添加了临时数据库空间，迁移了物理日志和逻辑日志，需要更新配置文件中对应的参数值。
查看逻辑日志文件数量，该参数已经更新。
[informix@vm84145 ~]$ onstat -c | grep LOGFILES
# LOGFILES - The number of logical log files
LOGFILES 10
[informix@vm84145 ~]$ onstat -g cfg | grep LOGFILES
LOGFILES 10
[informix@vm84145 ~]$
查看逻辑日志大小，发现还是以前的配置值，需要更新逻辑日志文件大小。
[informix@vm84145 ~]$ onstat -c | grep LOGSIZE
# LOGSIZE - The size of each logical log, in KB
LOGSIZE 10000
[informix@vm84145 ~]$ onstat -wf LOGSIZE=204780
Unable to open input file 'LOGSIZE=204780'
[informix@vm84145 ~]$ onstat -c | grep LOGSIZE
# LOGSIZE - The size of each logical log, in KB
LOGSIZE 10000
[informix@vm84145 ~]$ onmode -wf LOGSIZE=204780
Value of LOGSIZE has been changed to 204780 kilobytes.
[informix@vm84145 ~]$ onstat -g cfg | grep LOGSIZE
LOGSIZE 204780
[informix@vm84145 ~]$
由于创建了三个临时数据库空间，需要配置数据库实例可用的临时数据库空间
[informix@vm84145 ~]$ onstat -c | grep DBSPACETEMP
# DBSPACETEMP - The list of dbspaces used to store temporary
DBSPACETEMP
[informix@vm84145 ~]$ onmode -wf DBSPACETEMP=tempdbs1,tempdbs2,tempdbs3
Value of DBSPACETEMP has been changed to tempdbs1,tempdbs2,tempdbs3.
[informix@vm84145 ~]$ onstat -c | grep DBSPACETEMP
# DBSPACETEMP - The list of dbspaces used to store temporary
DBSPACETEMP tempdbs1,tempdbs2,tempdbs3
[informix@vm84145 ~]$ onstat -g cfg | grep DBSPACETEMP
DBSPACETEMP tempdbs1,tempdbs2,tempdbs3
