Sybase数据库安装及配置
Case库sybase数据库安装安装环境
系统：Red Hat Enterprise Linux AS release 4 (Nahant Update 5)
主机名：db
IP地址：172.16.9.86
内核：2.6.9-55.Elsmp
内存：4G
交换分区：4G
CPU：Intel(R) Xeon(R) 2GHz （2颗，32bits）
安装前准备
1、新建安装用户sybase
[root@db etc]# useradd –d /opt/sybase –m sybase
[root@db etc]# id sybase
uid=505(sybase) gid=505(sybase) groups=505(sybase)
2、修改内核参数
在/etc/sysctl.conf文件中加入如下三行：
kernel.shmmax=1000000000
kernel.exec-shield=0
kernel.exec-shield-randomize=0
然后执行如下命令，使修改生效：
[root@db etc]# sysctl –p
检查修改是否生效：
[root@db etc]# sysctl kernel.shmmax
kernel.shmmax = 1000000000
[root@db etc]# sysctl kernel.exec-shield
kernel.exec-shield = 0
[root@db etc]# sysctl kernel.exec-shield-randomize
kernel.exec-shield-randomize = 0
安装
在图形界面下进行安装
安装目录：/opt/sybase
安装版本：Adaptive Server Enterprise 12.5.2 EBF 11949 linux
以sybase用户登陆服务器图形界面，首先解压安装包
[sybase @db inst]$ tar xvfz ase1252_de_linux.tgz
然后执行安装命令：
[sybase @db inst]$./setup
根据提示进行设置，选择“Typical”安装。
安装后，修改sybase用户的.bash_profile文件。在该文件的末尾加入如下内容：. /opt/sybase/SYBASE.sh。修改完成后，注销用户，然后重新以sybase用户登陆系统。
检查服务是否已经起来：
[sybase@db ~]$ /opt/sybase/ASE-12_5/install/showserver

登陆数据库
[sybase@db ~]$ isql -Usa -P -Sdb
CT-LIBRARY error:
ct_connect(): directory service layer: internal directory control layer error: Requested server name not found.
通过google、baidu，以及重装数据库后，该问题一直没有得到解决，在陈川的帮助下解决，问题处在-S的db应该写成大写DB！
[sybase@db ~]$ isql -Usa -SDB
Password:

and server character set 'iso_1'.

更改数据库属主

The proposed new db owner already is a user in the database or owns the
database.
(return status = 1)
上面命令没有成功更改数据库属主，问题出在con应经是该数据库的用户了，所以应该首先在该库中删除con用户
1> sp_dropuser con
2> go
User has been dropped from current database.
(return status = 0)
1> sp_changedbowner con

System Administrator (SA) role.

解决不能telnet本机5000端口问题
正常运行情况下，应用程序必须能访问5000端口。但是本机的5000端口只有本地才能访问。
[root@db ~]# lsof -i :5000
COMMAND PID USER FD TYPE DEVICE SIZE NODE NAME
dataserve 21221 sybase 13u IPv4 18952868 TCP db:5000 (LISTEN)
dataserve 21221 sybase 14u IPv4 18998135 TCP db:5000->db:45610 (ESTABLISHED)
isql 29121 sybase 6u IPv4 18998134 TCP db:45610->db:5000 (ESTABLISHED)
该命令显示5000端口已经打开，并且已有本地的访问连接，说明数据库的功能没有问题。
[sybase@db sybase]$ netstat -anv | grep 500*
tcp 0 0 127.0.0.1:5000 0.0.0.0:* LISTEN tcp 0 0 127.0.0.1:5001 0.0.0.0:* LISTEN tcp 0 0 127.0.0.1:5002 0.0.0.0:* LISTEN tcp 0 0 0.0.0.0:50008 0.0.0.0:* LISTEN 请注意上面标红的IP地址，表示服务器只监听127.0.0.1的5000端口，显然不对。
检查/etc/hosts表
root@db etc]# cat /etc/hosts
# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1 db localhost.localdomain localhost
172.16.9.85 app
172.16.9.86 db
172.16.9.245 app-ilo
172.16.9.84 app-srv
172.16.9.246 db-ilo
172.16.9.88 db-srv
# Interconnect RAC (Private Network)
172.16.9.95 app_rac
172.16.9.96 db_rac
172.16.9.18 https://www.360docs.net/doc/a116859841.html,
将上面标红的行中的db去掉，然后重启sybase数据库。
[root@db etc]# netstat -anv | grep 500*
