Centos安裝ArcGIS Server後第一次訪問Manager頁面不成功（提示DIAG026）

1、問題描述

• centos7安裝ArcGIS Servre後，不能訪問到Server的Manager頁面
• 使用server/tools/serverdiag/serverdiag工具監測，提示如下信息：

*** DIAG026: One or more core services was not started.  Start ArcGIS
Server by running the startserver.sh script or restart ArcGIS Server
if it is already started.

2、問題排查

• 查看server日誌信息，日誌位置/server/framework/etc/service/logs/service-0.log，日誌內容如下：

• 查詢相關問題後，確定爲IPV6沒有關閉

3、解決問題

• 使用ifconfig命令查看網卡信息，如果出現inet6 fe80::20c:29ff:fed0:3514說明機器打開了IPV6
• 編輯/etc/sysctl.conf配置，增加net.ipv6.conf.all.disable_ipv6=1

# sysctl settings are defined through files in
# /usr/lib/sysctl.d/, /run/sysctl.d/, and /etc/sysctl.d/.
#
# Vendors settings live in /usr/lib/sysctl.d/.
# To override a whole file, create a new file with the same in
# /etc/sysctl.d/ and put new settings there. To override
# only specific settings, add a file with a lexically later
# name in /etc/sysctl.d/ and put new settings there.
#
# For more information, see sysctl.conf(5) and sysctl.d(5).

net.ipv6.conf.all.disable_ipv6=1

• 編輯/etc/sysconfig/network配置，增加NETWORKING_IPV6=no

# Created by anaconda
NETWORKING_IPV6=no

• 編輯/etc/sysconfig/network-scripts/ifcfg-eno*，修改IPV6INIT爲no

TYPE="Ethernet"
PROXY_METHOD="none"
BROWSER_ONLY="no"
BOOTPROTO="dhcp"
DEFROUTE="yes"
IPV4_FAILURE_FATAL="no"
IPV6INIT="no"
IPV6_AUTOCONF="yes"
IPV6_DEFROUTE="yes"
IPV6_FAILURE_FATAL="no"
IPV6_ADDR_GEN_MODE="stable-privacy"
NAME="ens32"

• 關閉防火請並取消防火牆自啓動
• 再次使用ifconfig命令檢查網卡信息
