服务器环境准备






2.1 测试数据盘的随机同步写入性能

time dd if=/dev/zero of=test bs=1M count=1024 oflag=dsync1024+0 records in 1024+0 records out1073741824 bytes (1.1 GB) copied, 17.4811 s, 61.4 MB/sreal 0m17.482suser 0m0.002ssys 0m0.748s
2.2 较准机器的时间 
  • 创建定时任务前,确保ntp / chrony 服务关闭

  • 创建计划任务进行时间同步

crontab –e       (写入以下内容) #NTP服务器可自行选择*/20 * * * * /usr/sbin/ntpdate ntpupdate.tencentyun.com >/dev/null &

2.3 防火墙与selinux配置

  • 关闭SELinux

setenforce 0
  • 设置SELinux开机不自启动

vi /etc/sysconfig/selinux将其中的SELINUX= XXXXXX修改为SELINUX=disabled
  • 关闭防火墙&禁止防火墙开机自启

2.4 修改limits.conf参数(生产环境)

[root@tbase01]#cat /etc/security/limits.conf#准许单个进程打开文件数* soft    nofile  131072 * hard    nofile  131072 #准放运行的进程数* soft    nproc   131072 * hard    nproc   131072 #限制内核文件的大小* soft    core    unlimited * hard    core    unlimited 

2.5 修改内核参数sysctl.conf(生产环境)

[root@tbase01]#  vi /etc/sysctl.conf#所有在消息队列中的消息总和的最大值(msgmnb=64k)kernel.msgmnb = 65536#指定内核中消息队列中消息的最大值(msgmax=64k)kernel.msgmax = 65536#共享内存总量,以页为单位(4K/页),默认这个值足够大了kernel.shmall = 4294967296 #单个共享内存段的最大值 ,这个值需要大到让应用的内存段不用分成多个创建,否则性能会下降kernel.shmmax=137438953472 #可以创建的内存段数 ,默认这个值足够大了kernel.shmmni = 4096 #4个数据分别对应:SEMMSL、SEMMNS、SEMOPM、SEMMNI这四个核心参数#SEMMSL :用于控制每个信号集的最大信号数量,建议最小值为postgresql最大连接数+10#SEMOPM:每个 semop 系统调用可以执行的信号操作的数量。建议设置 SEMOPM 等于SEMMSL 。#SEMMNI :内核参数用于控制整个 Linux 系统中信号集的最大数量,建议128#SEMMNS:用于控制整个 Linux 系统中信号(而不是信号集)的最大数,为SEMMSL * SEMMNI kernel.sem = 50100 64128000 50100 1280 #准许系统所有进程一共可以打开的文件数量fs.file-max = 6553600#系统允许的最大异步IO队列长度fs.aio-max-nr = 1048576#增大locale port数量,默认是从32768开始net.ipv4.ip_local_port_range = 1024 65535 #keepalive认定探测失效时间,默认是2小时,7200秒net.ipv4.tcp_keepalive_time = 60 #在认定连接失效之前,发送多少个TCP的keepalive探测包。缺省值是9net.ipv4.tcp_keepalive_probes = 6 #每隔多少秒重新发送keepalive探测包,默认是75秒 net.ipv4.tcp_keepalive_intvl = 10net.ipv4.ip_forward=1vm.dirty_background_bytes = 102400000
2.6 主机名与IP配置 
  • 修改主机名

hostnamectl set-hostname XXXXXX
  • IP地址配置

IP地址无特别要求,可以存在多个网段,只能保证网络是连通的就行。
  • 带宽要求

同IDC,同城最好是万兆,并且要求是低于3ms的延迟。异地视要同步数据量要求,在做备机时需要比较高的带宽,延迟按设计是30ms左右。

2.7 sshd配置

  • 修改/etc/ssh/sshd_config配置

vi /etc/ssh/sshd_configUseDNS no
  • 修改完成后重启sshd服务

CentOS 6 版本service sshd restartCentOS 7 版本systemctl restart sshd


应用程序部署






3.1 上传安装包并解压

  • 上传到/root目录下

[root@tbase01~]# pwd/root[root@tbase01~]# unzip package_name.zip
  • 如果安装包是tar.gz包,则需要这样解压

tar -zxf package_name.tar.gz

3.2 配置安装选项


[root@tbase01~ ]# vi  tbase_mgr/conf/role.info #eth ip idc_name root password role( OssCenterMaster OssCenterSlave OssAgent Confdb Alarm TStudio Zookeeper)#Notice: The machine that will be installed OssCenterMaster or OssCenterSlave can't be installed OssAgent ens33 192.168.43.129 idc_1 root oracle OssCenterMaster|Confdb|TStudio|Etcdens33 192.168.43.130 idc_1 root oracle OssCenterSlave|Confdb|Alarm #Etcd组件是confdb倒换和center倒换的容灾组件,Etcd部署个数必须是奇数个#Etcd建议跟center或者confdb部署在一起,OssCenter支持一主多备。如果机器数量有足够多,除部署以上所示组件的两台机器,其他机器可以只部署OssAgent即可#(建议最少部署3个Etcd组件,可靠性更高)。

3.3 运行安装程序

[root@tbase01 tbase_mgr]# ./tbase_mgr.sh install Hey, Welcome and now we will install TBase OSS by the flowing steps:  0. Check role configuration read from conf/role.info ...  1. Install some base rpm packages such as dos2unix/createrepo/expect and so on ...  2. Check root password and do some initalization on all machines read from conf/role.info ...  3. Check package requires ...  4. Create OS user tbase specifided in conf/oss/oss_init.conf  ...  5. Create yum repository which store all the rpm packages needed by TBase OSS ...  6.

3.5 安装失败解决办法

  • 在安装过程中如果遇到失败,先查看tbase_mgr/logs文件夹下的日志文件

[root@tbase01 logs]# cd /root/tbase_mgr/logs[root@tbase01 logs]# lltotal 780-rw------- 1 root root    784 Dec  1 22:30 authorized_keys.root-rw-r--r-- 1 root root    392 Dec  1 22:30 authorized_keys.root.192.168.43.129-rw-r--r-- 1 root root    392 Dec  1 22:30 authorized_keys.root.192.168.43.130-rw-r--r-- 1 root root 524730 Dec  1 22:39 tbase_mgr.sh.info.log.2020-12-01-rw-r--r-- 1 root root  38726 Dec  4 17:07 tbase_mgr.sh.info.log.2020-12-04-rw-r--r-- 1 root root  70527 Dec  5 22:10 tbase_mgr.sh.info.log.2020-12-05-rw-r--r-- 1 root root   4622 Dec  6 00:07 tbase_mgr.sh.info.log.2020-12-06-rw-r--r-- 1 root root 133901 Dec  7 15:11 tbase_mgr.sh.info.log.2020-12-07
  • 在提示查看的日志文件的末尾,有报错中的具体执行语句,手动执行即可显示详细的错误信息

  • 解决后再次执行安装程序即可

[root@tbase01 TBase_mgr]# sh tbase_mgr.sh install
  • docker版本与内核冲突

如果docker版本与内核冲突,我们可以忽略安装docker,这样的Tstudio组件也要放弃安装以下是修改方法:编辑tbase_mgr.sh文件,修改以下内容:1)把tstudio_install  > /dev/null 2>&1注释掉2)把yum install -y dos2unix expect lrzsz net-tools lsof createrepo httpd httpd-tools php docker中“docker”删除如果一定要安装tstduio,找到当前内核版本下的docker,安装好后,再独立部署tstudio组件。

3.6 yum安装源恢复方法

[root@tbase01 TBASE_mgr]# rm -rf /etc/yum.repos.d/PGXZ.repo[root@tbase01 TBASE_mgr]# mv /etc/yum.repos.d/backup/* /etc/yum.repos.d/[root@tbase01 TBASE_mgr]# yum makecache[root@tbase01 TBASE_mgr]# yum clean all

所有机器都要恢复,如不再需要安装其它软件,可以不需要恢复


安装失败问题汇总






4.1 IDC参数写为hostname错误

[root@tbase01 tbase_mgr]# cat logs/tbase_mgr.sh.info.log.2020-09-25 [ 2020-09-25 11:08:33 ] [ read_machine_info ] [ERROR]: Agent must be specified, exit[ 2020-09-25 11:08:33 ] [ check_machine_idc ] [ERROR]: The machine_ip in (tbase01), but the tbase01 is not exist.[ 2020-09-25 11:08:33 ] [ check_machine_idc ] [ERROR]: Fail to check machine idc in idc_1:local, exit[ 2020-09-25 11:08:33 ] [ check_progress ] [ERROR]: from [read_machine_info] Abort progress due to an error occurs during step above, check logs/tbase_mgr.sh.info.log.2020-09-25 for more details ...

解决方法

--这里idc_1在OSS配置文件中写死,不建议修改查看tbase_mgr/conf/role.info配置文件里的idc配置,不是hostname[root@tbase01 tbase_mgr]# cat conf/role.infoeth0 192.168.43.129 idc_1 root xxxxxxxx OssCenterMaster|Confdb|TStudio|Etcdeth0 192.168.43.130 idc_1 root xxxxxxxx OssCenterSlave|Confdb|Alarm

4.2、安装日志报yum源问题

  • httpd权限配置问题

Other repos take up 737 M of disk space (use --verbose for details)[ 2020-09-25 11:26:09 ] [ conf_yum_repo ] [ERROR]: Failed to exec: ssh -o ConnectTimeout=10 -o StrictHostKeyChecking=no root@192.168.43.199 "yum -y install dos2unix expect readline createrepo net-tools lsof uuid" < /dev/null, retcode: 1, retmsg: Loaded plugins: fastestmirror, langpacksDetermining fastest mirrors, exit[ 2020-09-25 11:26:09 ] [ check_progress ] [ERROR]: from [conf_yum_repo] Abort progress due to an error occurs during step above, check logs/tbase_mgr.sh.info.log.2020-09-25 for more details ...

解决方法

1、通过执行日志中的命令,发现yum源因权限问题无法访问http://192.168.43.199/repodata/repomd.xml: [Errno 14] HTTP Error 403 - Forbidde 2、修改/etc/httpd/conf/httpd.conf将denied改为granted /> AllowOverride none Require all granted
  • 安装包冲突问题

Error: Package: policycoreutils-python-2.5-11.el7_3.x86_64 (PGXZ) Requires: policycoreutils = 2.5-11.el7_3 Installed: policycoreutils-2.5-29.el7.x86_64 (@anaconda) policycoreutils = 2.5-29.el7 Available: policycoreutils-2.5-11.el7_3.x86_64 (PGXZ) policycoreutils = 2.5-11.el7_3You could try using --skip-broken to work around the problemYou could try running: rpm -Va --nofiles --nodigest

解决方法

安装包冲突,需要删除原来的包yum -y remove policycoreutils-2.5-29.el7.x86_64

4.3、 Etcd数量为偶数的问题

[ 2020-12-01 15:41:59 ]  [parse_machine_role] [Info]: 192.168.43.130, OssCenterSlave|Confdb|Alarm|Etcd r=[Alarm][ 2020-12-01 15:41:59 ]  [parse_machine_role] [Info]: 192.168.43.130, OssCenterSlave|Confdb|Alarm|Etcd r=[Etcd][ 2020-12-01 15:41:59 ] [ parse_machine_role ] [Info]: XZEtcds 192.168.43.130 r=[Etcd][ 2020-12-01 15:41:59 ] [ read_machine_info ] [ERROR]: Agent must be specified, exit[ 2020-12-01 15:41:59 ] [ read_machine_info ] [ERROR]: The number of Etcd must be a odd number. etcd_cnt=2, etcd_server=192.168.43.129[ 2020-12-01 15:41:59 ] [ check_progress ] [ERROR]: from [read_machine_info] Abort progress due to an error occurs during step above, check logs/tbase_mgr.sh.info.log.2020-12-01 for more details ...

解决方案

查看role.info,发现Etcd配置了两个,必须为奇数[root@tbase01 tbase_mgr]# cat conf/role.infoens33 192.168.43.129 cdh root oracle OssCenterMaster|Confdb|TStudio|Etcdens33 192.168.43.130 cdh02 root oracle OssCenterSlave|Confdb|Alarm|Etcd  --删掉Etcd组件

4.4、root密码错误

[ 2020-12-01 15:51:32 ] [ selinux_policy_off ] [INFO]: spawn_pswd=oracle1[ 2020-12-01 15:51:32 ] [ selinux_policy_off ] [INFO]: after spawn_pswd=oracle1[ 2020-12-01 15:51:34 ] [ selinux_policy_off ] [ERROR]: Failed to exec: ssh -o ConnectTimeout=10 -o StrictHostKeyChecking=no root@192.168.43.129 "setenforce 0;iptables -I INPUT -j ACCEPT;service iptables save", retcode: 3, exit

解决方案

查看role.info,发现root密码错误 [root@tbase01 tbase_mgr]# cat conf/role.infoens33 192.168.43.129 idc_1 root oracle1 OssCenterMaster|Confdb|TStudio|Etcdens33 192.168.43.130 idc_1 root oracle2 OssCenterSlave|Confdb|Alarm

4.5、网卡参数错误

[ 2020-12-01 16:00:46 ] [ check_net_eth ] [ERROR]: 192.168.43.129 not match 1ens33

解决方案

查看role.info,发现网络端口不存在[root@tbase01 tbase_mgr]# cat conf/role.info1ens33 192.168.43.129 idc_1 root oracle1 OssCenterMaster|Confdb|TStudio|Etcdens33 192.168.43.130 idc_1 root oracle2 OssCenterSlave|Confdb|Alarm

4.6、IP错误

测试发现,这步不影响YUM安装软件[ 2020-12-01 16:04:33 ] [ selinux_policy_off ] [ERROR]: Failed to exec: ssh -o ConnectTimeout=10 -o StrictHostKeyChecking=no root@192.168.43.131 "sed -i 's/SELINUX=enforcing/SELINUX=disabled/' /etc/selinux/config", retcode: 5, exit 

解决方案

查看role.info,发现IP[root@tbase01 tbase_mgr]# cat conf/role.infoens33 192.168.43.129 idc_1 root oracle OssCenterMaster|Confdb|TStudio|Etcdens33 192.168.43.131 idc_1 root oracle OssCenterSlave|Confdb|Alarm

4.7、不进入 tbase_mgr目录执行脚本

sh tbase_mgr/tbase_mgr.sh install日志报错:This system is not registered with an entitlement server. You can use subscription-manager to register.Determining fastest mirrors, exit

解决方法

[root@tbase01 tbase_mgr]# cd /root/Centos7/tbase_mgr[root@tbase01 tbase_mgr]# pwd/root/Centos7/tbase_mgr[root@tbase01 tbase_mgr]# sh tbase_mgr.sh install

4.8、docker安装失败

[ 2020-12-01 20:28:02 ] [ tstudio_install ] [ERROR]: Failed to exec: ssh -o ConnectTimeout=10 -o StrictHostKeyChecking=no root@192.168.43.129 "service docker start && sleep 10 && docker info" < /dev/null, retcode: 1, retmsg: , exit[ 2020-12-01 20:28:02 ] [ check_progress ] [ERROR]: from [tstudio_install] Abort progress due to an error occurs during step above, check logs/tbase_mgr.sh.info.log.2020-12-01 for more details ...

解决

测试上述命令,发现docker进程启动失败
