二进制包安装

本文档主要介绍如何用二进制包方式安装GreatSQL数据库，假定本次安装是在CentOS 8.x x86_64环境中安装，并且是以root用户身份执行安装操作。

下载安装包

点击此处二进制包安装 - 图1 (opens new window)下载最新的安装包，下载以下文件：

  • GreatSQL-8.0.32-25-Linux-glibc2.28-x86_64-minimal.tar.xz

运行环境配置

关闭selinux和防火墙

  1. #关闭selinux
  2. $ setenforce=0
  3. $ sed -i '/^SELINUX=/c'SELINUX=disabled /etc/selinux/config
  5. #关闭防火墙
  6. $ systemctl disable firewalld
  7. $ systemctl stop firewalld
  8. $ systemctl disable iptables
  9. $ systemctl stop iptables

另外，要先确认YUM源可用，因为安装GreatSQL时还要先安装其他依赖包，通过YUM安装最省事。

如果需要配置YUM源，可以参考这篇文档二进制包安装 - 图2 (opens new window)。

安装依赖包

安装GreatSQL需要先安装其他依赖包，可执行下面命令完成：

  1. $ yum install -y pkg-config perl libaio-devel numactl-devel numactl-libs net-tools openssl openssl-devel jemalloc jemalloc-devel perl-Data-Dumper perl-Digest-MD5 python2 perl-JSON perl-Test-Simple

如果报告个别依赖包安装失败或者找不到就删掉，然后重试。更详细的请参考：安装准备。

下载二进制包并安装

将下载的二进制包放在安装目录 /usr/local/ 下，并解压缩：

  1. # 下载
  2. $ cd /usr/local
  3. $ wget https://product.greatdb.com/GreatSQL-8.0.32-25/GreatSQL-8.0.32-25-Linux-glibc2.28-x86_64-minimal.tar.xz
  4. #或者用curl
  5. $ curl -o GreatSQL-8.0.32-25-Linux-glibc2.28-x86_64-minimal.tar.xz https://product.greatdb.com/GreatSQL-8.0.32-25/GreatSQL-8.0.32-25-Linux-glibc2.28-x86_64-minimal.tar.xz
  7. #解压缩
  8. $ tar xf GreatSQL-8.0.32-25-Linux-glibc2.28-x86_64-minimal.tar.xz

编辑systemd系统服务文件，增加GreatSQL服务文件：

  1. $ vim /lib/systemd/system/greatsql.service
  3. [Unit]
  4. Description=GreatSQL Server
  5. Documentation=man:mysqld(8)
  6. Documentation=http://dev.mysql.com/doc/refman/en/using-systemd.html
  7. After=network.target
  8. After=syslog.target
  9. [Install]
  10. WantedBy=multi-user.target
  11. [Service]
  13. # some limits
  14. # file size
  15. LimitFSIZE=infinity
  16. # cpu time
  17. LimitCPU=infinity
  18. # virtual memory size
  19. LimitAS=infinity
  20. # open files
  21. LimitNOFILE=65535
  22. # processes/threads
  23. LimitNPROC=65535
  24. # locked memory
  25. LimitMEMLOCK=infinity
  26. # total threads (user+kernel)
  27. TasksMax=infinity
  28. TasksAccounting=false
  30. User=mysql
  31. Group=mysql
  32. #如果是GreatSQL 5.7版本，此处需要改成simple模式，否则可能服务启用异常
  33. #如果是GreatSQL 8.0版本则可以使用notify模式
  34. #Type=simple
  35. Type=notify
  36. TimeoutSec=0
  37. PermissionsStartOnly=true
  38. ExecStartPre=/usr/local/GreatSQL-8.0.32-25-Linux-glibc2.28-x86_64-minimal/bin/mysqld_pre_systemd
  39. ExecStart=/usr/local/GreatSQL-8.0.32-25-Linux-glibc2.28-x86_64-minimal/bin/mysqld $MYSQLD_OPTS
  40. EnvironmentFile=-/etc/sysconfig/mysql
  41. LimitNOFILE = 10000
  42. Restart=on-failure
  43. RestartPreventExitStatus=1
  44. Environment=MYSQLD_PARENT_PID=1
  45. PrivateTmp=false

务必确认文件中目录及文件名是否正确。

执行命令重载systemd，加入 greatsql 服务，如果没问题就不会报错：

  1. $ systemctl daemon-reload

这就安装成功并将GreatSQL添加到系统服务中，后面可以用 systemctl 来管理GreatSQL服务。

编辑GreatSQL全局配置文件 /etc/my.cnf，加入下面内容：

  1. $ vim /etc/my.cnf
  2. [mysql]
  3. socket=/var/lib/mysql/mysql.sock
  5. [mysqld]
  6. user=mysql
  7. datadir=/var/lib/mysql
  8. socket=/var/lib/mysql/mysql.sock
  10. log-error=/var/log/mysqld.log
  11. pid-file=/var/run/mysqld/mysqld.pid

保存退出。

创建mysql系统用户：

  1. $ /sbin/groupadd mysql
  2. $ /sbin/useradd -g mysql mysql -d /dev/null -s /sbin/nologin

创建相关文件夹，并修改用户组：

  1. mkdir /var/run/mysqld/ /var/lib/mysql-files/ /var/lib/mysql/ 
  3. chown mysql:mysql /var/run/mysqld/ /var/lib/mysql-files/ /var/lib/mysql/ /usr/local/GreatSQL-8.0.32-25-Linux-glibc2.28-x86_64-minimal/

编辑mysqld_pre_systemd脚本文件，修改程序目录：

将文件中的 /usr/local/GreatSQL-8.0.32-25-Linux-glibc2.28-x86_64/改为实际安装目录。

启动GreatSQL

执行下面的命令启动GreatSQL服务

  1. $ systemctl start greatsql

检查服务是否已启动，以及进程状态：

  1. $ systemctl status greatsql
  2. ● greatsql.service - GreatSQL Server

可以看到，GreatSQL服务已经正常启动了。

连接登入GreatSQL

采用minimal二进制包安装GreatSQL后，通过log-error日志查看初始化密码，即可登入。

  1. $ cat /var/log/mysqld.log|grep password
  2. [Note] [MY-010454] [Server] A temporary password is generated for root@localhost: NrkNcJya<9f6

若使用了GreatSQL推荐的my.cnf则错误日志路径发生改变，请使用以下命令查看初始化密码

  1. $ $ grep -i root /data/GreatSQL/error.log
  2. ... A temporary password is generated for root@localhost: ji!pjndiw5sJ

复制密码即可登入GreatSQL

  1. $ /usr/local/GreatSQL-8.0.32-25-Linux-glibc2.28-x86_64-minimal/bin/mysql -uroot
  2. Welcome to the MySQL monitor.  Commands end with ; or \g.
