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
(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 (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
3. Loaded: loaded (/usr/lib/systemd/system/greatsql.service; disabled; vendor preset: disabled)

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.
