二进制包安装

本节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

#关闭selinux
$ setenforce=0
$ sed -i '/^SELINUX=/c'SELINUX=disabled /etc/selinux/config

#关闭防火墙
$ systemctl disable firewalld
$ systemctl stop firewalld
$ systemctl disable iptables
$ 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。

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：

$ 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：

# 下载
$ cd /usr/local
$ wget https://product.greatdb.com/GreatSQL-8.0.32-25/GreatSQL-8.0.32-25-Linux-glibc2.28-x86_64-minimal.tar.xz
#或者用curl
$ 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

#解压缩
$ 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：

$ vim /lib/systemd/system/greatsql.service

[Unit]

EnvironmentFile=-/etc/sysconfig/mysql
LimitNOFILE = 10000
Restart=on-failure
RestartPreventExitStatus=1
Environment=MYSQLD_PARENT_PID=1
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：

$ 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：

$ vim /etc/my.cnf
[mysql]
socket=/var/lib/mysql/mysql.sock

[mysqld]
user=mysql
datadir=/var/lib/mysql
socket=/var/lib/mysql/mysql.sock

log-error=/var/log/mysqld.log
pid-file=/var/run/mysqld/mysqld.pid

保存退出。

创建mysql系统用户：

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

创建相关文件夹，并修改用户组：

mkdir /var/run/mysqld/ /var/lib/mysql-files/ /var/lib/mysql/ 

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

$ systemctl start greatsql

检查服务是否已启动，以及进程状态：

$ systemctl status greatsql

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。

$ cat /var/log/mysqld.log|grep password
[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

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

复制密码即可登入GreatSQL
