本文介绍如何在CentOS环境下编译GreatSQL RPM包。
运行环境是docker中的CentOS 8 x86_64：
代码语言：javascript复制$ docker -v
Docker version 20.10.10, build b485636
$ docker run -itd --hostname c8 --name c8 centos bash
a0a2128591335ef41e6faf46b7e79953c097500e9f033733c3ab37f915b69439
$ docker exec -it c8 bash
1、准备工作
1.1、配置yum源
开始编译之前，需要先配置好yum源，方便安装一些辅助工具。
在这里采用阿里云的yum源：
代码语言：javascript复制[root@c8 /]# rm -f /etc/yum.repos.d/* &&
curl -o /etc/yum.repos.d/CentOS-Base.repo https://mirrors.aliyun.com/repo/Centos-vault-8.5.2111.repo &&
sed -i -e '/mirrors.cloud.aliyuncs.com/d' -e '/mirrors.aliyuncs.com/d' /etc/yum.repos.d/CentOS-Base.repo &&
yum clean all && yum makecache
1.2、安装编译所需要的软件包
安装 rmp-build 包，它会附带安装其他必要的相关依赖包：
[root@c8 /]# dnf install -y rpm-build
1.3 创建构建RPM包所需的目录
创建相应的目录
代码语言：javascript复制[root@c8 /]# mkdir -p /root/rpmbuild/SOURCES
1.4 下载GreatSQL源码包
戳此链接 https://gitee.com/GreatSQL/GreatSQL/releases/tag/GreatSQL-8.0.32-25，找到 greatsql-8.0.32-25.tar.xz 下载GreatSQL源码包，放在上面创建的 /root/rpmbuild/SOURCES 目录下，并解压缩。
1.5 下载greatsql.spec文件
戳此链接 https://gitee.com/GreatSQL/GreatSQL-Doc/blob/master/build-gs/greatsql.spec，下载 greatsql.spec 文件，放在上面创建的 /root/rpmbuild/ 目录下。
1.6 下载boost源码包
编译GreatSQL 8.0.32-25版本需要配套的boost版本是1.77，戳此链接下载 https://boostorg.jfrog.io/artifactory/main/release/1.77.0/source/boost_1_77_0.tar.gz，放在上面创建的 /root/rpmbuild/SOURCES 目录下。
1.7 下载rpcsvc-proto包并编译安装
编译GreatSQL需要配套rpcsvc-proto包，戳此链接下载 https://github.com/thkukuk/rpcsvc-proto/releases/download/v1.4/rpcsvc-proto-1.4.tar.gz，放在 /tmp/ 目录下。
2、开始准备编译GreatSQL RPM包
从GreatSQL源码包中拷贝几个必要的文件
代码语言：javascript复制[root@c8 /]# cd /root/rpmbuild/SOURCES/greatsql-8.0.32-25/build-gs/rpm
[root@c8 rpm]# cp filter-*sh mysqld.cnf mysql-5.7-sharedlib-rename.patch mysql.init mysql_config.sh /root/rpmbuild/SOURCES/
修改 greatsql.spec 文件中的部分内容：
[root@c8 rpm]# vim /root/rpmbuild/greatsql.spec
...
%global greatsql_version 25
%global revision db07cc5cb73
...
SOURCE0: greatsql-8.0.32-25.tar.xz
...
SOURCE10: boost_1_77_0.tar.gz
...
%changelog
* Fri Dec 29 2023 GreatSQL <greatsql@greatdb.com> - 8.0.32-25.1
- Release GreatSQL-8.0.32-25.1
* Wed Jun 7 2023 GreatSQL <greatsql@greatdb.com> - 8.0.32-24.1
- Release GreatSQL-8.0.32-24.1
...
开始尝试编译RPM包
代码语言：javascript复制[root@c8 rpm]# cd /root/rpmbuild
[root@c8 rpmbuild]# rpmbuild --define "_topdir /root/rpmbuild/" -bb ./greatsql.spec
在使用 rpmbuild 编译RPM包时，通常会选择加上 -ba 或 -bb 参数，下面是关于这两个参数的注释：
-ba Build binary and source packages (after doing the %prep, %build, and %install stages).
-bb Build a binary package (after doing the %prep, %build, and %install stages).
简单说，-ba 会编译出RPM包和SRPM包，而 -bb 只会编译出RPM包。
第一次运行时，大概率会提示N多依赖包缺失，先耐心地逐个安装上：
代码语言：javascript复制[root@c8 rpmbuild]# rpmbuild --define "_topdir /root/rpmbuild/" -bb ./greatsql.spec
...

...
warning: bogus date in %changelog: Wed Jun 6 2022 GreatSQL <greatsql@greatdb.com> - 8.0.25-16.1
error: Failed build dependencies:

cmake >= 3.6.1 is needed by greatsql-8.0.32-25.1.el8.x86_64
...
zlib-devel is needed by greatsql-8.0.32-25.1.el8.x86_64
这里贴一下我用上述干净docker环境中安装的一些依赖包：
代码语言：javascript复制[root@c8 rpmbuild]# dnf install -y bison cmake cyrus-sasl-devel gcc-c gcc-toolset-11 gcc-toolset-11-annobin-plugin-gcc libaio-devel libcurl-devel libtirpc-devel m4 make ncurses-devel numactl-devel openldap-devel openssl openssl-devel pam-devel perl perl-Carp perl-Data-Dumper perl-Errno perl-Exporter perl-File-Temp perl-Getopt-Long perl-JSON perl-Memoize perl-Time-HiRes readline-devel time zlib-devel
由于安装了 gcc-toolset-11 包，需要执行下面的命令才能切换到 gcc11 版本环境中，并确认gcc、cmake的版本是否符合要求：
[root@c8 rpmbuild]# source /opt/rh/gcc-toolset-11/enable
[root@c8 rpmbuild]# gcc --version
gcc (GCC) 11.2.1 20210728 (Red Hat 11.2.1-1)
Copyright (C) 2021 Free Software Foundation, Inc.
This is free software; see the source for copying conditions. There is NO
warranty; not even for MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
[root@c8 rpmbuild]# cmake --version
cmake version 3.20.2
CMake suite maintained and supported by Kitware (kitware.com/cmake).
还需要编译安装rpcsvc-proto依赖包
[root@c8 rpmbuild]# cd /tmp/
[root@c8 tmp]# tar xf rpcsvc-proto-1.4.tar.gz
[root@c8 tmp]# cd rpcsvc-proto-1.4
[root@c8 rpcsvc-proto-1.4]# ./configure && make && make install
...
make[2]: Leaving directory '/tmp/rpcsvc-proto-1.4'
make[1]: Leaving directory '/tmp/rpcsvc-proto-1.4'
安装完这些依赖包后，再次开始尝试编译RPM包。
代码语言：javascript复制[root@c8 rpcsvc-proto-1.4]# cd /root/rpmbuild/
# 将编译过程输出到日志文件中，更方便观察的排查错误
[root@c8 rpmbuild]# rpmbuild --define "_topdir /root/rpmbuild/" -bb ./greatsql.spec > ./rpmbuild.log 2>&1
warning: Macro expanded in comment on line 787: %{_mandir}/man1/mysql.server.1*
warning: Macro expanded in comment on line 956: %{_datadir}/mysql-*/audit_log_filter_linux_install.sql

umask 022
cd /root/rpmbuild//BUILD
cd /root/rpmbuild/BUILD
rm -rf greatsql-8.0.32-25
...
如果编译失败了，会有类似这样的结果：
代码语言：javascript复制 bogus date in %changelog: Wed Jun 6 2022 GreatSQL <greatsql@greatdb.com> - 8.0.25-16.1
Bad exit status from /var/tmp/rpm-tmp.k8RLOL (%build)
只需打开 /root/rpmbuild/rpmbuild.log 文件，搜索 error/fail 等关键字（不区分大小写）应该就能分析出错误原因了。
解决完错误原因，再一次重试编译，这次应该顺利了，耐心等着吧。在这过程中，我们还可以通过观察 /root/rpmbuild/rpmbuild.log 文件了解编译的进度情况，例如下面这样，可见进度大约到了91%，胜利在望 ~

...
编译GreatSQL RPM包的过程中要做两遍，一次编译出release包，一次编译出debug包，所以会有一点点费时，正好泡杯好茶安心喝着就是了。
最后，查看编译结果，会有类似下面的日志：
代码语言：javascript复制[root@c8 rpmbuild]# tail rpmbuild.log

/usr/bin/rm -rf /root/rpmbuild/BUILDROOT/greatsql-8.0.32-25.1.el8.x86_64
exit 0
再看下编译生成的RPM文件包：
代码语言：javascript复制[root@c8 rpmbuild]# du -sch *

大功告成。
3、安装GreatSQL
将编译产生的RPM包文件拷贝到另外一个全新的docker CentOS 8环境下，测试安装是否顺利。下面略过拷贝文件以及新docker镜像环境初始化过程，直接开始安装：
代码语言：javascript复制[root@cc8 cc8]# rpm -ivh *rpm

看起来一切都很顺利，成功搞定。
全文完。
Enjoy GreatSQL :)
