本次介紹如何利用Docker來將GreatSQL源碼編譯成二進位文件，以及製作二進位包、RPM包等。
本文介紹的運行環境是CentOS 7.9：
[root@greatsql ~]# cat /etc/redhat-release
CentOS Linux release 7.9.2009 (Core)
[root@greatsql ~]# uname -a
Linux greatsql 3.10.0-1160.11.1.el7.x86_64 #1 SMP Fri Dec 18 16:34:56 UTC 2020 x86_64 x86_64 x86_64 GNU/Linux
開始編譯之前，建議先配置好yum源，方便安裝一些工具。
以阿里、騰訊兩大雲主機為例，可以這樣配置（兩個yum源自行二選一）：
[root@greatsql ~]# mv /etc/yum.repos.d/CentOS-Base.repo{,.orig}
#阿里雲
[root@greatsql ~]# wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo
#騰訊雲
[root@greatsql ~]# wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.cloud.tencent.com/repo/centos7_base.repo
#替換完後，更新緩存
[root@greatsql ~]# yum clean all
[root@greatsql ~]# yum makecache
安裝docker，並啟動docker進程。
[root@greatsql]# yum install -y docker
[root@greatsql]# systemctl start docker
分別下載幾個編譯過程中需要的依賴包：
boost, https://boostorg.jfrog.io/artifactory/main/release/1.73.0/source/boost_1_73_0.tar.gzgit, https://github.com/git/git/archive/v2.27.0.tar.gz, 下載後重命名為 git-v2.27.0.tar.gzpatchelf, https://github.com/NixOS/patchelf/archive/refs/tags/0.12.tar.gz, 下載後重命名為 patchelf-0.12.tar.gzrpcsvc-proto, https://github.com/thkukuk/rpcsvc-proto/releases/download/v1.4/rpcsvc-proto-1.4.tar.gz下載GreatSQL源碼包：https://gitee.com/GreatSQL/GreatSQL/archive/greatsql-8.0.25-15.tar.gz
1.4、構建docker鏡像用下面這份Dockerfile構建鏡像，這裡以CentOS 7為例：
FROM centos:7
ENV LANG en_US.utf8
RUN yum install -y epel-release && \
curl -o /etc/yum.repos.d/CentOS-Base.repo http://mirrors.cloud.tencent.com/repo/centos7_base.repo && \
yum clean all && \
yum makecache
RUN yum install -y yum-utils && \
yum install -y wget diffutils net-tools vim git gcc gcc-c++ automake libtool cmake cmake3 \
make psmisc openssl-devel zlib-devel readline-devel bzip2-devel expat-devel gflags-devel \
bison bison-devel flex wget unzip libcurl-devel libevent-devel libffi-devel lz4-devel lz4-static \
file clang bzip2 snappy-devel libxml2-devel libtirpc libtirpc-devel numactl-devel numactl-libs \
numactl gtest-devel openldap-devel openldap-clients rpcgen pam-devel valgrind boost-devel rpm* tar \
centos-release-scl libzstd libzstd-static libzstd-devel perl-Env perl-JSON time libaio-devel \
ncurses-devel ncurses-libs pam python-devel redhat-lsb-core scl-utils-build pkg-config ccache
RUN yum install -y devtoolset-10-gcc*
RUN echo 'scl enable devtoolset-10 bash' >> /root/.bash_profile
# update git
COPY git-v2.27.0.tar.gz /tmp/
RUN cd /tmp/ && tar -xzvf git-v2.27.0.tar.gz && cd git-2.27.0 && make prefix=/opt/git/ all && make prefix=/opt/git/ install
RUN mv /usr/bin/git /usr/bin/git.bk && ln -s /opt/git/bin/git /usr/bin/git
# update patchelf 0.12
COPY patchelf-0.12.tar.gz /tmp/
RUN cd /tmp && tar -xzvf patchelf-0.12.tar.gz && cd patchelf && ./bootstrap.sh && ./configure && make && make install
COPY rpcsvc-proto-1.4.tar.gz /tmp/rpcsvc-proto-1.4.tar.gz
RUN tar zxvf /tmp/rpcsvc-proto-1.4.tar.gz -C /tmp && cd /tmp/rpcsvc-proto-1.4/ && ./configure && make && make install
RUN rm -fr /tmp/*
COPY boost_1_73_0.tar.gz /opt/
RUN ln -fs /usr/bin/cmake3 /usr/bin/cmake
開始構建docker鏡像，成功後再保存到本地並導入本地鏡像：
[root@greatsql ~]# docker build -t centos7-greatsql .
... ...
[root@greatsql ~]# docker save -o centos7-greatsql.tar centos7-greatsql
[root@greatsql ~]# docker load -i centos7-greatsql.tar
創建一個docker容器，並將GreatSQL源碼包copy進去：
[root@greatsql ~]# docker run -itd --name greatsql --hostname=greatsql centos7-greatsql bash
[root@greatsql ~]# docker cp /opt/greatsql-8.0.25-15.tar.gz greatsql:/opt/
[root@greatsql ~]# docker exec -it greatsql bash
[root@greatsql /]# ls -l /opt/
-rw-- 1 root root 128699082 Jul 27 06:56 boost_1_73_0.tar.gz
drwxr-xr-x 5 root root 4096 Jul 28 06:38 git
-rw-- 1 1000 1000 526639994 Jul 27 05:59 greatsql-8.0.25-15.tar.gz
drwxr-xr-x 3 root root 4096 Jul 28 06:34 rh
進入容器後，解壓GreatSQL和boost源碼包：
[root@greatsql /]# tar zxf /opt/greatsql-8.0.25-15.tar.gz -C /opt
[root@greatsql /]# tar zxf /opt/boost_1_73_0.tar.gz -C /opt/greatsql-8.0.25-15/
如果只是想在本機使用，則可以只編譯出二進位文件即可，無需打包或製作RPM包。用下面的命令進行編譯：
[root@greatsql /]# cmake3 /opt/greatsql-8.0.25-15 \
-DBUILD_TESTING=OFF -DUSE_GTAGS=OFF -DUSE_CTAGS=OFF \
-DUSE_ETAGS=OFF \-DUSE_CSCOPE=OFF -DWITH_TOKUDB=OFF \
-DBUILD_CONFIG=mysql_release -DCMAKE_BUILD_TYPE=RelWithDebInfo \
-DFEATURE_SET=community \
-DCMAKE_INSTALL_PREFIX=/usr/local/GreatSQL-8.0.25-15-Linux \
-DMYSQL_DATADIR=/usr/local/GreatSQL-8.0.25-15-Linux/data \
-DROUTER_INSTALL_LIBDIR=/usr/local/GreatSQL-8.0.25-15-Linux/lib/mysqlrouter/private \
-DROUTER_INSTALL_PLUGINDIR=/usr/local/GreatSQL-8.0.25-15-Linux/lib/mysqlrouter/plugin \
-DCOMPILATION_COMMENT='GreatSQL (GPL), Release 15, Revision e36e91b7242' \
-DWITH_PAM=ON -DWITH_ROCKSDB=ON -DROCKSDB_DISABLE_AVX2=1 -DROCKSDB_DISABLE_MARCH_NATIVE=1 \
-DWITH_INNODB_MEMCACHED=ON -DWITH_ZLIB=bundled -DWITH_NUMA=ON -DWITH_LDAP=system \
-DFORCE_INSOURCE_BUILD=1 -DWITH_LIBEVENT=bundled -DWITH_ZSTD=bundled \
-DWITH_BOOST=/opt/greatsql-8.0.25-15/boost_1_73_0
cmake過程如果沒報錯，就會輸出類似下面的結果：
... ...
-- Build files have been written to: /opt/greatsql-8.0.25-15
接下來可以開始正式編譯了：
[root@greatsql ~]# make -j30 VERBOSE=1 && make install
參數 -j30 設定為並行編譯的邏輯CPU數量，可以指定為比邏輯CPU總數少一點，不要把所有CPU都跑滿。
編譯完成後，就會將二進位文件安裝到 /usr/local/GreatSQL-8.0.25-15-Linux.x86_64 目錄下。
2.2、編譯並打包成二進位文件包或RPM包如果是想要在編譯完後也能拷貝到其他伺服器上使用，也可以直接編譯生成二進位包或RPM包，可以用下面的命令編譯：
[root@greatsql ~]# cd /opt/greatsql-8.0.25-15/build-gs/
[root@greatsql ~]# export your_processors=30 #同上，修改並行CPU數量
[root@greatsql ~]# export TAR_PROCESSORS=-T$your_processors
[root@greatsql ~]# export MAKE_JFLAG=-j$your_processors
[root@greatsql ~]# mkdir -p workdir
[root@greatsql ~]# cp /opt/boost_1_73_0.tar.gz /opt/greatsql-8.0.25-15/build-gs/
[root@greatsql ~]# cp /opt/greatsql-8.0.25-15.tar.gz /opt/greatsql-8.0.25-15/build-gs/workdir/
# 選擇1：編譯並打包成二進位包
[root@greatsql ~]# bash -xe ./percona-server-8.0_builder.sh --builddir=`pwd`/workdir --get_sources=0 --install_deps=0 --with_ssl=1 --build_tarball=1 --build_src_rpm=0 --build_rpm=0 --no_git_info=1 --local_boost=1
# 選擇2：編譯並打包成RPM包
[root@greatsql ~]# bash -xe ./percona-server-8.0_builder.sh --builddir=`pwd`/workdir --get_sources=0 --install_deps=0 --with_ssl=1 --build_tarball=0 --build_src_rpm=1 --build_rpm=1 --no_git_info=1 --local_boost=1
編譯過程中如果遇到類似下面的patchelf報錯：
+ patchelf --replace-needed libreadline.so.7 libreadline.so bin/mysql
patchelf: cannot normalize PT_NOTE segment: non-contiguous SHT_NOTE sections
可以參考這個patch：patchelf: Fix alignment issues with contiguous note sections #275，修改下源碼，在容器裡重新手動編譯patchelf。
編譯結束後，就會在 /opt/greatsql-8.0.25-15/build-gs/workdir/ 目錄下生成相應的二進位包、RPM包：
[root@greatsql build-gs]# du -sh workdir/TARGET/
40M workdir/TARGET/GreatSQL-8.0.25-15-Linux-glibc2.17-x86_64-minimal.tar.xz
500M workdir/TARGET/GreatSQL-8.0.25-15-Linux-glibc2.17-x86_64.tar.xz
[root@greatsql build-gs]# du -sh workdir/rpm/greatsql-*
14M workdir/rpm/greatsql-client-8.0.25-15.1.el8.x86_64.rpm
30M workdir/rpm/greatsql-client-debuginfo-8.0.25-15.1.el8.x86_64.rpm
3.4M workdir/rpm/greatsql-debuginfo-8.0.25-15.1.el8.x86_64.rpm
23M workdir/rpm/greatsql-debugsource-8.0.25-15.1.el8.x86_64.rpm
2.1M workdir/rpm/greatsql-devel-8.0.25-15.1.el8.x86_64.rpm

13M workdir/rpm/greatsql-rocksdb-8.0.25-15.1.el8.x86_64.rpm
204M workdir/rpm/greatsql-rocksdb-debuginfo-8.0.25-15.1.el8.x86_64.rpm
60M workdir/rpm/greatsql-server-8.0.25-15.1.el8.x86_64.rpm
343M workdir/rpm/greatsql-server-debuginfo-8.0.25-15.1.el8.x86_64.rpm
1.4M workdir/rpm/greatsql-shared-8.0.25-15.1.el8.x86_64.rpm
2.5M workdir/rpm/greatsql-shared-debuginfo-8.0.25-15.1.el8.x86_64.rpm
440M workdir/rpm/greatsql-test-8.0.25-15.1.el8.x86_64.rpm
18M workdir/rpm/greatsql-test-debuginfo-8.0.25-15.1.el8.x86_64.rpm
這就可以用在copy到其他伺服器上安裝使用了。
3、初始化GreatSQL本次計劃在下面3臺伺服器上部署MGR集群：
nodeipdatadirportrolenodeA172.16.16.10/data/GreatSQL/3306PRIMARYnodeB172.16.16.11/data/GreatSQL/3306SECONDARYnodeC172.16.16.12/data/GreatSQL/3306SECONDARY先在nodeA伺服器上執行下面的初始化工作，另外兩個伺服器也照做一遍即可。
首先編輯 /etc/my.cnf 配置文件，可參考採用下面的配置參數：
#my.cnf
[mysqld]
user = mysql
port = 3306
#主從複製或MGR集群中，server_id記得要不同
#另外，實例啟動時會生成 auto.cnf，裡面的 server_uuid 值也要不同
#server_uuid的值還可以自己手動指定，只要符合uuid的格式標準就可以

執行下面的命令進行初始化：
[root@greatsql ~]# /usr/local/GreatSQL-8.0.25-15-Linux.x86_64/bin/mysqld --defaults-file=/etc/my.cnf --initialize-insecure
初始化時可選項有 --initialize 和 --initialize-insecure 兩種，前者會為root帳號生成一個隨機密碼，後者不會。在這裡為了省事，選用後者，生產環境裡請務必要為root用戶設置安全密碼。
之後就可以啟動mysqld進程了：
[root@greatsql ~]# /usr/local/GreatSQL-8.0.25-15-Linux.x86_64/bin/mysqld --defaults-file=/etc/my.cnf &
GreatSQL是基於Percona Server的分支版本，默認情況下需要用到jemalloc這個庫，如果啟動過程中報告類似下面的錯誤，只需要再安裝jemalloc或者libaio等相關的軟體包即可：
/usr/local/GreatSQL-8.0.25-15/bin/mysqld: error while loading shared libraries: libjemalloc.so.1: cannot open shared object file: No such file or directory
補充安裝libjemalloc庫即可：
[root@greatsql ~]# yum install -y jemalloc jemalloc-devel
如果想要關閉mysqld進程，執行下面的命令即可：
# 假設此時root還是空密碼
[root@greatsql ~]# /usr/local/GreatSQL-8.0.25-15-Linux.x86_64/bin/mysql -uroot -S/data/GreatSQL/mysql.sock shutdown
查看版本號：
root@GreatSQL [(none)]> \s
...
Server version: 8.0.25-15 GreatSQL, Release 15, Revision 80bbf22abbd
...
這就啟動GreatSQL服務了，接下來同樣的方法，完成另外兩個伺服器上的GreatSQL初始化並啟動，然後開始構建MGR集群。
另外，也可以參考這篇指南"將GreatSQL添加到系統systemd服務"，把GreatSQL加入系統systemd服務中。
4、搭建MGR集群MGR集群的部署可以自己手動一步步操作，也可通過MySQL Shell快速完成，分別參考下面的文檔即可：
