近期MySQL发布了8.0.40版本，与之前的版本相比，部分依赖包发生了变化，因此重新编译一版，也便于大家参考。
1. 下载源码
选择对应的版本、选择源码、操作系统
如果没有登录或者没有MySQL官网账号，可以选择只下载
2. 进行编译
上传至机器，解压源码
tar -zxvf mysql-boost-8.0.40.tar.gz
2.1 准备阶段
因为编译安装需要cmake、make等命令，因此需提前安装相关依赖包及命令
yum install cmake make gcc gcc-c++ autoconf bison automake \
openssl openssl-devel zlib* fiex* libxml* \
ncurses-devel libmcrypt* libtool-ltdl-devel* -y
yum install gcc-toolset-12-gcc gcc-toolset-12-gcc-c++ gcc-toolset-12-binu由于MySQL从8.0.16版本开始，要求cmake的版本是cmake3以上，gcc版本为gcc 11.*以上版本，而且MySQL8.0.40的gcc需要12.*版本，因此如果使用Centos7等较低版本的操作系统，cmake及gcc g++版本较低，需要升级后才能编译。相关包升级附在文末
创建相关目录
mkdir /usr/local/mysql mkdir -p /data/mysql/mysql3306/{data,logs,tmp,etc}2.2 编译检查阶段
开始编译
cmake -DINSTALL_PREFIX=/usr/local/mysql \
-DMYSQL_DATADIR=/data/mysql/mysql3306/data \
-DMYSQL_UNIX_ADDR=/data/mysql/mysql3306/tmp/mysql.sock \

-DDEFAULT_COLLATION=utf8mb4_unicode_ci \
-DWITH_BOOST=/usr/local/mysql-8.0.40/boost/boost_1_77_0 \
-DENABLE_DOWNLOADS=1出现报错

CMake Error at CMakeLists.txt:642 (MESSAGE):Please do not build in-source.

-DFORCE_INSOURCE_BUILD=1出现如下新报错信息
CMake Error at cmake/readline.cmake:93 (MESSAGE):Curses library not found. Please install appropriate package,remove CMakeCache.txt and rerun cmake.On Debian/Ubuntu, package name is libncurses5-dev, on Redhat and derivates it is ncurses-devel.

缺少ncurses-devel依赖包所致，按照提示进行安装
yum install -y ncurses-devel*再次编译出现新错误
缺少依赖，继续补充
yum install libtirpc* -y安装后依旧报错（因为我的操作系统yum安装时没有libtirpc-devel），因此我选择查询出源码里的rpc.h文件，直接软连接到 /usr/include/ ，不建议这么操作，如果可以下载对应的安装包，建议安装依赖包
find / -name rpc.h
/usr/local/mysql-8.0.40/extra/libevent/libevent-2.1.11-stable/include/event2/rpc.h
/usr/local/mysql-8.0.40/extra/tirpc/libtirpc-1.3.5/tirpc/rpc/rpc.h
/usr/local/mysql-8.0.40/plugin/group_replication/libmysqlgcs/src/bindings/xcom/xcom/windeps/sunrpc/rpc/rpc.h
ln -s /usr/local/mysql-8.0.40/extra/tirpc/libtirpc-1.3.5/tirpc/rpc/rpc.h /usr/include/rpc/rpc.h
效果确实有效，继续进行编译，出现新问题：
CMake Warning at cmake/rpc.cmake:30 (MESSAGE):Cannot find rpcgen executable. You need to install the required packages:Debian/Ubuntu: apt install rpcsvc-protoRedHat/Fedora/Oracle Linux: yum install rpcgenSuSE: zypper install glibc-develCall Stack (most recent call first):plugin/group_replication/libmysqlgcs/cmake/rpcgen.cmake:113 (WARN_MISSING_RPCGEN_EXECUTABLE)plugin/group_replication/libmysqlgcs/CMakeLists.txt:51 (INCLUDE)CMake Error at plugin/group_replication/libmysqlgcs/cmake/rpcgen.cmake:114 (MESSAGE):Could not find rpcgen
Call Stack (most recent call first):plugin/group_replication/libmysqlgcs/CMakeLists.txt:51 (INCLUDE)继续安装依赖包
yum install glibc-devel rpcgen -y直至build完成
2.3 进行编译及安装
开始make进行编译，为了加快点速度，我启用2个核心进行编译
make -j 2
编译过程中出现新问题
/usr/include/rpc/rpc.h:38:10: fatal error: rpc/types.h: No such file or directory38 | #include <rpc/types.h> /* some typedefs */| ^~~~~~~~~~~~~
compilation terminated.
make[2]: *** [plugin/group_replication/libmysqlgcs/CMakeFiles/mysqlgcs.dir/build.make:99: plugin/group_replication/libmysqlgcs/CMakeFiles/mysqlgcs.dir/src/bindings/xcom/xcom/pax_msg.cc.o] Error 1

make[1]: *** Waiting for unfinished jobs....
[ 14%] Built target oci_common_objlib
make: *** [Makefile:166: all] Error 2
主要是前面的rpc依赖处理所致，因此将rpc目录下所有文件都拷贝进来
cp -rp /usr/local/mysql-8.0.40/extra/tirpc/libtirpc-1.3.5/tirpc/rpc /usr/include/rpc
In file included from /usr/include/rpc/rpc.h:38,from /usr/local/mysql-8.0.40/plugin/group_replication/libmysqlgcs/src/bindings/xcom/xcom/pax_msg.cc:28:

继续复制依赖文件
cp -rp /usr/local/mysql-8.0.40/extra/tirpc/libtirpc-1.3.5/tirpc/netconfig.h /usr/include/
完成后顺利进行编译。出现如下信息：
继续进行make install
make install完成后结果如下
编译后MySQL内容如下
3. 安装数据库
创建数据库相关目录及配置文件
mkdir -p /data/mysql/mysql3306/{data,logs,tmp,etc}配置文件按需添加放在etc/my.cnf中
创建mysql用户并将数据库目录授权
useradd mysql
chown -R mysql:mysql /data/mysql/初始化数据库
cd /usr/local/mysql
bin/mysqld --defaults-file=/data/mysql/mysql3306/etc/my.cnf --initialize --user=mysql如果无异常，则在数据库日志中可以查看初始化的root@localhost账号密码
登录数据库并修改密码
4. 补充部分依赖安装问题
4.1 cmake3
centos7系统中cmake预装版本较低，而编译8.0.40时需要更cmake3版本，如果无法通过yum install安装时，需要自己下载安装包进行安装
例如我在Centos7系统上用的3.15.5版本，可以通过如下命令下载
wget https://down.24kplus.com/linux/cmake/cmake-3.15.5.tar.gz再解压、编译、安装即可
wget https://down.24kplus.com/linux/cmake/cmake-3.15.5.tar.gztar -zxvf cmake-3.15.5.tar.gz cd cmake-3.15.5./bootstrap --prefix=/usr --datadir=share/cmake --docdir=doc/cmake && makemake install完成后检查cmake版本
4.2 gcc
对于gcc版本，MySQL8.0.40之前gcc11即可，8.0.40版本开始需要gcc12,如果可以yum方式直接安装比较方便，如果不能则需要临时调整到高版本yum源进行安装或下载安装包进行安装。本次使用的调整yum源的方式，步骤如下：
yum install scl-utils
yum install centos-release-scl centos-release-scl-rh修改配置文件
vim /etc/yum.repos.d/CentOS-SCLo-scl.repo添加如下内容

yum clean all
yum makecache安装gcc g++
yum install devtoolset-11-gcc devtoolset-11-gcc-c++ devtoolset-11-binutils -y4.3 libtirpc-devel
由于在Roky9上直接yum方式无libtirpc-devel包，因此手动下载安装包进行安装。需要用和libtirpc版本一致的，如果不一致，则缺少依赖。因此我直接将2个包都下载并安装
wget http://rpmfind.net/linux/centos-stream/9-stream/BaseOS/x86_64/os/Packages/libtirpc-1.3.3-9.el9.x86_64.rpm
wget https://mirrors.tuna.tsinghua.edu.cn/centos-stream/9-stream/CRB/x86_64/os/Packages/libtirpc-devel-1.3.3-6.el9.x86_64.rpm再本地安装yum localinstall libtirpc-1.3.3-9.el9.x86_64.rpm
yum localinstall -y libtirpc-devel-1.3.3-9.el9.x86_64.rpm4.4 重新构建及编译
由于我在构建和编译过程中有的包不存在或版本不对应，因此进行过一次重编译，及cmake时添加fresh选项
cmake --fresh -DINSTALL_PREFIX=/usr/local/mysql \
-DMYSQL_DATADIR=/data/mysql/mysql3306/data \
-DMYSQL_UNIX_ADDR=/data/mysql/mysql3306/tmp/mysql.sock \
