Mysql的8.0版本出来已经有一段时间了,近期研究下,第一步就是安装部署,以下是源码安装过程。

一、环境准备

OS:CentOS 7.4
DB:Mysql 8.0.18
硬件:40G以上空间,4G以上内存

二、安装配置

1、下载文件

下载mysql-boost-8.0.18.tar.gz

2、安装依赖包

# yum -y install gcc gcc-c++ ncurses-devel openssl-devel cmake3 bison wget bzip2
# ln -s /usr/bin/cmake3 /usr/bin/cmake

3、用户组设置

useradd mysql
groupadd mysql
mkdir -p /usr/local/mysql
mkdir -p /data/mysql8.0/log
chown -R mysql:mysql /data/mysql8.0/
chown -R mysql:mysql /usr/local/mysql

4、系统参数设置

echo -e "
kernel.sem = 250 32000 100128
kernel.sysrq = 0
net.core.rmem_max = 33554432
net.core.wmem_max = 33554432

sysctl –p


sed -i '/^GRUB_CMDLINE_LINUX/ s/\"$/  numa=off\"/g' /etc/default/grub
grub2-mkconfig -o /etc/grub2.cfg
--需要reboot
--查看dmesg | grep -i numa或cat /proc/cmdline

limit="\n*\tsoft\tnofile\t65536\n*\thard\tnofile\t65536\n*\tsoft\tnproc\t131072\n*\thard\tnproc\t131072\n*\tsoft\tstack\tunlimited\n*\thard\tstack\tunlimited"

cmake . -DCMAKE_INSTALL_PREFIX=/usr/local/mysql  -DCMAKE_CXX_COMPILER=/usr/bin/g++ -DMYSQL_DATADIR=/data/mysql8.0/datanode1 -DMYSQL_UNIX_ADDR=/data/mysql8.0/mysql.sock -DWITH_BOOST=/usr/local/boost -DSYSCONFDIR=/usr/local/mysql -DFORCE_INSOURCE_BUILD=1 -DWITH_SSL=system -DMYSQL_TCP_PORT=3306 -DENABLED_LOCAL_INFILE=1 -DDEFAULT_CHARSET=utf8mb4 -DDEFAULT_COLLATION=utf8mb4_general_ci -DWITH_EXTRA_CHARSETS=all -DFORCE_INSOURCE_BUILD=1 -DCOMPILATION_COMMENT="Kenyon's MySQL 8.0"
make && make install

--PS:可以提前下载boost_1_70_0.tar.gz放在/usr/local/boost下面,或者使用-DDOWNLOAD_BOOST=1 -DWITH_BOOST=/usr/local/boost下载

6、配置参数

[client]
port = 3306
socket = /data/mysql8.0/datanode1/mysql.sock
default-character-set = utf8mb4

[mysqld]
server-id = 99999			## 适当调整,可以选取ipv4地址

7、初始化

/usr/local/mysql/bin/mysqld --initialize --basedir=/usr/local/mysql --datadir=/data/mysql8.0/datanode1  --lower-case-table-names=1 --user=mysql

8、设置自启动

# cp /usr/local/mysql/support-files/mysql.server /etc/init.d/mysqld
# chkconfig --add mysqld
# chkconfig mysqld on

9、启动关闭

service mysqld start | stop

mysql> select version();
+-----------+
| version() |
+-----------+
| 8.0.18    |
+-----------+
1 row in set (0.00 sec)

三、问题集合

1、cmake版本过低

yum自带的cmake版本是2.x版本,mysql8源码安装要求是3.5.1以上版本,会报错如下:

[root@gp07 mysql-8.0.18]#  cmake . -DCMAKE_INSTALL_PREFIX=/usr/local/mysql -DMYSQL_DATADIR=/data/mysql8.0/data -DMYSQL_UNIX_ADDR=/data/mysql8.0/mysql.sock -DWITH_BOOST=/root/mysql-8.0.0-dmr/boost -DSYSCONFDIR=/usr/local/mysql -DWITH_SSL=system -DMYSQL_TCP_PORT=3306  -DENABLED_LOCAL_INFILE=1 -DENABLE_DTRACE=0 -DDEFAULT_CHARSET=utf8mb4 -DDEFAULT_COLLATION=utf8mb4_general_ci -DWITH_EXTRA_CHARSETS=all -DWITH_EMBEDDED_SERVER=1 -DCOMPILATION_COMMENT="Kenyon's MySQL 8.0"
-- Running cmake version 2.8.12.2
CMake Warning at CMakeLists.txt:43 (MESSAGE):
  Please use cmake3 rather than cmake on this platform


-- Please install cmake3 (yum install cmake3)
CMake Error at CMakeLists.txt:73 (CMAKE_MINIMUM_REQUIRED):
  CMake 3.5.1 or higher is required.  You are running version 2.8.12.2


-- Configuring incomplete, errors occurred!


--解决办法是用删除老的cmake版本,用新的cmake3版本替换cmake2版本
rm -f /usr/bin/cmake2
rm -f /usr/bin/cmake

yum install cmake3
ln -s /usr/bin/cmake3 /usr/bin/cmake

2、强制源码安装

-- Running cmake version 3.14.6
-- MySQL 8.0.18
-- Source directory /root/software/mysql-8.0.18
-- Binary directory /root/software/mysql-8.0.18
CMake Error at CMakeLists.txt:341 (MESSAGE):
  Please do not build in-source.  Out-of source builds are highly
  recommended: you can have multiple builds for the same source, and there is
  an easy way to do cleanup, simply remove the build directory (note that
  'make clean' or 'make distclean' does *not* work)

  You *can* force in-source build by invoking cmake with
  -DFORCE_INSOURCE_BUILD=1

根据提示,在cmake编译的时候加上-DFORCE_INSOURCE_BUILD=1参数

3、gcc版本过低

gcc要求版本是5.3或更高,实际版本是4.8.5

-- Source directory /root/software/mysql-8.0.18
-- Binary directory /root/software/mysql-8.0.18
CMake Warning at CMakeLists.txt:339 (MESSAGE):
  This is an in-source build


-- CMAKE_GENERATOR: Unix Makefiles
CMake Error at cmake/os/Linux.cmake:59 (MESSAGE):
  GCC 5.3 or newer is required (-dumpversion says 4.8.5)
Call Stack (most recent call first):
  CMakeLists.txt:442 (INCLUDE)

解决办法是升级gcc,这是个很漫长的过程

--直接安装gcc可能会=会报错,需要安装gmp、mpfr、mpc,各组件前后有关系,按此顺序执行
configure: error: Building GCC requires GMP 4.2+, MPFR 2.4.0+ and MPC 0.8.0+.
Try the --with-gmp, --with-mpfr and/or --with-mpc options to specify

wget ftp://ftp.gnu.org/gnu/mpc/mpc-1.1.0.tar.gz     -P /usr/local/src
wget ftp://ftp.gnu.org/gnu/gmp/gmp-6.1.2.tar.bz2    -P /usr/local/src
wget http://ftp.gnu.org/gnu/mpfr/mpfr-4.0.2.tar.gz  -P /usr/local/src
wget http://ftp.gnu.org/gnu/m4/m4-1.4.18.tar.gz     -P /usr/local/src
wget http://ftp.gnu.org/gnu/gcc/gcc-9.2.0/gcc-9.2.0.tar.gz -P /usr/local/src

tar -zxvf mpc-1.1.0.tar.gz
tar -zxvf mpfr-4.0.2.tar.gz
tar -jxvf gmp-6.1.2.tar.bz2
tar -zxvf m4-1.4.18.tar.gz
tar -zxvf gcc-9.2.0.tar.gz

--解压gmp需要yum install bzip2 -y

mkdir -p /usr/local/m4-1.4.18
mkdir -p /usr/local/gmp-6.1.2
mkdir -p /usr/local/mpfr-4.0.2
mkdir -p /usr/local/mpc-1.1.0
mkdir -p /usr/local/gcc-9.2.0

cd m4-1.4.18
./configure --prefix=/usr/local/m4-1.4.18
make && make install
ln -s /usr/local/m4-1.4.18/bin/m4 /usr/bin/m4

cd  gmp-6.1.2
./configure --prefix=/usr/local/gmp-6.1.2 
make && make install

cd mpfr-4.0.2
./configure --prefix=/usr/local/mpfr-4.0.2/ --with-gmp=/usr/local/gmp-6.1.2/
make && make install

cd mpc-1.1.0
./configure --prefix=/usr/local/mpc-1.1.0 --with-gmp=/usr/local/gmp-6.1.2/ --with-mpfr=/usr/local/mpfr-4.0.2/
make && make install

[root@kenyon ]# more /etc/ld.so.conf

make && make install
--编译好久....3个小时左右....

mv /usr/bin/gcc /usr/bin/gcc4.8.5
mv /usr/bin/g++ /usr/bin/g++4.8.5

ln -s /usr/local/gcc-9.2.0/bin/gcc /usr/bin/gcc
ln -s /usr/local/gcc-9.2.0/bin/g++ /usr/bin/g++

4、编译参数问题

c++: error: unrecognized command line option ‘-std=c++14’

解决办法是编译时添加  -DCMAKE_CXX_COMPILER=/usr/bin/g++

5、动态库问题

../runtime_output_directory/uca9dump: /lib64/libstdc++.so.6: version `CXXABI_1.3.9' not found (required by ../runtime_output_directory/uca9dump)

原因是升级了gcc,却没有将升级后的gcc的动态库去替换老版本的gcc动态库所致
解决办法:
cp /usr/local/src/gcc-9.2.0/x86_64-pc-linux-gnu/libstdc++-v3/src/.libs/libstdc++.so.6.0.27 /usr/lib64
cd /usr/lib64
ln -s libstdc++.so.6.0.27 libstdc++.so.6

6、源码syscall问题

在函数‘void buf_pool_create(buf_pool_t*, ulint, ulint, std::mutex*, dberr_t&)’中: /root/mysql-8.0.17/storage/innobase/buf/buf0buf.cc:1220:44: 错误:‘SYS_gettid’在此作用域中尚未声明 setpriority(PRIO_PROCESS, (pid_t)syscall(SYS_gettid), -20);

解决办法:在源文件storage/innobase/buf/buf0buf.cc的开头添加: #include "sys/syscall.h"

7、swap_lint问题

a.
/root/mysql-8.0.18/storage/innobase/lock/lock0lock.cc:1359:9: error: ‘os_compare_and_swap_thread_id’ was not declared in this scope; did you mean ‘os_compare_and_swap_uint64’

解决办法:替换源文件lock0lock.cc中os_compare_and_swap_thread_id为os_compare_and_swap_lint

b.
/root/mysql-8.0.18/storage/innobase/trx/trx0trx.cc: In function ‘void trx_init(trx_t*)’:
/root/mysql-8.0.18/storage/innobase/trx/trx0trx.cc:222:5: error: ‘os_compare_and_swap_thread_id’ was not declared in this scope; did you mean ‘os_compare_and_swap_lint’?
  222 |     os_compare_and_swap_thread_id(&trx->killed_by, thread_id, 0);
      |     ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~
      |     os_compare_and_swap_lint
/root/mysql-8.0.18/storage/innobase/trx/trx0trx.cc: In function ‘void trx_kill_blocking(trx_t*)’:
/root/mysql-8.0.18/storage/innobase/trx/trx0trx.cc:3230:5: error: ‘os_compare_and_swap_thread_id’ was not declared in this scope; did you mean ‘os_compare_and_swap_lint’?
 3230 |     os_compare_and_swap_thread_id(&victim_trx->killed_by, thread_id, 0);

解决办法:
修改storage/innobase/trx/trx0trx.cc中替换os_compare_and_swap_thread_id为os_compare_and_swap_lint,注意有两处修改

8、初始化失败

2019-12-02T11:31:16.760733+08:00 0 [System] [MY-010116] [Server] /usr/local/mysql/bin/mysqld (mysqld 8.0.18) starting as process 10686
2019-12-02T11:31:16.776210+08:00 1 [ERROR] [MY-011011] [Server] Failed to find valid data directory.
2019-12-02T11:31:16.776500+08:00 0 [ERROR] [MY-010020] [Server] Data Dictionary initialization failed.
2019-12-02T11:31:16.776570+08:00 0 [ERROR] [MY-010119] [Server] Aborting
2019-12-02T11:31:16.777890+08:00 0 [System] [MY-010910] [Server] /usr/local/mysql/bin/mysqld: Shutdown complete (mysqld 8.0.18)  Kenyon's MySQL 8.0.18

解决办法:
在以上问题都处理掉后,重新cmake、make和make install

四、总结

1、mysql8版本源码安装较以前的7版本要求更高,尤其是编译器的要求更高,编译时间也更长
2、以前低版本(5.7以前)可以定制化各种引擎和初始化参数,新版本已经默认安装,不再需要编译该类参数
3、官方目前不推荐进行源码编译,从时间成本上来看,建议还是选择rpm安装,也可以自己编译完成后打包rpm自行安装
4、目前发现的一个坑是想设置大小写敏感需要在初始化数据库时就要指定(initialize --lower-case-table-names=1),否则只能导出重新初始化
5、初始化完成后密码会打印在屏幕日志末尾,首次登陆必须先改密码才能使用
