编译安装MySQL8及常见错误处理

初稿。。。

1.下载

https://downloads.mysql.com/archives/community/

选择对应版本->选择 source code ->系统版本一定要选all ->拉至最下方-选择mysql-boost-8.0.xx.tar.gz（不下载带有boost的压缩包，需自行安装boost）

图片后续添加。

 2.解压

tar -zxf mysql-boost-8.0.25.tar.gz

3.编译安装

#预编译
cmake3 -DCMAKE_INSTALL_PREFIX=/home/apps/mysql  -DMYSQL_UNIX_ADDR=/home/apps/mysql.sock   -DEXTRA_CHARSETS=all  -DDEFAULT_CHARSET=utf8  -DDEFAULT_COLLATION=utf8_general_ci  -DWITH_MYISAM_STORAGE_ENGINE=1  -DWITH_INNOBASE_STORAGE_ENGINE=1  -DWITH_MEMORY_STORAGE_ENGINE=1  -DWITH_READLINE=1  -DENABLED_LOCAL_INFILE=1  -DCMAKE_C_COMPILER=/home/apps/gcc/bin/gcc -DCMAKE_CXX_COMPILER=/home/apps/gcc/bin/g++   -DFORCE_INSOURCE_BUILD=1  -DDOWNLOAD_BOOST=1 -DWITH_BOOST=/home/downloads/mysql/mysql-8.0.25/boost -DMYSQL_USER=mysql  -DMYSQL_TCP_PORT=3306 

#编译
make

#安装
make install

4.初始化

#配置文件/etc/my.cnf

[mysqld]
datadir=/home/data
socket=/home/apps/mysql/mysql.sock
bind-address=0.0.0.0(可根据情况修改为本机IP)
port=3306

#创建用户
useradd -s /sbin/nologin -M mysql

#初始化
cd /home/apps/mysql/bin/
./mysqld --initialize --user=mysql --basedir=/home/apps/mysql --datadir=/home/data

#启动登录并更新密码
./mysqld_safe --user=mysql
mysql -u root -p -h 127.0.0.1 -P 3306

use mysql；
select user,host from mysql;
alter user 'root'@'localhost' identified by '123456';
#添加远程登录
create user 'root'@'%' identified by '123456';
grant all privileges on *.* to 'root'@'%' with grant option;
flush privileges;

 

 

 

 

 二、常见错误

1.Please install the appropriate openssl developer package

Cannot find appropriate system libraries for WITH_SSL=system.
Make sure you have specified a supported SSL version.
Valid options are :
system (use the OS openssl library),
yes (synonym for system),
</path/to/custom/openssl/installation>

CMake Error at cmake/ssl.cmake:61 (MESSAGE):
  Please install the appropriate openssl developer package.

Call Stack (most recent call first):
  cmake/ssl.cmake:315 (FATAL_SSL_NOT_FOUND_ERROR)
  CMakeLists.txt:1344 (MYSQL_CHECK_SSL)


-- Configuring incomplete, errors occurred!

See also "/home/downloads/mysql/mysql-8.0.25/CMakeFiles/CMakeError.log".

解决方案

yum install openssl-devel

2.gcc版本过低

升级gcc
gcc下载地址
http://www.netgull.com/gcc/releases/gcc-9.3.0


依赖包下载地址
ftp://gcc.gnu.org/pub/gcc/infrastructure/

gmp-6.1.0.tar.bz2
isl-0.18.tar.bz2
mpfr-3.1.4.tar.bz2
mpc-1.0.3.tar.gz


./configure
make && make install 



tar -zxf gcc-9.3.0.tar.gz && cd gcc-9.3.0

./configure --prefix=/home/apps/gcc  --enable-bootstrap  --enable-checking=release --enable-languages=c,c++ --disable-multilib

make   
make install
#添加环境变量
vim /etc/profile
#添加下述内容
GCC_HOME=/home/apps/gcc
export PATH=$GCC_HOME/bin:$PATH
source /etc/profile

3./lib64/libstdc++.so.6: version `CXXABI_1.3.9' not found

../runtime_output_directory/uca9dump: /lib64/libstdc++.so.6: version `CXXABI_1.3.9' not found (required by ../runtime_output_directory/uca9dump)
make[2]: *** [strings/uca900_zh_tbls.cc] Error 1
make[1]: *** [strings/CMakeFiles/strings_objlib.dir/all] Error 2
make: *** [all] Error 2

解决方案

gcc升级时，新版本动态库未覆盖旧版本动态库
删除旧软连接。生成新链接

find / -name libstdc++.so.6
rm /usr/lib/libstdc++.so.6 /usr/lib64/libstdc++.so.6
ln -s /home/apps/gcc/lib64/libstdc++.so.6  /usr/lib64/libstdc++.so.6
ln -s /home/apps/gcc/lib64/libstdc++.so.6 /usr/lib/libstdc++.so.6

4.error: ‘SYS_gettid’ was not declared in this scope

In function ‘void buf_pool_create(buf_pool_t*, ulint, ulint, std::mutex*, dberr_t&)’:
/home/downloads/mysql/mysql-8.0.25/storage/innobase/buf/buf0buf.cc:1228:44: error: ‘SYS_gettid’ was not declared in this scope

解决方案

在文件buf0buf.cc的开头添加： 
#include "sys/syscall.h" 再次make

 5.error while loading shared libraries: libisl.so.15: cannot open shared object file: No such file or directory

/etc/ld.so.conf 添加如下内容
include ld.so.conf.d/*.conf
/usr/local/lib


find /usr/local/lib -name libisl.so.15

/usr/local/lib 为libisl.so.15所在目录

文件内容添加后，执行ldconfig

#查看当前动态库
ldconfig -p

解压文件脚本

#!/bin/bash

COM_DIR=$1
DECOM_DIR=$2

    ls $COM_DIR>>/tmp/filelist.txt
