MySQL从源码编译安装

基于版本

CentOS-7-x86_64-Minimal-2009

mysql-boost-8.0.25.tar.gz

注：wget下载如果不稳定，可以手动下载好mysql-boost-8.0.25.tar.gz

下载地址见：https://dev.mysql.com/downloads/mysql/

新建用户和用户组

groupadd mysql
useradd -r -g mysql -s /bin/false mysql

准备必要文件夹并赋予相应的权限

# 准备必要文件夹
mkdir -p /usr/local/mysql /data/mysql/

# 赋予相应的权限
chown -R mysql.mysql /usr/local/mysql/
chown -R mysql.mysql /data/mysql/
chmod -R 755 /data/mysql/
chmod -R 755 /usr/local/mysql/

安装必要依赖

yum -y install wget gcc gcc-c++ ncurses ncurses-devel libaio-devel openssl openssl-devel git bison
yum install -y centos-release-scl-rh 
yum install -y centos-release-scl
yum install -y devtoolset-10-gcc 
yum install -y devtoolset-10-gcc-c++

执行

source /opt/rh/devtoolset-10/enable

通过wget下载cmake3，如果不稳定，可以手动下载cmake-3.20.2-Linux-x86_64.tar.gz并上传到/usr/local/src目录下

# 卸载原有的cmake
yum -y remove cmake

cd /usr/local/src
# 下载，如果不稳定，可以手动下载好并上传到/usr/local/src目录
wget https://github.com/Kitware/CMake/releases/download/v3.20.2/cmake-3.20.2-Linux-x86_64.tar.gz

解压并安装cmake3

tar -xf cmake-3.20.2-linux-x86_64.tar.gz
mv cmake-3.20.2-linux-x86_64 /usr/local/cmake

vi /etc/profile

在文件末尾加上

export CMAKE_PATH=/usr/local/cmake
export PATH=$PATH:$CMAKE_PATH/bin

然后执行

source /etc/profile

验证cmake

[root@db01 src]# cmake -version
cmake version 3.20.2

CMake suite maintained and supported by Kitware (kitware.com/cmake).

编译安装MySQL

将mysql-boost-8.0.25.tar.gz放到/usr/local/src目录下

cd /usr/local/src

# 解压
tar -xf mysql-boost-8.0.25.tar.gz

cd mysql-8.0.25/

执行cmake,注意boost的路径要修改正确

cmake . -DCMAKE_INSTALL_PREFIX=/usr/local/mysql -DMYSQL_DATADIR=/data/mysql -DSYSCONFDIR=/etc -DMYSQL_TCP_PORT=3306 -DWITH_BOOST=/usr/local/src/mysql-8.0.25/boost -DDEFAULT_CHARSET=utf8 -DDEFAULT_COLLATION=utf8_general_ci -DENABLED_LOCAL_INFILE=ON -DWITH_INNODB_MEMCACHED=ON -DWITH_INNOBASE_STORAGE_ENGINE=1 -DWITH_FEDERATED_STORAGE_ENGINE=1 -DWITH_BLACKHOLE_STORAGE_ENGINE=1 -DWITH_ARCHIVE_STORAGE_ENGINE=1 -DWITHOUT_EXAMPLE_STORAGE_ENGINE=1 -DWITH_PERFSCHEMA_STORAGE_ENGINE=1 -DFORCE_INSOURCE_BUILD=1

漫长等待后.......

如果执行无误，最后会提示

...
-- Configuring done
-- Generating done
-- Build files have been written to: /usr/local/src/mysql-8.0.25

执行make

cd /usr/local/src/mysql-8.0.25/

make

漫长等待后.......

执行make可能会报如下错误

during RTL pass: vartrack
/usr/local/src/mysql-8.0.25/sql/opt_range.cc: In function ‘TRP_RANGE* get_key_scans_params(PARAM*, SEL_TREE*, bool, bool, const Cost_estimate*)’:

Please submit a full bug report,

See <http://bugzilla.redhat.com/bugzilla> for instructions.
The bug is not reproducible, so it is likely a hardware or OS problem.
make[2]: *** [sql/CMakeFiles/sql_main.dir/opt_range.cc.o] Error 1
make[1]: *** [sql/CMakeFiles/sql_main.dir/all] Error 2
make: *** [all] Error 2

可以先忽略，重新执行

make

然后make install

make install

初始化

/usr/local/mysql/bin/mysqld --initialize-insecure --user=mysql --basedir=/usr/local/mysql --datadir=/data/mysql

修改mysql配置(可选)

cd /etc
cp my.cnf my.cnf.backup

vi /etc/my.cnf

修改成以下内容：

[client]
port=3306
socket=/tmp/mysql.sock
default-character-set=utf8
#user=root
#password=123
[mysqld]
server-id=1
#skip-grant-tables
port=3306
user=mysql
log_bin=mysql-bin
binlog_format=mixed
max_connections=200
socket=/tmp/mysql.sock
basedir=/usr/local/mysql
datadir=/data/mysql
pid-file=/data/mysql/mysql.pid
init-connect='SET NAMES utf8'
character-set-server=utf8
default-storage-engine=INNODB
log_error=/data/mysql/mysql-error.log
slow_query_log_file=/data/mysql/mysql-slow.log
[mysqldump]
quick
max_allowed_packet=16M

配置环境变量和启动脚本

环境变量

echo "PATH=/usr/local/mysql/bin:$PATH" >> /etc/profile

source /etc/profile

启动脚本

cp /usr/local/src/mysql-8.0.25/support-files/mysql.server /etc/init.d/mysqld

chmod +x /etc/init.d/mysqld

启动

service mysqld restart

登录

mysql -u root -p

按回车，即可无密码登录

如果想配置root的密码，可以在无密码登录后执行：

# 创建一个用户，用户名/密码：young/0320
create user 'young'@'%' identified by '0320';

# 赋予权限
grant all privileges on *.* to 'young'@'%';

flush privileges;

增加到开机启动

chkconfig --level 345 mysqld on

测试是否开机启动,执行reboot

reboot

重启完毕后

ps -ef|grep mysqld

显示mysql已经启动了

root       1094      1  0 12:57 ?        00:00:00 /bin/sh /usr/local/mysql/bin/mysqld_safe --datadir=/data/mysql --pid-file=/data/mysql/mysql.pid
mysql      1452   1094  9 12:57 ?        00:00:00 /usr/local/mysql/bin/mysqld --basedir=/usr/local/mysql --datadir=/data/mysql --plugin-dir=/usr/local/mysql/lib/plugin --user=mysql --log-error=/data/mysql/mysql-error.log --pid-file=/data/mysql/mysql.pid --socket=/tmp/mysql.sock --port=3306

卸载

如果要完全卸载Linux，可以通过如下的方式：

停止服务

service mysqld stop

然后执行

find / -name mysql

找到所有mysql相关的文件夹

/run/lock/subsys/mysql
/etc/selinux/targeted/active/modules/100/mysql
/usr/lib64/mysql
/usr/share/mysql
/usr/local/src/mysql-8.0.25/include/mysql
/usr/local/src/mysql-8.0.25/plugin/group_replication/libmysqlgcs/include/mysql
/usr/local/src/mysql-8.0.25/router/src/harness/include/mysql
/usr/local/src/mysql-8.0.25/router/src/harness/include/CMakeFiles/harness_net_ts.dir/mysql
/usr/local/src/mysql-8.0.25/router/include/mysql
/usr/local/src/mysql-8.0.25/runtime_output_directory/mysql
/usr/local/mysql
/usr/local/mysql/include/mysql
/usr/local/mysql/bin/mysql
/data/mysql
/data/mysql/mysql

然后执行 rm -rf 删掉这些文件即可。

当然你确保

find / -name mysql

出来的文件没有需要保留的文件，也可以执行

rm -rf `find / -name mysql`

批量删除
