MySQL 8.0源码编译

提示下，编译MySQL 8.0版本，需要gcc版本5.3.0以上才行。我这次的编译环境是ubuntu 18.04，其gcc版本是7.4。

首先，下载带boost代码的MySQL源码包，在官网下载页面有相应的提示：

解压缩后，就可以开始编译了。首先，指定编译的选项：

[root@ubuntu]# cd /opt/src/mysql-8.0.17/
cmake . \
-DWITH_BOOST=/opt/mysql-8.0.17/boost/ \
-DCMAKE_INSTALL_PREFIX=/usr/local/mysql-8.0.17 \
-DMYSQL_DATADIR=/data/mysql \
-DWITHOUT_CSV_STORAGE_ENGINE=1 \
-DWITHOUT_BLACKHOLD_STORAGE_ENGINE=1 \
-DWITHOUT_FEDERATED_STORAGE_ENGINE=1 \
-DWITHOUT_ARCHIVE_STORAGE_ENGINE=1 \
-DWITHOUT_NDBCLUSTER_STORAGE_ENGINE=1 \
-DFORCE_INSOURCE_BUILD=1 \
-DCMAKE_CXX_COMPILER=/usr/local/bin/g++ \
-DCMAKE_C_COMPILER=/usr/local/bin/gcc

在上面的参数中，我把不常用的引擎直接给禁用了，读者们若有需要个别引擎可自行删除对应选项即可。而DEBUG、SSL等几个选项则建议不要禁用。 …

接下来就是执行 make && make install ，顺利的话就完成编译并安装了。如果编译错误，则删除CMakeCache.txt文件后解决对应错误，重新编译即可。

编译完后看到的MySQL版本号就是这样的了：

[root@ubuntu]# /usr/local/mysql-8.0.17/bin/mysqld --verbose -V
/usr/local/mysql-8.0.17/bin/mysqld  Ver 8.0.17 for Linux on x86_64 (Source distribution)

有没有感觉有点酷酷的，嘿。

添加mysql用户 ：

shell> groupadd mysql8
shell> useradd -r -g mysql8 -s /bin/false mysql8

初始化数据：

sudo /usr/local/mysql-8.0.17/bin/mysqld --defaults-file=/etc/mysql/mysql8.conf.d/mysqld.cnf --pid-file=/var/run/mysqld8/mysqld.pid --initialize-insecure --user=mysql8

#使用时--initialize-insecure，不会root生成密码.  使用--initialize了 “ 默认安全 ”安装（即包括生成随机初始的 root密码）。在这种情况下，密码标记为已过期，您需要选择一个新密码。

启动mysql

sudo /usr/local/mysql-8.0.17/bin/mysqld --defaults-file=/etc/mysql/mysql8.conf.d/mysqld.cnf --daemonize --pid-file=/var/run/mysqld8/mysqld.pid

附 mysql 8.0 的my.cnf配置

#
# The MySQL database server configuration file.
#
# You can copy this to one of:
# - "/etc/mysql/my.cnf" to set global options,
# - "~/.my.cnf" to set user-specific options.
# 
# One can use all long options that the program supports.
# Run program with --help to get a list of available options and with
# --print-defaults to see which it would actually understand and use.
#
# For explanations see
# http://dev.mysql.com/doc/mysql/en/server-system-variables.html

# This will be passed to all mysql clients
# It has been reported that passwords should be enclosed with ticks/quotes
# escpecially if they contain "#" chars...
