mysql-5.7.23源码编译安装

1.下载源码

# wget https://cdn.mysql.com//Downloads/MySQL-5.7/mysql-5.7.23.tar.gz
# tar xf mysql-5.7.23.tar.gz

2.隐藏版本信息

隐藏版本信息是XX电信运营商提出的变态要求，经测试版本信息不能直接删除，否则编译出错，暂时修改为100.100.100

# cd mysql-5.7.23
# vim VERSION
MYSQL_VERSION_MAJOR=100
MYSQL_VERSION_MINOR=100
MYSQL_VERSION_PATCH=100
MYSQL_VERSION_EXTRA=

版本高于5.8版本报错

#error "show_compatibility_56 is to be removed in MySQL 5.8"

解决办法：

修改sql/mysqld.cc源代码，将下面的内容（346-352行）

#if MYSQL_VERSION_ID >= 50800
#error "show_compatibility_56 is to be removed in MySQL 5.8"
#else
/*
  Default value TRUE for the EMBEDDED_LIBRARY,
  default value from Sys_show_compatibility_56 otherwise.
*/
my_bool show_compatibility_56= TRUE;
#endif /* MYSQL_VERSION_ID >= 50800 */

修改为

//#if MYSQL_VERSION_ID >= 50800
//#error "show_compatibility_56 is to be removed in MySQL 5.8"
//#else
/*
  Default value TRUE for the EMBEDDED_LIBRARY,
  default value from Sys_show_compatibility_56 otherwise.
*/
my_bool show_compatibility_56= TRUE;
//#endif /* MYSQL_VERSION_ID >= 50800 */

然后重新编译即可。

3.下载编译需要的软件

# yum -y install gcc gcc-c++ cmake ncurses-devel bsion

4.编译mysql

编译过程中需要用到boost_1_59_0，因为没有安装，所以加上-DDOWNLOAD_BOOST=1 -DWITH_BOOST=/usr/local

# cmake -DDOWNLOAD_BOOST=1   -DWITH_BOOST=/usr/local   -DCMAKE_INSTALL_PREFIX=/usr/local/mysql   -DMYSQL_UNIX_ADDR=/usr/local/mysql/mysql.sock   -DDEFAULT_CHARSET=utf8   -DDEFAULT_COLLATION=utf8_general_ci   -DWITH_MYISAM_STORAGE_ENGINE=1   -DWITH_INNOBASE_STORAGE_ENGINE=1   -DENABLED_LOCAL_INFILE=1   -DMYSQL_DATADIR=/usr/local/mysql/data   -DMYSQL_TCP_PORT=3306

# make && make install

5.安装mysql

创建mysql用户和组
# groupadd -g 306 mysql
不需要登录也不需要创建家目录
# useradd -u 306 -g 306 -s /bin/false -M mysql 
# chown -R mysql:mysql /usr/local/mysql

初始化
# cd /usr/local/mysql
# ./bin/mysqld --initialize --user=mysql --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data 2>&1 | tee data/mysql_init.log
提示：启动时会生成初始密码，记得查看，忘记了可以查看文件data/mysql_init.log
设置开机启动
# cp support-files/mysql.server /etc/init.d/mysql
# chkconfig --add mysql 
# chkconfig mysql on
# service mysql start
# grep "temporary password" data/mysql_init.log

配置环境变量
# cat > /etc/profile.d/mysql.sh <<EOF
export PATH=/usr/local/mysql/bin:$PATH

# source /etc/profile

6.验证mysql

# mysql -p
