1.安装依赖组件
yum -y install gcc gcc-c++ pcre pcre-devel openssl openssl-devel
yum -y install zlib zlib-devel cmake ncurses ncurses-devel bison bison-devel
如下的几个依赖在CentOS7中需要安装,CentOS6不需要
yum -y install perl perl-devel autoconf

2.下载解压源码包(包括boost)
tar xzf mysql-boost-5.7.26.tar.gz

3.第一次安装需要添加MySQL用户
useradd -s /sbin/nologin -M mysql

4.从MySQL 5.7.5开始Boost库是必需的,编译比较耗内存和时间，内存要求至少一个G
cmake . -DCMAKE_INSTALL_PREFIX=/usr/local/mysql \
-DMYSQL_DATADIR=/data/mysql/3306 \
-DSYSCONFDIR=/etc \
-DWITH_INNOBASE_STORAGE_ENGINE=1 \
-DWITH_PARTITION_STORAGE_ENGINE=1 \
-DWITH_FEDERATED_STORAGE_ENGINE=1 \
-DWITH_BLACKHOLE_STORAGE_ENGINE=1 \
-DWITH_MYISAM_STORAGE_ENGINE=1 \
-DWITH_ARCHIVE_STORAGE_ENGINE=1 \
-DMYSQL_UNIX_ADDR=/tmp/mysql3306.sock \
-DMYSQL_TCP_PORT=3306 \
-DENABLED_LOCAL_INFILE=1 \
-DEXTRA_CHARSETS=all \
-DDEFAULT_CHARSET=utf8mb4 \
-DDEFAULT_COLLATION=utf8mb4_general_ci \
-DMYSQL_USER=mysql \
-DWITH_BINLOG_PREALLOC=ON \
-DWITH_BOOST=boost \
-DWITH_DEBUG=1

5.创建简易 /etc/my.cnf 后续补充
[client]
no-auto-rehash
default-character-set=utf8mb4
#password = your_password
port = 3306
socket = /tmp/mysql3306.sock

    [mysqld]
    character-set-server=utf8mb4
    collation-server=utf8mb4_general_ci
    basedir=/usr/local/mysql/
    datadir=/data/mysql/3306/
    socket=/tmp/mysql3306.sock

    server-id = 1102200
    log-bin=mysql_binlog
    binlog_format=row
    log_slave_updates = 1

    skip_name_resolve = ON
    innodb_file_per_table = ON
    lower_case_table_names=1 
    max_allowed_packet = 1M
    table_open_cache = 512
    sort_buffer_size = 2M
    read_buffer_size = 2M
    read_rnd_buffer_size = 8M

    [mysqld_safe]
    log-error=/data/mysql/3306/mysqld.log
    pid-file=/data/mysql/3306/mysqld.pid

    [mysqldump]
    quick
    max_allowed_packet = 16M

    [mysqlhotcopy]
    interactive-timeout

6.加入守护进程
cd /usr/local/mysql
cp support-files/mysql.server /etc/init.d/mysqld
chmod a+x /etc/init.d/mysqld
chkconfig --add mysqld
chkconfig --list mysqld
chkconfig mysqld on
7.初始化数据库， –initialize 表示默认生成一个安全的密码，–initialize-insecure 表示不生成密码
mysqld --initialize-insecure --user=mysql --basedir=/usr/local/mysql --datadir=/data/mysql/3306/
2019-07-15T03:46:38.859798Z 0 [Warning] TIMESTAMP with implicit DEFAULT value is deprecated. Please use --explicit_defaults_for_timestamp server option (see documentation for more details).

2019-07-15T03:46:39.486976Z 1 [Warning] root@localhost is created with an empty password ! Please consider switching off the --initialize-insecure option.

8.启动服务
service mysqld start
Starting MySQL.Logging to '/data/mysql/3306/mysqld.log'.
SUCCESS!
9.第一次登陆不需要密码，回车即可
mysql -u root -p
set password for root@localhost = password('root'); #修改密码

10.gdb
cat debug.file
break main #打断点
run --defaults-file=/etc/my.cnf --user=mysql --gdb #调试
chown mysql.mysql debug.file
11.启动调试环境

        gdb -x /data/mysql/3306/debug.file /usr/local/mysql/bin/mysqld
