1.依赖包安装

yum install gdb gcc gcc-c++ ncurses-devel cmake libaio bison zlib-devel openssl openssl-devel patch

• 下载最新MysqL源码

https://cdn.MysqL.com//Downloads/MysqL-5.7/MysqL-boost-5.7.18.tar.gz

• 下载boost库，版本 boost_1_59_0

http://sourceforge.net/projects/boost/files/boost/1.59.0/boost_1_59_0.tar.bz2

MysqL-8.0需要boost_1_63_0版本

3.上传并解压

上传并解压安装包：
[root@localhost MysqL]# tar -xzvf MysqL-boost-5.7.18.tar.gz
[root@localhost MysqL]# tar -xzvf boost_1_59_0.tar.bz2

4 建立MysqL用户和组，建立相关目录

/usr/sbin/groupadd MysqL
/usr/sbin/useradd MysqL -g MysqL -d /home/MysqL -s /sbin/nologin

mkdir /home/MysqL/data/3306/data
mkdir /home/MysqL/data/3306/log
mkdir /home/MysqL/data/3306/tmp
mkdir /home/MysqL/data/3306/binlog

三实例部署的话，可以同时创建以下目录

mkdir /home/MysqL/data/3307/data
mkdir /home/MysqL/data/3307/log
mkdir /home/MysqL/data/3307/tmp
mkdir /home/MysqL/data/3307/binlog

mkdir /home/MysqL/data/3308/data
mkdir /home/MysqL/data/3308/log
mkdir /home/MysqL/data/3308/tmp
mkdir /home/MysqL/data/3308/binlog

创建MysqL安装目录

mkdir /usr/local/MysqL
chown -R MysqL.MysqL /usr/local/MysqL
chown -R MysqL.MysqL /home/MysqL

5 编译MysqL源码&安装MysqL

生成makefile文件

cmake \
-DCMAKE_INSTALL_PREFIX=/usr/local/MysqL \
-DMysqL_DATADIR=/home/MysqL/data \
-DSYSCONFDIR=/etc \
-DWITH_MYISAM_STORAGE_ENGINE=1 \
-DWITH_INNOBASE_STORAGE_ENGINE=1 \
-DWITH_EDITLINE=bundled \
-DMysqL_UNIX_ADDR=/home/MysqL/MysqL.sock \
-DMysqL_TCP_PORT=3306 \
-DENABLED_LOCAL_INFILE=1 \
-DWITH_PARTITION_STORAGE_ENGINE=1 \
-DEXTRA_CHARSETS=all \
-DDEFAULT_CHARSET=utf8mb4 \
-DDEFAULT_COLLATION=utf8mb4_general_ci \
-DWITH_DEBUG=0  \ 
-DDOWNLOAD_BOOST=1 -DWITH_BOOST=/xxx/xxx/boost_1_59_0 -DDOWNLOAD_BOOST_TIMEOUT=60000

如果日后需要调试MysqL源码，在cmake时候设置 -DWITH_DEBUG=1，即编译为带调试信息的MysqL目标文件

编译

make

根据机器配置等待一段时间，看到100%字样，则说明编译成功

安装到 /usr/local/MysqL 目录下

make install

6.配置MysqL环境变量

在/etc/profile中添加/usr/local/MysqL/bin到PATH变量中

PATH=/usr/local/MysqL/bin:$PATH
    执行source /etc/profile 生效

7.初始化MysqL数据库

初始化data文件

MysqLd --defaults-file=/home/MysqL/data/3306/my.cnf --initialize-insecure --user=MysqL --basedir=/usr/local/MysqL --datadir=/home/MysqL/data/3306/data

切换到MysqL用户

su - MysqL

生成ssl所需文件

MysqL_ssl_rsa_setup --user=MysqL --basedir=/usr/local/MysqL --datadir=/home/MysqL/data/3306/data

启动MysqL

MysqLd --defaults-file=/home/MysqL/data/3306/my.cnf --user=MysqL 

先通过unix socket修改MysqL root用户密码

MysqL -uroot -p -S /home/MysqL/data/3306/MysqL.sock
UPDATE MysqL.user SET authentication_string = PASSWORD('MysqL') WHERE USER LIKE '%root%';
grant all privileges on *.* to 'root'@'%' identified by 'MysqL' with grant option;
flush privileges;

验证通过tcp/ip协议登陆MysqL

MysqL -h127.0.0.1 -uroot -p -P3306

8.配置数据库配置文件

cd /usr/local/MysqL/
cp support-files/my-default.cnf  /etc/my.cnf

>/etc/my.cnf
vi /etc/my.cnf
[client]
socket=/home/MysqL/MysqL.sock
[MysqLd]
symbolic-links=0
server_id                  = 120
default_storage_engine     = Innodb
user                       = MysqL
port                       = 3306
basedir                    = /usr/local/mysq
datadir                    = /home/MysqL/data
tmpdir                     = /home/MysqL/tmp
socket                     = /home/MysqL/MysqL.sock
pid_file                   = /home/MysqL/MysqL.pid

character_set_server       = utf8
collation_server           = utf8_general_ci

open_files_limit           = 10240
explicit_defaults_for_timestamp

max_allowed_packet         = 256M
max_heap_table_size        = 256M
net_buffer_length          = 8K

read_rnd_buffer_size       = 16M

log_error                  = /home/MysqL/log/error.log

log_bin                    = /home/MysqL/binlog/MysqL-bin
binlog_cache_size          = 32M
max_binlog_cache_size      = 2G

innodb_buffer_pool_size    = 500M
innodb_log_file_size       = 200M
innodb_log_files_in_group  = 3
innodb_lock_wait_timeout   = 20

[MysqL]
no_auto_rehash

[MysqLd_safe]
log-error=/home/MysqL/log/error.log

9 配置MysqL成功centos服务（可以不做）

配置MysqL系统服务：

cd /usr/local/MysqL
cp support-files/MysqL.server  /etc/init.d/MysqL
chkconfig --add MysqL
chkconfig MysqL on

启动数据库：

service MysqL start

如果想部署多实例情况，重复步骤7到8即可

我的多实例启动脚本：

MysqLd_safe --defaults-file=/home/MysqL/data/3306/my.cnf --user=MysqL &
MysqLd_safe --defaults-file=/home/MysqL/data/3307/my.cnf --user=MysqL &
MysqLd_safe --defaults-file=/home/MysqL/data/3308/my.cnf --user=MysqL &
