1.依赖包安装
yum install gdb gcc gcc-c++ ncurses-devel cmake libaio bison zlib-devel openssl openssl-devel patch
2.下载mysql源码包和boost库
- 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
sort_buffer_size = 2M
join_buffer_size = 4M
read_buffer_size = 2M
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
max_binlog_size = 500M
binlog_format = mixed
log_output = FILE
expire_logs_days = 5
slow_query_log = 1
long_query_time = 3
slow_query_log_file = /home/mysql/log/slow-query.log
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 &
