CentOS 上 编译MySQL-5.7.x 或者 MySQL-8.0 源码 及 多实例安装

摘要: 通过MySQL源码编译方式安装MySQL数据库实例

##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 &
