mysql源码编译安装_MySQL5.7.26 源码编译安装

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

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).

2019-07-15T03:46:39.250281Z 0 [Warning] InnoDB: New log files created, LSN=45790

2019-07-15T03:46:39.410341Z 0 [Warning] InnoDB: Creating foreign key constraint system tables.

2019-07-15T03:46:39.483526Z 0 [Warning] No existing UUID has been found, so we assume that this is the first time that this server has been started. Generating a new UUID: 26fabfb6-a6b3-11e9-8f70-fa163efdf571.

2019-07-15T03:46:39.485233Z 0 [Warning] Gtid table is not ready to be used. Table 'mysql.gtid_executed' cannot be opened.

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
