Mysql 8.0 源码编译 多实例安装

https://blog.csdn.net/cuilouyi9469/article/details/100438142

一、准备工作

1. 下载安装包

路径：https://dev.mysql.com/downloads/mysql/

这里选择 mysq-8.0.16.tar.gz

2. 清理已有版本

##查询

rpm -qa | grep mysql rpm -qa | grep maria ##清理(如果存在的话)

yum remove mysql ##或者

yum remove mariadb 3. 安装依赖包

(1)常规依赖

yum -y install gcc gcc-c++ ncurses ncurses-devel libaio-devel openssl openssl-devel

(2)特殊版本的依赖

编译的时候，分别错误提示：

                    CMake 3.4.3 or higher is required.

                    GCC 5.3 or newer is required

所以需要安装Cmake和GCC的相关版本

二、编译安装（软件）

1. 解压安装包

tar -zxvf tar -zxvf mysql-8.0.16.tar.gz 2. cmake配置

(1) 进入目录 mysql-8.0.16 ,建立一个目录，用于存放编译好的软件

cd mysql-8.0.16 mkdir xiaochong (2) 进入子目录xiaochong，进行编译前的配置。 主要cmake后是 . . , 执行其父目录。

cd xiaochong 配置参数：

cmake .. -DCMAKE_INSTALL_PREFIX=/usr/local/mysql
-DDEFAULT_CHARSET=utf8
-DDEFAULT_COLLATION=utf8_general_ci
-DENABLED_LOCAL_INFILE=ON
-DWITH_INNODB_MEMCACHED=ON
-DWITH_SSL=system
-DWITH_INNOBASE_STORAGE_ENGINE=1
-DWITH_FEDERATED_STORAGE_ENGINE=1
-DWITH_BLACKHOLE_STORAGE_ENGINE=1
-DWITH_ARCHIVE_STORAGE_ENGINE=1
-DWITHOUT_EXAMPLE_STORAGE_ENGINE=1
-DWITH_PERFSCHEMA_STORAGE_ENGINE=1
-DCOMPILATION_COMMENT="xiaochong edition"
-DDOWNLOAD_BOOST=1
-DWITH_BOOST=/usr/local/boost
-DCMAKE_CXX_COMPILER=/usr/bin/g++
-DWITH_BOOST=/tmp 3. 编译

make -j 10 4 . 安装

make install 末尾如下提示，表示成功。

-- Configuring done

-- Generating done

-- Build files have been written to: /software/mysql-8.0.16/xiaochong

---

错误1 c++: error: unrecognized command line option ‘-std=c++14’

解决方式： 添加： -DCMAKE_CXX_COMPILER=/usr/bin/g++

三、创建数据库

1、创建用户

groupadd mysql useradd -g mysql mysql 2. 创建相关目录

mkdir -p /data/mysql/{3306,3307}/{data,log,tmp,innodb,innodb_log} 这里是两个实例的目录，分别是3306和3307.

创建后，目录结构如下：

[root@mysql80 /]# cd data

[mysql@mysql80 data]$ tree .

.

└── mysql

├── 3306

│ ├── data

│ ├── innodb

│ ├── innodb_log

│ ├── log

│ └── tmp

└── 3307

├── data

├── innodb

├── innodb_log

├── log

└── tmp

3. 修改目录权限

chown -R mysql:mysql /data/mysql/ chown -R mysql:mysql /usr/local/mysql/ 4. 添加环境变量

echo 'export PATH=$PATH:/usr/local/mysql/bin' >> /etc/profile source /etc/profile 5. 添加配置文件

（1）3306

vim /data/mysql/3306/my3306.cnf 内容如下：

[client] port=3306 socket=/data/mysql/3306/mysql.sock [mysqld] port=3306 user=mysql socket=/data/mysql/3306/mysql.sock pid-file=/data/mysql/3306/mysql.pid basedir=/usr/local/mysql datadir=/data/mysql/3306/data tmpdir=/data/mysql/3306/tmp open_files_limit=60000 #explicit_defaults_for_timestamp server-id=3306 lower_case_table_names=1 character-set-server=utf8 #federated #sql_mode=STRICT_TRANS_TABLES max_connections=1000 max_connect_errors=100000 interactive_timeout=86400 wait_timeout=86400 sync_binlog=0 back_log=100 default-storage-engine=InnoDB log_slave_updates=1 #*********** Logs related settings *********** log-bin=/data/mysql/3306/log/mysql3306-bin binlog_format=mixed binlog_cache_size=32m max_binlog_cache_size=64m max_binlog_size=512m long_query_time=1 log_output=FILE log-error=/data/mysql/3306/log/mysql-error.log slow_query_log=1 slow_query_log_file=/data/mysql/3306/log/slow_statement.log #log_queries_not_using_indexes general_log=0 general_log_file=/data/mysql/3306/log/general_statement.log #expire-logs-days = 14 binlog_expire_logs_seconds=1728000 relay-log=/data/mysql/3306/log/relay-bin relay-log-index=/data/mysql/3306/log/relay-bin.index #****** MySQL Replication New Feature********* master-info-repository=TABLE relay-log-info-repository=TABLE #relay-log-recovery #*********** INNODB Specific options *********** innodb_buffer_pool_size=2048M transaction-isolation=REPEATABLE-READ innodb_buffer_pool_instances=8 innodb_file_per_table=1 innodb_data_home_dir=/data/mysql/3306/innodb innodb_data_file_path=ibdata1:2048M:autoextend innodb_thread_concurrency=8 innodb_log_buffer_size=16M innodb_log_file_size=128M innodb_log_files_in_group=3 innodb_log_group_home_dir=/data/mysql/3306/innodb_log innodb_flush_log_at_trx_commit=2 innodb_max_dirty_pages_pct=70 innodb_flush_method=O_DIRECT [mysql] no-auto-rehash default-character-set=gbk prompt = (\u@\h) [\d]>_ （1）3307

vim /data/mysql/3307/my3307.cnf 内容如下：

[client] port=3307 socket=/data/mysql/3307/mysql.sock [mysqld] port=3307 user=mysql socket=/data/mysql/3307/mysql.sock pid-file=/data/mysql/3307/mysql.pid basedir=/usr/local/mysql datadir=/data/mysql/3307/data tmpdir=/data/mysql/3307/tmp open_files_limit=60000 #explicit_defaults_for_timestamp server-id=3307 lower_case_table_names=1 character-set-server=utf8 #federated #sql_mode=STRICT_TRANS_TABLES max_connections=1000 max_connect_errors=100000 interactive_timeout=86400 wait_timeout=86400 sync_binlog=0 back_log=100 default-storage-engine=InnoDB log_slave_updates=1 #*********** Logs related settings *********** log-bin=/data/mysql/3307/log/mysql3306-bin binlog_format=mixed binlog_cache_size=32m max_binlog_cache_size=64m max_binlog_size=512m long_query_time=1 log_output=FILE log-error=/data/mysql/3307/log/mysql-error.log slow_query_log=1 slow_query_log_file=/data/mysql/3307/log/slow_statement.log #log_queries_not_using_indexes general_log=0 general_log_file=/data/mysql/3307/log/general_statement.log #expire-logs-days = 14 binlog_expire_logs_seconds=1728000 relay-log=/data/mysql/3307/log/relay-bin relay-log-index=/data/mysql/3307/log/relay-bin.index #****** MySQL Replication New Feature********* master-info-repository=TABLE relay-log-info-repository=TABLE #relay-log-recovery #*********** INNODB Specific options *********** innodb_buffer_pool_size=2048M transaction-isolation=REPEATABLE-READ innodb_buffer_pool_instances=8 innodb_file_per_table=1 innodb_data_home_dir=/data/mysql/3307/innodb innodb_data_file_path=ibdata1:2048M:autoextend innodb_thread_concurrency=8 innodb_log_buffer_size=16M innodb_log_file_size=128M innodb_log_files_in_group=3 innodb_log_group_home_dir=/data/mysql/3307/innodb_log innodb_flush_log_at_trx_commit=2 innodb_max_dirty_pages_pct=70 innodb_flush_method=O_DIRECT [mysql] no-auto-rehash default-character-set=gbk prompt = (\u@\h) [\d]>_ 6、初始化数据库

（1） 3306

mysqld --defaults-file=/data/mysql/3306/my3306.cnf --initialize --user=mysql （2） 3307

mysqld --defaults-file=/data/mysql/3307/my3307.cnf --initialize --user=mysql 错误如下：

[mysql@mysql80 ~]$ mysqld --defaults-file=/data/mysql/3306/my.cnf --initialize --user=mysql

mysqld: /lib64/libstdc++.so.6: version `CXXABI_1.3.9' not found (required by mysqld)

mysqld: /lib64/libstdc++.so.6: version `GLIBCXX_3.4.21' not found (required by mysqld)

mysqld: /lib64/libstdc++.so.6: version `CXXABI_1.3.8' not found (required by mysqld)

mysqld: /lib64/libstdc++.so.6: version `GLIBCXX_3.4.20' not found (required by mysqld)

解析办法：

原因： 由于我们之前升级了gcc，也就是gcc-5.3.0. 但目录 /lib64/ 下的库文件链接的是 libstdc++.so.6 依然软链接是低版本 libstdc++.so.6.0.19

[root@mysql80 /]# cd /lib64/

[root@mysql80 lib64]# ls -l | grep libstdc++.so.6

lrwxrwxrwx. 1 root root 19 Jun 19 14:36 libstdc++.so.6 -> libstdc++.so.6.0.19

-rwxr-xr-x. 1 root root 991616 Apr 24 22:24 libstdc++.so.6.0.19

进入到新安装的gcc-5.3.0的目录，进入lib64，查看 libstdc++.so.6，软链接的是 libstdc++.so.6.0.21

[root@mysql80 gcc-5.3.0]# cd lib64/

[root@mysql80 lib64]# ls -l | grep libstdc++.so.6

lrwxrwxrwx. 1 root root 19 Jun 25 15:54 libstdc++.so -> libstdc++.so.6.0.21

lrwxrwxrwx. 1 root root 19 Jun 25 15:54 libstdc++.so.6 -> libstdc++.so.6.0.21

-rwxr-xr-x. 1 root root 11089328 Jun 25 15:54 libstdc++.so.6.0.21

处理： 删除原来的软链接，建立新的软链接：

[root@mysql80 lib64]# rm -rf libstdc++.so.6

[root@mysql80 lib64]# ln -s /usr/local/gcc-5.3.0/lib64/libstdc++.so.6 libstdc++.so.6

[root@mysql80 lib64]# ls -l | grep libstdc++.so.6

lrwxrwxrwx. 1 root root 41 Jun 26 14:48 libstdc++.so.6 -> /usr/local/gcc-5.3.0/lib64/libstdc++.so.6

7.启动服务

（1） 3306

/mysqld_safe --defaults-file=/data/mysql/3306/my.cnf --user=mysql &

（2）3307

/mysqld_safe --defaults-file=/data/mysql/3307/my.cnf --user=mysql &

8.登录数据库

这里以3306实例为例，3307步骤相同，只需要注意端口号即可，即大写的 -P

（1）查找root@localhost的初始密码，

查看当前错误日志

more /data/mysql/3306/log/mysql-error.log

找到如下行，标红的即是密码：

[MY-010454] [Server] A temporary password is generated for root@localhost: ?/ihz.ew8SIy

mysql -uroot -p'?/ihz.ew8SIy' -P3306 -S /data/mysql/3306/mysql.sock

（2）登录

mysql -uroot -p' ?/ihz.ew8SIy ' -P3306 -S /data/mysql/3306/mysql.sock

（3）修改密码

ALTER USER 'root'@'localhost' IDENTIFIED WITH sha256_password BY 'Yxc@3306' PASSWORD EXPIRE INTERVAL 360 DAY;

（4） 查询数据库

ysql> show databases;

+--------------------+

| Database |

+--------------------+

| information_schema |

| mysql |

| performance_schema |

| sys |

+--------------------+

4 rows in set (0.00 sec)

9. 校验后台进程
