编译安装Mysql5.7

苟哥 2021-05-24 PM 1088℃ 0条

MySQL5.7版本有比较大的变化，在安装上也有不小区别，需要boost库，为了方便，我们直接安装自带boost的mysql（当然也可以先安装纯mysql，再单独安装boost库）。

#### 一、安装相关依赖
```shell
yum install -y  gcc gcc-c++ cmake ncurses ncurses-devel bison
```
#### 二、下载mysql-boost源码包
```shell
mkdir ~/src
cd src
wget https://dev.mysql.com//Downloads/MySQL-5.7/mysql-boost-5.7.25.tar.gz
```
#### 三、编译安装
1、添加mysql用户
```shell
useradd -s /sbin/nologin  mysql
```
2、创建mysql数据目录
```shell
mkdir -p /data/mysql/data
chown -R mysql:mysql /data/mysql
```
3、安装
```shell
mkdir /usr/local/mysql
tar -xzvf mysql-boost-5.7.25.tar.gz  /usr/local/mysql
cmake -DDEFAULT_CHARSET=utf8 -DDEFAULT_COLLATION=utf8_unicode_ci -DWITH_BOOST=boost
make && make install
```
4、配置
```shell
vim /etc/my.cnf
```
根据自身实际需求修改配置项
```
[client]
#password       = your_password
port            = 3306
socket          = /tmp/mysql.sock

[mysqld]
port            = 3306
socket          = /tmp/mysql.sock
datadir = /data/mysql/data
default_storage_engine = InnoDB
performance_schema_max_table_instances = 400
table_definition_cache = 400
skip-external-locking
key_buffer_size = 32M
max_allowed_packet = 100G
table_open_cache = 128
sort_buffer_size = 768K
net_buffer_length = 4K
read_buffer_size = 768K
read_rnd_buffer_size = 256K
myisam_sort_buffer_size = 8M
thread_cache_size = 16
query_cache_size = 16M
tmp_table_size = 32M
sql-mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES

explicit_defaults_for_timestamp = true
#skip-name-resolve
max_connections = 500
max_connect_errors = 100
open_files_limit = 65535

log-bin=mysql-bin
binlog_format=mixed
server-id = 1

expire_logs_days = 10
slow_query_log=1
slow-query-log-file=/data/mysql/mysql-slow.log
long_query_time=3
#log_queries_not_using_indexes=on
early-plugin-load = ""

innodb_data_home_dir = /data/mysql/data
innodb_data_file_path = ibdata1:10M:autoextend
innodb_log_group_home_dir = /data/mysql/data
innodb_buffer_pool_size = 128M
innodb_log_file_size = 64M
innodb_log_buffer_size = 16M
innodb_flush_log_at_trx_commit = 1
innodb_lock_wait_timeout = 50
innodb_max_dirty_pages_pct = 90
innodb_read_io_threads = 1
innodb_write_io_threads = 1

[mysqldump]
quick
max_allowed_packet = 500M

[mysql]
no-auto-rehash

[myisamchk]
key_buffer_size = 32M
sort_buffer_size = 768K
read_buffer = 2M
write_buffer = 2M

[mysqlhotcopy]
interactive-timeout

```
5、初始化
```shell
cd /usr/local/mysql/bin
./mysqld --initialize-insecure --user=mysql --basedir=/usr/local/mysql --datadir=/data/mysql/data
```
6、添加环境变量
```shell
#在 /etc/profile 新增一行
PATH=/usr/local/mysql/bin:$PATH
```
保存退出后让环境变量生效：
```shell
source /etc/profile
```
7、设置开机启动
```shell
ln -s /usr/local/mysql/bin/* /usr/local/bin/
cp /usr/local/mysql/support-files/mysql.server /etc/init.d/mysqld
chmod +x /etc/init.d/mysqld
systemctl enable mysqld
```
8、启动mysql并设置root密码
```shell
systemctl start mysqld
mysql -uroot  -p
#初始密码为空，所以直接回车
```
修改密码
```shell
set password='123456'
```
