CentOS6.9编译安装MySQL5.7.16

CentOS6.9编译安装MySQL5.7.16

部署环境：

系统CentOS6.9，mysql5.7.16，boost库

系统为2G内存

1、安装依赖包,使用yum安装cmake，6.9默认yum源自带

yum -y install gcc-c++ cmake bison-devel ncurses-devel

2、创建mysql的用户：

useradd -U -s /sbin/nologin mysql

3、创建必要的文件夹，并修改其目录用户所有者：

mkdir -pv /usr/local/mysql/etc

mkdir -pv /data/{boost/boost_1_59_0,mysql/{data,log}}

chown -R mysql:mysql /usr/local/mysql/

chown -R mysql:mysql /data/mysql/

4、将boots库拷贝到boost目录下

cp /tmp/boost/boost_1_59_0/* /data/boost/boost_1_59_0

chown -R mysql:mysql /data/boost/

5、编译安装mysql5.7

cd /tmp

tar xf mysql-5.7.16.tar.gz

cd mysql-5.7.16

cmake \

-DCMAKE_INSTALL_PREFIX=/usr/local/mysql \

-DMYSQL_DATADIR=/data/mysql/data \

-DSYSCONFDIR=/usr/local/mysql/etc \

-DWITH_MYISAM_STORAGE_ENGINE=1 \

-DWITH_INNOBASE_STORAGE_ENGINE=1 \

-DWITH_MEMORY_STORAGE_ENGINE=1 \

-DWITH_READLINE=1 \

-DMYSQL_UNIX_ADDR=/data/mysql/log/mysql.sock \

-DMYSQL_TCP_PORT=3306 \

-DENABLED_LOCAL_INFILE=1 \

-DWITH_PARTITION_STORAGE_ENGINE=1 \

-DEXTRA_CHARSETS=all \

-DDEFAULT_CHARSET=utf8 \

-DDEFAULT_COLLATION=utf8_general_ci \

-DWITH_BOOST=/data/boost/boost_1_59_0

make && make install

时间比较长

chown -R mysql:mysql /usr/local/mysql

6、配置文件my.cnf

[client]

port = 3306

socket = /data/mysql/log/mysql.sock

[mysql]

default-character-set = utf8

[mysqld]

# file

datadir =/data/mysql/data

basedir = /usr/local/mysql

pid-file =/data/mysql/log/mysqld.pid

log_error = /data/mysql/log/mysql.err

port = 3306

socket=/data/mysql/mysql.sock

user=mysql

character_set_server = utf8

character_set_server = utf8

slow_query_log = 1

slow_query_log_file = /data/mysql/log/slowq.log

long_query_time = 1

log-bin=/data/mysql/log/mysql-bin.log

# temp

max_tmp_tables = 64

tmp_table_size = 512M

table_open_cache = 216

thread_cache_size = 128

query_cache_type = 0

query_cache_size = 0

key_buffer_size = 128M

# innodb

innodb_flush_log_at_trx_commit = 2

innodb_flush_method = O_DIRECT

innodb_lock_wait_timeout = 50

#innodb_thread_concurrency = 24 16

innodb_buffer_pool_size = 1G

7、初始化数据库

版本在5.7.6前用的是mysql_install_db

版本5.7.6之后使用的mysqld --initialize

#####################官网标注#####################################

shell> bin/mysql_install_db --user=mysql # MySQL 5.7.5

shell> bin/mysqld --initialize --user=mysql # MySQL 5.7.6 and up

shell> bin/mysql_ssl_rsa_setup # MySQL 5.7.6 and up

#####################官网标注#####################################

/usr/local/mysql/bin/mysqld --initialize --user=mysql --datadir=/data/mysql/data --basedir=/usr/local/mysql

可能会出现内存不够的报错，自己优化下调节一下buffer大小就行了

/usr/local/mysql/bin/mysql_ssl_rsa_setup

没有打印日志，临时密码不能用，只好破解了，后面有方法。

8、启动数据库

vim /usr/local/mysql/support-files/mysql.server

加上绝对路径

basedir=/usr/local/mysql

datadir=/data/mysql/data

cp /usr/local/mysql/support-files/mysql.server /etc/init.d/mysqld

service mysqld start

9、配置环境变量

vim /etc/profile

export PATH=/usr/local/mysql/bin:$PATH

source /etc/profile

10、查看mysql临时密码，这项我这不用了，不好使，直接破解了。

cat /root/.mysql_secret

mysql -uroot -p`cat /root/.mysql_secret`

如果能进去，基本上到这就截止了，可以正常使用了。

**不能正常登录，使用临时密码无法登进去**

11、破解密码

mysqld_safe --defaults-file=/usr/local/mysql/etc/my.cnf --skip-grant-tables --skip-networking&

update mysql.user set authentication_string=password('123456') where user='root';

11.1、查找进程号，杀掉mysql进程

ps aux | grep mysql

kill -9 pid

service mysqld start

11.2、登录mysql

mysql -u root -p 'password'

提示修改密码：

mysql> alter user root@localhost identified by '123456';

ok了
