CentOS6.9+Mysql5.7.18源码安装

CentOS6.9+Mysql5.7.18源码安装，以下操作均在root用户下执行。

1、安装依赖工具

cmake make3.75+ gcc4.4.6+ Boost1.59.0 bison ncurses

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

cd /opt

wget https://sourceforge.net/projects/boost/files/boost/1.59.0/boost_1_59_0.tar.gz
或者向度娘要一个

tar -zxvf boost_1_59_0.tar.gz -C /usr/local/

2、下载mysql准备安装

git clone https://github.com/mysql/mysql-server.git

没有git就 yum install git装一个
选择5.7

创建mysql用户，用户组为root

useradd -r -g root -s /bin/false mysql

3、执行cmake

cd /opt/mysql-server5.7

cmake . -DCMAKE_INSTALL_PREFIX=/usr/local/mysql \
-DMYSQL_DATADIR=/usr/local/mysql/data \
-DWITH_BOOST=/usr/local/boost_1_59_0 \
-DMYSQL_UNIX_ADDR=/tmp/mysql.sock \
-DSYSCONFDIR=/etc \
-DEFAULT_CHARSET=utf8 \
-DDEFAULT_COLLATION=utf8_general_ci \
-DENABLED_LOCAL_INFILE=1 \
-DEXTRA_CHARSETS=all

-DCMAKE_INSTALL_PREFIX：安装路径-DMYSQL_DATADIR：数据存放目录-DWITH_BOOST：boost源码路径-DSYSCONFDIR：my.cnf配置文件目录-DEFAULT_CHARSET：数据库默认字符编码-DDEFAULT_COLLATION：默认排序规则-DENABLED_LOCAL_INFILE：允许从本文件导入数据-DEXTRA_CHARSETS：安装所有字符集 4、编译安装

make -j `grep processor /proc/cpuinfo | wc -l`

make install
-j参数表示根据CPU核数指定编译时的线程数，可以加快编译速度。
如果中途编译失败了，需要删除cmake生成的预编译配置参数的缓存文件和make编译后生成的文件，再重新编译。

cd /opt/mysql-server5.7
rm -f CMakeCache.txt
make clean

5、初始化系统数据库

vim /etc/my.cnf
进入insert模式，将原来内容替换成如下内容：

[client]
port=3306
socket=/temp/mysql.sock
[mysqld]
character-set-server=utf8
collation-server=utf8_general_ci

skip-external-locking
skip-name-resolve

user=mysql
port=3306
basedir=/usr/local/mysql
datadir=/usr/local/mysql/data
tmpdir=/usr/local/mysql/temp
# server_id = .....
socket=/usr/local/mysql/mysql.sock
log-error=/usr/local/mysql/logs/mysql_error.log
pid-file=/usr/local/mysql/mysql.pid
open_files_limit=10240
back_log=600
max_connections=500
max_connect_errors=6000
wait_timeout=605800
#open_tables=600
#table_cache = 650
#opened_tables = 630

max_allowed_packet=32M
sort_buffer_size=4M
join_buffer_size=4M
thread_cache_size=300
query_cache_type=1
query_cache_size=256M
query_cache_limit=2M
query_cache_min_res_unit=16k

tmp_table_size=256M
max_heap_table_size=256M

key_buffer_size=256M
read_buffer_size=1M
read_rnd_buffer_size=16M
bulk_insert_buffer_size=64M

lower_case_table_names=1

default-storage-engine=INNODB

innodb_buffer_pool_size=2G
innodb_log_buffer_size=32M
innodb_log_file_size=128M
innodb_flush_method=O_DIRECT
#####################
thread_concurrency=32
long_query_time=2
slow-query-log=on
slow-query-log-file=/usr/local/mysql/logs/mysql-slow.log

[mysqldump]
quick
max_allowed_packet=32M

[mysqld_safe]
log-error=/var/log/mysqld.log
pid-file=/var/run/mysqld/mysqld.pid

cd /usr/local/mysql

mkdir data

mkdir logs

mkdir temp

chmod 0770 -R .

./mysqld --initialize --user=mysql --datadir=/usr/local/mysql/data --basedir=/usr/local/mysql --socket=/tmp/mysql.sock

在MySQL 5.7.6版本以前是 bin/mysql_install_db --user

执行完成后，查看 logs/mysql_error.log文件，将里面的临时root密码记下来

A temporary password is generated for root@localhost: xxxxxxxxxx

6、配置mysql

chkconfig --add mysqld     # 添加到系统服务

chkconfig mysqld on        # 开机启动

service mysqld start启动不成功，使用safe模式启动

chown -R mysql:root /var/run/mysqld
./bin/mysqld_safe --defaults-file=/etc/my.cnf --user=mysql &

./mysql -uroot -p

输入mysql_error.log中的临时密码登入mysql控制台

set password='asdfghjkl'’；

Query OK, 0 rows affected (0.00 sec)

show warnings;

停止mysql

mysqladmin -u root -p shutdown

输入刚才设置的密码，停止成功

接下来可以使用系统服务来启动mysql了：

service mysqld start # 启动mysql服务
