CentOS_7.2安装MySQL_5.7

一、安装依赖包和开发工具：

yum install vim vim-enhanced wget zip unzip telnet ntsysv compat* apr* nasm* gcc gcc* gcc-c++ ntp make imake cmake automake autoconf python-devel zlib zlib-devel glibc glibc-devel glib2 libxml glib2-devel libxml2 libxml2-devel bzip2 bzip2-devel libXpm libXpm-devel libidn libidn-devel libtool libtool-ltdl-devel* libmcrypt libmcrypt-devel libevent-devel libmcrypt* libicu-devel libxslt-devel postgresql-devel curl curl-devel perl perl-Net-SSLeay pcre pcre-devel ncurses ncurses-devel openssl openssl-devel openldap openldap-devel openldap-clients openldap-servers krb5 krb5-devel e2fsprogs e2fsprogs-devel libjpeg libpng libjpeg-devel libjpeg-6b libjpeg-devel-6b libpng-devel libtiff-devel freetype freetype-devel fontconfig-devel gd gd-devel kernel screen sysstat flex bison nss_ldap pam-devel compat-libstdc++-

二、清除系统中mysql痕迹：

yum remove mysql
rm -f /etc/my.cnf

三、创建mysql用户和用户组：

groupadd mysql
useradd -s /sbin/nologin -M -g mysql mysql

四、安装boost：

tar zxvf boost_1_60_0.tar.gz -C /usr/src
cd /usr/src/boost_1_60_0
./bootstrap.sh
./b2 --prefix=/usr/local
./b2 install

五、解压、配置、编译、安装mysql_5.7：

tar zxvf mysql-.tar.gz -C /usr/src
cd /usr/src/mysql-
cmake \
-DCMAKE_INSTALL_PREFIX=/usr/local/mysql \
-DMYSQL_DATADIR=/home/mysql/data \
-DMYSQL_UNIX_ADDR=/home/mysql/pid/mysql.sock \
-DMYSQL_TCP_PORT= \
-DMYSQL_USER=mysql \
-DEXTRA_CHARSETS=all \
-DDEFAULT_CHARSET=utf8 \
-DDEFAULT_COLLATION=utf8_general_ci \
-DWITH_READLINE= \
-DWITH_MYISAM_STORAGE_ENGINE= \
-DWITH_INNOBASE_STORAGE_ENGINE= \
-DWITH_ARCHIVE_STORAGE_ENGINE= \
-DWITH_BLACKHOLE_STORAGE_ENGINE= \
-DWITH_MEMORY_STORAGE_ENGINE= \
-DWITH_SSL=system \
-DWITH_ZLIB=system \
-DWITH_EMBEDDED_SERVER= \
-DENABLED_LOCAL_INFILE= \
-DENABLE_DOWNLOADS= \
-DDOWNLOAD_BOOST= \
-DWITH_BOOST=/usr/local/include/boost
make && make install

六、编辑my.cnf配置文件：

cp /usr/src/mysql-/support-files/my-default.cnf /etc/my.cnf
vim /etc/my.cnf

[client]
port =
socket = /home/mysql/pid/mysql.sock
default-character-set = utf8

[mysql]
prompt="MySQL [\d]> "
no-auto-rehash
default-character-set = utf8

[mysqld]
port =
socket = /home/mysql/pid/mysql.sock
datadir = /home/mysql/data
pid-file = /home/mysql/pid/mysqld.pid
user = mysql
bind-address = 0.0.0.0
server-id =
init-connect = 'SET NAMES utf8'
character-set-server = utf8
skip-name-resolve
skip-external-locking
back_log =
lower_case_table_names =
ft_min_word_len =
performance_schema =
explicit_defaults_for_timestamp=true

max_connections =
max_connect_errors =
open_files_limit =
table_open_cache =
max_allowed_packet = 10M
binlog_cache_size = 1M
max_heap_table_size = 8M
tmp_table_size = 128M
read_buffer_size = 16M
read_rnd_buffer_size = 32M
sort_buffer_size = 16M
join_buffer_size = 8M
key_buffer_size = 256M
thread_cache_size =
query_cache_type =
query_cache_size = 256M
query_cache_limit = 2M

#log_bin = /home/mysql/log/mysql-bin
binlog_format = mixed
expire_logs_days =
log_error = /home/mysql/log/mysql_error.log
slow_query_log =
long_query_time =
slow_query_log_file = /home/mysql/log/mysql-slow.log

default_storage_engine = InnoDB
#default-storage-engine = MyISAM
innodb_file_per_table =
innodb_open_files =
innodb_buffer_pool_size = 1024M
innodb_write_io_threads =
innodb_read_io_threads =
innodb_thread_concurrency =
innodb_purge_threads =
innodb_flush_log_at_trx_commit =
innodb_log_buffer_size = 2M
innodb_log_file_size = 32M
innodb_log_files_in_group =
innodb_max_dirty_pages_pct =
innodb_lock_wait_timeout = 

bulk_insert_buffer_size = 8M
myisam_sort_buffer_size = 64M
myisam_max_sort_file_size = 10G
myisam_repair_threads = 

interactive_timeout =
wait_timeout = 

[mysqldump]
quick
max_allowed_packet = 20M

[myisamchk]
key_buffer_size = 256M
sort_buffer_size = 32M
read_buffer = 16M
write_buffer = 16M

七、修改目录权限、生成新的mysql授权表：

mkdir -p /home/mysql/log
mkdir -p /home/mysql/data
chown -R mysql:mysql /home/mysql/
/usr/local/mysql/bin/mysql_install_db --defaults-file=/etc/my.cnf --user=mysql --datadir=/home/mysql/data --basedir=/usr/local/mysql

八、添加mysqld系统服务：

cp /usr/src/mysql-/support-files/mysql.server /etc/init.d/mysqld
chmod +x /etc/init.d/mysqld
chkconfig --add mysqld
chkconfig --level  mysqld on
chkconfig --list | grep mysqld

九、添加加载mysql库文件的路径：

echo /usr/local/mysql/lib >> /etc/ld.so.conf.d/mysql-x86_64.conf
echo /usr/lib64/mysql >> /etc/ld.so.conf.d/mysql-x86_64.conf
cp /etc/ld.so.conf.d/mysql-x86_64.conf  /etc/ld.so.conf.d/mysql.conf
ldconfig

十、链接可执行文件到系统环境变量：

ln -s /usr/local/mysql/lib/mysql /usr/lib64/mysql
ln -s /usr/local/mysql/include/mysql /usr/include/mysql
ln -s /usr/local/mysql/bin/mysql /usr/bin/mysql
ln -s /usr/local/mysql/bin/mysqldump /usr/bin/mysqldump
ln -s /usr/local/mysql/bin/myisamchk /usr/bin/myisamchk
ln -s /usr/local/mysql/bin/mysqld_safe /usr/bin/mysqld_safe
ln -s /usr/local/mysql/bin/mysqladmin /usr/bin/mysqladmin

十一、启动mysql服务：

service mysqld start
ps -aux | grep mysqld
netstat -anptu | grep 

十二、登录并修改mysql的root密码：

cat ~/.mysql_secret

# 查看mysql默认的初始密码

mysql -uroot -p 

# 输入.mysql_secret文件内的初始密码

set password for root@localhost = password('Passw0rd!');
grant all privileges on *.* to root@'%' identified by 'Passw0rd!';
update mysql.user set Grant_priv='Y' where Host='%';
flush privileges;

# "Passwrd!" 是修改的密码

十三、防火墙开启3306端口：
iptables -A INPUT -p tcp --dport 3306 -j ACCEPT
