CentOS7.2安装MySQL5.7

今天测试在sentos7.2上安装MySQL5.7数据库,注意一centos的版本,和搭建流程。

一、查看确认centos的版本

[[email protected] ~]# cat /etc/redhat-release
CentOS Linux release 7.2.1511 (Core) 

二、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++-33

三、清除系统中mysql痕迹:

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

四、创建mysql用户和用户组:

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

五、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

六、解压、配置、编译、安装mysql_5.7:

tar zxvf mysql-5.7.11.tar.gz -C /usr/src
cd /usr/src/mysql-5.7.11
cmake \
-DCMAKE_INSTALL_PREFIX=/usr/local/mysql \
-DMYSQL_DATADIR=/home/mysql/data \
-DMYSQL_UNIX_ADDR=/home/mysql/pid/mysql.sock \
-DMYSQL_TCP_PORT=3306 \
-DMYSQL_USER=mysql \
-DEXTRA_CHARSETS=all \
-DDEFAULT_CHARSET=utf8 \
-DDEFAULT_COLLATION=utf8_general_ci \
-DWITH_READLINE=1 \
-DWITH_MYISAM_STORAGE_ENGINE=1 \
-DWITH_INNOBASE_STORAGE_ENGINE=1 \
-DWITH_ARCHIVE_STORAGE_ENGINE=1 \
-DWITH_BLACKHOLE_STORAGE_ENGINE=1 \
-DWITH_MEMORY_STORAGE_ENGINE=1 \
-DWITH_SSL=system \
-DWITH_ZLIB=system \
-DWITH_EMBEDDED_SERVER=1 \
-DENABLED_LOCAL_INFILE=1 \
-DENABLE_DOWNLOADS=1 \
-DDOWNLOAD_BOOST=1 \
-DWITH_BOOST=/usr/local/include/boost
make && make install

七、编辑my.cnf配置文件:

cp /usr/src/mysql-5.7.11/support-files/my-default.cnf /etc/my.cnf
vim /etc/my.cnf
[client]
port = 3306
socket = /home/mysql/pid/mysql.sock
default-character-set = utf8

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

[mysqld]
port = 3306
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 = 1
init-connect = 'SET NAMES utf8'
character-set-server = utf8
skip-name-resolve
skip-external-locking
back_log = 300
lower_case_table_names = 1
ft_min_word_len = 1
performance_schema = 0
explicit_defaults_for_timestamp=true

max_connections = 3896
max_connect_errors = 6000
open_files_limit = 65535
table_open_cache = 1024
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 = 64
query_cache_type = 1
query_cache_size = 256M
query_cache_limit = 2M

#log_bin = /home/mysql/log/mysql-bin
binlog_format = mixed
expire_logs_days = 7 
log_error = /home/mysql/log/mysql_error.log
slow_query_log = 1
long_query_time = 1
slow_query_log_file = /home/mysql/log/mysql-slow.log

default_storage_engine = InnoDB
#default-storage-engine = MyISAM
innodb_file_per_table = 1
innodb_open_files = 500
innodb_buffer_pool_size = 1024M
innodb_write_io_threads = 4
innodb_read_io_threads = 4
innodb_thread_concurrency = 0
innodb_purge_threads = 1
innodb_flush_log_at_trx_commit = 2
innodb_log_buffer_size = 2M
innodb_log_file_size = 32M
innodb_log_files_in_group = 3
innodb_max_dirty_pages_pct = 90
innodb_lock_wait_timeout = 120

bulk_insert_buffer_size = 8M
myisam_sort_buffer_size = 64M
myisam_max_sort_file_size = 10G
myisam_repair_threads = 1

interactive_timeout = 28800
wait_timeout = 28800

[mysqldump]
quick
max_allowed_packet = 20M

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

八、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

九、添加mysqld系统服务:

cp /usr/src/mysql-5.7.11/support-files/mysql.server /etc/init.d/mysqld
chmod +x /etc/init.d/mysqld
chkconfig --add mysqld
chkconfig --level 2345 mysqld on
chkconfig --list | grep mysqld

十、添加加载mysql库文件的路径:

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

十一、链接可执行文件到系统环境变量:

  1. ln -s /usr/local/mysql/lib/mysql /usr/lib64/mysql
  2. ln -s /usr/local/mysql/include/mysql /usr/include/mysql
  3. ln -s /usr/local/mysql/bin/mysql /usr/bin/mysql
  4. ln -s /usr/local/mysql/bin/mysqldump /usr/bin/mysqldump
  5. ln -s /usr/local/mysql/bin/myisamchk /usr/bin/myisamchk
  6. ln -s /usr/local/mysql/bin/mysqld_safe /usr/bin/mysqld_safe
  7. ln -s /usr/local/mysql/bin/mysqladmin /usr/bin/mysqladmin

十二、启动mysql服务:

  1. service mysqld start
  2. ps -aux | grep mysqld
  3. netstat -anptu | grep 3306

十三、 登录并修改mysql的root密码:

  1. 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 [email protected] = password('Passw0rd!');
grant all privileges on *.* to [email protected]'%' identified by 'Passw0rd!';
update mysql.user set Grant_priv='Y' where Host='%';
flush privileges;

# "Passwrd!" 是修改的密码

十四、防火墙开启3306端口:

iptables -A INPUT -p tcp --dport 3306 -j ACCEPT
