一：官网下载mysql二级制包。
1：官网下载一个MySQL二级制包，下载到/opt/mysql 目录下
Cd /opt/mysql
wget https://cdn.mysql.com//Downloads/MySQL-5.7/mysql-5.7.16-linux-glibc2.5-x86_64.tar.gz
二：mysql二级制包解压。
Cd /opt/mysql
tar -zxvf mysql-5.7.16-linux-glibc2.5-x86_64.tar.gz
三：设置mysql库文件路径与授权
1. 创建mysql软链接：
cd /usr/local
ln -s /opt/mysql/mysql-5.7.16-linux-glibc2.5-x86_64 mysql
2. 创建mysql运行的用户
groupadd mysql
useradd -g mysql -d /usr/local/mysql -s /sbin/nologin -M -n mysql
3. 创建mysql数据库库文件目录
mkdir -p /data/mysql/3306/{data,logs,tmp}
4.给目录授权mysql用户
chown -R mysql:mysql /data/mysql/3306/
chown -R mysql:mysql /usr/local/mysql/
四. 创建配置文件
vim /data/mysql/3306/my.cnf #my.cnf [client] port = 3306 socket = /tmp/mysql3306.sock [mysql] prompt="\u@\h:\p [\d]>" #pager="less -i -n -S" #tee=/data/mysql/3306/query.log no-auto-rehash [mysqld] #misc user = mysql basedir = /usr/local/mysql datadir = /data/mysql/3306/data port = 3306 socket = /tmp/mysql3306.sock event_scheduler = 0 tmpdir = /data/mysql/3306/tmp #timeout interactive_timeout = 3600 wait_timeout = 3600 #character set character-set-server = utf8 open_files_limit = 65535 max_connections = 500 max_connect_errors = 100000 lower_case_table_names =1 #symi replication #rpl_semi_sync_master_enabled=1 #rpl_semi_sync_master_timeout=1000 # 1 second #rpl_semi_sync_slave_enabled=1 #logs log-output=file slow_query_log = 1 slow_query_log_file = slow.log log-error = error.log log_warnings = 2 pid-file = mysql.pid long_query_time = 1 #log-slow-admin-statements = 1 #log-queries-not-using-indexes = 1 log-slow-slave-statements = 1 #binlog #binlog_format = STATEMENT binlog_format = row server-id = 13306 log-bin = /data/mysql/3306/logs/mysql-bin binlog_cache_size = 4M max_binlog_size = 256M max_binlog_cache_size = 1M sync_binlog = 0 expire_logs_days = 10 #procedure log_bin_trust_function_creators=1 # gtid-mode = on enforce-gtid-consistency=1 #relay log skip_slave_start = 1 max_relay_log_size = 128M relay_log_purge = 1 relay_log_recovery = 1 relay-log=relay-bin relay-log-index=relay-bin.index log_slave_updates #slave-skip-errors=1032,1053,1062 #skip-grant-tables #buffers & cache table_open_cache = 2048 table_definition_cache = 2048 table_open_cache = 2048 max_heap_table_size = 96M sort_buffer_size = 128K join_buffer_size = 128K thread_cache_size = 200 query_cache_size = 0 query_cache_type = 0 query_cache_limit = 256K query_cache_min_res_unit = 512 thread_stack = 192K tmp_table_size = 96M key_buffer_size = 8M read_buffer_size = 2M read_rnd_buffer_size = 16M bulk_insert_buffer_size = 32M #myisam myisam_sort_buffer_size = 128M myisam_max_sort_file_size = 1G myisam_repair_threads = 1 #innodb innodb_buffer_pool_size = 10G innodb_buffer_pool_instances = 1 innodb_data_file_path = ibdata1:1024M:autoextend innodb_flush_log_at_trx_commit = 2 innodb_log_buffer_size = 8M innodb_log_file_size = 100M innodb_log_files_in_group = 3 innodb_max_dirty_pages_pct = 50 innodb_file_per_table = 1 innodb_rollback_on_timeout innodb_status_file = 1 innodb_io_capacity = 200 transaction_isolation = READ-COMMITTED innodb_flush_method = O_DIRECT

五：数据库初始化
/usr/local/mysql
./bin/mysqld --defaults-file=/data/mysql/3306/my.cnf --basedir=/usr/local/mysql --datadir=/data/mysql/3306/data --user=mysql --initialize
[注意： ./bin/mysqld --initialize-insecure 密码为空]
查看初始化后随即生产的root@localhost密码
[root@yelj-centos7 ~]# cat /data/mysql/3306/data/error.log |grep "root@localhost"|awk -F " " '{print $11}'
D,wSi#<ad9Ij
六： 设置mysql变量
echo "export PATH=$PATH:/usr/local/mysql/bin">>/etc/profile
七： MySQL启动
/usr/local/mysql/bin/mysqld --defaults-file=/data/mysql/3306/my.cnf &
以下两种可以加入开机启动
chkconfig add mysql
echo “/usr/local/mysql/bin/mysqld_safe --defaults-file=/etc/my.cnf &” >>/etc/rc.local
八：快速创建实例
快速创建一个实例3307
3307
cd /data/mysql
cp –rp 3306 3307
cd 3307
sed -i 's/3306/3307/g' my3307.cnf
创建启动脚本
Echo “/usr/local/mysql/bin/mysqld --defaults-file=/data/mysql/3307/my.cnf &” > start.sh
九：关闭mysql服务
/usr/local/mysql/bin/mysqladmin –uroot –p –S /tmp/mysql3306.sock shutdown
