自動化運維(1)之二進制部署MySQL5.7

二進制部署MySQL5.7

這個文檔用於基礎解釋，後面經過ansible的自動化對MySQL單實例進行安裝部署。

一、解壓文件

# tar zxvf mysql-5.7.22-linux-glibc2.12-x86_64.tar.gz -C /usr/local

二、重命名文件名稱

# cd /usr/local
# mv mysql-5.7.22-linux-glibc2.12-x86_64/ mysql/

三、新建mysql用戶

# groupadd mysql
# useradd -g mysql mysql

四、設置用戶操做系統資源的限制

# vi /etc/security/limits.conf
mysql soft nproc 65536
mysql hard nproc 65536
mysql soft nofile 65536
mysql hard nofile 65536

• 驗證limit是否生效

su - mysql
ulimit -a

五、建立MySQL數據目錄及賦予相應權限

#cd /data/
#mkdir -p /data/mysqldata/{3306/{data,tmp,binlog,innodb_ts,innodb_log},backup,scripts}
#chown -R mysql:mysql mysqldata

六、配置my.cnf

#su - mysql
[client]
port = 3306
socket = /data/mysqldata/3306/mysql.sock
# The MySQL server
[mysqld]
port = 3306
user = mysql
socket = /data/mysqldata/3306/mysql.sock
pid-file = /data/mysqldata/3306/mysql.pid
basedir = /usr/local/mysql
datadir = /data/mysqldata/3306/data
tmpdir = /data/mysqldata/3306/tmp
open_files_limit = 60000
explicit_defaults_for_timestamp
server-id = 1203306
lower_case_table_names = 1
character-set-server = utf8
federated
#sql_mode=STRICT_TRANS_TABLES
max_connections = 1000
max_connect_errors = 100000
interactive_timeout = 86400
wait_timeout = 86400
sync_binlog=0
back_log=100
default-storage-engine = InnoDB
log_slave_updates = 1

#*********** buffer **********************
net_buffer_length = 8K

query_cache_size = 128M
query_cache_limit = 2M
query_cache_min_res_unit = 2k

thread_cache_size = 300
table_open_cache = 1024
tmp_table_size = 256M

#*********** Logs related settings ***********

innodb_max_dirty_pages_pct = 70
innodb_flush_method=O_DIRECT
[mysql]

七、初始化數據庫mysql

$/usr/local/mysql/bin/mysqld --defaults-file=/data/mysqldata/3306/my.cnf --initialize-insecure --user=mysql

備註: --initialize生成一個隨機密碼
--initialize-insecure不生成隨機密碼

八、啓動mysql服務

$/usr/local/mysql/bin/mysqld_safe --defaults-file=/data/mysqldata/3306/my.cnf --user=mysql &

九、配置mysql環境變量

[mysql@MHA-Manager ~]$ vi .bash_profile
...相關配置文件...
PATH=$PATH:/usr/local/mysql/bin
...相關配置文件...
[mysql@MHA-Manager ~]$ source .bash_profile
[mysql@MHA-Manager ~]$ echo $PATH
[mysql@MHA-Manager ~]$ mysql
