MySQL server的搭建

標籤：mysql   server   搭建   

無意間發現之前搭建MySQL的時候，有將操作過程記錄下來，涉及主機系統配置修改，MySQL使用者和目錄建立，初始化等操作。未免日後遺忘，特儲存在這裡。有些步驟可能會有錯，需要甄別。

註：mysql-5.7.9

1、關閉防火牆和SELINUX

2、建立mysql使用者組和使用者

groupadd mysql

useradd -g mysql -s /sbin/nologin mysql

3、 配置系統核心參數，增加如下配置

# vim /etc/sysctl.conf  

fs.aio-max-nr = 1048576 

fs.file-max = 6553560

啟用剛剛所做的變更， 輸入命令： # /sbin/sysctl -p 

4、修改系統資源限制  編輯系統資源限制設定檔 vim /etc/security/limits.conf，在該檔案下添加

如下行： 

# vim /etc/security/limits.conf 

mysql soft nproc 2047 

mysql hard nproc 16384 

mysql soft nofile 1024 

mysql hard nofile 65536

編輯 vim /etc/profile 檔案，添加如下行             

ulimit -u 16384 -n 65536         

5、執行cmake命令，產生編譯設定檔

cmake . -DCMAKE_INSTALL_PREFIX=/usr/local/mysql \

-DMYSQL_DATADIR=/data/mysql \

-DDOWNLOAD_BOOST=1 \

-DWITH_BOOST=../boost_1_59_0 \

-DSYSCONFDIR=/etc \

-DWITH_INNOBASE_STORAGE_ENGINE=1 \

-DWITH_PARTITION_STORAGE_ENGINE=1 \

-DWITH_FEDERATED_STORAGE_ENGINE=1 \

-DWITH_BLACKHOLE_STORAGE_ENGINE=1 \

-DWITH_MYISAM_STORAGE_ENGINE=1 \

-DENABLED_LOCAL_INFILE=1 \

-DENABLE_DTRACE=0 \

-DDEFAULT_CHARSET=utf8mb4 \

-DDEFAULT_COLLATION=utf8mb4_general_ci \

-DWITH_EMBEDDED_SERVER=1

編譯安裝 make &&　make install

6、修改mysql所在目錄的所有者為mysql使用者

chown -R mysql.mysql /usr/local/mysql

7、建立mysql資料目錄

mkdir -p /data/mysql

chown -R mysql.mysql /data/mysql

8、設定mysql開機啟動

cp /usr/local/mysql/support-files/mysql.server /etc/init.d/mysqld

chmod +x /etc/init.d/mysqld

chkconfig mysqld on

vi /etc/profile 預設mysql命令路徑，增加如下內容

export PATH=/usr/local/mysql/bin:$PATH

執行source使路徑生效  source /etc/profile

9、建立my.cnf檔案，添加如下內容  vi /etc/my.cnf

[client]

port = 3306

socket = /tmp/mysql.sock

default-character-set = utf8mb4

 

[mysqld]

port = 3306

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 = 8M

myisam_max_sort_file_size = 10G

myisam_repair_threads = 1

 

interactive_timeout = 28800

wait_timeout = 28800

 

[mysqldump]

quick

max_allowed_packet = 16M

 

[myisamchk]

key_buffer_size = 8M

sort_buffer_size = 8M

read_buffer = 4M

write_buffer = 4M

EOF

10、初始化資料庫

/usr/local/mysql/bin/mysqld --initialize-insecure --user=mysql --basedir=/usr/local/mysql --datadir=/data/mysql

11、啟動mysql資料庫

service mysqld start
