MySQL server的搭建
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用戶和目錄創建，初始化等操作。未免日後遺忘，特保存在這裏。有些步驟可能會有錯，需要甄別。
註：mysql-5.7.9
1、關閉防火墻和SELINUX
2、建立mysql用戶組和用戶
groupadd mysql
useradd -g mysql -s /sbin/nologin mysql
3、 配置系統內核參數，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 編輯系統資源限制配置文件 vim /etc/security/limits.conf，在該文件下添加
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 文件，添加如下行
ulimit -u 16384 -n 65536
5、執行cmake命令，生成編譯配置文件
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用戶
chown -R mysql.mysql /usr/local/mysql
7、創建mysql數據目錄
mkdir -p /data/mysql
chown -R mysql.mysql /data/mysql
8、設置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 默認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、創建my.cnf文件，添加如下內容 vi /etc/my.cnf
[client]
port = 3306
socket = /tmp/mysql.sock
default-character-set = utf8mb4
[mysqld]
port = 3306

max_allowed_packet = 16M
[myisamchk]
key_buffer_size = 8M

write_buffer = 4M
EOF
10、初始化數據庫
/usr/local/mysql/bin/mysqld --initialize-insecure --user=mysql --basedir=/usr/local/mysql --datadir=/data/mysql
11、啟動mysql數據庫
service mysqld start
