2019-06-19 編譯安裝MySQL5.7.20步驟

環境：已安裝好系統版本CentOS7.4，虛擬機內存4G+8核i7 CPU
1.安裝準備
源碼包下載以及解壓：

cd /tmp
wget https://downloads.mysql.com/archives/get/file/mysql-boost-5.7.20.tar.gz
tar xf mysql-boost-5.7.20.tar.gz
cd mysql-boost-5.7.20/ && mkdir debug && cd debug

安裝mysql編譯相關插件&&建立data目錄

yum install bison cmake libaio-devel ncurses-devel -y
mkdir /data/mysql -p

2.編譯安裝mysql

cmake .. -DBUILD_CONFIG=mysql_release \
-DINSTALL_LAYOUT=STANDALONE \ 
-DCMAKE_BUILD_TYPE=RelWithDebInfo \ 
-DENABLE_DTRACE=OFF \
-DWITH_EMBEDDED_SERVER=1 \
-DWITH_INNODB_MEMCACHED=ON \ 
-DWITH_SSL=bundled \
-DWITH_ZLIB=system \ 
-DWITH_PAM=ON \ 
-DCMAKE_INSTALL_PREFIX=/usr/local/mysql \ 
-DINSTALL_PLUGINDIR="/usr/local/mysql/lib/plugin" \
-DDEFAULT_CHARSET=utf8 \
-DDEFAULT_COLLATION=utf8_general_ci \
-DWITH_EDITLINE=bundled -DFEATURE_SET=community \ 
-DWITH_DEBUG=off -DWITH_BOOST=../boost/boost_1_59_0 \ 
-DSYSCONFDIR=/etc -DMYSQL_DATADIR=/data/mysql \ 
-DMYSQL_UNIX_ADDR=/tmp/mysql.sock \
-DENABLED_LOCAL_INFILE=ON

看到 -- Configuring done -- Generating done表明編譯完成且沒有錯誤
注意：忽略警告，出現警告沒有影響。
下面正式開始make編譯（這裏能夠打開30個線程提升速度）以及安裝mysql文件

make -j12 && make install
[100%] Built target mysql_client_test_embedded
-- Installing: /usr/local/mysql/support-files/mysql.server

看到以上信息證實編譯和安裝完成而且沒有錯誤出現。
3.建立配置文件

cat >>/etc/mysql.cnf<<-EOF
[mysqld]
user=mysql
basedir=/usr/local/mysql
datadir=/data/mysql
server_id=1
port=3306
socket=/tmp/mysql.sock
[mysql]
socket=/tmp/mysql.sock
prompt=mysql [\\d]>
EOF

4.建立數據庫

groupadd mysql;useradd  -M -g mysql mysql -s /sbin/nologin
chown -R mysql.mysql  /usr/local/mysql  /data/mysql
echo "export PATH=$PATH:/usr/local/mysql/bin" >>/etc/profile
source /etc/profile
mysqld --initialize-insecure --user=mysql --basedir=/usr/local/mysql  --datadir=/data/mysql

5.啓動mysqld服務

cp /usr/local/mysql/support-files/mysql.server /etc/init.d/mysqld
/etc/init.d/mysqld start
ss -tnl|grep 3306
LISTEN     0      80          :::3306                    :::*

有以上信息出現證實本次安裝完成
備註：設置systemctl方式啓動，須要本身編制target文件並修改設置

cat >>/etc/systemd/system/mysqld.service<<-EOF
[Unit]

Documentation=man:mysqld(8)

[Install]
WantedBy=multi-user.target
[Service]
User=mysql
Group=mysql
ExecStart=/usr/local/mysql/bin/mysqld --defaults-file=/etc/my.cnf
LimitNOFILE=5000
EOF
