MySQL安裝-單機多實例(9)

時間  2020-10-03 標籤 mysql 安裝 單機 實例

單機多實例1
簡單來講就是在一臺機器上開啓多個不一樣的服務端口（3306,3307）運行多個MySQL服務進程，共用一套安裝程序，這些服務進程經過不一樣的socket監聽不一樣的服務端口來提供各自的服務。
環境設置
1 關閉防火牆
systemctl stop firewalld.service && systemctl disable firewalld.service
2 關閉selinux
sed -i 's/SELINUX=enforcing/SELINUX=disabled/' /etc/selinux/config
grep SELINUX=disabled /etc/selinux/config
3 設置計算機名
hostnamectl set-hostname MySQLmu.test.com
4 刪除mariadb數據庫
rpm -qa mariadb
rpm -e --nodeps mariadb-libs-5.5.60-1.el7_5.x86_64
5 從新啓動系統
reboot
編譯安裝MySQL
1 安裝依賴
yum -y install gcc-c++ ncurses-devel cmake make perl gcc autoconf automake zlib libxml libgcrypt libtool bison lrzsz
2 下載源碼
https://dev.MySQL.com/downloads/MySQL/
Select Operating System: Source Code
Select OS Version:Generic Linux
3 下載帶boost庫的源碼
wget --no-check-certificate http://sourceforge.net/projects/boost/files/boost/1.59.0/boost_1_59_0.tar.gz
wget https://dev.MySQL.com/get/Downloads/MySQL-5.7/MySQL-5.7.26.tar
添加用戶和組
groupadd -r MySQL && useradd -r -g MySQL -s /sbin/nologin -M MySQL
解壓
tar -zxvf boost_1_59_0
tar -zxvf MySQL-5.7.26
1 添加文件夾並賦予權限
mkdir -p /usr/local/MySQL/tmp
chown -R MySQL:MySQL /usr/local/MySQL
2 建立文件夾能夠批量建立
mkdir -pv /data/MySQL/{3306,3307}/{pid,cnf,data,sockt,tmp,log,log-bin}
chown -R MySQL:MySQL /data/MySQL
find /data/ -type f -name "MySQL" |xargs chmod +x
find /data/ -type f -name "MySQL" |xargs ls -l
3 解壓文件包
tar -zxvf MySQL-5.7.26.tar.gz && tar -zxvf boost_1_59_0.tar.gz
cd MySQL-5.7.26/
cmake . -DCMAKE_INSTALL_PREFIX=/usr/local/MySQL \
-DMYSQL_DATADIR=/data/MySQL \
-DWITH_BOOST=../boost_1_59_0 \
-DSYSCONFDIR=/etc \
-DMYSQL_UNIX_ADDR=/usr/local/MySQL/tmp/MySQL.sock \
-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
4 編譯安裝
make -j$(cat /proc/cpuinfo| grep "processor"| wc -l) && make install
ls -lrt /usr/local/MySQL
cp /usr/local/MySQL/support-files/MySQL.server /etc/init.d/MySQLd
chmod +x /etc/init.d/MySQLd
echo -e '\n\nexport PATH=/usr/local/MySQL/bin:$PATH\n' >> /etc/profile && source /etc/profile
