pxc測試機搭建過程

環境：

[root@pxc23 ~]# uname -r
2.6.39-400.17.1.el6uek.x86_64

192.168.56.21

192.168.56.22

192.168.56.23

1、下載：

http://www.percona.com/redir/downloads/Percona-XtraDB-Cluster/LATEST/binary/tarball/Percona-XtraDB-Cluster-5.5.39-rel36.0-25.11.828.Linux.x86_64.tar.gz

2、解壓

tar -xzvf Percona-XtraDB-Cluster-5.5.39-rel36.0-25.11.828.Linux.x86_64.tar.gz -C /usr/local
ln -sf /usr/local/Percona-XtraDB-Cluster-5.5.39-rel36.0-25.11.828.Linux.x86_64 /usr/local/mysql

3、檢測依賴包

[root@oel64 tmp]#  ldd /usr/local/mysql/bin/mysqld
linux-vdso.so.1 =>  (0x00007fff2d1ff000)
libpthread.so.0 => /lib64/libpthread.so.0 (0x000000395f200000)
libaio.so.1 => /lib64/libaio.so.1 (0x000000395ea00000)
libz.so.1 => /lib64/libz.so.1 (0x000000395fa00000)
librt.so.1 => /lib64/librt.so.1 (0x000000395fe00000)
libcrypt.so.1 => /lib64/libcrypt.so.1 (0x0000003961e00000)
libdl.so.2 => /lib64/libdl.so.2 (0x00007f75a20be000)
libssl.so.6 => not found
libcrypto.so.6 => not found
libstdc++.so.6 => /usr/lib64/libstdc++.so.6 (0x0000003963600000)
libm.so.6 => /lib64/libm.so.6 (0x000000395f600000)
libc.so.6 => /lib64/libc.so.6 (0x000000395ee00000)
/lib64/ld-linux-x86-64.so.2 (0x000000395e600000)
libfreebl3.so => /lib64/libfreebl3.so (0x0000003961a00000)
libgcc_s.so.1 => /lib64/libgcc_s.so.1 (0x0000003962e00000)

安裝依賴包

[root@oel64 tmp]# locate libssl.so libcrypto.so.10
/usr/lib64/.libcrypto.so.10.hmac
/usr/lib64/.libssl.so.1.0.0.hmac
/usr/lib64/.libssl.so.10.hmac
/usr/lib64/libcrypto.so.10
/usr/lib64/libssl.so.1.0.0
/usr/lib64/libssl.so.10


已有更高的版本，直接建個軟鏈就可以了
ln -s /usr/lib64/libcrypto.so.10 /usr/lib64/libcrypto.so.6
ln -s /usr/lib64/libssl.so.10 /usr/lib64/libssl.so.6

4、用戶

groupadd -r -g 306 mysql           #-r表示是僞用戶，只是用來運行mysql程序，不能登錄系統  
useradd -g 306  -r  -u 306 mysql

5、path

[root@OELX64 mysql]# cat ~/.bash_profile 
... ...
PATH=/usr/local/mysql/bin:/usr/lib64/qt-3.3/bin:/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/root/bin
export PATH

6、my.cnf

下面參數，測試機用，正式環境請測試驗正後再用

cat /etc/my.cnf

wsrep_node_address=192.168.56.21 #cluster當前節點的 ip 
不同的機子，改上面這兩個參數

7、建庫

rm /data/mysql/user_3306/ -rf
mkdir /data/mysql/user_3306/data -p
mkdir /data/mysql/user_3306/logs -p
mkdir /data/mysql/user_3306/tmp -p
chown -R mysql:mysql /data/mysql/*


cd /data/mysql/user_3306/data/
openssl genrsa -out private_key.pem 1024
openssl rsa -in private_key.pem -pubout > public_key.pem
chmod 444 public_key.pem
chmod 444 private_key.pem
chown mysql:mysql public_key.pem
chown mysql:mysql private_key.pem


cd /usr/local/mysql
# 必須在mysql目錄下執行
scripts/mysql_install_db --user=mysql  --defaults-file=/etc/my.cnf


cp /usr/local/mysql/support-files/mysql.server /data/mysql/user_3306/ 
chown -R mysql:mysql /data/mysql/*
cd /data/mysql/user_3306/


啓動時要注意第一個節點：
./mysql.server bootstrap-pxc
其它節點
./mysql.server start

安裝完成，去測試同步吧
