WCS安装完毕之后把日志设置在其他数据盘

更新:新买的4T硬盘创建分区只有2T，后来使用gparted分区

==============================================================

WCS系统当设备很多时产生的日志非常多，几天就没了，默认是/分配了50G，但是现场比较多的情况系统运行一段时间后磁盘空间满，导致数据库查询失败，登录失败。

从最开始说起，一般客户私有云部署好之后，软件安装的分区比较小，但同时有分配比较大的数据盘，需要自行设置。

1.查看当前分区情况

[root@jx-t---02 ~]# df -h
Filesystem               Size  Used Avail Use% Mounted on
devtmpfs                 7.8G     0  7.8G   0% /dev
tmpfs                    7.8G     0  7.8G   0% /dev/shm
tmpfs                    7.8G   65M  7.7G   1% /run
tmpfs                    7.8G     0  7.8G   0% /sys/fs/cgroup
/dev/mapper/centos-root   27G  2.4G   25G   9% /
/dev/sda1               1014M  190M  825M  19% /boot

　　根目录/只有25G，太少了

2.查看磁盘大小

[root@jx-t---02 ~]# fdisk -l

Disk /dev/sda: 107.4 GB, 107374182400 bytes, 209715200 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk label type: dos
Disk identifier: 0x000b4705

   Device Boot      Start         End      Blocks   Id  System
/dev/sda1   *        2048     2099199     1048576   83  Linux
/dev/sda2         2099200    62914559    30407680   8e  Linux LVM

Disk /dev/mapper/centos-root: 29.0 GB, 28982640640 bytes, 56606720 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes


Disk /dev/mapper/centos-swap: 2147 MB, 2147483648 bytes, 4194304 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes


Disk /dev/sdb: 107.4 GB, 107374182400 bytes, 209715200 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes

　　我们看到/dev/sda和/dev/sdb都有107.4GB，这次我把sdb当作数据盘，存储日志和数据.

3 给磁盘分区

[root@jx-t---02 ~]# fdisk /dev/sdb
Welcome to fdisk (util-linux 2.23.2).

Changes will remain in memory only, until you decide to write them.
Be careful before using the write command.

Device does not contain a recognized partition table
Building a new DOS disklabel with disk identifier 0xccc31773.

Command (m for help):

　　m可以查看帮助

Command (m for help): m
Command action
   a   toggle a bootable flag
   b   edit bsd disklabel
   c   toggle the dos compatibility flag
   d   delete a partition
   g   create a new empty GPT partition table
   G   create an IRIX (SGI) partition table
   l   list known partition types
   m   print this menu
   n   add a new partition
   o   create a new empty DOS partition table
   p   print the partition table
   q   quit without saving changes
   s   create a new empty Sun disklabel
   t   change a partition's system id
   u   change display/entry units
   v   verify the partition table
   w   write table to disk and exit
   x   extra functionality (experts only)

　　我们输入p查看磁盘分区情况

Command (m for help): p

Disk /dev/sdb: 107.4 GB, 107374182400 bytes, 209715200 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk label type: dos
Disk identifier: 0xccc31773

   Device Boot      Start         End      Blocks   Id  System

　　没有分区，是个新的盘。我们输入n来创建一个新的分区

Command (m for help): n
Partition type:
   p   primary (0 primary, 0 extended, 4 free)
   e   extended

　　让我们选主分区还是扩展分区，这里输入p，创建主分区

后面分别是会让输入分区号、开始扇区、结束扇区，我这里只有一个分区，所以都直接回车，默认值

Partition number (1-4, default 1): 1
First sector (2048-209715199, default 2048): 
Using default value 2048
Last sector, +sectors or +size{K,M,G} (2048-209715199, default 209715199): 
Using default value 209715199
Partition 1 of type Linux and of size 100 GiB is set

　　再次输入p，查看分区信息

Command (m for help): p

Disk /dev/sdb: 107.4 GB, 107374182400 bytes, 209715200 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk label type: dos
Disk identifier: 0xccc31773

   Device Boot      Start         End      Blocks   Id  System
/dev/sdb1            2048   209715199   104856576   83  Linux

　　确认无误后按w，保存分区

Command (m for help): w
The partition table has been altered!

Calling ioctl() to re-read partition table.
Syncing disks.

　　分区完成之后，开始格式化分区

查看当前系统分区格式

[root@jx-t---02 ~]# mount |grep "^/dev"
/dev/mapper/centos-root on / type xfs (rw,relatime,attr2,inode64,noquota)
/dev/sda1 on /boot type xfs (rw,relatime,attr2,inode64,noquota)

[root@jx-t---02 ~]# df -hT
Filesystem              Type      Size  Used Avail Use% Mounted on
devtmpfs                devtmpfs  7.8G     0  7.8G   0% /dev
tmpfs                   tmpfs     7.8G     0  7.8G   0% /dev/shm
tmpfs                   tmpfs     7.8G   65M  7.7G   1% /run
tmpfs                   tmpfs     7.8G     0  7.8G   0% /sys/fs/cgroup
/dev/mapper/centos-root xfs        27G  2.4G   25G   9% /
/dev/sda1               xfs      1014M  190M  825M  19% /boot

　　当前系统使用xfs，我们新的分区也采用这个格式

格式化分区

[root@jx-t---02 ~]# mkfs.xfs /dev/sdb1
meta-data=/dev/sdb1              isize=512    agcount=4, agsize=6553536 blks
         =                       sectsz=512   attr=2, projid32bit=1
         =                       crc=1        finobt=0, sparse=0
data     =                       bsize=4096   blocks=26214144, imaxpct=25
         =                       sunit=0      swidth=0 blks
naming   =version 2              bsize=4096   ascii-ci=0 ftype=1
log      =internal log           bsize=4096   blocks=12799, version=2
         =                       sectsz=512   sunit=0 blks, lazy-count=1
realtime =none                   extsz=4096   blocks=0, rtextents=0

　　创建一个目录

[root@jx-t---02 ~]# mkdir /data

　　在这个目录下，挂载当前分区

[root@jx-t---02 ~]# mount -t xfs /dev/sdb1 /data

　　查看当前系统分区情况

[root@jx-t---02 ~]# df -HT
Filesystem              Type      Size  Used Avail Use% Mounted on
devtmpfs                devtmpfs  8.4G     0  8.4G   0% /dev
tmpfs                   tmpfs     8.4G     0  8.4G   0% /dev/shm
tmpfs                   tmpfs     8.4G   68M  8.3G   1% /run
tmpfs                   tmpfs     8.4G     0  8.4G   0% /sys/fs/cgroup
/dev/mapper/centos-root xfs        29G  2.6G   27G   9% /
/dev/sda1               xfs       1.1G  200M  865M  19% /boot
/dev/sdb1               xfs       108G   34M  108G   1% /data

　　sdb1已经挂载到/data

添加到开机自动挂载，/dev/fstab添加最后一行

　4. WCS的日志文件文件目录设置软连接

这次给WCS的3个服务的日志文件夹设置软连接

首先创建文件夹

mkdir /data/log
mkdir /data/log/WCS
mkdir /data/log/mts_node
mkdir /data/log/wcs_gateway

　　然后停止这3个服务

systemctl stop WCS
systemctl stop wcs_gateway
systemctl stop mts_node

　　删除/var/log下对应的3个日志目录

rm -rf /var/log/WCS /var/log/mts_node /var/log/wcs_gateway

　　创建3个软连接

ln -s /data/log/mts_node /var/log/mts_node
ln -s /data/log/wcs_gateway /var/log/wcs_gateway
ln -s /data/log/WCS /var/log/WCS

　　启动3个服务

systemctl start wcs_gateway
systemctl start mts_node
systemctl start WCS

　　设置完毕，这样可以不用修改每个服务的配置文件。

查看日志

[root@jx-t---02 ~]# tail -f /var/log/WCS/WCS.log 
      "free_cnt2" : 0,
      "media_cnt" : 0,
      "sender_cnt" : 0,
      "version" : "2.0"
   },
   "request" : "notify",
   "type" : "MTS statistic"
}
