zookeeper 伪集群安装和 zkui管理UI配置
#=======================【VM机器,二进制安装】
# 安装环境
# OS System = CentOS-7.4 X64
# JDK = jdk-12.0.2
# zookeeper = zookeeper-3.6.1-x64
# zkui = zkui-2.0 , 备注：main.java有修复一个bug关于config.cfg路径获取。

#========================install zookeeper======================================================================== # step 1 设置系统swap 分区大小，参考如下公式： # RAM / Swap Space # Between 1 GB and 2 GB / 1.5 times the size of the RAM # Between 2 GB and 16 GB / Equal to the size of the RAM # More than 16 GB / 16 GB # 执行如下命令 # 然后，检查和设置swap那一行是否有被注释，如果被注释就要开启 cat /etc/fstab # 查看swap 空间大小(总计)： free -m # 查看swap 空间(file(s)/partition(s))： swapon -s # 查看磁盘路径的空间 df -h /home # 关闭所有的swap空间 swapoff -a # 创建新的swap文件，bs=表示每个block分块大小是1024 byte，count表示多少个block分块，所以总大小是bs*count=4GB dd if=/dev/zero of=/home/system-swap bs=1024 count=4194304 # 输出如下 # 4194304+0 records in # 4194304+0 records out # 4294967296 bytes (4.3 GB) copied, 29.991 s, 143 MB/s # 设置这个分区的权限为600 chmod -R 600 /home/system-swap # 把这个新建分区，变成swap分区 /sbin/mkswap /home/system-swap # 输出如下 # Setting up swapspace version 1, size = 4194300 KiB # no label, UUID=941e36a8-d389-4400-ad7d-07387e1da776 # 把这个新建分区，设置状态为open。 # 备注：重启之后，该swap分区还是失效，只有执行下面配置后才会永久生效。 /sbin/swapon /home/system-swap # 设置重启后，swap分区仍然有效 # 编辑如下文件，修改swap行内容为新加分区/home/system-swap cat /etc/fstab ##### /dev/mapper/centos-swap swap swap defaults 0 0 # /home/system-swap swap swap defaults 0 0 # 关闭SELINUX，设置参数SELINUXTYPE=disabled vi /etc/selinux/config # 修改参数如下 # # SELINUXTYPE=targeted SELINUXTYPE=disabled # ============================================================================================================= # step 2: 安装系统依赖软件 # 修改yum为国内镜像 === 看具体情况，有时候国内镜像不一定完整，这个时候还是要切换回国外地址 # cp /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.backup-linux && \ # wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo && \ yum clean all && \ yum makecache # 清理掉无用的repo yum --enablerepo=base clean metadata # 安装依赖软件 yum install binutils -y && \ yum install compat-libstdc++-33 -y && \ yum install gcc -y && \ yum install gcc-c++ -y && \ yum install glibc -y && \ yum install glibc-devel -y && \ yum install libgcc -y && \ yum install libstdc++ -y && \ yum install libstdc++-devel -y && \ yum install libaio -y && \ yum install libaio-devel -y && \ yum install libXext -y && \ yum install libXtst -y && \ yum install libX11 -y && \ yum install libXau -y && \ yum install libxcb -y && \ yum install libXi -y && \ yum install make -y && \ yum install sysstat -y && \ yum install zlib-devel -y && \ yum install elfutils-libelf-devel -y # yum rpm -q --queryformat %-{name}-%{version}-%{release}-%{arch}"\n" \ compat-libstdc++-33 glibc-kernheaders glibc-headers libaio libgcc glibc-devel xorg-x11-deprecated-libs # 输出无法下载和安装的软件，清单如下： # package compat-libstdc++-33 is not installed # package glibc-kernheaders is not installed # package glibc-headers is not installed # libaio-0.3.109-13.el7-x86_64 # libgcc-4.8.5-16.el7-x86_64 # package glibc-devel is not installed # package xorg-x11-deprecated-libs is not installed # 遇到部分无法在aliyun下载的软件，则需要重新替换yum.repo # cp /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.backup-aliyun && \ # cp /etc/yum.repos.d/CentOS-Base.repo.backup-linux /etc/yum.repos.d/CentOS-Base.repo && \ yum clean all && \ yum makecache && \ yum install -y compat-libstdc++* && \ yum install -y glibc-kernheaders* && \ yum install -y glibc-headers* && \ yum install -y libaio-* && \ yum install -y libgcc-* && \ yum install -y glibc-devel* && \ yum install -y xorg-x11-deprecated-libs* && \ # 确保，已经包含了libaio-0.3.106，默认开启异步I/O。 # 检查在操作系统中，是否开启AIO 异步读写IO cat /proc/slabinfo | grep kio # 如果没有开启，则在下面文件中，增加如下两行 vi /proc/slabinfo kioctx 51 120 320 12 1 : tunables 54 27 8 : slabdata 10 10 0 kiocb 30 30 256 15 1 : tunables 120 60 8 : slabdata 2 2 0 # ============================================================================================================= # step 3: 创建zookeper安装目录 mkdir -p /opt/soft/{jdk,zookeeper} # 然后上传jdk或zookeeper 二进制文件到上面创建的软件目录 # 创建zookeeper的安装主目录 mkdir -p /app/zookeeper && \ # 创建zookeeper的数据主目录 mkdir -p /data/zookeeper && \ # 创建zookeeper的日志主目录 mkdir -p /log/zookeeper # ============================================================================================================= # step 4: zookeeper安装用户和组的创建 # 使用root用户，进行如下操作： # 创建ops_install组 groupadd -g 5000 ops_install # 创建ops_admin组 groupadd -g 501 ops_admin # 创建zookeeper用户 useradd -g ops_install -G ops_admin zookeeper # 修改zookeeper密码 echo 'password'|passwd --stdin zookeeper # 删除用户和其以来的用户文件 # userdel -r zookeeper # 查看用户zookeeper权限是否设置正确，正确输出结果如下 # id zookeeper # [root@CNT7XZKPD02 ~]# id zookeeper # uid=1001(zookeeper) gid=5000(ops_install) groups=5000(ops_install),501(ops_admin) # ============================================================================================================= # step 5: 安装用户的profile文件的设置 # 编辑/etc/profile，加入以下内容 vi /etc/profile # -----------------------java env----------------------------------------------------------------- JAVA_HOME=/env/jdk/jdk-12.0.2 PATH=$JAVA_HOME/bin:$JAVA_HOME/jre/bin:$PATH CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar #

-----------------------zookeeper env--------------------------------------------------------------- # 生效配置环境变量 source /etc/profile # 检查生效环境变量 env | grep ZOOKEEPER env | grep JAVA # ============================================================================================================= # step 5: 安装jdk 8 # 创建jdk的软件目录和安装目录，分别如下： mkdir -p /opt/soft/jdk/ && \ mkdir -p /env/jdk/ # 然后，通过WinSCP工具，把JDK 8二进制安装包tar复制到软件目录 ls -al /opt/soft/jdk/jdk-12.0.2_linux-x64_bin.tar.gz # 解压jdk到安装目录 tar -zxvf /opt/soft/jdk/jdk-12.0.2_linux-x64_bin.tar.gz -C /env/jdk/ #
