The entire process of installing the YouCompleteMe plug-in CentOS,

After several twists and turns throughout the process, I searched a lot of online blogs. Refer to the following:

I have tried to install CentOS6.9 and CentOS7. The installation steps are as follows: (The write is rough)

1,

Win10 x64: connect to the network through a wireless network adapter:
IP: 192.168.1.106
Netmast: 255.255.255.0
Gateway: 192.168.1.1
DNS: 120.196.165.24
211.136.192.6
In vmware, the network uses the bridging mode. Select copy physical connection to the network. Remove all other wireless network adapters.

Centos6.9-x64
IP: 192.168.1.6/255.255.255.0/192.168.1.1 same network segment

For CentOS7-x86, pay attention to adding NICs, and pay attention to network settings, GATEWAY
1) disable the VM. VMare workstation. Add ethernet0.virtualDev = "e1000" to. vmx in the installation directory of the corresponding VM"
2) restart, ip addr-> cp/etc/sysconfig/network-scripts/ifg-lo/ect/sysconfig/network-scripts/ifg-ens33

Check whether network settings are correct

Ping 192.168.1.106
Ping 192.168.1.1
Ping www.baidu.com // pass

2. Add a hard disk to the VM to learn 20 gb scsi.
Reboot
Fdisk/dev/sdb
Mkfs. ext4/dev/sdb1
Echo "/dev/sdb1/learn ext4defaults 0 0">/etc/fstab

3. Add User kk4728
Useradd kk4728
Passwd kk4728
Add a sudo user,/etc/sudoers add kk4728 ALL = (ALL) ALL
Modify learning disk Permissions
Chown-R kk4728/learn
Chgrp-R kk4728/learn
Chmod-R 775/learn

4. Set Environment Variables
Vi ~ /. Add bash_profile
PATH = $ PATH :.
Allows the system to find the current Executable File

5. Synchronization time
Sudo yum install ntp
Sudo ntpdate time.nist.gov

6. Install Dependencies
Sudo yum install-y gcc-c ++ gdb ctags ncurses-devel libevent-devel git automake xz zlib-devel cmake libxml2 libxslt-devel kernel-devel wget openssl-devel

Gcc4.8.5 is installed by default in centos 7.
Glibc-2.17
Python-1, 2.7.5

7. Upgrade glibc
Wget http://ftp.gnu.org/pub/gnu/glibc/glibc-2.17.tar.xz
Xz-d glibc-2.17.tar.xz
Tar-xvf glibc-2.17.tar
Cd glibc-2.17
Mkdir build
Cd build
../Configure -- prefix =/usr -- disable-profile -- enable-add-ons -- with-headers =/usr/include -- with-binutils =/usr/bin
Sudo make & make install

An error occurred while installing libc. a write permission failed. Separate installation
Sudo make
Sudo make install

Verification:
X64: strings/lib64/libc. so.6 | grep GLIBC
X86: strings/lib/libc. so.6 | grep GLIBC

If verification fails. It should be the path that libc. so.6 (soft connection) points to is not correct. Here we will not upgrade, as needed later. The file pointed to by libc. so.6 is too critical;
Improper use may cause the system to fail to log on or restart. Some command segments are incorrect !!!
Find/-name "libc. so.6"
Cp/usr/glibc-2.17/lib/libc-2.17.so/lib/libc-2.17.so
Rm-rf/lib/libc. so.6
If an exception occurs later, the main reason is that libc. so.6 is the core link library of the system. An error occurred while deleting most commands!
You need to re-create the link, but ln also needs libc. so.6. You need to manually add the LD_PRELOAD path
[Root # localhost ~ ] LD_PRELOAD =/lib/libc-2.17.so ln-s/lib/libc-2.17.so/lib/libc. so.6
Verify again OK

8. Install Python2.7.13 (CentOS7-> Python 2.7.5)
Wget https://www.python.org/ftp/python/2.7.13/Python-2.7.13.tar.xz
Xz-d Python-2.7.13.tar.xz
Tar-xvf Python-2.7.13.tar
Cd Python-2.7.13
./Configure -- enable-shared
Sudo make
Sudo make install

Change permission to root
Yum install unzip
Unzip master.zip
Cd vim-master
Cd src/
./Configure -- with-features = huge -- enable-python3interp -- enable-pythoninterp = yes -- enable-rubyinterp -- enable-luainterp -- enable-multibyte -- enable-csures

15 cleanup
After clang is compiled, you do not need to install it. Just to get libclang. so has been copied to/usr/clang_351
Python2.7 is also temporary. Third-party libraries do not need to be installed as clang dependencies.
Gcc can also be temporary, used to compile clang, and libstdc ++. so can be obtained.

After cleaning, the space is not reduced much !!!!!!!!!!!!!!!!!!!
